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.

While attending a conference, I returned to my hotel room late one rainy evening．The overhead light outside my door was 36 and I had difficulty finding the keyhole．When I finally 37 to open the door, I 38 around the wall for a light switch．I found a 39 where a switch was once installed… but no switch．
No discouraged easily, I remembered seeing a 40 by the bed when I put away my luggage 41 in the day．I found the bed in the dark and felt around until I found the lamp, but when I switched it on, 42 happened! Now what?
Though I knew that it was dark outside my window 43 the outdoor light was burned out, I thought that 44 if I opened the curtains I might be able to use the light from the 45 to find another lamp．So I 46 my way slowly across the room to the curtains and… no draw-string!
I finally stumbled（跌跌撞撞） around until I found a desk lamp that actually 47 ! That evening I discovered in a whole new way just how dark the world can be and how necessary 48 is．
But even more necessary than 49 light is the light that shines from people — the light of love, sympathy and 50 ．Because, for many people, the world is a dark and 51 place．
It is the shining that is important, for someone today just may be stumbling in discouragement or fear and in 52 of some light．
So let your light shine．Whatever light you 53 may be a beacon（灯塔）of hope and encouragement in someone’s darkness．And if you feel that your light is 54 a candle in a forest, remember this — there isn’t enough darkness in the world to 55 the light of one small candle．

It is the season for long lines and frayed (紧张的) nerves. Here’s how to deal.
Lighten up
Do youreslf a favor and ship(运送) your presents. Nearly every U.S. airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.
Weigh your options
Now knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.
Leave amateurs（不熟练者） in the dust
Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced fliers, and it’s a hard walking. Plus, if you decide to cut it close, you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.
Take it public
The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories(地产) have increased dramatically. True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.
Say no to bumper cars
Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX, now feature this sensible choice.
68.Airlines have reduced flights to_________.
A. deal with crisis B. reduce the time for leave
C. lower the cost D. provide more job chances
69. We can learn from the passage that____ .
A. taking a taxi at the airport is expensive
B. taxis stay at the airport free of charge
C. cars can park at the airport for free
D. JFK encourages people to take a taxi
70. What’s the best title for the passage?
A. 5 Ways to Survey a Holiday Flight. B. Good Seasons for Flight
C. Cars at the Airport D. How to Board a Flight
