阅读短文，根据其内容回答问题。         The idea of daylight (日光) saving time started with an American named Benjamin Franklin (1706-1790).
He explained how a lot of the money spent on candles used for light (This was before electricity电) could be
saved if everyone woke up earlier and went to bed earlier.
         Even though Franklin"s idea had a clear meaning, most people didn"t want to get up earlier than they had
to. Who would?
        An Englishman named William Willet didn"t come up with a way to "make" the sun set (落下) later until
1907. His idea was to turn clocks forward (向前) by 20 minutes on each of the four Sundays in April, for a
total (总计) of 80 minutes.
        William"s idea was laughed at, at first. But when World War I started in 1914, many countries decided
they had to save energy (能源) for the war.
        Daylight saving time has other uses. The more time you spend outside playing, the less time you are
spending in front of the computer or the TV. These things also use energy.
        Also, daylight saving time sometimes causes problems. For example, China used it in 1986 —but stopped
it in 1991. That was because the temperatures are quite different from North to South and time from East to
West.
        If the people from northwest part of China use daylight saving time, sometimes they have to get up to
work when it is not very bright outside. That will cause some trouble for them.
       Still, most parts of the world do have daylight saving time, and most people look forward to the extra
(额外的) hour of evening light.
1. Did the idea of daylight saving time start with an American named Benjamin Franklin?

举一反三

阅读理解。          New rules and behavior standards (行为规范) for middle school students came out in March. The Middle
School is going to use a new way to decide who the top students are. The best students won"t only have high
marks. They should not dye (染) their hair, smoke or drink because they are students. The following are some
of the new rules.
         Have you ever copied someone else"s work in an exam? Don"t do that again! That"s not something an
honest student should do.
         Do more at school. Good students love animals and care for other people. April is Bird-loving Month in
China. Is your school doing anything to celebrate it? You should join! And you can learn more about animals
and how to protect them. Be friendly to the people around you. Try to think of others, not only yourself.
          Be open to new ideas. Do you think people can live on the moon? Maybe you"ll find another earth
someday. Don"t look down on new ideas. Everyone"s ideas are important. You should welcome them, because
new ideas make life better for everyone.
          Protect yourself. Has someone ever taken money from one of your classmates? Don"t let it happen to
you. If you have to go home late, you should let your parents know.
          Use the Internet carefully. The Internet can be very useful for students. But some things on the Internet
aren"t for children, so try to look at web pages (网页) that are good for you. 1. What"s the meaning of "look down on " in the passage?[     ]
A. 向下看
B. 轻视
C. 在……上面看
D. 上下打量2. If you go home late, you should tell your             about it.[     ]

阅读理解。 Birds Journeys

        The wish that shows birds to begin their journeys, and the highly exact feeling of direction shown by
traveling birds, stay among the most puzzling mysteries of science. The Arctic tern and the golden plover are
two examples of these unusual birds.
        In the north during the springtime, traveling birds return to the Arctic (北极) from southern areas.
The longest journey is made by the unbelievable Arctic tern. This amazing bird is no larger than a crow (a
kind of bird) , but its body surface (outside) is more updated. The tern is called the long-distance champion
of the bird world, often traveling 23,000 miles a year between West Africa and the Arctic. Such journeys
take weeks, with stops for food and rest.

        There are no rests, however, for the golden plover, a non-stop flyer among Arctic birds. The plover"s
journey is like that of a land plane over water, since the plover cannot land on the water to rest. Without
stopping, the golden plover flies 2,000 miles from Hawaii to Alaska or from South America to Nova Scotia
and northern Canada. This little bird (only eleven inches) is fat and strong when traveling north, but is thin
and weak when it arrives after fighting ocean winds for sixty or more hours.1. Look at the first paragraph. What does the underlined word "mysteries"mean?[     ]
A. 秘密
B. 神秘
C. 机密
D. 隐秘2. What do the tern and the plover have in common?[     ]

                                                             How Long Can People Live?
       She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the
neighborhood on her 121st birthday.
        When it comes to long life, Jeanne Calment is the world"s recordholder. She lived to the ripe old age
of 122. So is 122 the upper limit to the human life span (寿命)? If scientists come up with some sort of pill
or diet that would slow aging, could we possibly make it to 150-or beyond?
        Researchers don"t entirely agree on the answers. "Calment lived to 122, so it wouldn"t surprise me if
someone alive today reaches 130 or 135," says Jerry Shay at the University of Texas.
        Steve Austad at the University of Texas agrees. "People can live much longer than we think," he says.
"Experts used to say that humans couldn"t live past 110. When Calment blew past that age, they raised the
number to 120. So why can"t we go higher?"
        The trouble with guessing how old people can live to be is that it"s all just guessing. "Anyone can make
up a number," says Rich Miller at the University of Michigan. "Usually the scientist who picks the highest
number gets his name in Time magazine."
       Won"t new anti - aging techniques keep us alive for centuries? Any cure, says Miller, for aging would
probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the
life span of mice by 50 percent at most. So, if the average human life span is about 80 year, says Miller,
"adding another 50 percent would get you to 120."
       So what can we conclude from this little disagreement among the researchers? That life span is flexible
(有弹性的), but there is a limit, says George Martin of the University of Washington. "We can get flies to
live 50 percent longer," he says. "But a fly"s never going to live 150 years." Of course, if you became a new
species (物种), one that ages at a lower speed, that would be a different story, he adds.
       Does Martin really believe that humans could evolve (进化) their way to longer life? "It"s pretty cool to
think about," he says with a smile.

1. What does the story of Jeanne Calment prove (证明) to us?[ ]
A. People can live to 122.
B. Old people are creative.
C. Women are sporty at 85.
D. Women live longer than men. 2. According to Steve Austad at the University of Texas, _______.[ ]

阅读理解。        When you go looking for fossils, don"t take too many things with you. A bag full of heavy fossils is quite
enough to carry home. But you need to remember:
1.

Take a hammer with you for breaking open rocks (岩石). A hammer is the best kind to use. A pair of
glasses will stop flying pieces of stones from hurting your eyes.
2.

A hand lens is useful. You might find fossils that are too small to see clearly. With a hand lens you can
examine the small things better.
3.

Take a map of the area you"re visiting to show you where you might find the fossils, plus a ruler for
measuring(测量) the fossils you find.
4.

A camera will be useful for photographing interesting rocks which stand up out of the ground. That"ll
help you to remember where you found the fossils.
5.

Number your fossils and wrap (包、裹) them in newspapers before putting them into your bag.
6.

Make sure that your clothing is suitable for the weather in whatever kind of countryside you are visiting.
7.

You have to take a notebook and pencils. As soon as you find something interesting, take a note of
where you found it and the kind of rock in which it was found.

阅读理解。       There have been many great inventions, things that changed the way we live. The first great invention
was one that is still very important today -the wheel. This made it easier to carry heavy things and to travel
a long distance.
       For hundreds of years after that there were few inventions that had as much effect (作用) as the wheel.
Then in the early 1800"s the word started to change. There was little unknown land left in the world. People
didn"t have to explore much anymore. They began to work hard to make life better.
       In the second half of the 19th century many great inventions were made. Among them were the camera,
the electric light and the radio. These all became a big part of our life today.
        The first part of the 20th century saw more great inventions. The helicopter (直升飞机) in 1909. Sound
movies in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was
first made. Nylon came out in 1935. It changed the kind of clothes people wear.
       The middle part of the 20th century brought new methods (方法) to help people get over diseases. They
worked very well. They made people healthier and let them live long lives. By the 1960"s more people could
expect to live to be at least 60.
        By this time most people had a very good life. Of course new inventions continued to be made. But man
now had a wish to explore again. The world is known to man but the stars are not yet. Man began looking for
ways to go into space. Russia made the first step. Then the United States took a step. since then other countries,
including China and Japan, have made their steps into space.
        In 1969 man took his biggest step away from earth. American first walked on the moon. This is certainly
just a beginning though. New inventions will someday allow us to do things we have never yet dreamed of.
