Unless we spend money spotting and preventing asteroids(小行星) now, one might crash into Early and destroy life as we know it, say some scientists.
Asteroids are bigger versions of the meteoroids(流星) that race across the night sky. Most orbit the sun far from Earth and don’t threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth.
Buy $50 million worth of new telescopes right now. Then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’ll have a way to change its course.
Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’t be cheap. Is is worth it? Two things experts consider when judging any risk are: (1)How likely the event is; and (2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500 000 years. Sounds pretty rare-but if one did fall, it would be the end of the world. “If we don’t take care of these asteroids, they’ll take care of us,”says one scientist. “It’s that simple.”
The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday(世界末日) rocks than from a great nuclear fleet set against it,” said a New York Times article.

A Leap（跳跃）to Honor
Leaping on a narrow balance beam（平衡木） is not easy. But Lola Walter, a 13-year-old gymnast, is an expert at it.
To perfect her skills, Lola 36 for four hours a day, five days a week. At the state championships in March, she finished seventh out of 16 girls.
That’s especially impressive, 37 she is legally blind, born with a rare condition that causes her eyes to shift constantly. She often sees double and can’t _38 how far away things are.
When she was little, her mom 39 that even though she couldn’t see 40 , she was fearless. So her mom signed her up for gymnastics when she was three. She loved the 41 right away and gymnastics became her favorite.
Though learning gymnastics has been more 42 for her than for some of her tournaments, she has never quit. She doesn’t let her _43 stop her from doing anything that she wants to.
She likes the determination it takes to do the sport. Her biggest 44_ is the balance beam. Because she has double vision, she often sees two beams. She must use her sense of touch to help her during her routine. Sometimes she even closes her eyes. “You have to 45_ your mind that it’ll take you where you want to go,” says Lola.
To be a top-level gymnast, one must be brave. The beam is probably the most 46 for anyone because it’s four inches wide. At the state competition, Lola didn’t fall 47 the beam. In fact, she got an 8.1 out of 10---- her highest score yet.
Lola doesn’t want to be 48 differently from the other girls on her team. At the competitions, the judges don’t know about her vision _49 _. She doesn’t tell them, because she doesn’t think they need to know. Her mom is amazed by her _50 attitude.
Lola never thinks about 51__. She is presently at level 7 while the highest is level 10 in gymnastics. Her 52 is to reach level 9. She says she wants to be a gymnastics coach to pass down what she’s learned to other kids 53 she grew up.
Lola is 54 of all her hard work and success. She says it’s helped her overcome problems in her life outside gymnastics, too. Her 55 for others is “just believe yourself”.
