Why haven’t we found any pieces? “Matter and antimatter” are, in theory, created at the same time by the same event.However, while we have created antimatter in laboratories on Earth, we don’t see it in the universe around us.“Consciousness” is another mystery.What is the mind? Is it a mere side-effect of the way our brains work? Can consciousness survive the death of the brain that carries it? There is an enormous amount of matter in the universe beyond what we can actually see.We can only see about 4% of the stuff in the universe directly.Assignment: 1.Study Passage B, Passage C after class.2.Do the rest exercises on the textbooks.3.Study Unit 1 in Fast Reading(Book 3).Teaching Notes:

III课文精讲： P.190 第一段：
1.The problem of Jet Lag is one every international traveler comes across at some time.喷气飞机时差综合症是每个乘坐国际航班旅行的人在某个时候会碰到的问题
one是代词，代替a problem，后面every international traveller comes across at some time是定语从句，修饰先行词one，定语从句前省略了关系代词that或which；come across意思是“（偶然）遇到”；at some time相当于sometimes，意为“有时”。
2.But do you have to suffer? Understand what it is, and how a careful diet can minimize its worst effects, and your flights will be less stressful.Understand what it is„这是个祈使句，相当于一个条件状语从句：If you understand what it is„
例句：Work hard and you’ll succeed.相当于 If you work hard, you’ll succeed.该句可改写为：If you understand what it is, and how a careful diet can minimize its worst effects, your flights will be less stressful.所以，当有“Do„, and + 主语 + 动词 „”结构时，可把它改写为：“If you do „, 主语 + 动词 „”；what it is 和how a careful diet can minimize its worst effects是两个并列的宾语从句。第二段： 1.The effects of rapid travel on the body are actually far more disturbing than we realize.乘飞机旅行对身体的影响实际上远比我们意识到的更令人焦灼不安。
此句是个比较结构。disturbing 是分词式的形容词，比较级是more disturbing，far 用来修饰比较级。effect（影响）后面与介词on搭配，表示“对„的影响”，另有influence和impact后面可与介词on搭配；far可用来修饰比较级，可以替换为much或a lot或a great deal。2.Jet Lag is not a psychological consequence of having to readjust to a different time zone.adjust to是固定搭配，意思是“调整、适应”，故有readjust to。
3.It is due to changes in the body's physiological regulatory mechanisms, specifically the hormonal systems, in a different environment.due to意思是“由于、因为”，通常用作表语成分。第三段：
1.Confused? 是不是被弄糊涂啦？
该句是Are you confused?之省略。
2.So was John Foster Dulls, the American Secretary of State, when he flew to Egypt to conduct negotiations on the Aswan Dam.美国国务卿约翰·福斯特·杜勒斯从美国飞往埃及谈判阿斯旺水坝问题时就被弄糊涂了。他后来把自己在谈判中判断失误归咎于时差综合症。
当so（表示“也”）置于句首时，句子必须使用倒装结构，so 位于句首，表示前面所说的情况也适合于本句。由“So + 助动词 ／ 连系动词 ／ 情态动词 ＋ 主语 ＋ „”构成；这是一种部分倒装结构，常见类型有：
3.He later blamed his poor judgement on Jet Lag.blame „ on „意思是“把„归咎于„”；另有blame sb for sth，意为“因为某事而责怪某人” 第四段：
1.The effects can be used to advantage, too.to advantage意思是“有效地、有用地” 2.President Johnson once conducted an important meeting in Guam and kept the entire proceedings at Washington DC time.keep the entire proceedings at Washington DC time意思是“按照华盛顿时间安排议程”，keep是使动用法，此处是keep + n.+ prep.结构。
3.The White House working personnel were as fresh as paint, while the locals, in this case, were jet-lagged.该句是由 while 连接的两个并列句，表示前后对比。in this case 作状语，译为“在这种情况下，” the locals 是指关岛的本地人，作主语。personnel在此处意思是“（全体）职员、（全体）人员”，表示复数概念，故谓语动词是were；as fresh as paint意思是“精神饱满 / 抖擞”；the locals 相当于the local people；jet-lag是动词，并用于被动语态，意思是“使患有时差不适症、使无精打采”。4.Essentially, they had been instantaneously transported to America.句首essentially意为“实际上”。P.191 第二段：
1.Now that we understand what Jet Lag is, we can go some way to overcoming it.既然我们了解了时差综合症是什么
句首的now that意思是“既然”；动词understand后接宾语从句what Jet Lag is；go some way to doing sth意为“想办法做某事”。
2.A great number of the body's events are scheduled to occur at a certain time of day.a great number of意思是“许多、大量”；schedule由名词转化为动词；to occur充当句子的主语补足语。
3.Naturally these have to be regulated, and there are two regulatory systems which interact.these指代上句的the body's events。第三段：
1.One timing system comes from the evidence of our senses and stomachs, and the periodicity we experience when living in a particular time zone.一个定时系统来自我们的感官和胃肠饥饿感以及我们在某个特定时区所经受的周期性变化
该句主干结构是“one timing system comes from„.”;from 有两个宾语，由and 连接。we experience是定语从句，修饰the periodicity，关系代词that / which因作宾语而被省略；when living in a particular time zone是由连词when + 现在分词短语构成的时间状语。
2.The other belongs in our internal clocks(the major one of which may be physically located in a part of the brain called the suprachiasmatic nucleus)which, left alone, would tie the body to a 25 hour--yes, 25--rhythm.另一个定时系统在我们的体内时钟内（其中一个主要时钟可能位于我们大脑的称为超交叉核的那部分中）这些体内时钟在不受干扰时，会使人体有一个25小时——是的，25小时——的生理节奏。
该句的主干结构“The other belongs in our internal clocks „”，which 引导定语从句修饰our internal clocks。在定语从句中，left alone 是过去分词词组作条件状语，相当于条件状语从句If it is left alone。括号中的定语从句也修饰our internal clocks。belong in意思是“存在于”；“名词 / 数词 / 代词 + of + 关系代词”引导非限制性定语从句；be located in意思是“位于”；called the suprachiasmatic nucleus是过去分词短语，修饰前面的名词a part；leave „ alone意为“听其自然、不理、不管”。
3.Normally the two timers are in step, and the external cues tend to regularize the internal clocks to the more convenient 24 hour period.in step意为“步调一致”；tend to意思是“倾向于”；regularise „ to „意思是“把„调整到„”。第四段：
1.If, however, you move the whole body to a time zone which is four hours different, the two clocks will be out of step, like two alarm clocks which are normally set together, but which have been reset a few hours apart.然而如果你把整个身体移到一个时差4个小时的时区，两个时钟就不再同步，正像两个闹钟通常被一起定时，但现在定时相差几个小时。
however 是插入语，意思是“然而”； “which is four hours different”是定语从句修饰zone。which „和but which „是两个并列的定语从句，修饰前面的two alarm clocks。out of step意为“乱了步调”；
2.Whereas the two clocks would normally sound their alarms together, now they ring at different times.尽管两个闹钟通常同时报时，但现在则在不同时间报时。
whereas连接让步状语从句，意为“尽管，虽然”
3.Similarly,the body can be set for evening while the sun is rising.第五段：
1.In time the physiological system will reset itself, but it does take time.经过一段时间后，生理系统将会自我调整过来，但这需要时间。
句首的in time意思是“终于、经过一段时间以后”；it does take time意为“这确实要花时间的”，其中does是助动词，用以加强语气。2.One easily monitored rhythm is palm sweating.monitored是过去分词，修饰rhythm，作定语，表示被动意义。
3.A man flown to a time zone different by 10 hours will take eight days to readjust his palm sweat.flown to a time zone different by 10 hours是过去分词短语，作a man的定语。
4.Blood pressure, which is also rhythmical, takes four days to readjust.血压也是有节奏性的，需要4天才能调整过来。
which is also rhythmical是非限制性定语从句，修饰前面的blood pressure。第六段：
1.One reason for this discrepancy is that different bodily events are controlled by different factors.此句是一个表语从句，that 引导一个从句作表语。reason常与介词for搭配，表示“„的理由”；
2.The hormone cortisol, which controls salt and water excretion, is made in the morning, wherever the body is.出现这种差异的一个原因是人体的不同活动受到不同因素的支配
which controls salt and water excretion是非限制性定语从句，修饰the hormone cortisol；wherever the body is是地点状语从句或让步状语从句。
3.But the growth hormone is released during sleep, whenever in the day that sleep occurs.但生长激素在睡眠时才分泌，而不论一天中什么时候睡觉。
whenever Whenever in the day 意为“不管在一天中的什么时候”；whenever in the day that sleep occurs中whenever是副词，意思是“无论什么时候”。引导时间状语从句。that sleep 是从句的主语，that 是指示代词修饰sleep。
4.Normally these two hormones are separated by seven or eight hours, but if the body arrives at a destination in the early morning(local)and goes to sleep as soon as possible, the two hormones will be released simultaneously.该句是并列复合句，中间以but连接，第一分句是被动语态，第二分句中if the body arrives „ and goes to sleep as soon as possible是条件状语从句，the two hormones „ simultaneously是主句。P.192 第二段：
1.What can we do about it?
it指上文所说的 the two hormones will be released simultaneously这件事。2.It is not feasible to wait four days until the body is used to the new time zone.句首it是形式主语，真正主语是to wait „；be used to意思是“习惯于”。3.Fortunately there is a short cut.4.It relies on two things--the power of the stomach to regulate the timing of other events, and the pharmacological actions of coffee.rely on是固定搭配，意思是“信赖、依赖、依靠”；破折号后面的两个并列的名词短语是two things的同位语成分。第三段：
1.The basic assumptions are: 第四段：
1.Coffee delays the body clock in the morning, and advances it at night.it指代本句的the body clock。
2.Coffee at mid-afternoon is neutral.下午三点左右喝咖啡对人体时钟不起作用。
该句中neutral 意为“中性的”，在这里是与上文的delay 和advance 相对，表示“既不推迟，也不提前”
第五段：
1.Protein in meals stimulates wakefulness, while carbohydrates promote sleep.while意为“而”。第六段：
1.Putting food into an empty stomach helps synchronize the body clock.help do sth意思是“有助于做某事”。Jet Lag: Prevention and Cure Unit 8 常考句子：

形容词、副词比较级的用法

2)There is often resistance to the idea that it is because the birthrate fell earlier in Western and Northwestern Europe than elsewhere, rather than because of any change in the death rate, that we have grown so old.(Unit 9)2．比较级前面可以用much, far, a lot, a great deal, a little, a bit 等词或词组修饰，表示“…得多”，“稍微…”等意义，如：
1)The effects of rapid travel on the body are actually far more disturbing than we realize.2)We have among us a very much greater experience of continued living than any society that has ever preceded us anywhere,…(Unit 9)
3.用“the + 比较级，the + 比较级”的结构表示“越…，越…”的意思，如：

2)The older you are now, of course, the greater this proportion will be, and greater still if you are a woman.(Unit 9)
4.还可以用连接两个相同的比较级，表示“越来越…”，注意与用法3相区别，如：

课文精讲
P.203 第一段：
1.Psychologically defined, concentration is process of centering one's attention over a period of time.句首psychologically defined是过去分词短语，充当条件状语，相当于if it is psychologically defined。
2.In practical application, however, concentration is not as simple to deal successfully with as the definition may imply.however（然而）是插入语成分；not as „ as „是原级比较的否定结构；simple后面可跟to do，表示被动意义，另有difficult / hard / easy + to do。
3.For this reason, it is helpful to keep the following points in mind.因此，记住下列几点是很有帮助的。
for this reason意思是“因为这个理由”；keep „ in mind意为“把„牢记在心”。be helpful to ….对… 很有益； 第二段：
1.Even with the greatest effort, our span of attention fluctuates.Even with the greatest effort意为“即使尽了最大的努力”。2.You can demonstrate for yourself this fluctuation of attention.demonstrate的宾语是this fluctuation of attention。
3.In a quiet room, place a watch so that it can just scarcely be heard.在一个安静的房间里，放一块表，表的声音几乎刚刚能听见。
该句主句是祈使句 place a watch;so that 引导目的状语从句;scarcely是否定副词，相当于hardly。
4.Listen carefully and notice how the ticking increases in apparent intensity, fades to a point where it cannot be heard, and then increases again.注意听表的走动声，并且注意表的嘀嗒声怎
样明显增大，然后小到听不见，然后又变大。
how 引导宾语从句，从句中有三个并列的谓语动词：increases „, fades „, and then increases again。where it cannot be heard 是定语从句修饰 point 5.This phenomenon reveals how our span of attention fluctuates, for the intensity of the ticking is actually constant.该句为并列复合句，由for连接两个分句，第一分句中有how引导的宾语从句。第三段：
标题：pay attention to意思是“注意”；试比较at a time和at one time：前者意为“一次、每次”，后者意思是“一度、曾经”。
1.Evidence to date indicates that you attend to one idea at a time.to date意思是“到目前为止”；attend to表示“专心、注意”。
2.It is possible for your attention to shift so rapidly that it seems that you attend to several concepts at once.你的注意有可能转移得十分迅速，以至于好像你同时能够专心于几个想法。
句首的it是形式主语；该句句末的at once意思是“同时、一次”。so …that…结果状语从句
3.But apparently this is only an illusion.4.In high concentration the shift from the focus of attention is of short duration and relatively infrequent.be of是一固定搭配，意思是“具有”。第四段：
1.High attention has long periods of attending and short distraction periods.2.In low attention the periods of attending are short and the distraction period long.long前面省略了连系动词are。
3.In moderate attention there is a mixture of the extremes.4.Thus it is easy to see that it is highly unlikely that the student who has most of his attention centered on fancying at large will be able to recall even the major points of a lecture.这样我们可以很容易地看到，如果一个学生的大部分注意力用于自由幻想，即使是讲课要点，他也不可能回想起来。
句首it是形式主语，真正主语是to see „；不定式to see后面有that引导的宾语从句，其中it也是形式主语，that the student „是主语从句，在主语从句中，the student后面有定语从句who has most „ at large，该定语从句中含有have sth done结构、center one's attention on和at large（不受拘束、不受控制、自由自在、逍遥法外）等短语。P.204 第二段：
1.Lack of concentration is a symptom, not the cause, of difficulty.该句相当于：Lack of concentration is a symptom of difficulty, not the cause of difficulty.2.When a student says “I can't concentrate”, what he is really saying is, “I can't attend to the task at hand because my distractors are too strong.”
attend to意思是“集中精力于”；at hand意为“手边”。第三段：
标题：be of可译为“具有”。
1.A distractor is anything which causes attention to vary from a central focal point.通常情况下，在anything, something, nothing, everything后面的关系代词是that，而不是which，本句说法不很规范。2.In the study situation distractors may be thought of as either psychological or physical in nature.在学习的情况下，干扰物实际上可以被认为是心理的或者是物质的。
think of „ as „意思是“把„看着”；either „ or „意思是“或者„或者„、要么„要么„”。
3.Both types of distractors must be understood before the student can attempt to remedy his lack of concentration.before引导时间状语从句。第四段：
1.The angry man forgets the pain of injury, the fearful man finds it difficult to enjoy pleasure and the tense or anxious person may react violently to the smallest of matters.愤怒的人会忘记伤痛，人害怕的时候很难享受快乐，人在紧张或焦虑的时候可能对非常小的事情做出强烈的反应。
该句由三个并列分句构成，第二分句中，it是形式主语，真正主语是不定式短语to enjoy pleasure，第三分句中react与to是固定搭配，意思是“对„作出反应”。另有：reaction to, respond to, response to等搭配。
2.In the student's life there are many psychological pressures and tensions which block effective productivity.which引导定语从句，修饰前面的many psychological pressures and tensions。
3.The fears about making the grade, the doubts of the friendliness of a friend's behaviour and the pressures of limited finances--these are only a few of the emotional forces which affect the student.these指代破折号前面的三个并列的名词短语：The fears „, the doubts „ and the pressures „；emotional forces译为“情感因素”。第五段：
1.Emotional reaction varies greatly from person to person.人与人的情绪反应差异很大。
vary from „ to „意思是“因„而异、因„而变化”。
2.Some persons gain goal and direction from their tensions and actually do better because of them.because of是短语介词，意思是“因为”，后接名词短语。
3.Others fall apart under pressure, while a few people do well despite the pressure.fall apart意思是“崩溃”；under pressure“在压力下”；despite与in spite of 同义，意思是“尽管、虽然”。P.205 第二段：
1.Our environment is much more important to how we feel and react than we often think.环境对于我们如何感觉和反应的重要性比我们所想的要大得多。
.how we feel and react 是介词to 的宾语从句；much more … than … 结构表示“远比…要…得多”than引导比较状语从句。
2.Particularly is this true of the effect of physical distractors on mental tasks.物理性干扰对需要动脑筋完成的作业的影响尤其如此。
该句为倒装结构，正常语序为：This is particularly true of the effect of physical distractors on mental tasks.名词effect（影响）后面常与介词on搭配；另有：influence on, impact on搭配。
3.One research report has shown that comprehension and retention of reading were decreased when students listened to lively music.该句是主从复合句，has shown后面有that引导的宾语从句，该从句中又有when引导的时间状语从句。
4.However, rate of reading was not affected, so that many students were not aware that they were affected by the background distractor.so that引导结果状语从句，译为“结果、因此、所以”；be aware that意思是“意识到”；另有be aware of, be conscious of, be conscious that等搭配。be＋形容词＋that从句“这类结构后面，that引起的从句在概念上接近宾语。能接这类从句常见的形容词有：aware, sure, certain, convinced, confident等。例如：We are fully confident that we can surmount these difficulties.我们完全相信能克服这些困难。
5.Another study found that the ability to recall accurately was affected by distracting conditions.to recall accurately是不定式短语，修饰名词the ability。
6.Most of the evidence indicates that noise affects adversely higher mental task output.evidence是不可数名词；that引导宾语从句。
7.Still, the effect of distractors is seldom fully appreciated by students.有些副词如still, though, however, otherwise.等在句子中起链接词的作用，使句子和前面说的话连接得更紧密一些.appreciate意思是“正确评价、鉴别、认识”。第三段：
1.Many routine tasks can be performed with distraction in the background with little or no adverse effect on output.with distraction in the background和with little or no adverse effect on output都是含有介词with的独立结构。该结构是：
2.Most students have found this fact to be true from their own experience.to be true是宾语补足语成分。
3.They may have had high school homework which was drill or merely copying assignments.may have had中情态动词may表示可能性，此处是对过去的一种推测。
4.It was possible to do such work with the latest recordings or the television set playing in the background.句首的It作形式主语，真正主语是不定式短语to do such work „；with the latest recordings or the television set playing in the background是独立结构，由with + 名词 + doing构成。
5.In time such students began to feel certain that they could do all work--routine or problem-solving--in the same manner.最后（终于）这些学生开始确信，他们能用同样的方式完成作业，无论是常规性的还是解决问题性的。
句首in time意思是“逐渐地、最终、过了一段时间以后”。feel certain 相当于feel sure，意为“感到肯定”本句中that引导宾语从句，6.The evidence indicates the contrary conclusion.第四段：
1.Typically when students are faced with the evidence on distractors the argument is given that their cousin, friend, or classmate can study in “Grand Central Station.” 典型的情况是，当要求学生们拿出关于干扰物的证据时，他们提出自己的表兄弟、朋友或同学能在纽约的“中央火车站”学习。
be faced with意为“面对、面临”；when引导时间状语从句；that引导的是主语the argument的同位语从句。
2.And he makes “all A's” too!3.There is evidence, of course, that motivation plays an important role in overcoming the effects of distractors and that there are considerable differences in individual spans of attention.当然，有证据表明，学习动机在克服干扰的影响方面起作用，并且每个人的注意力广度相差很大 play a role / part in „意思是“在„方面发挥作用 / 在„中扮演角色”；evidence后面有两个that引导的并列的同位语从句。
这两种因素中哪一种都能解释某些人用效率不高的方法都能学得很好。
5.The fact that some exceptional people do well under adverse conditions scarcely justifies your assuming that you are exceptional in the same manner.一些特殊的人在不利条件下能学得好，这一事实绝不能证明，你有理由认为自己在同样的条件下也是特殊的。
第一个 that 引导同位语从句，第二个that 是动名词assuming 的宾语从句
justify 意为 “证明…”，它的宾语是动名词assuming，物主代词your 是动名词assuming的逻辑主语。your assuming „也是动名词短语的复合结构。
6.Your chances of success are higher if you avoid the distractors which are known to hinder the typical student.chances在此意思是“可能性”。
语法 练习
一、补充语法知识
形容词和副词的比较级
1.比较级+than
steel is harder than iron.2.用词或词组修饰比较级，表示强调或稍微。
3.the+比较级，the+比较级：越来越…The nearer an object is to us, the larger it looks.比较级重复，4.more and more越来越多
colder and colder越来越冷
注意事项：
1.n.的可数与不可数，修饰可数名词用“few”“a few”，所以比较级“fewer”后面接的也是可数名词。但是“less”即“little”的比较级也修饰不可数名词。
2.没有比较级的词：如empty

2． Revise the contents in Unit 7．
3． Check homework by asking some students to read their sentences they’ve made with the verbs． Let them hand in their homework．
4． Dictate ten words in Unit 7．
Step Ⅱ la
In this unit we learn to offer to help．We’ll use some phrasal verbs． Each phrasal verbs has two or three words, such as clean up, cheer up, give out． Here is an example on how to use clean up． Look at the title of Unit 8． I’ll help clean up the city parks． Repeat it twice, please．
Ask the students to read the title twice．Then go on saying, “clean up means make a place clean and tidy, put things there in order”． Let’s see another example, We should always clean up after a picnic．Who can explain this sentence in your own, words?Ask one student to explain the sentence．
He or she may say like this． This sentences means we should burn wastepaper, collect litter and empty bottles, etc．Then ask the class． Who can make more sentences
with clean up?Ask several students to share their sentences to the class．Do the same with the other phrasal verbs．
Read the instructions to the students．
Please look at the picture now． We can see a bulletin board and two children in it． What is the bulletin board about? Help students to answer: Volunteer Today!Then continue saying, “Who can tell me the meaning of volunteer?”
Ask one student to try to explain it． Then tell them the meaning of it． Volunteer means a person who offers to do something unpleasant or dangerous． It means a person who offers to help the others sometimes． Volunteer is used as a verb in this lesson．
Draw the students’ attention to the three posters on the board．We can see one sentence in each poster．And we can see some people in each poster, too． What are the volunteers doing in each poster? Please work in pairs and talk about the posters．
Give the students a few minutes to talk about what they will say． Let them talk about all the three items． Move around and help the pairs as needed．Then read the sentences in the posters to the class． Ask the pairs of students to explain what the sentence means in their own words． Or tell what the volunteers are doing in the posters．For example, for the first poster, a pair might say:
It means there is trash in the park． There are papers on the ground． We can help clean up the park by picking up papers and trash． We can make the park clean．
After the students have finished all the items, ask the students to add some other ways they can help people． Get them to write the ways down in the box below the picture．
At last, ask some students to share their ideas with the class． Write any new words or phrases on the board and explain these words to the class, if necessary． Step Ⅲ 1b
Call the students’ attention to the two lists in the box in Activity lb． Ask some students to read the eight sentences on the lists to the class． Explain any new words and phrases in it．
Make sure that all the students can understand the meanings of the eight items．Then get the children to read the instructions together．
Say, we will hear four conversations．
Your task is to match the items in the two lists． We can see the blanks in fro
nt of the first line of each conversation． Listen to the conversations and write the letter in front of the first line of each conversation． Put the letters of the second line of conversations in right places． Point out the sample answer to the class．
Play the recording the first time． Tell the students to only listen． Then play the recording a second time．

Step Ⅳ 1c
Read the instructions with the class．Call their attention to the example in the speech bubbles in Activity la． Ask a pair of students to read this conversation to a class． Then let them practice in pairs．
Note their pronunciation of “like to” in phrases such as, I’d like to help hungry people． Tell them English speakers usually pronounce the words “like to” as if they were spelled like-tuh．
Play the I’d like to statements on the recording to demonstrate this
pronunciation．After they’ve finished practicing the sample conversation, ask them
to make up similar conversations based on the other two posters． Get two pairs to demonstrate two conversations first．
Then let the whole class practice in pairs．After that, play the recording of activity 1b and let the children read after it twice．Then ask them to practice similar conversations using the information in Activity 1b．

Read aloud the conversation in groups, then present the comic strip on the screen for the Ss to act out the conversation.Step 7.Explain 1.wear 穿着，戴着（表示穿、戴的状态）
put on 穿上，戴上（表示穿戴的动作）
e.g.She likes wearing red.她喜欢穿红色。
It’s cold outside.Put on your coat.外面冷，穿上外套。2.think about sth.考虑某事；想起某事
e.g.She is thinking about how to spend her holiday.她正考虑如何度假呢。Don't think about it any more.不要再去想这事了。
3.what to wear
意思是“穿什么”，英语中“疑问词+ to do ”是一个短语而不是句子。
e.g.I don’t know what to do.我不知道该怎么办？
Let me tell you how to do it.让我告诉你如何做这件事。4.spend vt
花费，度过
常用结构(1)Sb.+ spend +time/money doing sth.(2)Sb.+ spend + money on sth.e.g.He spends a lot of time playing football every day.他每天花大量时间踢足球。
How much does she spend on clothes every year? 她每年在衣服上花多少钱？
5.spend ten more minutes = another ten minutes
再花十分钟 e.g.We need five more chairs.6.lend sb.sth.= lend sth.to sb.把某物借给某人
e.g.Can you lend me your bike? 你能把自行车借给我吗？= Can you lend your bike to me? 注：lend 是“借给”，而英语中的borrow
是指句子的主语将东西借进，含义是“借来”。常用结构是borrow sth.from sb.“向某人借某物”。e.g.Can I borrow your rubber? 我可以借用你的橡皮吗？ Step 8.Exercises
一、根据Millie 与Mum的对话内容填空：

女士，夫人
gentleman
(pl.gentlemen)先生;君子 style
风格，样式 trainer

两者（都）jeans
（复）牛仔裤 silk

both… and …
…和… 都；不仅…而且… be made of … 由… 制成 Step 2.Lead-in
Present two pictures about a fashion show and ask: What are they doing? Are you interested in it? Step 3.Reading
1.Listen to Millie’s article and answer the questions:
1)Where do they hold the fashion show? 2)How many students are there in this show? 2.Read the article and complete the form:
3.Complete B1 on Page 95.4.Read aloud the article and put T or F in the blanks.5.Complete B3 & 4 on page 96.Step 4 Homework
1.Read aloud the article and underline the difficult parts.2.Remember the new words in this lesson.Reading II Teaching Aims: 1.Learn the language points in this article.2.Learn to describe a fashion show.Step 1.Revision The students are having a fashion show in the school _______ in the ________.Millie wears _______ clothes.She thinks trainers are __________ to wear, so they are popular _________ young people.Simon’s shirt is _______ and his trousers are ________.He looks _______.______ Amy _______ Daniel wears blue ________.Young people also like to wear them.Sandy looks ________ because she is in red _______ blouse, a ______ wool skirt and a pair of red __________.Step 2.Explain 1.trousers, jeans本身就是复数，其数量的表达要用 a pair of 这样的短语，这样的短语作主语时要由pair 的单复数形式来决定谓语动词形式。e.g.The jeans are popular among young people.There is a pair of jeans in the bag.The two pairs of trousers are different.2.look cool 看上去很酷
当look的译为“看起来，看上去” 的意思时是连系动词，这种动词后面可以接形容词作表语，但不能接副词，e.g.You look happy today.（正）（happy是形容词）
You look happily today.（错）（happily 是副词，不能作表语）
本课短文中的look cool, look smart，look modern中look都是连系动词。3.both 两者（都）
(1)这个词只能用于两者或两部分时，三者及以上的“全，都”要用all。e.g.His parents are both teachers.There are 40 students in our class.We are all Chinese.(2)“both of + 名词复数/ 宾格代词”作主语时谓语动词要用复数形式。
Both of them work in Beijing.（3）both … and …
…和… 都；不仅…而且… She can both sing and dance.她不仅会唱歌而且会跳舞。4.Here comes Sandy.西蒙来了。
这是一个以Here 开头的倒装句，句子的真正主语是Sandy。请观察here 开头的倒装句的两种不同情况：
Here comes the bus.(主语是名词the bus）
Here it comes.(主语是代 it）
Here you are.(主语是you)5.be made of …
由… 制成
Sandy’s blouse is made of silk.桑迪的衬衫是由丝绸制成的。6.be popular among …
在……中很受欢迎
Jeans are popular among young people.Step 3.Exercises

Help them to answer and tell them they are using the present continuous tense.Step 3.Grammar
一、现在进行时肯定句和否定句的构成：
肯定句:
主语+ am/ is /are + v-ing...肯定句:
主语+ am/ is / are not + v-ing...I am not eating.You/ We/ They are not eating.He/ She/ It is not eating.二、动词ing形式的构成：
Exercise 1: Complete Part A on Page 97.三、现在进行时一般疑问句的构成及回答： I am eating.→ Am I eating?
Yes, I am./ No, I am not.(或 No, I’m not.)
You/ We/ They are eating.→ Are you/ we/ they eating?
Yes, we/you/ they are.No, we/ you/ they are not(或用缩写aren’t)He/ She/ It is eating.→ Is he/ she/ it eating? Yes, he/she/it is.No, he/she/it is not.(或用缩写isn’t)规律：将be 动词移到主语前面。注意：肯定回答时主语be动词不能缩写，否定回答时be动词和not可以用完全形式也可以用缩写。
Exercise 2: Complete Part B on Page 98.四、语法补充：
（一）现在进行时可以表示说话时正在进行或发生的动作，也可表示当前一段时间内的活动或现阶段正在进行的动作。Look!He is reading in bed.(说话时正在进行）Mr Green is writing a new book.(现阶段正在做）
（二）现在进行时的判断方法：
如果句子中带有鲜明的时间状语，如：now, 或带有Look, Listen 等暗示动作正在发生，或有表示现在的上下文语境时，我们常用现在进行时。Listen!She is singing in the next room.—Where is your mother? — She is cooking dinner.（三）注意点：
（1）现在进行时的谓语动词由“be 的某种形式+ 动词ing 形式” 这两部分构成。这时be是个助动词，没有实际意思，只起构成时态的作用。同学们在使用现在进行时时千万不要忘了用be动词。
We having breakfast.(错）We are having breakfast.(正)(2)有些动词一般不用进行时，如：know, understand(理解), love, like, want, hope, hear, see等。
(3)双写末尾一个辅音字母再加ing形式的动词的条件参考书本P121。这个规律不易掌握，所以同学们可以在学习英语的过程中学到一个双写词就记住它，慢慢体会规律。以下是已经学过的一部分双写词：shop, run, get, swim, begin, stop, cut, hit，forget等。Homework Remember the new words in this lesson.Integrated skills
