Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.What happens to people attacked by sharks?

Many people like to travel by plane , but I don't like it because an airport(飞机场) is usually far from the city. You have to get early and wait for hours for the plane to take off and it is often late. You can’t open the windows. You can’t choose the food. Planes are fast, but they still take hours to go out the airport and into the city.
I like traveling by train. I think trains are safe. Train stations are usually in cities. When you are late for a train, you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (迁徙) is probably the migration of fish, which is called “salmon”(蛙鱼). This fish is born in fresh(淡的) water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel. Most animals move from one place to another at a certain time to _______.
| A．enjoy warmer weather |
| B．find food more easily |
| C．find beautiful places |
| D．get away from crowded places |
The underlined word “There” in the second passage means “___________”.
| A．in cold water | B．in warm water |

Why do the lobsters get into a long line to move?
| A．It’s a safe traveling way. |
| B．The weather is bad. |
| C．It is still unknown to us. |
| D．They just don’t want not to be too crowded. |
The passage is mainly about ________________.”
| A．the migration of animals |
| B．the migration of fish |
| C．the travel of animals |
