Now and again I have had horrible dreams, but not enough of them to make me lose my delight in dreams. To begin with. I like the idea of dreaming, of going to bed and lying still and then, by some queer magic, wandering into another kind of existence. As a child, I could never understand why grown-ups took dreaming so calmly when they could make such a fuss about any holiday, this still puzzles me. I am puzzled by people who say they never dream and appear to have no interest in the subject. It is much more astonishing than it would be if they said they never went out for a walk. Most people do not seem to accept dreaming as part of their lives. They appear to see it as an irritating little habit, like sneezing or yawning I can never understand this. My dream life does not seem as important as my waking life because there is far less of it, but to me it is important.

Korean tradition

　　On May 14 in Seoul about 200 South Koreans and foreigners took part in the annual “Gwageo”．They took the “state examination” sitting on straw matting in the historical Sungkyunkwan building．　　1　　

　　Unlike the examinees tested hundreds of years ago, their subjects include English alongside the expected Confucianism and Chinese．　　　2　　

　　The Gwageo examination first took place in 958 AD．　　3　　 It was abolished after 1894 because of the Japanese occupation．Last year, the Sungkyunkwan University restored the Gwageo tradition in order to promote traditional Korean culture．　　4　　

　　Established in the late 1.300s, the old Sungkyunkwan has been the centre of Korean study for more than 600 years．　　5　　

A．In the past it was the place where people went to study Chinese and Confucianism．In 1948 Sungkyunkwan University added modern life to the old Confucian study centre．

B．They also had to wear traditional Korean costumes．

C．Although the exam is not for selecting officials, it’s not just for show either．The Gwageo is now part of the university’s finals．

D．We will go to South Korea for the exam next year．

F．It was used to select national government officials who studied Confucian classics in Korea．

E．More students are accepted in South Korea than in China．

G．They have to complete their exams on computers instead of writing on paper with brushes and ink-stones．

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
A. what stem cells were                     B. whether they would grow back
C. how long it would take to re-grow    D. how they would re-grow
41. A newt will re-grow its leg if _____.
A. its ankle was cut off but the nerve bundle was good
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle were cut off
42. What do the underlined words “these materials” refer to?
A. Nerve bundles and proteins.         B. Proteins similar to n-AG.
C. Stem cells and proteins.               D. Stem cells and nerve bundles.
43. The first sentence of the passage _____.
A. acts as a lead–in                       B. shows where researchers got their new ideas
C. states the author’s opinion           D. describes the result of researchers’ studies
