Unless we spend money to spot and prevent asteroids now,one might crash into Earth 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 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 it 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 big 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(毀滅性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.

Sunday is more like Monday than it used to be. Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant (不相關(guān)的). A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear.
The law in almost all states used to require stores to close on Sunday; in most, it no longer does. It used to keep the schools open in all seasons except summer; in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other?
These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “l(fā)aw of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years—but unless we meet the truant officer (學(xué)監(jiān)), we may well think that we should go to school due to social custom and parents’ demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes (構(gòu)成)“overtime” is a matter of legal definition. When we turn the clock forward to start daylight-saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how we organize and use time: compulsory education law, overtime law, and daylight-saving law — as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess.
【小題1】By saying “Sunday is more like Monday than it used to be”, the writer means that_____ .
A.work time is equal to rest time |
B.many people have a day off on Monday |
C.it is hard for people to decide when to rest |
D.the line between work time and rest time is unclear |
A.fail to make full use of their time | B.enjoy working overtime for extra pay |
C.a(chǎn)re unaware of the law of time | D.welcome flexible working hours |
A.need to acquire knowledge | B.have to obey their parents |
C.need to find companions | D.have to observe the law |
A.Our life is governed by the law of time. |
B.How to organize time is not worth debating. |
C.New ways of using time change our society. |
D.Our time schedule is decided by social customs. |

Dear Editor.
I’m a middle school student named Li Hua. I’m writing tell you something. Recently I noticed that many of my schoolmates often go to the Internet bar near our school. The other day, I went there, either.I was surprising to see many students playing computer games, seeing movies or were chatting. Some students were even sending love letter online. In my opinion, Internet bar should be a place which we can find much usefully information. Internet should be a window to the outside world rather than a place for playing games. Internet is good unless we make good use of it. Otherwise, they will do us great harm. So the local government should take measures to make sure of the “safety” of students in the Internet bars.

Recently I gave my adult students homework. It was “go to someone you love and tell them you love them.” It has to be someone you have never said those words to before or at least haven’t shared those words with for a long time.
It sounds like very tough homework since most of the men were over 35 and were raised in the generation of men that were taught expressing emotions is not “macho (陽剛之氣).” Showing feelings or crying was just not done. So this was very threatening homework for some.
At the beginning of our next class, I asked if someone wanted to share what happened when they told someone they loved them. I fully expected one of the women to volunteer, as was usually the case, but on this evening one of the men raised his hand, quite moved and a bit shaken.
As he unfolded out of his chair (all 1.85 meters of him), he began by saying, “Dennis, I was quite angry with you last week when you gave us this homework. Who were you to tell me to do something that personal?”
“But as I began driving home my conscience (良心)started telling me that I knew exactly who I needed to say ‘I love you’ to.”
“Five years ago, my father and I had a severe disagreement and really never settled it since then. We avoided seeing each other unless we absolutely had to at Christmas or other family gatherings. But even then, we hardly spoke to each other.”
“So last Tuesday by the time I got home I had convinced myself. I was going to tell my father I loved him. It’s strange, but just making that decision seemed to lift a heavy load off my chest.”
1. The homework is threatening for some students because_________.
A. they are middle-aged people B. they are not macho enough
C. they were taught to hide their emotions D. they didn’t know how to show feelings
2. From the passage we know that_________.
A. the adult students have classes in the day time only
B. not all the adult students in the writer’s class are male
C. the man refused to meet his father after their quarrel
D. the man quickly decided to say “I love you” to his father
3. The underlined phrase “unfolded out of his chair” in Para 4 is closest in meaning to_________.
A. stood on his chair straight B. sat quietly in the chair
C. bent himself over his chair D. raised himself slowly from the chair
4. What does the man imply by saying the underlined sentence in the last paragraph?
A. He felt it too strange to say “I love you” to his father.
B. He felt relaxed just thinking of saying “I love you” to his father.
C. He felt very relaxed after saying “I love you” to his father.
D. He had to lift a heavy load off his chest before saying “I love you”.
