Everybody hates rats．But in the earthquake capitals of the world-Japan，Los Angeles，Turkey-rats will soon be man's new best friends．
What happens after an earthquake? We send in rescue（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（信號）．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．Christian Linster at Cornell University—New York says，“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 Julie Ryan of International Rescue Corps in Scotland says，“It would be fantastic．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）．
小題1:In the world earthquake capitals，rats will become man's best friends because they can _________．
A．take the place of man's rescue jobs
B．find the position of people alive who are trapped in buildings
C．serve as food for people alive who are trapped in buildings
D．get into small spaces
小題2:From the third paragraph we know the rescuers can judge a person is alive by_________．
A．the noise made by the ratB．the rat's unusual behavior
C．the signal sent by the radio on the rat's backD．the smell given off by the person
小題3: In doing rescue jobs，_________．
A．rats smell better than dogs
B．dogs don't need to be trained to smell people
C．robots' sense of smell can be affected by other smells around
D．rats can see in the dark and smaller than robots
小題4: Rats have all the following advantages except that_________．
A．they are more fantastic than other animalsB．they are less expensive to train than dogs

My elder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult.
For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had soared through Mrs. Holt’s basement window, breaking the glass with a crash, Steve encouraged me to confess（承認(rèn)）to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball. I also learned from Steve that personal property is a sacred（神圣的） thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I’d hate to lose to someone else the small dog that my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on my shoulder.
Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind. When I was twelve, I killed an old brown sparrow in the yard with a BB gun. Excited with my accuracy, I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, “Did it hurt you first, Mark?” I didn’t know what to answer. He continued with his eyes firm, “The only time you should even think of hurting a living thing is if it hurts you first. And then you think a long, long time.” I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.
小題1: What is the main subject of the passage?
A．The relationship between Mark and Steve.
B．The important lesson Mark learned in school
C．Steve’s important role in mark’s growing process.
D．Mark and Steve’s respect for living things.
小題2:It can be inferred from the passage that when Mark confessed to Mrs. Holt, __________.
A．he felt surprisedB．he was light-hearted
C．he felt frightened D．he knelt before her
小題3:In the story about the pen, which of the following lessons did Steve teach his brother?
A．Respect for personal property.B．Respect for life.
C．Sympathy for people with problems.D．The value of honesty.
小題4:According to the writer, which was the most important lesson Steve taught his young brother?
A．Respect for living things.B．Responsibility for one’s actions.
C．The value of the honesty.D．Care for the property of others.
小題5:Which of the follow is true according to the passage?
A．Mark was still a boy when he wrote this passage.
B．Mark lost the small dog his father carved somewhere.
C．When a living thing hurts you, you should kill it.
D．Even if a living thing hurts you, you should not kill it without hesitation.

Geena David knew she wanted to be a movie star when she was very young. She was not sure what gave her the idea, but she wanted to look like a movie star. “I have a lot of pictures from my childhood of me wearing sunglasses,” she says. “I used to wear them to watch TV.”
　 Early movie actors started wearing sunglasses not because they looked good, but because their eyes hurt. The lights used on movie sets were extremely bright and could cause a painful problem known as “Klieg eyes”. It was named after the Klieg brothers who invented the lights. Actors wore sunglasses to give their eyes a rest. But when movie stars began wearing their sunglasses in public, they quickly became a must.
　 Eventually actors started wearing sunglasses in their movies as well as on the street. Audrey Hephburn wore ultra-cool Ray-Ban sunglasses in the 1961 movie, Breakfast at Tiffany’s. As a result, Ray-Ban sunglasses started to appear more and more in the movies. In 1979, Ray-Ban “Wayfarers” were worn by Jake and Elwood in The Blue Brothers. Tom Cruise wore Ray-Ban “Aviator” sunglasses in the 1986 hit, Top Gun. Then in 1997, Will Smith and Tommy Lee Jones made Ray-Ban “Predator” sunglasses famous in Men in Black.
　  Of course sunglasses aren’t just a fashion statement. The main reason to wear sunglasses is to protect our eyes against UV radiation. UV radiation can damage our eyes, so people now choose their sunglasses carefully. But you don’t have to give up style for safety. The choice of frames and lenses available these days is huge. So you can protect your eyes and still be the coolest person on the beach.
小題1:What is mainly discussed in this passage?
A．The use of sunglasses.B．The history of sunglasses.
C．The sunglasses wearing.D．Why movie stars like to wear sunglasses.
小題2:Why did Geena David like to wear sunglasses?
A．She was a movie star.
B．She wanted to follow a movie star.
C．Wearing sunglasses was good to her eyes.
D．It was good to wear sunglasses when watching TV.
小題3:Early actors’ eyes hurt because ______.
A．they wore sunglasses
B．they went out in the sun too much
C．the lights on movie sets were too bright
D．their scripts were written in very small writing
小題4:Now people wear sunglasses ______.
A．just to protect their eyesB．for fashion and to protect their eyes
C．because of bright lightsD．because movie stars wear them
