Book 2 Unit 3

Learning about language 计划课时:2个课时

一、

内容及其解析

这节课主要学习的内容是词汇。这部分练习和阅读部分是紧密相连的，作练习1，可以让学生课后独立完成。并要求学生小组长监督检查，答案确定后，为了加深学生的印象，请学生再检查一次。练习2是为了检查学生对本单元的黑体部分词汇、短语的掌握情况。可以让学生分组讨论。老师还是可以指导部分后进生完成此习题. 二、教学目标及其解析

检查、督促学生对所学词汇能否在不同语境中的灵活运用能力，帮助学生增加词汇量，提高学生问题引领教学与利用工具书解决问题的能力。

三、问题诊断分析

部分学生对词汇构成、构词法掌握不好，理解、运用所学习的词汇在不同的语境中的灵活运用能力较差，也不会利用上下文进行恰当推测文章意思。同时，部分学生自觉学习的习惯不好，能力不强等等。

四、教学支持条件

多媒体，学案集，粉笔，黑板

1. Although I was young I could simplify difficult sums. 尽管我很年轻，但我能简化一些复杂的数学题。

▲本句为although引导的让步状语从句，相当于though。Although 和though不能与but， however，still等表示转折含义的词汇连用。

▲simplify vt . 简化；使简易

Eg：The English in this story has been simplified to make it easily understood. 这个故事里的英语被简化了，可以更容易理解。

联想：simple adj. 简单的 simplicity n. 简单simplified adj. 简化的

simplification n. 简化；简易性simply adv.简单地；仅仅；简直

▲句法分析：本句为before引导的时间状语从句，此处意为“过……之后才……”

Eg: I had walked five kilometers before I realized I had left my key in the office. 拓展：

（1）尚未…..之时

Eg; Someone knocked at the door he left before I could answer it. 有人敲门，但没等我去开他就走了。

technology n. 工艺；科技；技术

technique n. 技巧；技艺

technical adj. 技术的；技能的；工艺的；技术性的；

technically adv. 在专业上；在技术上；在工艺上

technician n. 技师；技术员

误区点拨：technology 与 technique ( 1 )technology意为“技术”“工艺”，是学术理论上的总称。Eg: science and technology. ( 2 )technique 常指某种具体的技术、技艺。Eg：the technique of drawing. 变式练习：

(1). She’s a wonderful artist, who combines different in the same painting. (2). As a musician, she is quite accomplished. (3). Nowadays science and are developing rapidly. (4). Recently they have made a major

Eg：With a lot of problems to solve, he leads a hard life. 有许多问题要解决，他的日子不好过。

With the help of his friends, he finally solved the problem. 在朋友的帮助下，他终于解决了这个问题。

联想：solution n. 解决办法；处理手段

a solution to sth. ……的解决办法

误区点拨：settle 与 solve 二者都有“解决”的意思，但settle得解决对象是某种形式的争端，solve的解决对象往往是一个需要给出答案的问题。

Eg：settle an issue / argument settle a quarrel / matter Solve a problem / mystery / puzzle

settle difficulties 变式练习：

(1) With all the problems

at the meeting, the newly-elected manager felt rather relaxed. A. to be solved B. solved C. solving D. having

solved (2)He was very bright and

the crossword in ten minutes. A. solution B. solved C. settled D. ended 5. From then on, I grew rapidly both in size and in brainpower. 从那以后，我在体积上和脑力上快速成长。

(1)事实上，他没有通过驾照考试。

，he didn’t pass the driving test. 7. As time went by, I was made smaller. 随着时间的推移，我被做得更小了。

▲句法分析：句中as为连词，引导时间状语从句，意为“随着”。

Eg: As spring draws near, it’s becoming warmer and warmer.

随着春天的来临，天气越来越暖和。

友情提示：with也可意为“随着”，但它是介词，不能引导从句，

如：As the years have gone by……; 如用with, 应为：with the years passed……。

▲go by （时间等的）流逝；经过；（机会等）轻易地放过。

Eg：The weeks went slowly by. 时间一周周慢慢地过去了。

She waved as the bus went by. 汽车经过时她挥了挥手。

昨天雨下得很大。因此，相当多的学生迟到了。

拓展：as a result of 由于……的结果 result in导致……，相

当于lead to Result from 由……导致

误区点拨：as a result 与 as a result of (1)as a result表示“作为结果，因此”。

(2)as a result of表示“作为…….的结果，由于”。

Eg: The conditions were poor; as a result, a sit-down strike began. =A sit-down strike began as a result of the poor conditions. 由于条件太差，结果发生了静坐罢工。

变式练习：

They are playing so skillfully that I’m afraid we’ll love the game. 他们打得这么熟练，因此我们担心我们得输了。

拓展：so + many / much / few / little + 名词 + that So + adj. + a / an + 可数名词单数 + that As + adj. + a / an + 可数名词单数 + as How + adj. + a / an + 可数名词单数

Too + adj. + a / an + 可数名词单数 + to 误区点拨： so……that 与 so that (1)so that既可表结果，也可表目的。

Eg：I hired a boat so that I could go fishing. 我租了一条船，为的是可以去钓鱼。

The driver let us get off the broken bus so that we walked there. 司机让我们下了那辆抛锚了得公共汽车，我们只好步行到那里。

(2)so……that….结构中that引导结果状语从句。

Eg：He got up so late that he couldn’t catch the early train.他起晚了以至于没赶上早班火车。

So hard does he work that he seldom goes home.他工作那么努力，几乎不回家。

友情提示：

(1)so……that……结构中得so的不能换成as; that有时不能省略。

(2)so后加形容词修饰单数名词时，注意冠词的位置。

(3)such……that……结构中的that也可引导结果状语从句，such只能修饰名词。

(4)such……as……结构中的as引导的是一个定语从句。

(5)so, such修饰的成分置于句首时，主句应用部分倒装结构。

Eg: So difficult a question / Such a difficult question did the teacher give us that no one could work it out. 老师给我们出了一个如此难的问题，谁也没有解答出来。

变式练习：

用so或such填空：

(1)He runs fast that I can’t keep up with him. (2)It was a fine day that they all went swimming. (3)He received little education that he couldn’t do the job. (4)Tom is polite a boy that he cannot leave without a word. (5)It was dark that I could hardly see anything. 10.

联想：explorer n. 探险者；勘探者；考察者

变式练习：

用explore的正确形式填空：

(1)As soon as we arrived on the island, we were eager to . (2)His dream of becoming an has come true. (3)Human beings will never stop the of space. 六、课堂小结

B组：（完成阅读理解）

As a computer exhibition Bill gates reportedly compared the computer industry with the auto industry and stated: “If GM had kept up with technology like computer industry has, we would all be driving twenty-five dollar cars that got 1000 miles to the gallon.”

In response to Bill’s comments, General Motors announced a news release stating: if GM had developed technology like Microsoft, we would be driving cars with the following characteristics: 1. For no reason your car would crash twice a day. 2. Every time they repaired the lines on the road you would have to buy a new car. 3. Sometimes your car would die on the free way for no reason and you would just accept this, restart and drive on. 4. Only one person at a time could use the car, unless you bought “Car95” or Car

If you try to get your car to a mechanic, you’d make a long distance call, be put on hold for three or four hours, when you finally got the mechanic, you’d be told how to fix it yourself, and mechanic would hang up before you even tried his or her suggestions. 6. People would get excited about the “ new” features in Microsoft cars, forgetting completely they had been available in other cars for many years. 7. The airbag system would say: “Are you sure?” before going off. 8.

九、教学反思 本次课设计2个小时完成，但教学中还是遇到较大的问题：一是学生没有预习习惯，课堂上阅读理解句子还需要给他们一些时间，导致占用时间较多；二是学生词汇量少，理解句子的能力较差，导致学生理解句子的速度太慢，没有按计划时间内达成目标。

原因主要还是要先从教师身上找，把学生的学习能力和阅读速度想得太好，设计量太大；另外，教学中没有掌握好学生自主学习和小组讨论的时间控制，学生自主学习积极性没有得到充分发挥。
