We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant (持續(xù)的）darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense(感覺) time does not depend on information from the outside world. It is inside them: a kind of "inner (內(nèi)部的）clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control（控制）the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, itaffectssuch things in our life as our need for sleep or need for food.
【小題1】Before the experiment arrived at a conclusion, people had thought that the flowers would____.
| A．never open in constant darkness |
| B．change their usual time to open |
| C．open ahead of the time as they usually did |
| D．continue to open at usual time |
| A．its age and size |

| B．We'll be able to sleep as long as we wish to. |
| C．We'll be able to change our work time when necessary. |
| D．We'll have more energy to do our work better. |
| A．產(chǎn)生 | B．影響 | C．給予 | D．依賴 |

More than 10 years ago, it was difficult to buy a tasty pineapple (菠蘿). The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1966, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition (營養(yǎng)) it was all good news too. This nice tasting pineapple contained four times more vitamin C(維生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out the market.
60. We learn from the text that the new type at pineapple is __________.
A. green outside and sweet inside B. good-looking outside and soft inside
C. yellowy-gold outside and hard inside D. a little soft outside and sweet inside
61. Why was the new type of pineapple selling well?
A. It was rich in nutrition and tasted nice. B. It was less sweet and good for health.
C. It was developed by Del Monte. D. It was used as medicine.
62. The underlined word “fixture” in Paragraph 3 probably refers to something _________.
A. that people enjoy eating B. that is always present
C. that is difficult to get D. that people use as a gift
63. We learn from the last paragraph that Del Monte _________.
A. slowed other companies to develop pineapples
B. succeeded in keeping the pineapple for itself
C. tried hard to control the pineapple market
D. planned to help the other companies
