Rats eat our food or make it so dirty that it isn't fit for people at all. That's why people often kill them by laying down poison. After a day or two, they find the poison still there. The rats haven't touched it, even though it is near the food which they eat. People think they must be clever and cunning. Some scientists have been trying to find the best way to poison rats. They have watched to see just what a rat does day and night. They have found out that rats aren't so clever. They are just very shy.

　　Rats usually live in holes. They run from these holes to the places where they eat and drink. They have special paths on which they travel each time. So they know their paths quite well.

　　If anything new, such as stone or wood, is put in the path, the rats won't go near it at first as they are too frightened. It will take them many days to get over the fear. They are also frightened to go near a place that they know, where something has been taken away. If a path goes around a rock, the rats follow the same path around the rock each time. If the rock is taken away, they will still run round the place where the rock was! They won't cross the empty place, which is now open to them, even though it would be quicker.

　　Rats will always keep away from anything unusual to them. That's why they won't eat poison on the first or second night. They usually won't go anywhere near it for about four days until they get used to being there. Even then they only eat a little at a time.

　　If people want to kill rats with poison, all they have to do is to leave it out for a few days. Once the rats have got used to it, they will eat it and die.

Professor Martin's report says that children who attend a number of different schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally affected.

　　The professor says, "It's true, my personal feeling is that children should stay in one school. However, our findings are based on research and not on any personal feelings that I or my assistants may have on the subject."

　　Captain Thomas James, an Army lecturer for the past 20 years and him self a father of two, said," I've never heard such rubbish. Taking me for ex ample, no harm is done to the education of my children who change schools regularly－if they keep to the same system, as in our army schools. In my experience, I've known quite a few of them－Army children are as well－adjusted（调整）as any others, if not more so. What the professor doesn't appear to appreciate is the fact that in such situations children will adapt（适应）much better than grown-ups."

　　When this was put to Professor Martin, he said that at no time had his team suggested that all such children were backward or mentally affected in some way, but simply that in their experience there was a clear tendency（倾向）.

　　"Our findings show that while the very bright child can deal with regular changes without harming his or her general progress in studies, the majority of children suffer from constantly having to enter a new learning situation."

　　　　A. is the opposite of what his report has shown

No country in the world has more daily newspapers than the USA.　There are almost 2000 of them，as compared with 180 in Japan，164 in Argentina and 111 in Britain.　The quality（质量） of some American papers is quite high and their views are used all over the world.　Excellent newspapers like the Washington Post or the New York Times　have a powerful influence（影响） all over　the country.　However，the Post　and the New York Times　are not national newspapers in the sense that The Times is in Britain of Le Monde is in France，since each American city has its own daily newspaper.　The best of these give detailed（详细的）accounts of national and international news，but many tend to limit themselves to state or city news.?

As in other countries American newspapers can be either responsible（负责任的） or irresponsible，but it is generally accepted that the American press serves its country well and that it has more than once exposed political scandals（丑闻），for example，the Watergate Affair（水门事件）.?
