The police find most criminals (罪犯) because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery (搶劫), the police first look through their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in prison (監(jiān)獄). They ask them where they were when the robbery happened. If any of these people cannot give a good answer, the police will often use science to find out if one of them is the robber.
Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair. Or they take something away on their shoes or clothes, like dirt or animal hair. If they leave behind some of their blood or their hair or a piece of skin, it will have their DNA inside it.
Everyone’s DNA is different and their fingerprints are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or even a small piece of skin, scientists can find out what his DNA is. The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA. Many criminals are in prison today because of this kind of evidences .

“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).
Close your eyes and imagine you are living in the next two centuries or more. You'll be living in a world filled with smart robots, which will be helping you to take care of your children, or your elderly parents in your home. You'll live much longer thanks to the medicine made by genetic (基因的) science. And mankind may be going farther in space than ever before-you will be living on the moon or Mars.
How should we view the changes that wait for us in the future? Should we be optimistic (樂觀的)about the years ahead, or worried about what the future holds? Some scientists and experts are having a discussion about how technology, science and society will develop in the future.
"I'm looking forward to the day when more technology will come to my life," says John Searle, a professor at the University of California Berkeley Philosophy, "because I think further research in such areas as genetics, physics, chemistry and medicine will help us to overcome poverty, improve health, and make life longer."
Hugh Herr, at MIT's Biomechatronics Group, considers very powerful weapons as concern over the future. Another is the growing role of technology in our lives."Machines’ taking over what humans do is not a good thing," Herr says.
That is a similar concern shared by Daniela Cerqui, a social and cultural scientist. "I am afraid that the long-term future we are building will have no space left for human beings," says Cerqui. "The main values of our society are related to information that must progress as quickly as possible, and computers are much better than humans in these tasks ."
小題1: The second paragraph mainly tells us ________.
A.how science will develop in the future
B.how people will live in a modern society

D.what computers will bring to our society
小題2:From Paragraph 4 we can infer that ___________.
A.John Searl is optimistic about the future
B.we should wait to see the changes in the future

小題3: The underlined word "That" in the last paragraph refers to________.
A.The poverty problem in the future

Some of the greatest problems we face today are the destruction (破壞)  of our environment. Brown clouds, polluted water,endangered wild animals…. these problems seem so huge.
So my family does what we can. We take cloth bags to stores instead of using plastic bags. We walk where we don't have to drive…

I recently learned something about flamingos(火烈鳥) which like to get together in groups of a thousand or more. Every year, when the time comes for migration(遷徙),a few of them first take off from the lake.  But none of the others seem to notice. So the small group returns. However, the next day they try again. This time a few more fly along with them, but most of them still pay no attention, so they return again. They try for several times. Every time a few more birds join in but, since thousands of the others still take no notice, the great migration plan is once more stopped.
Then one day something changes. The same small group of birds once again starts flying and a small number more join in just as before. then more. Finally, they all take flight and the migration really begins.     What a spectacular sight it must be — thousands of flamingos taking off into the sky at once !

  How could we tell time if there were no watches or clocks anywhere in the world?
The sun is probably the world’s first “clock”, except in the far north, where the Eskimos(愛斯基摩人) live. There, it’s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun as a clock. Even today, if you don’t have a clock, you can still know that when the sun shines, it’s day and when it’s dark, it’s night. The sun can also tell you if it’s morning, noon, or afternoon.
Some people live near the sea from the tides. In the daytime, for about six hours, water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every 24 hours. Seamen on the ship learn how to tell time by looking at the moon and the stars. The whole sky is their clock.
In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock.
A sand clock is an even better clock. If you had fine dry sand in a glass shaped like the one in the picture, you would have what is called an hourglass. The sand in the hourglass goes from the top part to the bottom in exactly one hour. When the hourglass is turned over, the sand will take another hour to go back again
小題1: From the passage we can know there are _______ways to tell time besides the clock and watch.
A.3B.4C.5D.7
小題2:. The Eskimos in the far north can’t use the sun for a clock because________
A.they know very little about the sun
B.the sun there never goes down in winter
C.it’s too cold for them to go out to watch the sun
D.it has long dark winters and long light summers
小題3:. What does the underlined word “tides” mean in the passage?
A.洋流B.潮汐C.海嘯D.波浪
小題4: In which page of newspaper can you probably read this passage?
A.NewsB.ScienceC.AdvertisementD.Sports
小題5: What is the best title for the passage?
A.Different Ways to Tell TimeB.How the Clock Was Invented
C.The Development of the ClockD.A Useful Machine to Tell Time
