When the musical sound rings you, you immediately reach for your pocket ready to have a chat. But although you probably use it all the time, have you ever stopped to think about the manners related to talking on the phone? If you haven’t, here are some tips to guide you.

●Always give the person you are calling plenty of time to get to the phone before you hang up. If the person who answers is not the one you want,give your name and ask if you may speak to the person you want.

●Think about the time you call people. Try not to call too early in the morning(before about 9:00)or too late at night(after about 9:30). Also try not to call at mealtimes.

●If you go by plane to visit your relatives at Christmas, remember to follow airline instructions. Cell phones must be turned off as soon as the plane doors are closed and remain so until the doors open again on arrival.

●When face to face with someone, do not talk on the phone. It is rude to be on the phone when a waiter is trying to take your order in a restaurant, or when you are returning the shoes you have just been trying on in a shop. Finish any face-to-face business before taking a call. Continuing to use the phone while nodding to the person in front of you is quite impolite.

●When in a restaurant with your friends,keep phone conversations short. Make a call only if it is important. Practise speaking in a low voice. If no one looks your way, you’ve got it.

●If you go to a theatre, a concert or a cinema, consider the other people around you. Check that your phone is “off” before you enter. If you are expecting a very important call, put your phone on “vibrate”(振动)and run for the exit as soon as you feel it. If you forget both “off” and “vibrate” and your phone rings, don’t answer it, turn it off straight away.

B. You may talk loudly on the phone at dinner in the restaurant.

Many people have described television as a passive activity that is harmful to children’s education. However, there are good and bad ways to watch television. Parents who are interested in exploiting television as a learning tool can actually turn time in front of TV into an educational chance.

Probably the most familiar educational way to use television is to simply watch educational programs. In particular, this means selecting channels and programs specially designed for educational purposes. Along with traditional educational shows for children on public broadcasting channels, cable television (有线电视) now offers kids and adults a wide variety of educational programs, with everything from nature shows to historical events in different countries.

Captioning(字幕),such as "closed captioning" for hearing disabled viewers provides another way for parents to exploit the educational possibilities of television.One study showed that children who watched captioned TV got great improvement in their vocabulary and oral reading ability. In addition, parents can make any show a learning class by watching television together with children. By actively joining children in the programs that they are watching, parents can help with the development of such skills as predicting(预见)and summarizing. In order to develop predicting skills, parents and children could first refer to a program’s description in a viewing guide.After reading the program description and guessing what might happen in the program, parents and children could watch together to see which predictions were correct. And to practice summarizing, after watching a program, parents can turn off the TV and ask what the story was about. This kind of activity helps children develop thinking skills such as arranging events in an order and memorizing information.

Although there will still be plenty of times when children watch TV simply for passive enjoyment, parents can help make at least part of their children’s viewing time a more productive activity.Used intelligently by exploiting the learning chances available through various programs, television can play an instructive role in children’s education.

Which activity is NOT suggested in the passage?

A. Talking about TV shows.     B. Watching captions on TV.

C . Enjoying films about nature.     D. Watching shows for homework.

Which of the following statements is true according to the passage?

A. Parents can simply make any show a learning class for their children.

B. To make watching TV a more productive activity parents should include themselves in the producing process.

C. Most parents have changed their attitude to their kids’ watching TV and become positive to the problem.

D. In a way, it is how parents act that leads to whether watching TV may do good or not to their children.

We can infer from the last paragraph that       .

A. not every minute when a child watches television must be educational

B. children should not use television for passive enjoyment

C. some children prefer reading to watching television

D. television offers more learning chances than school

Which of the following questions is the major one discussed in the passage?

Drinking wine in moderation improves the IQ and may boost mental agility in old people,according to Japanese researchers.

A study of the effects of alcohol on the middle aged and elderly found the average IQ of men who drink wine (whether made from grapes or rice) was 3.3 points higher than that of men who do not imbibe.

Similarly,the IQ of women drinkers showed an improvement of 2.5 points over their teetotal sisters.The findings are part of an ongoing study by Japan’s National Institute for Longevity into the links between human intelligence and what we eat and drink.

The tests measured general knowledge,powers of judgment and concentration in drinkers and non-drinkers over 40,all living in Aichi prefecture,central Japan,and sharing the same income level-roughly£50 000 a year—and educational background.All were university graduates.

But while wine-drinkers appeared to be brighter,the same was not true of those who drank deer,shochu (a local gin) and whisky.

“The benefits of wine and sake (rice wine) in raising IQ could be due to substances they contain,such as polyphenol,which are believed to slow the ageing process,” Hiroshi Shimokata,head of epidemiology research,said.

It was premature to conclude,he added,that drinking wine or sake slowed the deterioration of brain functions in the elderly,or warded off senility.The research does,however,suggest that this is one way to stay mentally alert longer.

But there is a sobering caveat:drinking too much may make you dimmer.“People who drink more than 540 milli-litres (a little over a pint) of sake or wine a day had lower intelligence quotients than those who did not drink at all,”Hiroshi Shimokata said.“Moderation is very important.”

Which one is the topic of the passage?

A.Drinking wine in a large amount improves the IQ of old people.

B.Drinking wine in a reasonable amount raises the IQ of old people.

C.Drinking wine in moderation does good to any one.

D.Drinking wine helps improve the IQ of women.

According to the passage,which of the following is NOT wrong?

A.Every wine drinker’s IQ is 3.3 points higher than that of men who don’t drink.

B.The IQ of women drinker is 2.5 points lower than that of the non-drinking women.

C.Drinking beer and whisky cannot improve one’s IQ.

D.Drinking wine can only do good to the IQ of rich old people.

The reason why wine and sake can improve IQ is that _________.

A.wine and sake have special taste

B.wine and sake can make us excited

C.wine and sake contain substances considered to slow the ageing process

D.wine and sake contain something believed to prevent us from ageing

From the text,it seems that we can conclude _________.

A.the more wine we drink,the brighter we are

B.the less wine we drink,the brighter we are

C.drinking wine less than 540ml a day,we’ll become dimmer

D.drinking wine in moderation,we’ll become brighter

    American cities are similar to other cities around the world: American cities are changing, just as American society is changing. After World War Two, the population of most large American cities decreased; however, the population in many Sun Belt cities increase. Los Angeles and Houston are cities where population shifts (转移) to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents became weathier. They moved out of their apartments in the city to buy their own homes. They bought houses in the suburbs (郊区).

     Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young professionals are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and possiblilies that the city offers.

     This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough meney to move to the suburbs; now many of these same people do not have enough money to stay in the cities.

     Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is sure:many dying cities are alive again.

What does the author think of cities all over the world?

    A. They are alive.                                      B. They are hopeless.  

C. They are similar.                    D. They are different.

Why did American city residents want to live in the suburbs after World War Two?

   A. Because older American cities were dying.

   B. Because they were richer and needed more space.

   C. Because cities contained the worst parts of society.

   D. Because they could hardly afford to live in the city.

According to the 4th paragraph, a great many poor people in American cities             .

   A. are faced with housing problems                     B. are forced to move to the suburbs

   C. want to sell their buildings             D. need more money for daily expenses

   D. the population is decreasing in older American cities
