Ⅵ.阅读理解
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 low prices.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，but 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.
46．According to the text，what kind of children may eat more unhealthy food?
A．Those who often do sports.
B．Those who often watch television.
C．Those who often have meals at home.
D．Those who often walk to school.
答案  B
解析细节理解题。根据倒数第二段中的“When they get home，they sit in front of but it also gives them time to eat more unhealthy food.”可知，经常看电视的人可能吃更多不健康的食品。所以答案选B。
47．The underlined word “steering” in the last sentence most probably means “”．
A．forcing B．guiding
C．driving D．moving
答案  B
解析词义猜测题。根据语境可知，作者想说，我们应该鼓励年轻人积极起来，也要“steer”他们远离快餐店和一些不好的饮食习惯。所以可以猜测“steer”是指guide“指导，引导”。故选B。
48．The main purpose of the text is to .
A．tell a story B．provide facts
C．give advice D．compare opinions
答案  C
解析写作目的题。作者一开始提出“Many facts suggest that children ”分析了孩子们变胖的三个主要原因；结尾处又讲到“encourage young ，as ”鼓励年轻人多活动，引导他们远离快餐和不好的饮食习惯。故选项C“给建议”为正确答案。
B
In the near future，we may be using our eyes to operate our smart-phones and tablets，even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities，and are very expensive.
“After a while，we figured out that probably the best way is to go for a mass-market way，”says Gaze’s Sune Alstrup Johansen，“where everybody would have this available.”
Johansen and some of his colleagues have formed a new company，The Eye Tribe，which is hoping to develop the technology on a mass commercial level.
The technology works when combined with the computing device toward the user’s face.After making sure of the user’s eye movements，the technology is then able to easily find where a person’s eyes are moving，and then allow the eyes to control a cursor(光标)．“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at，” reads an explanation on The Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years，particularly in the gaming world.Recently Xbox released the Kinect device，which lets users control their Xbox and play certain games using only their hands，legs and voices.But still，most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器) would be a cheap，convenient way for most
consumers.
And even as companies like The Eye Tribe work to create such a product for the average user，making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

50．The underlined word “gimmick” in the passage probably means “”．
A．truth B．phone
C．trick D．review
答案  C
解析词义猜测题。根据画线词所在句可知，它不是一种用手控制移动设备的实用方法，由此可以猜测出这些设备大多只是一种噱头，也就是一种用以吸引人的技巧，故画线词gimmick 的意思是：trick(技巧，诡计)。故选C。
