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.

You like rats? You must be kidding. Everyone hates rats. But rats may soon be man’s new good friend.
What happens after an earthquake? We send in rescue (营救，救援) dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. “Robots’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).Where do you think you can find this passage.
| A．In a magazine about toys. | B．In a history book. |
| C．In a newspaper about science. | D．In an advertisement. |

Which of the following is NOT true?
| A．Rats don’t need electricity. |
| B．Rats are better than robots when smelling. |
| C．Rats are as clever as radios. |
| D．Rats can see things in the dark when doing rescues. |
Which is the best title of this passage?
| A．Ways of saving people | B．Rats |
| C．Rescue dogs | D．Rats for rescue |
There’s always something deep in our soul that never dies. I moved to the small, busy town of Edison in New Jersey six years ago. It was during the second term of my fifth grade. My parents got new jobs and higher income, so they decided it was time to move from Woodbridge to a better, more educational town.
In the US, it is unnecessary to take a test to get into a “good” middle or high school. You just attend the school close to where you live. So, many parents will think about the quality (质量，品质) of the local school when they decide to buy a new house. My parents did the same. We finally chose Edison mainly because of the high quality of its school.
In New Jersey, an area with a good school usually means a concentration of Asian people. There are about 300 students in our school. 55% are Asians and just under half of that are Chinese. There are so many Chinese people nearby that we even have our own Chinese school.
Edison is an old town, just like thousands of others in the United States. However, I have treated it as my hometown. That’s where I spend much of my youth, and the memories there can’t be moved at all.Why did the writer’s parents move to Edison?
| A．Because they were born there. |
| B．Because it was a better educational town. |
| C．Because the writer began his fifth grade. |
| D．Because the writer didn’t need to take a test. |
How many students are from Asia in the writer’s school?
| A．About 80. | B．About 160. |
| C．About 220. | D．About 300. |
What does the underlined expression “a concentration of” mean in Paragraph 3?
| A．None of | B．The whole of |
| C．A large number of | D．A small number of |
Why can’t the writer forget Edison?
| A．Because he regards it as his hometown. |
| B．Because his parents got new jobs there. |
| C．Because there are many Asians there. |
| D．Because it is in the state of New Jersey. |
