The summer beach season is prime time for shark attacks. It seems like sharks are attacking all the time .But that is something of an illusion. The number of attacks is very small.

   How does a shark hunt? Muscles and fins (鳍)give the shark its speed and maneuverability(灵活)in the water. A shark’s front fins act like the wings of a plane and let it “fly” through the water. The tail acts like a high-power propeller(推进器).

But the big thing that gives the shark its edge in the ocean is its sensory package. The package includes the shark’ eyes ,ears ,skin, nose and mouth, as well as electric sensing.

   A shark' nose is probably its most important sense.  If you were to put a single drop of blood in a swimming pool ,a great white shark could smell that. And they can tell the direction that the smell is coming from.

   Sharks handle their electric sensing using cell located in the head .Whenever something moves using its muscles , a shark can detect the electrical impulses（ 脉冲）flowing to those muscles. A shark can electrically “see” anything that has muscles even if it is hiding or the water is not clear.

   Sharks even have vibration sensors in their skin. Even something moves near  the shark ,tubes pick up the pressure changes and hairs inside the tubes send signals to the brain . This extra sense allows a shark to turn quickly and attack again.

   When you put all these different senses together ,it makes the shark a nearly ideal hunter. A shark can detect prey from miles away and then use eyes ,electrosensing and movement sensing to home in .

   Strangely, sharks do not seem to use these senses to home in on people. The very low number of sharks tells us that sharks do not hunt people on a regular basis. On the other hand , people love to hunt sharks. Millions of sharks die every year. Without protection ,extinction is a definite possibility.

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 （包围） 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（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.

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.

A．their parents often cook meals for them
