第三部分 阅读理解(共20小题；每小题2分，满分40分) 阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
A
Many facts suggest that children are overweight and the situation is getting worse，according to the doctors.I feel there are a
number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy，fatty foods，such as fried chicken and ice cream，at a low price.This has turned out a whole generation of grown-ups who seldom cook a meal for themselves.If there were fewer of these restaurants，then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight.I agree with this，because good eating habits begin early in life，long before children start to visit fast food shops.If children are given fried chicken and chocolate rather than healthy food，or are always allowed to choose what they eat，they will go for sweet and salty foods every time，and this will carry on throughout their lives.
There is a third reason for this situation.Children these days take very little exercise.They do not walk to school.When they get home，they sit in front of the television or their computers and play computer games.Not only is this an unhealthy pastime(消遣)，it also gives them time to eat more unhealthy food.What they need is to go outside and play active games or sports.
The above are the main reasons for this problem，and therefore we have to encourage young people to be more active，as well as steering them away from fast food shops and bad eating habits. 56．According to the text，what kind of children may eat more unhealthy food?
A．Those who often take exercise. B．Those who often watch television. C．Those who often have meals at home.
D．Those who often walk to school.
[解析] 细节理解题。从倒数第二段的Not only is this an unhealthy pastime，it also gives them time to eat more unhealthy food.可知不健康的看电视的消遣方式会让孩子们吃更多不健康的食物，故选B。

Non-smokers who are being exposed to (面临)cigarette smoke，not only experience its harm physically，but are twice more likely to suffer from major depression，compared to people who are not exposed to black clouds，a large federal study reports.
The study from the University of Miami appears to be the first US research to link secondhand smoke to mood and depression.The new study confirmed exposure to smoke by looking at cotinine levels in the blood of 3000 adults who did not smoke themselves.An additional more than 90000 non-smokers only had to report if they lived with or worked around people who smoked.Every participant was also asked to fill out questionnaires and describe their symptoms of depression.
The results of the blood test showed that individuals in both groups who have been exposed to cigarette smoke on a daily basis，were far more likely to develop symptoms of severe depression.It was found that even people who have been working in public places，where smoking was not banned，were twice more likely to suffer from the condition.According to Frank Bandiera，a public health researcher at the University of Miami School of Medicine，and a lead author of the study，there is no doubt that smokers are exposed to an increased risk of depression in comparison with non-smokers，but the question remains whether the smoking comes first or the depression.
