三、按课文内容填空。

1、课文是按照事情发展顺序写的，先写了，接着写了，着重写了，最后写了。

四、多项选择：

从文中哪里可以看出诸葛亮“神机妙算”？正确的打“√”。

①他知道第三天四更时分一定有大雾。（）

②他算好了受箭的方法，二十条船可以绳索相连，一字排开，两面受箭。（）

③他算好了人，知道鲁肃忠厚诚信向他借船没事，周瑜聪明过人，曹操生性多疑。（）④诸葛亮能算，因为他是神仙。（）

五、品味探究。

1、“鲁肃回来报告周瑜，果然不提借箭的事，只说„„”

从这句话中，我感受到鲁肃。

2、从“诸葛亮又下令把船掉过来，船头朝东、船尾朝西，仍旧擂鼓呐喊”从这句话中，我感受到诸葛亮。

3、“雾这样大，曹操定不敢派兵出来。我们只管饮酒取乐，天亮了就回去。”

这段话是对说的，表现了他的特点。

4、从“曹操下令说：‘江上雾大„„不要轻易出动。只叫弓弩手朝他们射箭„„’”从这句话中，我感受到诸葛亮，曹操。

1.Taking frequent short breaks is better for you than one long holiday, psychologists have found.1 believe that people who use their holiday allowance in bursts 2 all in one go are happier.They claimed that people who 3 so-called mini-breaks have more 4 memories than those who spend their holidays for an extended period of time.Dan Ariely, a famous behavioural economist who 5 The Upside of Irrationality, suggested that holidaymakers 6 extended time away by doing some work in the middle of their break 7 this would make them more appreciative of their time away from the 8.The explanation is that people’s enjoyment wanes(减弱)as they become 9 to their holiday lifestyle.Professor Ariely, who 10 at Duke University in North Carolina, said, “On a long 11 , day seven is not as good as day one 12 it is not as exciting.That’s why 13 , going away four times a year provides more 14 than you would expect, and going away for one 15 is not as good as you would expect.”

1.根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Imagine that you are swimming in the middle of an ocean.You look down and see a wonderful underwater land of colours and fish of all shapes and sizes.This is the huge and colourful land of coral and the home of millions of different fish.1 Therefore, most coral reefs started developing over 10,000 years ago.Coral reefs are living structures built up over thousands of years by tiny animals called polyps(珊瑚虫), which usually live together in groups.Each polyp makes a stony skeleton(骨骼)around its body, and the skeletons of all the polyps in a group are joined together.When

the polyps die, their bodies decay.Their hard skeletons remain behind.2 Gradually, over long periods of time, reefs of coral skeletons are built up in the ocean, with living coral on the surface.3 It stretches for more than 1300 miles along the Northern Eastern coast of Australia.The Great Barrier Reef has more than 2600 kinds of coral altogether.It is the largest group of coral in the world.All together, it covers an area about half the size of Texas.The Great Barrier Reef does a lot of things for a lot of people, not just fish.It gives the fishermen plenty of fish, gives the tourists something to look at, and gives the scientists something to study.4 This happens by pollution and throwing anchors on the Great Barrier Reef.Worldwide, there are more than 4000 kinds of reef fish.The Great Barrier Reef supports about 1500 different species of fish.Some of the fish that live in it are crabs, sea turtles, sea sponges, and colourful marine worms.5 Those are only some of the species out of the thousand, and still we find more species every year.However, if we don’t start protecting the reef the fish will be in danger or eventually die.A.Coral only grows a few inches each year.B.New polyps grow on the top of the ones that died.C.You realize it is the home of millions of different fish.D.Here are some facts about coral that are really interesting.E.The Great Barrier Reef is one of the earth’s natural wonders.F.However, many people kill parts of it, and it is in danger of extinction.G.Also, you would probably see a big blue starfish, snails with beautiful shells and sharks.Ⅴ.短文改错

限时作业1(必修1 Unit 1)Ⅰ.完成句子

1.on purpose 2.a series of 3.fell in love 4.were packing up 5.was tired of Ⅱ.语法和词汇知识

1.B 在It’s high time that...句型中, 从句通常用虚拟语气, 谓语动词用一般过去式。句意:我认为的确到我们采取有效措施阻止事故发生的时候了。故B项正确。

2.B 这是一个强调句, 被强调的部分是in Beihai Park, 其后跟有where引导的定语从句。句意:这对老夫妇就是在他们第一次约会的北海公园里给我们讲了他们的爱情故事。for the first time作状语修饰made a date, 故B项正确。

3.C 句意:——你还相信爱吗?——非常相信。不是时间、金钱、权力而是爱能治愈我们的痛苦。这是一个强调句, 被强调部分用not...but连接。

4.A 句意:面对恐怖主义的威胁, 他们同意将政治上的分歧放在一边, 团结起来保卫国家的安全。set aside “把„„放在一边”;set about “开始着手(做„„)”;set off “出发, 引爆”;set up “建立”。根据句意选A项。

5.A 考查非谓语动词及被动语态。concerned...此处为过去分词短语作后置定语, 修饰all those;后一个空应用过去分词构成被动语态。句意:所有那些关心贫困儿童的人都应该受到感谢。6.A 考查强调句型的特殊疑问句。由or可以判断, 此句中疑问词用which, which后用疑问语序, 而which 又是强调句中被强调的部分, 因此强调句中用that, 故选A项。

7.A “in order to + 动词原形”引导目的状语;so that 和in order that引导从句;because of 引导原因状语, 后面接名词或动词-ing形式。句意为:游客们为了在十点以前到达云台山, 很早就出发了。

8.D not...until的强调句型为:It is/was + not until...+ that/who...。

9.D 句意:我以前经常跟父母吵架, 但现在我们相处得很好。look out “当心, 小心”;stay up “熬夜, 挺住”;carry on “继续, 进行”;get along “相处”, get along well “相处得好”。从前面的quarrel a lot和but可知, 这里指 “相处得好”。

10.B 句意:我们大家都知道, 好朋友会让生活更幸福、更有意义。as引导非限制性定语从句, 用逗号和主句分开了。add...to...“把„„增加到„„, 为„„增添„„”;add to “增加, 增添”;add up “加起来”。

11.B 句意:我们都被这个受骗后被卖到山村的小女孩的经历震惊了。go through “经受, 经历”;get through “通过, 用完, 完成”;live up to “达到, 符合, 不辜负(别人的期望)”;go against “反对, 不利”。根据句意选B项。

12.D make + 宾语 + 宾语补足语(多由名词、形容词、动词原形或过去分词来充当)意思是 “使„„”。题干中make用作了被动语态, 形容词possible作主语补足语。句意:现代科学技术的发展已经使得太空探索成为可能。

13.D You are always energetic意为 “你总是充满活力”。powerful “强大的, 有力的”;weak “虚弱的, 薄弱的”;forceful “强有力的, 坚强的, 有说服力的”;energetic “精力充沛的”。故D项正确。

14.D 句意:——大卫, 我是弗兰克。你有几分钟时间吗?我想见你。——我想我有时间, 但我希望几分钟别变成一小时。I’m afraid not “恐怕不行”;It doesn’t matter “没关系”;I don’t think so “我想我没空”。根据句意, 选D项。

15.D I guess not意为 “我不那么认为”。根据所提供的情景, 可判断说话人不同意对方的观点。句意:——这个男孩的词汇量有限, 是吗?——我不那么认为。他的词汇量很大。Ⅲ.完形填空

1.C 本文叙述了一项关于长假与短假带给人们的不同心理感受的研究成果, 所以这里指研究人员。2.A 前后的成分对比, 用rather than, 表示“而不是”。心理学家发现, 人们度短假比度长假更开心。

3.B 根据前句中who use their holiday allowance in bursts可知, 这里指度短假的人, 故用take。4.C 根据第一段中is better for you可知, 度短假的人有更快乐的回忆。5.D 丹·艾瑞里 “写” 了这本书。

6.C 根据句中doing some work in the middle of their break可得出答案。break up“分开, 打破”。

7.D 后半句内容为丹·艾瑞里发表的言论, 故用saying。8.A 这里指人们离开办公室去度假, 故用office。

9.D 根据语境可知, 当人们适应了假期的生活方式后, 他们的乐趣就会减弱。be accustomed to表示 “适应”。

10.C 根据艾瑞里的称谓professor判断, 他应在杜克大学教书。11.B 根据句中day seven和day one可知, 这里指在休一次长假的时候。12.A 从前后句意看是因果关系。

13.C 根据句中four times a year可知, 每年外出度假四次是从总体上来说的。14.B 根据句中is not as good as对比可知, 这里是度假带来的益处。

19.C 根据句中the same amount of leave可推断, 这里指如果把长假分三次来休。20.A 根据句中it’s not worth it可推断, 出行的麻烦就变为原来的三倍。Ⅳ.七选五阅读理解 1.A 2.B 3.E 4.F 5.G Ⅴ.短文改错

第五篇：XX中学限时作业实施方案

XX中学限时作业实施方案

为进一步推进教学改革，减轻学生课业负担，提高教育教学质量，特制定限时作业方案如下。

一、限时作业的实施要求

1.作业布置内容：

常规作业仅限于综合能力训练和学案上的部分习题，双休日作业限于配套练习册和由教师整理的专门双休日作业讲义，除此之外不得安排其它教辅材料上的习题。

2.作业内容要求：

以基础性习题为主，促进学生巩固基础知识，又要适当进行拓展，要设置一定量的探究性、实践性作业，以提高学生综合分析问题的能力，拓展性作业内容每次约占作业量的80%。

限时作业可以尝试教师指令性与学生自选性相结合的方式，特别是常规限时作业。即指令性2—4个题，自选性1—3个题。

3.作业时间：

①常规作业

6—9年级：语文、数学、英语课外作业书写时间控制在30分钟以内。物理、化学课外作业书写时间控制在20分钟以内。其他课外作业书写时间控制在15分钟以内。

班主任要协调各科作业的布置情况，每天要相互沟通，不要扎堆，不要增加过重的学习负担。

②双休日作业

6—9年级：语文、数学、英语作业书写时间控制在1小时以内。物理、化学作业书写时间控制在45分钟以内。其他课外作业书写时间控制在30分钟以内。

各年级要在周四前将作业布置情况上报教导处。

③节假日作业

6—9年级：语文、数学、英语作业书写时间控制在每天1小时以内。物理、化学课外作业书写时间控制在每天30分钟以内。其他课外作业书写时间控制在每天20分钟以内。

4.作业批改

①讲究及时细致批改作业。

批改要认真细致，杜绝只写“阅”字和日期等简单草率、不负责任的做法。另外应及时，不积压，原则上由教师全批全改和面批面改，或是在教师指导上的学生自改互改，一般情况上应在上新课前把作业批改好发给学生。

②讲究作业批改质量。

做到“五有五必”，即有发必收，有收必批，有批必评，有评必透，有错必纠。作业批改要作好记载与分析并及时适当点评，对典型性错误、共性问题应认真、及时讲评，要指导学生及时订正错题导学批改，重视作业的及时讲评反馈，要从作业中反思教学效果，以作业批改质量促进教学质量的提升。

③讲究作业批改规范化。

教师的批改一律用红笔，批改要有对错符号、日期、等级（或评分、评语）等。批改要使用规范、统一的批改符号，符号醒目，使学生清楚地知道教师的批改意图，有利于吸取经验教训，改正错误。成绩评定采取等级制。

④讲究用激励性的批语给予鼓励。

对于学生作业中的关键性错误要予以修正或以红线划出，提倡必要时加眉批或总批予以说明、指导。批语力求准确、精当、具体，富有激励性、启发性、针对性和指导性。

⑤讲究面批面改学生作业。

批改方式可多样化，依班额、年级和学生差异，采取重点批改、全部批改、部分批改、当面批改、学生自改、互改等形式，对边缘学生、学困生的作业提倡采用面批面改方式，更有利于学生明确、弥补知识的缺漏。

二、限时作业的实施措施

1.加强领导，整体推进。

高度重视，全员发动，整体推进，确保各个学科都能扎实开展。

分级领导：引领教师做好对重点工作的认识，研究制定落实限时性作业，修订教学常规实施要求。用规范引领教学改革。

业务校长、教导主任：研究制定实施方案或细则，指导教研组制定出各学科具体的实施办法，并对各教研组落实情况进行抽查。

教研组长：指导本学科所有教师做好限时性作业的落实，并对其检查、总结，不断创新工作的方法。

2.注重过程，量化管理。

实行“作业评估”制度，级部采取普查的方式，每周进行一次作业评估，将作业设计质量、作业完成情况、作业批阅及讲评情况纳入教师的业务考核之中。

三、限时作业布置、批改评价标准

学校教导处要不定期地对作业设计和批改情况全面检查或抽查，将检查和学生问卷调查结合认定结果。主要检查：作业量、批改情况、学生完成及落实情况情况，抽查时必须对上述三个方面做出结论：优、良、中、差，检查结果要纳入教师业务量化考核，同时与评优评先、考核挂钩。
