2.Reading

①T says to Ss: Today we will read a passage about the historical development of English over the past fifty year, developing from a widely spoken national language to a universally spoken world language.②let Ss read the text silently, and then fill in blanks(slide show)1

The English is the mother tongue of 375 million people in English speaking countries such as the US, UK, Canada, Australia, New Zealand, South Africa and Ireland among others.2

The number of people who learn English as foreign language is more than 750 million.Most people learn English for five or six years at high school.3

English is the working language of most international organizations, international trade and tourism.English is also the language of global culture, such as popular music and the Internet.③let Ss read the text again, and then work in pairs to answer another questions:

Why is it becoming more and more important to have a good knowledge of English?

In which countries do we find most native speakers of English? Give the names of the three countries.Living in China you can use English every day in different situations.Give two examples.④ play the tape to Ss and let them follow and repeat the text.⑤ deal with some language points and new words

1.There many people speak English as a first or a second language.“ the+序数词”用来表示编号，强调“第„„”

e.g.Who is the first man to land on the moon?

“ a+序数词”强调“再一„„，又„„”

e.g.We’ll have to do it a second time.He had jumped two times but failed;he tried to jump a third time.2.Chinese businessmen, taxi drivers and students talk with them using English.Using English是现在分词短语做方式状语。现在份词作状语，表示主语正在进行的另一动作，对谓语表示的主要动作加以修饰和陪衬，分词动作与谓语动作都必须是同一主语进行的，它可以表示时间、原因、方式、伴随状况等。

e.g.Arriving at the bus stop, we found his sister there.表示时间

Seeing nobody at home, she decided to leave them a note.原因

Travelling by car, the girls visited many places.方式

They walked along the street, talking and laughing.伴随状况

3.There are more than 42 countries where the majority of the people speak English.大多数人讲英语的国家有42个还多。

more than意为“超过，不仅仅”，相当于over, not only。例如：

（1）There ar more than 2,000 students in our school.我们学校有2，000多人。

（2）He is more than 40 years old.他40多岁了。

（3）She is more than a teacher.She loves us ilke a mother.她不仅仅是个老师，她像母亲一样爱护我们。

where the majority of the people speak English是定语从句，修饰countries。where在定语从句中作状语，表示地点。又如：

（1）Last month I visited the village where I was born.上个月我去拜访了我出生的那个村子。

（2）Zhengzhou is the place where his father once worked.郑州是他父亲曾经工作过的地方。

majority是句词，意为“多数，大多数，半数以上”。例如：

（1）He was supported by the great majority of the people.他受到了广大人民群众的拥护。

（2）The majority of his books are kept upstairs.他的大部分藏书在楼上。

（3）The majority were/was against the plan.多数人不赞成这个计划。

4.However, the number of people who learn English as a foreign language is more than 750 million.然而，把英语作为外语来学的人有7亿5千万。

the number of/a number of 辨析

the number of意为“„„的数目，„„的号码”作主语时，谓语动词用单数；a number of意为“一些，许多”，作定语，修饰复数名词，作主语时谓语动词用复数。例如：

（1）The number of the students in our school is more than 2,000.我们学校有2，000多人。

（2）The number of my telephone is 0371-6949192.我的电话号码是0371-6949192.（3）A number of students in our class have been to Beijing.我们班有很多同学去过北京。

使学生知道物理中的一种研究问题的方法——控制变量法

教学重点

1．牛顿第二定律的实验过程；

2．牛顿第二定律。

教学难点

牛顿第二定律的意义。

教学方法

实验法、讲授法、归纳法

教学用具

两辆质量相同的小车，光滑的水平板（一端带有定滑轮）；砝码（一盒），细绳、夹子 课时安排 2课时

教学过程

一、导入新课

1．提问：什么是物体运动状态的改变？物体运动状态发生改变的原因是什么？

2．引入新课：

通过上节课的学习，我们已知道：物体运动状态改变时产生加速度，而产生的加速度又和物体的质量及所受力的大小有关，那么：加速度跟物体所受力的大小及物体质量之间有什么关系呢？本节课我们就来研究这个问题。

二、新课教学

（一）用投影片出示本节课的学习目标：

1．理解加速度与力的关系；

2．理解加速度与质量的关系

3．理解牛顿第二定律的内容。

（二）学习目标完成过程：

1、加速度和力的关系：

（1）用投影片出示本节课所用的实验装置，教师进行讲解：图中是两辆质量相同的小车，放在光滑的水平板上，小车的前端各系上细绳，绳的另一端跨过定滑轮各挂一个小盘，盘里放有数量不等的砝码，使两辆小车在不同的拉力下做匀加速运动。

（2）对本次实验中说明的两个问题

a：砝码跟小车相比质量较小，细绳对小车的拉力近似地等于砝码所受的重力。

b：用一只夹子夹住两根细绳，以同时控控制两辆小车。

（3）实验的做法：

a：在两砝码盘中放不同数量的砝码，以使两小车所受的拉力不同。

高考资源网 2006精品资料系列

b：打开夹子，让两辆小车同时从静止开始运动，一段时间后关上夹子，让它们同时停下来。

（4）需观察的现象，观察两辆车在相等的时间里，所发生的位移的大小。（实验现象：所受拉力大的那辆小车，位移大）

（5）分析推理：

a：由公式s1at2得到在时间t一定时，位移s和加速度a成正比；

2b：由实验现象得到：小车的位移与他们所受的拉力成正比。

c：推理得到结论：对质量相同的物体，物体的加速度跟作用在物体上的力成正比，即：

a1F1或aF a2F2a1F1a2F2

（6）巩固练习：

a．据得到：要使物体在短时间内速度的改变很大，即加速度很大，就必须给物体提供。

b．竞赛用的小汽车，要求起动后几秒钟内速度由零达到60m/s以上，他们为什么要装备功率很大的发动机？

2：加速度和质量的关系：

（1）实验装置同上；

（2）说明与前次实验的不同。

前一次实验中，我们是保持小车质量不变，而改变小车所受力的大小，来研究加速度和力之间的关系的。

本次实验是使两辆小车所受拉力相同，而在一辆小车上加放砝码的，以增大质量，研究加速度和质量之间关系的。

（3）实验现象：

在相同的时间里，质量小的那辆小车的位移大。

（4）分析推理，得到结论：

在相同的力作用下，物体的加速度跟物体的质量成反比，即

a1/a2=m2/m1或a∝m3：牛顿第二运动定律

（1）综合上述实验中得到的两个关系，得到下述结论：

物体的加速度跟作用力成正比，跟物体的质量成反比，且加速度的方向跟引起这个加速度的力的方向相同。

（2）公式表示：

a∝F或者F∝ma m即：F=kma

a：如果每个物理量都采用国际单位，k＝1；

高考资源网 2006精品资料系列

b：力的单位（牛顿）的定义：使质量为1千克的物体产生1m/s2的加速度的力叫做1牛顿。

（3）推广：上面我们研究的是物体受到一个力作用的情况，当物体受到几个力作用时，上述关系可推广为：

物体的加速度跟所受的合力成正比，跟物体的质量成反比，加速度的放心跟合力的方向相同。即F合＝ma。

（4）介绍F合和a的瞬时对应关系

a：只有物体受到力的作用，物体才具有加速度。

b：力恒定不变，加速度也恒定不变。

c：力随着时间改变，加速度也随着时间改变。

d：力停止作用，加速度也随即消失。

4：例题分析（课本例题）

（1）学生阅读例题内容

（2）分析：

质量m已知必须先求F1和F2的合力，而合力的大小可

要求物体的加速度以用作图法求解，也可以用计算法求解。

（3）用投影片展示解题过程：

如图所示，建立平面直角坐标系，把力F1和F2分别沿x轴和y轴的方向分解F1的两个分力为：

F1xF1xcos60o,F2yF2sin60o

F2的两个分力为：F2xoF2cos60o,F2yF2sin60

F1y和F2y大小相等，方向相反，相互抵消，F1x和F2x的方向相同，所以：

F合F1xF2xF1cos60oF2cos60o5N5N10N

已知合力F合和质量m，据F合＝ma，即可求得：

10NaF合5m/s2

2kg

三：小结

1：本节课的研究方法——控制变量法

2：牛顿第二运动定律确定了a和F之间的大小关系，也确定的a和F的方向关系

3：求解合力时，可采用建立平面直角坐标系，将各个力沿x轴和y轴分解，最后求合力的方法。

Through learning this passage, we have got to know that English is becoming more and more popular all over the world now.So English learning seems important to everyone, especially us students of the new century.With China’s entry into WTO, English will play a more important part in business, in tourism, and even in people’s daily life.So it’s no doubt that everyone should have a good knowledge of English.And I hope everyone in our class can make an effort to learn English well.But on the other hand, it doesn’t mean English is better than Chinese.We must keep it in mind that one’s mother tongue is the most beautiful language in the world.The reason why we learn English is that we should thus be more capable of building up our country.(六)给学生讲解本课的生词。1.include v.a)contain

1、课后熟读课文；

2、完成Post-reading Ex.2。

课后反思：本课是阅读课。英语阅读教学是高中教学的重中之重。许多英语教师对阅读训练 也给予了足够的重视，但是在训练方式上却存在较多的问题。多数教师过分注重语法结构的 分析和句子的机械翻译而忽视技巧培养。只有在阅读教学中教给学生一些学习策略，培养阅 读技巧，才能让学生有可能通过课外自学来扩大知识的摄取量，从而弥补课堂英语阅读教学 的不足。由于时间仓促以及学生口语水平的局限，本课时在学生让学生讨论的环节上，气氛 不够热烈，讨论时间不足，今后应尽量鼓励学生多开口说英语，以弥补这方面的缺陷。
