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.
【小題1】What does the passage say about asteroids and meteoroids?

A．They are heavenly bodies different in composition.
B．They are heavenly bodies similar in nature.
C．There are more asteroids than meteoroids.
D．Asteroids are more mysterious than meteoroids.
【小題2】 What do scientists say about the collision of an asteroid with Earth?
A．It is very unlikely but the danger exists.
B．Such a collision might occur once every 25 years.
C．Collisions of smaller asteroids with Earth occur more often than expected.
D．It's still too early to say whether such a collision might occur.
【小題3】 What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?
A．It sounds practical but it may not solve the problem.
B．It may create more problems than it might solve.
C．It is a waste of money because a collision of asteroids with Earth is very unlikely.
D．Further research should be done before it is proved applicable.
【小題4】We can conclude from the passage that ________ .
A．while pushing asteroids off course nuclear weapons would destroy the world
B．a(chǎn)steroids racing across the night sky are likely to hit Earth in the near future
C．the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetime
D．workable solutions still have to be found to prevent a collision of asteroids with Earth.
【小題5】Which of the following best describes the author's tone in this passage?
A．Optimistic.B．Critical.C．Objective.D．Subjective.

第二節(jié):讀寫任務(wù)

請根據(jù)以下任務(wù)說明和寫作要求,寫一篇幅150詞左右的英文短文。

Teenagers’ secrets should be kept to themselves and no one else ,their parents included, has the right to stick their nose into their private life. As we know, teenagers are going through a special period of development both physically and psychologically. They are curious about and puzzled by the unexpected changes in their body and mind. What’s more, exposed to a world of adults, it is only too natural for them to begin imitating (模仿) adults’ behaviors in secret. Boys begin to smoke and girls begin to spend time doing their hair. Some even begin to date with a girlfriend or boyfriend without their parents’ knowledge. They are doing al this in secret because they are still unsure whether it is right to do so and afraid that ,if found out by their parent, they will get misunderstood and even punished. And in fact, in many cases, the parents can not deal with the matter well and hurt their children’s feelings badly, making children no longer willing to communicate with their parents. When this happens, it hurts terribly the whole family feeling. So it seems right that teenagers should keep their secrets to themselves and their parents should allow their children that right.

科目：高中英語 來源：2013屆遼寧省東北育才學(xué)校高二上學(xué)期期中考試英語題 題型：閱讀理解

Most recently, it's very common in students that they need a parent present for job interviews．     

Naturally, it's easy to blame the students in these situations, but the bigger problem is us．We—as parents—are so eager to shelter our kids that we fail to realize that this in itself is harming them．As the mother of two young sons, I have to remind myself constantly that the biggest responsibility I have as a parent is to help them develop the skills needed to live without me．So, I'll let them fail．

    I'll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow．Although failure comes along with loss, heartbreak, disappointment, etc, these will be part of growth for them．And leaving them alone is my way of helping them become equipped to fit in this world as we know it today．From terrorism and seemingly endless natural disasters, to our national debt and beyond, if we expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and start teaching them how to fish．

    My children now are becoming little masters of compromise(妥協(xié)），but they try to negotiate （協(xié)商） everything now．It's a small price to help them learn a skill they'll use for the rest of their lives, including when I don't accompany them on job interviews．

1.Why do parents accompany their kids on job interviews?

    A．Because they want to protect their kids from difficulties．

    B．Because they think they can help them on the questions．

    C．Because their kids are too shy to attend interviews．

    D．Because their kids strongly request them to do so．

2.According to the author, what is beneficial to kids' development?

    A．Sheltering them．                     B．Keeping them safe．

    C．Leaving them alone．                  C．Blaming them．

3.Why does the author stress failure in kids' life?

    A．To make them stronger than other kids．

    B．To help them grow in this tough world．

    C．To help them develop all social skills．

    D．To make them learn to compromise．

4.Which of the following might be the best title for the text?

    A．Never Shelter Your Kids                B．Let Your Kids Fail

    C．Be Eager to Grow Up                  D．Live Without Parents
