DOn May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadnt 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(节奏). 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 tell her the time. Shed had no clocks 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 hadnt 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 171bs in weight as a results! She had also become rather depressed（抑郁）.How had she spent her time in the cave? As part of the experiment shed done some physical and mental tests. Shed 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, shed played cards, read books and listened to music. Shed 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 dont start to wake up till 9:00 or 10:00 am. This affects the whole daily rhythm. As a result, the early risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!第68题：Stefania stayed in the cave for a long time because ______.A. she was asked to do research on miceB. she wanted to experience lonelinessC. she was the subject of a studyD. she needed to record her life

The willful blindness in hockey toward concussions (头部撞击) has dropped. Hockey Canada has followed the lead of USA Hockey in preventing body checking (身体拦截) below age 13.(41) __________ This country's children have been facing similar danger at early ages, and Hockey had to deal with a deep worry in the winds of Canadians to make the rule change. The liking for body checking from an early age is part of what makes Canadian hockey what it is.The change in rules should be taken as a chance to draw special attention to skill development in an environment free of danger. (42)__________For years, many Canadian hockey parents and coaches have insisted that body checking at early ages is necessary to ensure that players can do it safely at older ages. (43)__________ When USA Hockey changed its rules for the 2011-2012 season, it also created bodychecking-education programs that will be mandatory (强制的) for all coaches, including those teaching players in the pre-checking ages. And it began to encourage more"touch", without real body checking from 9 to12. It also made the rules for 13 and up stricter. (44) __________Hockey Canada has taken serious steps to do away with hits on the head. (45) __________Too often, body checking has been used to try to separate a player from his head rather than from the ball. Children were paying a price for this country's love of the game.There are always changes in Canada's game, and the change in the body checking age sends the clearest message yet to coaches and parents that player safety is paramount (至上的) in the game.A.True or not, there may be a safer way to teach hitting than to make younger players pay a price for it in head injuries.B.However, it's hard to change a sports culture so connected with who we are as a country.C.A bad head injury of Sidney Crosby, the hockey's greatest star, opened the eyes of hockey people everywhere.D.It may also control the loss of thousands of young players who don’t enjoy that environment.E.The USA is trying to show that it's possible to teach hockey protective skills without putting 11 and 12-year-olds in greater danger. It's worth the try.
