阅读短文，判断正(T)误(F) 。      Do television advertisements make kids eat unhealthy food? Some scientists say "yes". They have  done a study and found that food advertisements change what kids eat. Television advertisements often  encourage kids to eat foods that are bad for them. These foods can make kids become very fat. This is  a growing problem for kids across America.       A report says an American kid sees about 40,000 advertisements a year. That"s almost 110  advertisements a day! They show drinks, cookies, candies and fast food. They often make kids want to  eat more of these unhealthy foods. As a result many kids are overweight.     To attract kids, advertisements sometimes use popular movie or cartoon stars. Many of these  advertisements don"t tell kids what the foods are made of. As a result, many kids may think that the  foods they are eating are good for them.       What should kids do to keep healthy? Scientists say kids should talk with their parents and doctors  to make sure they are eating healthy foods. Doctors also say that exercise is very important. So maybe  overweight kids should watch less TV and do more exercise. 1. Television advertisements change what kids eat. 2. Becoming very fat is good for kids. 3.

Both writers have their own ideas on zoos.                                                                  Zoos Do a Good Job     It is good to keep animals in zoos. I know a lot of people think it is wrong to keep animals in zoos.  However, I believe that zoos have many good points.     Firstly, zoos are places for people to see different animals from all over the world. Without the zoos,  most people would never see a real bear or tiger.        Secondly, zoos look after the animals very well. The animals are always given food and cleaned  regularly (定期的). In the wild, it is not always possible for an animal to find food, so sometimes it goes   hungry. But animals kept in zoos never go hungry.      Thirdly, zoos protect the animals they look after. They offer them safe places to live in. In the wild,  some kinds of animals are in danger of becoming extinct (灭绝的). But zoos give these animals a chance  to live. Without zoos. There would be fewer kinds of animals in the world.                                                                                                                           Maria Smith                                                                       Zoos are Unnatural      In Maria"s letter, she says that zoos are good for animals. I am afraid that zoos are not good for  animals, they are only good for people.       It is unnatural and unfair to keep wild animals in cages. Most animals are kept in cages that are too  small for them. In the wild, these animals would travel freely In zoos. They can"t do this. This is why the  bears and tigers always look so sad.         Most cages are not very clean, either. It is true that zoos give the animals food regularly, but this is  not natural. Wild animals are used to looking for their own food. We should treat animals in the same  way that we treat other people with respect.        Would anyone be happy if you don"t let them go outside his home? Would Maria like to have lots of  people stand out side her flat looking at her? No, she wouldn"t. And animals don"t like it, either.                                                                                                                                 Philip Black 1. Maria and Philip have quite different ideas on keeping animals in zoos. 2. In Maria"s opinion, a real bear or tiger can only be seen in zoos. 3. Maria thinks that animals live better in zoos than in the wild. 4. According to Philip, if cages are big and clean enough, tigers and bears will look happy. 5. Maria and Philip both agree that zoos are good for people.

There are Tibetan antelopes (藏羚羊) , which live on the Qinghai-Tibet plateau (高原) have been used to the high speed trains flying by above them. 　　"The heavy use of the underpasses (铁路下过路口 )shows the animals" migration (迁徙)habits have not been affected by the railway," said Yang Qisen, who has been studying the railway"s impact (影响) on wildlife since it opened five years ago. 　　Yang, who is a researcher with the Institute of Zoology under the   Chinese  Academy of Sciences  (中科院动物研究厅), said a group of 3,000 antelopes live mostly in eastern Qinghai Province. However, every June, some of them migrate to the Kekexili region of western Qinghai and northeastern Tibet to give birth to their young. 　　The animals make their return journey in August, which means they pass under the railway twice a year, he said. 　　For the past five years, between June and September, Yang and his team have stayed near the railway to find out what it had done on local wildlife. They have paid close attention to the migration patterns of the antelopes. 　　In 2004, 96 percent of the migrating antelopes were seen using the underpasses. After 2005, the figure rose to 98 percent, Yang said.
