     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.

      As the Internet becomes more popular, many older media (媒體) businesses are dying out. But

More importantly, recent studies show that people are spending more time watching TV. Surprisingly,
this is even true of young people between the ages of 8 and 18.Today's television industry has given so
many choices. As a result, people can watch more of the things they like 24 hours a day.
     The technology behind television has also improved. The big boxes that once filled living rooms are
gone. Today's TV screens are thinner and thinner, yet the pictures are better and better. TVs are also
moving from living rooms into kitchens and vehicles.
     For years, TVs have also been used as video game players. But now they have been used in a few
new ways. Many televisions can connect to the Internet and record programs. They also let people
watch two programs at the same time. Today the most modern television has been on the way of
development.
     The Internet is the main challenge (挑戰(zhàn)) for television now. But TV industry has shown that

     As we know, there are differences between western culture and Chinese culture. We can see differences
when we pay attention to the words are used. Let's look at the words about animals and plants. Most
expressions in Chinese about the dog, for example,"a homeless dog","a mad dog","a running dog" and "a dog
catching a mouse", have negative (消極的) meanings. But in western countries, dogs are thought to be honest
and good friends of humans. In English, people use the dog to describe positive (積極的) actions. For example,"you are a lucky dog" means you are a lucky person. And "every dog has its day" means each person has good
luck sometimes. To describe a person's serious illness, they say "sick as a dog". The word "dog-tired" means
very tired. However, Chinese love cats very much. But in western culture,"cat" is often used to describe a
woman who is cruel (冷酷的). There are many other examples of how "cat" is used differently as well.
    The rose is regarded as a symbol (象征) of love in both China and some western countries. People think
the rose stands for (代表) love, peace (和平), courage and friendship. And the rose is the national flower of
England, America and many other countries.
    The words about plants and animals are used in positive or negative ways in different cultures. We can
learn about many differences in cultures by comparing how some words are used.
1.  判斷正誤（“T”表示正確，“F”表示錯(cuò)誤）。

     As a large part of land in Hawaii is rocky and mountainous, the state has little space in which to grow
crops. Some areas are also covered with hard, black lava (熔巖) on which nothing can grow. Even so,
Hawaii produces large quantities of farm products.

possible to grow crops all year long. Rainfall is plentiful on the northern and eastern sides of each island.
Much of the land on the southern and western sides of each island receives too little rainfall for most crops
to grow well, but in many of the places where rainfall is light, wells and mountain streams supply water for
irrigation.

     As a child, I was really afraid of the dark and of getting lost. These fears were very real and caused me
some uncomfortable moments.
     Maybe it was the strange way things looked and sounded in my own room at night that scared me so
much. There was never complete darkness, but always a streetlight or passing car lights, which made clothes
on the back of a chair take on the shape of a wild animal. Out of the corner of my eye, I saw the curtains (窗
簾) seem to move when there was no wind. A very low sound in the floor would seem a hundred times louder
 than in the day. My imagination (想象) would run wild, and my heart would beat fast. I would lie very still so
that the"enemy(敵人)" would not discover me.
     Another of my childhood fears was that I would get lost, especially on the way home from school. Every
morning I got on the school bus right near my home. That was no problem. After school, though, when all the
buses were lined up along the street, I was afraid that I would get in the wrong one and be taken to some other
strange places. On school or family trips to a park or a museum, I wouldn't let the leaders out of my sight.
     Perhaps one of the worst fears of all I had as a child was that of not being liked or accepted by others.
Being popular was so important to me then, and the fear of not being liked was a serious one.
     One of the processes (過程) growing up is being able to realize and overcome our fears. Understanding the
things that scared us as children helps us achieve greater success later in life.

1. The author had _____ kind(s) of fears when she was a child.
A. one
B. two
C. three
D. none
2. _____ would scare the author at night.
A. Streetlight and car lights
B. Wild animals and enemies
C. Moving curtains and wind
D. Strange sights and sounds
3. When she went to some other places, she would _____.
A. walk away without others
B. take a bus by herself
C. follow others closely
D. make sure not to take a wrong bus
4. Which of the following would be possibly true when she was a child?
A. She was usually popular among people.
B. She was always the leader of the others.
C. She always' got poor grades.
D. She was not at all liked by others.
5. The underlined word "overcome" means "_____" in Chinese.
A. 接受
B. 忍受
C. 信服
D. 克服
