18、What is a language for? Some people seem to think it's r practicing grammar rules and learning words．That's wrong．A language is for exchanging ideas．It's no good knowing all about language if you can't use it．

Many students I have been teaching know hundreds of grammar rules，but they can't speak correctly or freely．They are afraid of making mistakes．One shouldn't be afraid of making mistakes．We native speakers make mistakes，too．And we break rules．Bernard Shaw once said，“Foreigners often speak English too correctly．”But the mistakes that native speakers make are different from those that Chinese students make．They are English mistakes in the English language．And if enough native speakers break a rule，it is no longer a rule。What used to be wrong becomes right．The people not only make history，they also make a language．They can make their own language．They can't make another people's language．

So Chinese students who ale learning English should pay attention to the grammar，but they shouldn't overdo it，They should put communication（交际）first．

17、I have been trying to get sick．I don't wear a sweater when I should，and two days ago I walked in the rain without my boots and my feet got wet．But so far nothing has happened．Debbie once told me about a girl who liked to stay overnight in the infirmary（医务室）．She used to rub（摩擦）the end of the clinical thermometer（体温计）until it went up to 102．Then she'd stick it in her mouth and the nurse there would think she was really sick．

This morning I tried doing that but it never went above 94 and I rubbed it for ten whole minutes．So I held the tip（未端）of the thermometer next to the light bulb（灯泡）in my desk lamp and it went up to105．I thought I'd put it in my mouth and walk downstairs like that．Then my mother would take it out and she would be surprised when she saw what a high fever I had!

The only trouble was I didn't know the thermometer would be so hot．As soon as I put it into my mouth, I burned my tongue．Something terrible! I spit the thermometer out．It fell on the floor but it didn't break．I will have to think up a better way to get mother and father back together．I can't waste my time trying to get sick．

16、How to talk to a foreigner? Students often want to practice their English outside class．One of the best ways to practice your English is to speak to a foreigner．This week's question comes from a student who is eager to start a conversation with the foreigners he sees every day．He asks, “Is it okay to talk to foreigners I see in the street? The answer is yes and no, but probably no．If you see a foreigner who looks lost，it is polite to ask him。”May I help you? But，otherwise（除此之外），you should probably let him get on with his business．Situations，however, do exist where it is quite all right to talk to foreigners．If a foreigner enters year school，classroom，office，shop or restaurant，for instance，feel free to ask them  （for example）：

--May I know your name，please?

--Where do you come from?

--What do you think of Beijing?

--How long will you stay in Beijing?

There are also situations where it's okay to talk to foreigners in public places．If you see a foreigner alone in a restaurant，bar or care, it may be appropriate（恰当的）to ask him or her：

--Is this seat free?

--Do you mind if I talk to you in English?

--You pan probably help them if they are new to China and if they are alone，you may be able to make them feel more welcome．After a few such questions, you should know whether this person wants to talk to you or not．If they ask you similar questions, or if they give long, informative（提供有用信息的）answers, you're in luck．If not，then give them their privacy（独处）．Talking to strangers is fun if you choose the right time and place．

14、Can you remember the day when you spoke your first word? If you can, you are unusual．

Try to imagine what first few months of your life were like．I am sure you just spent most of your time eating，sleeping and crying．As you grew older，you were awake more of the time。It took your parents more time to play with you and talk to you．You watched and listened curiously（好奇地）．You began to know that people made certain sounds to go with certain things．

Then you began to try making the sounds you heard。And step by step you were able to make the right sound for one thing．On that day you came to understand the secret of language．The secret is that a certain sound means a certain thing．One sound might be as good as another．But it is no good as a word unless everybody agrees on its meaning．Only when a group of people use the same set of sounds of things，can they understand each other．Then, and only then do these people have a language．

After you found the secret of 1anguage．you learned words．Some of the words meant things，such as books，chairs and shoes．Some words meant doing things，such as “go” and “swim”．And other words describe things such as “good” and “dirty”．Soon you learned to put words together to express your idea，such as “I want to go out and play with my friends．”This is language．By means of（借助于）language people can communicate．

13、Life in modern cities become busier．Some people think we can't raise pets such as cats or dogs．We should spend our time on other things such as work．In my opinion，l think raising pets can relieve（减轻）our burden（压力）of life．

Pets such as cats and dogs can bring us pleasure when we feel lonely and need a company.

Pets can entertain（使快乐）us．Maybe some people think we have no time to raise pets．But raising pets doesn't need a lot of time if we're not too lazy．In fact, raising pets isn't complicated（复杂的）．What we have to do to raise them is washing them，taking food to them and so on，Even if they have no use for anything，they'll not take you much time or energy．

In a word，pets will become our friends，we shouldn't be afraid of spending much time raising them．If you try to raise them．you'll find the interest in busy life．

1、How is life in modern cities?

2、Why should we raise pets?

3、When do we need a company?

4、What do we have to do to raise pets?

5、Is raising pets complicated?
