My love for words started pretty early. 1 , it was from my eighth birthday. That afternoon I received the first book I would write in from my grandmother. I tore (撕破) open my present to 2 a small blue and white book with the word "DIARY" on its cover.
I looked up at her and asked, "What's a diary?"
She smiled, "It's a(n) 3 book where you can write about the day you hope to have; even your plans for the 4 day. Think of it as a beautiful secret between you and the 5 . Nothing is boring and there are no rules or boundaries."
My joy for words and writing 6 that day. Page after page, I wrote out my thoughts, pains and dreams. And I continued this 7 for most of my high school years.
8 and unknowingly this simple habit became a journey of discovering 9 . I found it was amazing how each entry (条目) was helping me identify (识别) what I liked and disliked, what my hopes and dreams were, as well as whom I was becoming.
10 the years my writing has taken on many styles. Whether it was to know myself, declutter (清除) my mind or get over heartache, words have always been there for me.
It's one thing to live your life, 11 it's another thing to observe (观察) your life and reflect (反映) it through writing. You notice new things, see relationships from broader viewpoints, and find your true love through specific purposes of doing different things.
12 have shown me their true power.

As we know, it is not easy to build a satellite(卫星). 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 maths, 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 CubeSats. At least 15 more are ready to go. Those already in orbit(轨道) take pictures, collect information and send them 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 programme called "KatySat" is carried out for teenagers to take part in. "Once kids understand what satellites can do," says Ben Yuan, an engineer at Lockheed Martin in Menlo Park, California, "the kinds of applications(应用) they'll come up with may be countless."

"We'd like to put this technology 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 thought of yet."

Education isn't the only goal (目标) of CubeSats. Because these tiny, technology-filled boxes are relatively (相对地) 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(垃圾) could 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 about 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" mean?
A. A goal to achieve in the near future.
B. An imagination that kids usually have.
C. Something dangerous to scare people.
D. Something difficult that stands in the way.
( ) 3. According to the passage, which of the following is TRUE?
A. CubeSats could possibly 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 writer's purpose of 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.
