Satellites play big roles in modern life. Some look downward to monitor environmental conditions on Earth.Others look outward in search of major solar flares(耀斑) that can trouble the transmission(传送) of electrical power to homes and businesses. Some spy on our enemies. Others relay communications around the globe. But all of these million-dollar wonders of technology can be knocked out by a collision with space junk ---debris (碎片 )from satellites and other earthly technology orbiting high above the planet. Now,a teen from Jordan has designed a satellite to chase down space junk , collect it and then deal with it.
Even bits of space junk as small as dots of paint pose a threat , says Dana. That's because this debris orbits our planet at speeds up to some 28,200 kilometers per hour. Such high speed explains why tiny paint dots have damaged the windshields of space shuttles so badly that they needed to be replaced.
Researchers have come up with many ideas for getting rid of space junk. Some have suggested vaporizing(蒸发) small bits with lasers. Others have proposed launching satellites to collect the debris. Dana's design falls into this category.
Here's how hers would work : A radar system aboard the satellite would scan and find a piece of space junk.Then,thrusters(推进器)would change the satellite's orbit so that it could chase down the errant object. As the satellite closed in on its prey, cameras would keep it on target.
At the last minute,a door that leads to a container would open. This container needs to be strong so that it doesn't break apart when the satellite swallows the space junk,Dana explains. Finally,when the trash container was full,it would be lowered toward the earth on a kilometer-long cable and its contents released into the upper atmosphere. There, the space junk would harmlessly burn up just like a meteor (流星) does. Meanwhile, her satellite would roll the container back up so that it could collect more trash.

A new study supports the view that jobs aren't simply a love-at-first-sight deal. Rather, they say that achieving passion for your work is something you can develop over time.
Unlike the main way of thinking that you'Il only achieve passion for your work through finding the right fit with a line of work - what the researchers call "fit theory" , the researchers say you can learn to love your job and find meaning in it gradually(“developing theory").
We probably hear and think a l.t more about "fit theory" than “developing theory" because we've become used to it. "Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work," said Steve Jobs. “And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'II know when you find it. "
Chen and colleagues examined some students' career attitudes and expectations with regard to "fit theory"and "developing theory". "People can achieve similar levels of passion at work by accepting either the fit or develo-ping theory. The key difference lies in how these results are reached : fit theorists(理论家) tend to self-select into lines of work that fit them from the start, while developing theorists grow into that fit over time. "
Fit theorists tend to value enjoyment at the expense of good pay, while developing theorists are willing to let enjoyment take a back seat to other goals, safe in the knowledge that they'll grow into the role and find enjoyment over time.
Everyone has moments of being bored with their work,but it's important to keep your thoughts focused on the bigger picture, your Iong-term goals , and whv you took the role in the first place.

2.The writer quoted Steve Jobs' speech to prove____________.
A. the romantic idea of "fit theory"

A. consider your situation as a whole
B. try other new jobs as soon as possible
C. consider your role in your work first
D. start your work from the beginning again
4.What might be the best title for the passage?
A. You Will Have Passion for Your Work
B. You Can Learn to Love Your Job
C. You Will Finally Achieve Your Job Goal
D. You Can Get Enjoyment from Your Work
My mother is taking a tour of the new house via Skype. I leaned the laptop so she can see where she's going,pleased that our Internet connection in Zimbabwe is holding.

But an afternoon's searching yielded only a pink plastic toilet and sink. It doesn't matter,l told myself. I showed Cassia how to make plates for her table from coloured buttons. Fascinated, she collected black stones.
What my mother gave me was much more than a fascination with tiny things :It was the ability to view things from a new perspective(角度) , to put oneself in another person's shoes , and to solve problems with whatever is at hand.

Design your own adventure spent at IZE's Blue Creek Field Station by choosing activities per day from the list below.
Short Cave Hike: 2-hour activity where you will be exposed to the ultimate tropical rainforest experience. At every turn along the trail,a novel experience awaits. Perhaps it's a trail of leaf cutter ants (切叶蚁) or a delicate tree snake. You will follow your Maya Guides up a steep incline(斜坡) to the entrance of one of the most wonderful limestone caves in Belize.
Ethnobotany Walk: 3-hour activity where you will explore the medical and cookery uses of the local herbs,plants and trees.

No one lives without a dream. Whether the path is smoothly or tough,we are on the path to achieving it . As a senior 3 student, I have the same dream like my classmates that I can be admitted to an ideal university. In the past three years, I have done everything I can equip myself with that I have learnt from my teachers. Not only have I enjoy the pleasure of study but also I have got closer to my dream. Anxiety and pressure discourage him now and then. Therefore, with the encouragement of my teachers and classmates, I think I’ll make out it.
I’m sure that there is still a long way to go to achieve my dream. No matter how challenged it is, I’ll make it come true. As the proverb says,“Where there has a will, there’s a way.”
