Question

On May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms (節(jié)奏)。In this experiment Stefania had spent 130 days in a cave, 30 feet in depth.

During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to fell her the time. She’d had no clock or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24-hour day. She had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 17lbs in weight as a result! She had also become rather depressed (抑郁).

How had she spent her time in the cave? As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature, For example, the pattern of day and night makes us wake up and go to sleep. However, People are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10;00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!

【解析】

1.細節(jié)理解題。根據(jù)第一段中Stefania was in a research program和整段的意思，可以排除A、B、D項。

2.細節(jié)理解題。根據(jù)第二段中 She hadn't kept to a 24-hour day. She had stayed awake for 20-25 hours and then had slept for 10 hours. 可知答案。

3.推理判斷題。從全文的內(nèi)容來看，本文主要報道了一個實驗及實驗得出的結(jié)果，所以由此判斷本文可能來自于新聞報道，A項小說不可能。因為文章沒有小說的特點；C項不正確，本文沒有涉及寵物問題；D項不正確，因為本文也沒涉及旅游的問題。
