A new kind of Sports shoes have been worked out in the UK recently. They can work out whether their owner has done enough exercise to allow time in front of the television.

The shoes-named Square Eyes-have an electronic sensor and a small computer chip (芯片) to record how many steps the wearer has taken in a day.A wireless transmitter(无线传导器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer can have, depended on the day’s efforts.

The idea was encouraged by a wish to fight against overweight among British teenagers, says Gillian Swan, who developed Square Eyes. “We considered the problems and childhood overweight really stood out.” She says, “And I wanted to work out that with my idea.”

Once a child has used up their daily allowance(许可) got through exercise, the television itself turns off. And further time in front of the TV can only be got through more steps.

Swan thought over how exercise should change to television time.Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television.So, every 100 steps recorded by the Square Eyes shoes means one minute of TV time.

Other similar sports shoes normally keep count of steps by measuring(测量) sudden movement. Swan says people may easily get recording steps through shaking. But her shoes have been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main invention considerations.”

(  )61.According to Swan,the purpose of her sports shoes is to________.

A. keep children away from the TV   

B. deal with overweight among teenagers

C. keep a record of the steps of the wearer 

D. prevent children from being cheated by TV programs

(  )62.Which of the following is TRUE of Square Eyes shoes?

A. They control a child’s daily exercises.

B. They record all the information of the receiver.

C. They control a child’s evening TV viewing time.

D. They have caused the problem of watching TV too much.

(  )63.Compared with other similar products, Swan’s sports shoes ________ .

A. make it hard for lazy teenagers to cheat

B. count the wearer’s steps through shaking

C. record the sudden movement of the wearer

D. send teenagers’ health information to the receiver

(  )64.Health experts suggest that a child should take________ .

A. 12,000 steps each day

B. watch more than two hours of television.

C. 100 steps one minute

D. keep count of steps by measuring sudden movement

(  )65.Which of the following would be the best title for the text?

A. Smart Shoes Stop Childhood Overweight

D. Smart Shoes Decide on Television Time

Do you know why different animals or insects have their special colors? Colors are used mainly to protect themselves.
Why can’t some birds easily catch locusts(蝗虫)? It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as autumn comes, locusts change to the same brown color as crops have. Some other insects with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives in the day and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals can’t be easily seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even more strange thing? A kind of fish in the sea can send out black liquid when it faces danger. While the liquid spreads over, its enemies can’t find it. And it quickly swims away. So it has lived up to now though it is not strong at all.
