Some experts were saying that the unexpectedly low number of human genes would be good for medicine, since there are fewer genes to understand. But it could work equally well in the opposite direction: the complex interactions between genes may make it harder to cure disease by changing one or two of them, for example through gene therapy. This may explain partly why gene therapy has given disappointing results in clinical trials over the past ten years. The emerging technology of stem cells replacing failing cells with potent new cells may produce better results because the patient is receiving the whole genetic system at once.

Books even in this age of cheap literature cost money? The shortage of paper, together with the high cost of living, has made book an expensive item in our list of requirements. This would mean that fewer people can afford to have them. Yet there are people who think nothing of spending money on a rich dinner, but would consider it a waste of money to spend the same sum on books. Therefore the time has come for an adventurous public library policy to be introduced, for the higher the price of books, the greater the need to give them the widest circulation possible.

The Government of the Hong Kong Special Administrative Region has set up Urban Council Libraries and study rooms in various districts. There is no doubt that Libraries are a great

blessing, and when books are wisely selected, they have a great educational value, and have done much to encourage the habit of reading among the people.

For setting up libraries, some factors should be taken into consideration. In the first place, it is not enough to have just a building, equip it with shelves and fill them with books. The library building itself must be attractive in structure, conducive in atmosphere and unencumbered in administration. Then secondly, there is the choice of suitable books

to look into. This presents difficulties: though most of the books are novels and most of the readers are novel readers, moreover, reading fiction is quite a source of amusement and pleasure, also, it is a means of broadening one's mind and learning more about life and human being, yet, there should always be a good selection of serious books - history, biography, travel, poetry and literature - which are appreciated by many readers. Young readers are naturally interested in books which cater to their personal preferences.

In those countries (for instance, Singapore where several different races share equal weight, there are not only the above problems in hand when setting up libraries. There is a third issue - readers with different family and racial backgrounds have different preferences. The problem seems soluble if they can provide the readers with books written against familiar background and in their own language.

26.The writer's opinion in the first paragraph is that __________. A.books are less expensive than they used to be B.rich people are not fond of reading

C.the high price of books has made their circulation impossible D.a public library policy is beneficial to both the rich and the poor 请根据需要填入Script: 正确答案:C

27.The difficulty in setting up a library according to this passage is __________. A.the shortage of paper B.selecting suitable books C.the high price of books
