     As we know, it is not easy to build a satellite. Building a traditional satellite normally takes years. The
costs can be as high as $ 250 million or more. Most members of the design teams have worked in the field
for a long time. They hold advanced degrees in math, science, or engineering.
     But things are changing. High costs, unusual educational requirements and long start-up times are no
longer an obstacle to space exploration. The scientists at Stanford University have developed a new type of
tiny, inexpensive earth-orbiting satellites that go from ideas to launch (發(fā)射) in a year.
     So far, college students have built and launched several cube-shaped satellites, or Cube Sats. At least 15
more are ready to go. Those already in orbit (軌道) take pictures, collect information. and send it back to the
earth, just as regular satellites do.
     But you might not even have to wait until you get to college to start designing and building your own
satellite. A new program called Katy Sat aims to get teenagers to take part. Once kids understand and what
satellites can do, says Ben Yuan, an engineer at Lockheed Martin in Menlo Park, Calif, the kinds of applications
they'll come up with may be countless.
     "We'd like to put this technology (技術(shù)) in your hands," he tells kids." We're going to teach you how to
operate a satellite. Then we want to turn it over to you as a sandbox for you to play in. We want you to take
the technology into new directions that we haven't though of yet."
     Education isn't the only goal of Cube Sats. Because these tiny, technology-filled boxes are relatively
inexpensive to build and can be put together quickly, they're perfect for testing new technologies that might
one day be used on major space tasks.
    The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two.
Otherwise, major highways of space junk could gradually increase as CubeSats become more common.
     Nowadays, college and high school students are getting a chance to learn what it takes to explore in space.
Someday-perhaps a lot sooner than you imagine-you might get to design, build and launch your own satellite.
If you do, you're sure to have fun. And you might also get crazy a-bout science for life.
1. Compared with the traditional ones, the new satellites ______.
A. need long start-up times
B. are low-cost and small-sized
C. are very hard to operate
D. collect more information in orbit
2. What does the underlined word "obstacle" probably mean?
A. An aim to achieve in the near future.
B. An imagination that kids usually have.
C. Something dangerous to terrify people.
D. Something difficult that stands in the way.
3. According to the passage, which of the following is true?
A. CubeSats could possible cause pollution in space.
B. A few kids will send applications for the project.
C. Scientists designed CubeSats for kids to play with
D. Students can't design satellites without college education.
4. What's the purpose of the author writing the passage?
A. To show that high technology brings a big change in kids' life.
B. To show that kids lead the space research into a new direction.
C. To tell us that satellite technology can also be learned by kids.
D. To tell us that kids must study hard to learn satellite technology.

Two weeks ago, Ruichang City in Jiangxi Province was hit by an earthquake measuring 5.7 on the Richter scale(里氏震級). It killed 18 people and left hundreds homeless.

　  Earthquakes are one of the most deadly natural disasters(災(zāi)難) in the world. They happen more often than you would expect.

　  In the 24 hours after you read this, 400 to 500 earthquakes will shake the earth. You won't notice most of them because you live in a relatively(相對地) safe area or the quake is too far away or because the quake will be too small to notice.

　  Earthquakes are caused by sudden breaks in rock masses(群) deep in the earth. Rock masses are always under very high pressure. If the pressure in a certain area become too much and the rock masses break, an earthquake happens. But exactly when the rock masses reach the breaking point is a mystery(謎).

　  China is on the Eurasia(歐亞) plate, where earthquakes happen very often due to the earth's plates knocking against each other. Up to 17,139 earthquakes have taken place in China in the past 44 years, according to scientific research.

Once upon a time a woman found she was not easy to wake up in the morning as early as she wished. So she bought a beautiful alarm clock. These clocks are so made as to strike with loud whirring noise at any hour the owner pleases to set them.

The lady placed her clock at the head of the bed, and at the right time she found herself roused by the long, rattling sound.

She got up at once, and felt better all day for her early rising. This lasted for some weeks. The alarm clock faithfully did its duty, and was plainly heard so long as it was obeyed.

But, after a time, the lady grew tired of early rising. When she was waked by the noise, she merely turned over in bed, and slept again.

In a few days, the clock ceased to wake her from her sleep. It spoke just as loudly as ever; but she did not hear it, because she had been in the habit of not obeying it.

Finding that she might as well be without it, she made up her mind that when she heard the sound she would jump up.

Just so it is with conscience(自覺意識，誠意). If we will obey its voice, even in the least important things, we can always hear it, clear and strong.

But if we allow ourselves to do what we have some fears may not be quite right, we shall grow more and more sleepy, until the voice of conscience has no longer power to wake us.

4Why did the clock failed to stop to get the woman up later?

A. Because she was tired of getting up early in the morning.

B. Because she could not hear the clock any more.

C. Because she was too tired to wake up at it.

D. Because the clock stopped to do its duty.

5 Both the underlined words “whirring” and “rattling” are kinds of ______.

A. colours                        B. sounds         C. actions                   D. feelings

6 The writer mainly wants to tell us that ______.

A. we should always obey our clocks

B. the clock sometimes can’t wake us up as we wish 

C. It is conscience that ensures early rising not the clock

D. The voice of conscience has no longer power to wake us.

   

Amy was a dear little girl, but she was too ready to waste time in getting ready to do her tasks, instead of doing them at once as she ought to.

In the village in which she lived, Mr. Thornton kept a store where he sold fruit of all kinds, including berries in their season. One day he said to Amy, whose parents were quite poor, “Would you like to earn some money?”

“Oh, yes, ” replied she, “for I want some new shoes, and papa has no money to buy them with.”

“Well, Amy,” said Mr. Thornton, “I noticed some fine, ripe blackberries in Mr. Green’s field today, and he said that anybody was welcome to them. I will pay you thirteen cents a quart(度量單位) for all you will pick for me.”

Amy was delighted at the thought of earning some money; so she ran home to get a basket, intending to go immediately to pick the berries.

Then she thought she would like to know how much money she would get if she picked five quarts. With the help of her slate(書寫板) and pencil, she found out that she would get sixty-five cents.

“But supposing I should pick a dozen quarts,” thought she, “how much should I earn then?” “Dear me!” she said, after figuring(測算) a while, “I should earn a dollar and fifty-six cents.”

Amy then found out what Mr. Thornton would pay her for fifty, a hundred, and two hundred quarts. It took her some time to do this, and then it was so near dinner time that she had to stay at home until afternoon.

As soon as dinner was over, she took her basket and hurried to the field. Some boys had been there before dinner, and all the ripe berries were picked. She could not find enough to fill a quarter of a quart.

As Amy went home, she thought of what her teacher had often told her---“Do your task at once; then think about it,” for “One doer is worth a hundred dreamers.”

7How many times did Amy figure with her slate?

   A. 3.                               B. 4.                         C. 5.                     D. 6. 

8The underlined sentence may mean “______”.

A. she got ready to waste some time to do her tasks

B. she thought it was a waste of time to do her tasks

C. she liked to waste time when should do her tasks immediately

D. she was not ready to get her tasks ready, and it’s a waste of time

9What can we infer from the story?

A. Amy’s family was very poor.

B. Amy was good at counting with a slate.  

C. Mr. Thornton was the richest person in the village.

D. Amy would learn a better lesson from this affair than from school.        

10 The best title of the passage may be “_____”.

A. The Money Amy Did Not Earn               

B. The Girl Did Not Like To Waste Time    

C. Amy, A Good Student To her Teachers

D. A Poor Girl Wanted To Earn Some Money
