Question

As we know, it is not easy to build a satellite(衛星). Building a traditional satellite usually 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(學歷) in math, science, or engineering.

But things are changing. High costs, unusual educational needs and long start-up times are no longer an obstacle(障礙) to space exploration. The scientists have developed a new type of tiny, inexpensive earth-orbiting(軌道) satellite.
So far, college students have built and launched(發射) several cube-shaped satellites, or CubeSats. At least 15 more are ready to go. Those already in orbit 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 KatySat aims to get teenagers to take part in. When kids understand what satellites can do, the kinds of ideas they’ll come up with may be countless.
Education isn’t the only aim of CubeSats because these tiny, technology-filled boxes are  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. Or space junk could gradually increase because CubeSats become more popular.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space. Someday—perhaps a lot sooner that you imaging—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 about science for life.

試題分析：本文介紹的是新型的衛星，它比傳統衛星的造價低，省時，省錢。但是由于太空垃圾越來越多，可能對環境造成影響，這項技術也會在學校被學生們所學習。
小題1:細節理解題。根據原文Building a traditional satellite usually takes years.可知建造一個傳統的衛星要花費好多年，故選C。
小題2:細節理解題。根據原文The scientists have developed a new type of tiny, inexpensive earth-orbiting(軌道) satellite.可知新的衛星即便宜有迷你。故選B。
小題3:細節理解題。countless意為“無數的”，故選C。
小題4:細節理解題。根據原文Or space junk could gradually increase because CubeSats become more popular.空間垃圾可能會增加。故選A。
小題5:細節理解題。根據原文Nowadays, college and high school students are getting a chance to learn可知這項技術在學校也可以被孩子們所學習。故選A。
