     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 (发射) 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 (轨道) 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 (技术) 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.

What are you going to do if you are in a burning house? How will you escape(逃跑)? Do you know how to save yourself? Please read the following passage.

Escaping a fire is a serious matter. Knowing what to do during a fire can save yourself. It is important to know the ways you can use and to show them to everyone in the family, such as stairways (楼梯) and fire escapes, but not lifts.

From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving through windows with the least chance of serious injury (伤害).

The second floor window is usually not very high from the ground. An average person, hanging by the finger-tips (手指尖) will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.

Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked (泄露) into the room.

On a second or third floor, the best windows for escape are those which open onto a roof (屋顶). From the roof a person can drop to the ground more safely. Dropping onto cement (水泥) might end in injury. Bushes and grass can help to break a fall.

1.It is important to ____________________.

A. know the ways to escape a fire      

B. put out a fire in a burning house

C. jump out of a burning house           

D. keep the door closed

2.It is possible to escape through the windows ___________________.

A. if you are strong enough                         

B. if there are some bushes on the ground

C. if you live on a lower floor                         

D. if you have a long rope

3.Keep your head low at the window so that ___________ if the building is on fire.

A. you can get fresh air                   B. you can call for help

C. you can easily jump off                  D. you can be seen first

4.The best title for the passage is _____________.

A. Escaping as fast as possible              

B. Saving Yourself from a Burning House

C. Knowledge on Fire                       

D. Waiting for Help

Who wants to carry a bulky bag to school? No children. Nobody wants one shoulder to be lower than the other, and paining(疼痛)too. In India, most of us would look at the reduction(减少)of textbooks as a way out. But in a country like America, there are always more choices. A company called goReader has created a "school bag" which is the size of a laptop computer(笔记本电脑), weighing about 2.5 kg. The goReader has a color screen and can "hold" all the textbooks that a student may need, says a report in ’The Asian Age’ newspaper.
The company plans to work closely with the publishers(出版商) of textbooks so that these books can be supplied on the Internet. All the students will have to do is to download(下载) their textbooks. Making notes and marking important parts of a lesson can be done just as lots of students have done on their textbooks before.
At present, the plan is being tested out in a university. Richard Katzmann, the owner of the company is having his creation tested at Chicago’s DePaul University, where he studied. Does that mean it is goodbye to the new paper, and the smell of the black ink?
【小题1】What does the underlined word “bulky” in the first line mean?

【小题2】What would Indians do to solve(解决)the problem?
