8．Scientist have manytheories about how the universe came into being．（理論）

解答 答案是theories．考查名詞復(fù)數(shù)．句意是"科學(xué)家有需要關(guān)于宇宙是如何形成的理論．"所以形容詞many后面接名詞theory的復(fù)數(shù)形式theories表示"理論"．故答案是theories．

點(diǎn)評(píng) 本題考查翻譯填空．首先要判斷填寫(xiě)的單詞及固定搭配，然后根據(jù)句意和相關(guān)語(yǔ)法填寫(xiě)正確的答案．

18．More and more parents are worrying about their daughters who have become overweight．Girls who think they aren't popular at school are at higher risk for weight gain，according to a new study．It's long been known that being overweight can lead to social exclusion （排斥） for teens，but researchers at Harvard University discovered：whether a student's opinions of her social position played a role in her weight．
To find out，the researchers measured the body weight of nearly 4，500 girls aged 12 to 18．
Two years later，the researchers found，all of the girls had gained weight-no surprise，since they were all growing．But girls who thought they were less popular at school were at a 70 percent higher risk of gaining extra weight．
The researchers considered something else besides the collected information，including whether a child was overweight at the start of the study，family income，a mother's weight，diet，television viewing habits and some other things that can affect childhood weight gain．But the opinions of girl's popularity are more likely to affect he girls'weight．
Experts suggested that parents concerned about a girl's weight should look not only at eating habits but also at their child's social network，encouraging relationships with friends and joining in group activities．Meanwhile schools should also organize more programs to help girls build social skills，they added．

16．As the pace of life continues to increase，we are fast losing the art of relaxation．Once you are in the habit of rushing through life，being on the go from morning till night，it is hard to slow down．But relaxation is essential for a healthy mind and body．
Stress is a natural part of everyday life and there is no way to avoid it．In fact，it is not the bad thing it is often supposed to be．A certain amount of stress is vital to provide motivation and give purpose to life．It is only when the stress gets out of control that it can lead to poor performance and ill health．
The amount of stress a person can withstand depends very much on the individual．Some people are not afraid of stress，and such characters are obviously prime material for managerial responsibilities，others lose heart at the first sign of unusual difficulties．When exposed to stress，in whatever form，we react both chemically and physically．In fact we make choice between"flight or fight"and in more primitive days the choices made the difference between life or death．The crises we meet today are unlikely to be so extreme，but however little the stress，it involves the same response．It is when such a reaction lasts long，through continued exposure to stress，that health becomes endangered．Since we can't remove stress from our lives （it would be unwise to do so even if we could），we need to find ways to deal with it．

28．People are finding less and less time for relaxing themselves becauseC．
A．they do not know how to enjoy themselves
B．they do not believe that relaxation is important for health
C．they are travelling fast all the time
D．they are becoming busier with their work
29．According to the writer，the most important character for a good manager is hisA．
A．not fearing stress                  B．knowing the art of relaxation
C．high sense of responsibility        D．having control over performance
30．Which of the following statements is true？B
A．Stress is always harmful to people
B．We can find some ways to avoid stress
C．It is easy to change the habit of keeping oneself busy with work．
D．Different people can withstand different amounts of stress
31．In the last sentence of the passage，"do so"refers toC．
A．"expose ourselves to stress"B．"find ways to deal with stress"
C．"remove stress from our lives"D．"established links between diseases and stress"
