Move Earth—it’s no science fiction
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets(彗星)in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams is designed to carefully direct a comet or asteroid(小行星) so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere(生物圈)by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation(误算)in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped(剥去) away from Earth,” it states. This would greatly change our planet’s climate.
32. What makes the scientists plan to move Earth?
A. A few comets are moving to the direction of Earth.
B. Earth’s working life is coming to an end soon.
C. Earth will become too hot for mankind to keep alive.
D. The moon is moving farther and farther away from Earth.
33. If the plan is successful, Earth will have a working life of ______ years.
A.12 billion B.6 billion C.18 billion D.24 billion
34. What serious problems might the plan cause according to the passage?
A. The comet might hit Earth and man might lose the moon.
B. Earth might be moved too far away and man might be frozen to death.
C. The comet might hit Jupiter or Saturn and never return to Earth.
D. Earth’s working life might be greatly shortened.
35. What does the underlined word “compromise” mean?
A. provide B. benefit C. share D. endanger

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。
Happy birthday! Do birthdays really makes people happy? 36 Birthdays celebrates the day when we were born. Besides, that extra candle on the cake suggest another year of growth and maturity(成熟)—or so we hope.We all like to imagine that we are getting wiser and not just older.Most of us enjoy seeing the wonder of growth in others, as well.For instance, seeing our children develop and learn new things makes us feel proud.For Americans, like people in most cultures, growing up is a wonderful process.But growing old?
37
Growing old is not exactly for people in youth-oriented(以年轻人为中心)American culture. 38 As the old saying goes, “You’re young as you feel.” Older people joke about how many years young they are, rather than how many years old.People in some countries value the aged as a source of experience and wisdom.But Americans seem to favor those that are young, or at least “young at heart”.
Many older Americans find the “golden years” to be anything but golden.Economically, “senior citizens” often struggle just to get by.Retirement at the age of 65 brings a sharp decrease in personal income.Social security benefits usually cannot make up the difference.Older people may suffer from poor nutrition, medical care, and housing. 39 American sociologist Pat Moore once dressed up like an older person and wandered city streets.She was often treated rudely--even cheated and robbed.However, dressed as a young person, she received much more respect.
40 Why? People are living longer.Fewer babies are being born.And middle-aged “baby boomers” are rapidly entering the group of the elderly.America may soon be a place where wrinkles(皱纹)are “in”.Marketing experts are already noticing this growing group of consumers.
A.That is a different story.
B. Most people in America like the young.
C. Of course they do.
D. Some even experience age discrimination(歧视).
E. People in America grow larger every year.
F. Most Americans like to look young, act young and feel young.
G. Unfortunately, the elderly population in America is increasing fast.

Dear Tracy,
I want to make friends with those who have same interests, but I am continually disappointing. No one I know have the same interests as I. Mine include read books and newspapers, watching news programmes, listening music and so on. But my friends were only interested in talking about the best way to make lots of money and what they will buy with them. That you know, friends are very important, so I don’t know where and how to find the friends I want. Can you offer me some suggestion?
