教材分析

The emphasis of this period will be placed on the important new words, expressions and sentence patterns in the parts Warming up, Pre-reading, Reading and Comprehending. In order to make students understand these important points thoroughly, we can first get students to understand their meanings in the context, then give some explanations about them, and later offer some exercises to make students master their usages. Some words and expressions, such as in common, begin as, be built as, etc. are very useful and important. So are the sentence patterns “As time went by, I was made smaller.”

“And my memory became so large that even I couldn’t believe it.”

, and so on. We ought to pay more attention to them and design special exercises. At the end of the class, the teacher can make students do more exercises for consolidation. By doing so, they can learn, grasp and use these important language points well. 三维目标

do with的do是及物动词中，表示如何“处置”，常与what连用，what是do的宾语；而deal with中的deal是不及物动词，表示如何应付或安排什么，常用how，how是deal with的状语。

Step 5 Sentence focus 1、I began as a calculating machine in France in 1642. 1642年我在法国诞生时是一台计算机器。

这是一个简单句，句中的calculating 是动名词作定语的用法，动名词作定语一般表示用途，例如：a walking stick拐杖，a swimming pool游泳池，a mashing machine洗衣机。注意和现在分词作定语的不同，现在分词作定语往往表示动作或特征，例如：a sleeping

boy一个正在睡觉的男孩，exciting news令人激动的消息。

2、In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a “universal machine” to solve any difficult mathematical problem. 在1936年，我真正的父亲艾伦•图灵写了一本书，讲述了怎样能使我成为一台“通用机器”来解决任何数学难题。

这是一个比较长的复合句，句中的how

I could be made to work as a “universal machine” to solve any difficult mathematical problem是介词about 的宾语。

3、However, this reality also worried my designers. 然而，这个现实也令我的设计者们犯愁。

However的用法：

However adv.

可是；然而

We have not yet won; hoever, we shall try again.我们还没有取胜，不过我们还要再试一下。

He hasn’t arrived. He may, however, come later. 他还未到。不过，他可能过一会儿来。

I’d like to go with you; however, my hands are full.我很想和你一块儿去，可是我忙不过来。

注意：however除用作副词外，还可用作连词，表示“不论；不管”，相当于no matter how,引导让步状语从句。例如：

He can answer the question however hard it is.不管问题有多难他都能回答。

However sly a fox may be, it is no match for a good hunter.狐狸再狡猾也敌不过好猎手。

比较however, but However和but是词义很近的同义词，都表示转折或让步。

But用来引出微弱的相反的意见，是口语常用词，所引导的部分只能放在另一分句的后面。例如：

It’s a pleasant dream but everything depends on “if”.

这倒是个非常令人愉快的梦想，但一切都取决于“如果”。

However比but的词义还要弱，并不直接引出相反的意见，常用作插入语，它可以放在句首、句中或句末。例如：

You will be lucky if he lets you go without a ticket. However, this does not always happen. The most surprising thing about the plane, however, is that it can land anywhere. 4、As time went by, I was made smaller. 随着岁月的流逝，我被做得越来越小。

这是一个复合句。as time went by是时间状语从句，主句的谓语动词形式是一般过去时

的被动语态。短语go by在这里的意思是“过去”，指时间等的流逝；smaller为形容词的比较级，表示“更小”。

5、Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! 随着时间的推移，我的记忆能力发展得如此之快，就像一头大象一样，我从来不会忘记告诉我的任何事情！

在英语中用动物作比喻的例子很多。句中的like an elephant，这个比喻来自英语谚语“An elephant never forgets.”大象永远不会遗忘。
