A recent survey in the United States showed that the average family spent more money on its pets than on its children. Although rather shocking, it should not surprise anyone who has seen the doggy parlors(客厅) where loved pets rest. Are Americans unique in treating their little friends in this way? No, the English, too, pay more attention to their pets.
This can clearly be seen when we look at pet foods, which often contain more vitamins than human food. They certainly cost much. Last year the British public spent two hundred million pounds on pet food alone, to say nothing of veterinary bills or animal furniture. It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty, so it is not unusual for me to get hot under collar when I read an old man left all his money to his dog instead of his children.
There are a variety of reasons why I find pets-raising alarming. They cause physical problems. An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets. Many people find this funny, but in a number of large cities it is a major problem. Animals can cause disease, too. It is the threat of rabies — a disease with no known cure.
Another problem is the carelessness of pet owners. Most little children want a dog or a cat, and they continually push their mothers and fathers until they get one. It is only when the "sweet little thing" has been brought home that the parents realize how much time and money must be spent on "Rover" or "Bonzo". Then they just abandon it. As a result, they are allowed to run free. English farmers lose hundreds of sheep a year, killed by someone's pet and you must have read of children being hurt by some pets of their own.
Lastly, I would only suggest that we have got our priorities wrong and that something should be done about it. In my view, it's time we stopped being sentimental about pets. I can see no reason why we should get upset when animals are cut up for medical experiments. This will lead us to discovering cures for serious human diseases, then I say, “keep cutting!”
43. The doggy parlors are mentioned in the 1st paragraph to show ___.
A. where Americans keep their pets
B. what costly lives the pets are living
C. why children love their pets so much
D. how much pets depend on their masters

A. getting quite hot B. feeling overwhelmingly angry
C. becoming excited D. receiving a fashionable shirt
45. According to the author, in which field can animals be most useful?
A.Pet. B. Food. C. Medicine. D. Sports.
46. What is author's attitude towards pets-raising?
A. Pitiful. B. Neutral. C. Opposed. D. Supportive.

Man still has a lot to learn about the most powerful and complex part of his body — the brain.
It may be surprising to learn that it isn't age that makes you lose your memory. The reason could be that you have a "lazy" memory, not an old one. Like your body your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let's look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with the senses (what we see, hear, feel and smell). It's the creative and imaginative side. The left side is concerned with logic. It analyzes information and puts it in order.
Some recent research suggests that we remember everything that happens to us. The problem most of us has is recalling events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on.
This shows revision is very important. If you revise new material you have learnt, you remember much more. So it's of vital importance to revise newly learned material often, and have frequent breaks. We best remember what we learn at the beginning of a learning period and at the point where we stop. After the break, revise what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes.
Other experiments have shown the brain needs time to "digest" what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have absorbed what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks and to revise newly learned material immediately before you begin studying again. If you do in this way, your memory will improve.
