本课简介
本课主要介绍了由古至今人们对饮食的看法。远古时候，人们认为吃什么补什么。文明社会的人们则一度认为人参的根，鸡蛋，西红柿有各 自不同的神奇功用。今天，人们认为鱼有强身，健脑，壮骨，美肤等作用，还认为饮食方面有诸多禁忌。如此种种的说法是否有道理，本课课文会给你一个答案。
本课主要语言点
1.Many primitive people believed that by eating an animal they could get some of the good qualities of that animal for themselves.
本句中that 引导的是一个宾语从句。宾语从句在前几个单元中我们已有了比较多的了解。掌握宾语从句并不困难。请看下面的句子：
1)You must remember that it is never too old to learn.(你必须记住：活到老学到老。)
2)He says that friendship is very important to him.(他说友谊对他很重要。)
3)Don't forget what your parents said to you.(别忘了父母对你说过的话。)
4)Can you tell me where the bookstore is?(你能告诉我书店在哪儿吗?)
5)I don't know whether the letter is overweight.(我不知道这封信是否超重。)
by 后面跟动词的现在分词表示某人做了某件事，并通过这件事产生了某个结果。请看下面的句子：
1)By bribing a nurse I was able to see some files.(通过贿赂护士我才有可能看到一些卷宗。)
2)They made a living by selling newspapers.(他们通过卖报谋生。)
3)He tried to solve his problem by cheating me.(他通过骗我来解决自己的问题。)
4)We learn to swim by swimming.(我们在游泳中学会游泳。)
2.They thought that eating deer would make them run as fast as the deer.
本句中that同样是引导一个宾语从句。在宾语从句中，动名词短语eating deer做主语。请看下面的句子：
1)Chatting on the internet would make him forget everything.(在网上聊天会使他忘记一切。)
2)Putting on air wouldn't do you any good.(摆架子不会对你有什么好处。)
3)Making friends with them is no easy job.(跟他们交朋友不是一件容易的事。)
make sb. do sth.意思是“使某人做某事”。make 后面的复合宾语中动词不定式符号to要省去，但是用被动语态时一定要用to，请看下面的句子：
1)The boss made them work from morning till night.(老板使他们从早到晚地干活。)
2)He made me sit here all the time.(他让我一直坐在这儿。)
3)She was made to finish the book in two days (by her father)。(父亲让她两天把书看完。)
4)I was made to return the money as soon as possible (by my friend)。 (朋友让我尽快还钱。)
3.Some savage tribes believed that eating enemies that had shown bravery in battle would make them brave.
本句中的第一个that 引导的又是一个宾语从句，而后一个that 引导的是定语从句，修饰enemies.请看下面的句子：
1)He is a man that you can rely on.(他是一个你可以依靠的人。)
2)She gave me some books that I am really interested in.(她给了我一些我很感兴趣的书。)
3)I would never forget the two years that I spent in that village.(我永远也不会忘记我在那个村子里度过的两年时光。)
本句中them brave 是make 的复合宾语，请看下面的句子：
1)Don't wait for him. He will make us late.(别等他了，他会使我们迟到的。)
2)He was afraid that the story would make things worse.(他担心那个故事会使事情更糟。)
3)I didn't know that the news had been made public.(我不知道这个消息已经公开了。)
4.It was once thought …
Eggs were thought to make the voice pretty.
Tomatoes were believed to have magical powers
They were called love apples and were supposed to make people who ate them fall in love.
上面的这些句子全部用的是被动语态。请翻译下面的句子：
1)孩子们受到很好的照顾。(The children are well taken care of.)
2)这个问题最近被谈论得很多。(This question has been much talked about recently.)
3)体育代表团在机场受到了热烈欢迎。(The sports delegation was given a warm welcome at the airport.)
4)那里讲什么语言?(What language is spoken there?)
5)这本书是为儿童写的。(This book is written form children.)
6)他被认为是这个工作的最佳人选。(He is thought to be the best candidate for the job.)
suppose 是一个常用词，请注意掌握。
1)I suppose it was reasonable for him to want his money back.(我看他想要回他的钱是合理的。)
2)I suppose the answer is that he was not so hardworking.(我想答案在于他不够刻苦。)
3)The situation was even worse than was supposed.(形势比料想的更糟糕。)
4)Who do you suppose is the right person for the job?(你认为谁是这个工作的合适人选?)
5)I am not supposed to talk to you about this.(我不能和你谈这个。)
6)He was supposed to leave for Shanghai last night.(他应该昨夜动身去上海。)
7)Suppose / Supposing something should go wrong， what would you do?(如果有了什么差错，你怎么办?)
5.How surprised the people who thought tomatoes poisonous would be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during WWII.
“how surprised the people would be”是主句，这是一个感叹句;who 引导的定语从句修饰people;if 引导的是条件状语从句。
感叹句通常用what 或how 引起。what 用来修饰一个名词，how 修饰一个形容词，副词或动词。请看下面的句子：
1)What a kind-hearted man he is!(他是一个多么好心的人啊!)
2)What good news it is!(多好的消息啊!)
3)What a beautiful city!(多美的城市啊!)
4)How lovely the children are!(多可爱的孩子啊!)
5)How well she writes.(她写得多好啊!)
6)How I hated all this.(我多恨这一切啊!)
6.One such idea is that fish is the best brain food.
