Article: More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons.Exercise strengthens the heart muscle,reduces blood pressure and help to prevent muscles from changing into fat.Physical exercise is just as important for children. Exercise and food affect growing speed in young lab animals.Baby mice start running as soon as they are big enough to use an exercise wheel in their cage.If they get extra food and run a lot,they will grow as much as 1.5 times bigger than normal. The same differences in growing speed might be found between active and inactive children.Physical exercise helps active children grow faster than inactive children.One experiment shows that the brains of the mice that had enough exercise weighed about 3%more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise. The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected. The good effects of physical exercise are not limited to children and middle-aged people.Exercise continues to be an important part of our lives after we grow old.For example,people over 50 years old begin to lose calcium from their bones,which get weaker and can break easily.Physical exercise,however,helps to strengthen the bones and to prevent them from losing calcium.Of course,old people can take medicines to prevent themselves from suffering from losing calcium.But the medicines they take increase the chance of developing some kind of cancer .So physical exercise is a much safer treatment . Question: From the passage we know that_. - mice need to eat more and exercise more - children need more exercise than other people - old people like to take medicine to treat their illnesses - middle-aged people are easy to get fat
middle-aged people are easy to get fat

Read the following article and select the best answer. Article: The following card includes a brief summary and a short assessment of a research paper. It can provide a guide for further reading on the topic. Trevor, C. O., Lansford, B. and Black, J. W., 2004, "Employee turnover and job performance: monitoring the influences of salary growth and promotion", Journal of Armchair Psychology, vol. 113, no.1, pp. 56-64. In this article Trevor et al. review the influences of pay and job opportunities in respect of job performance, turnover rates and employees' job attitude. The authors use data gained through organizational surveys of blue-chip companies in Vancouver, Canada to try to identify the main cause of employee turnover and whether it is linked to salary growth. Their research focuses on assessing a range of pay structures such as pay for performance and organizational reward plans. The article is useful as Trevor et al. suggest that there are numerous reasons for employee turnover and a variety of differences in employees' job attitude and performance. The main limitation of the article is that the survey sample was restricted to mid-level management, thus the authors indicate that further, more extensive research needs to be undertaken to develop a more in-depth understanding of employee turnover and job performance. As this article was published in a professional journal, the findings can be considered reliable. It will be useful additional information for the research on pay structures. Question: As is mentioned in the card, the limitation of the research paper mainly lies in that _ . - the data analysis is hardly reliable - the research sample is not wide enough - the findings are of no practical value - the research method is out-of-date
the research sample is not wide enough

Q: Read the following article and select the best answer. Article: There have been a number of occasions through the years that I had to sit at the feet of a theologian .Some of those times, I came away wondering what on earth the man was talking about. That was not the case when I heard Dr. Randy Harris. He suggested that a lot of our day-to-day problems in the world be solved by simply keeping our promises. Too many people do not take such matters seriously. Are you serious in keeping your promises? Some of my most anxious moments in over a half-century of ministry have come as a result of carelessness in failing to keep my word. Preachers can say a lot of requests on any given Sunday. I have been asked to make hospital visits, write letters of recommendation , put people's names on the prayer list, read books, make telephone calls, remember birthdays and anniversaries, come to special events, and put announcements in the church bulletin . There was a time when I would foolishly agree to fulfill each request. I had the best of intentions, but I could not remember all I had agreed to do, much less find a way to do them all! Did I think I was "Super-Preacher"? The sad look of disappointed faces taught me that I was not. I hurt people, and they deserved better. The Hebrew word of covenant means primarily "a cutting". It refers to the custom of cutting an animal in half and having the parties making promises pass between the two halves. They were saying to each other, "If I don't keep my word, may I be as this animal--be cut in two." If butchering were the result of breaking our word today, how many of us would be headed for the death? I think that, although we are not cut like animals for our failures to keep promises, there are serious results connected with our carelessness. It ruins our character and our reputation. What can we do? It is simple. Stop making promises we cannot keep. Reduce promise lists, and be sure to carry out the commitments that remain on it. If after giving our word, we are unable to keep the appointment or whatever, inform and apologize as... Question: The author was a bit _ about the new couple's vows. - upset - concerned - sad - uneasy
A: concerned

Read the following article and select the best answer. Article: My father's reaction to the bank building at 43rd Street and Fifth Avenue in New York city was immediate and definite: "You won't catch me putting my money in there!" he declared, "Not in that glass box!" Of course, my father is a gentleman of the old school, a member of the generation to whom a good deal of modern architecture is upsetting, but I am convinced that his negative response was not so much to the architecture as to a violation of his concept of the nature of money. In his generation money was thought of as a real commodity that could be carried, or stolen. Consequently, to attract the custom of a sensible man, a bank had to have heavy walls, barred windows, and bronze doors, to affirm the fact, however untrue, that money would be safe inside. If a building's design made it appear impenetrable , the institution was necessarily reliable, and the meaning of the heavy wall as an architecture symbol reflected people's prevailing attitude toward money. But the attitude toward money has, of course, changed. Excepting pocket money, cash of any kind is now rarely used; money as a has largely been replaced by credit. A deficit economy, accompanied by huge expansion, has led us to think of money as product of the creative imagination. The banker no longer offers us a safe: he offers us a service in which the most valuable element is the creativity for the invention of large numbers. It is in no way surprising, in view of this change in attitude, that we are witnessing the disappearance of the heavy-walled bank. Just as the older bank emphasized its strength, this bank by its architecture boasts of imaginative powers. From this point of view it is hard to say where architecture ends and human assertion begins. Question: 36. The main idea of this passage is that _ . - money is not as valuable as it was in the past - changes have taken place in both the appearance and the concept of banks - the architectural style of the older bank is superior to that of the modern bank - prejudice makes the older generation think that the modern bank is unreliable
(A).
changes have taken place in both the appearance and the concept of banks
