Mobile phones help us easily find people anywhere at any time. A mobile phone can include many things, such as games, music and Internet access(»¥ÁªÍø½ÓÈë). Today, 4.6 billion people around the world have mobile phones, according to CBS News.

However, mobile phones may cause cancer, according to the World Health Organization. In a 2010 study, people who used a mobile phone for 10 years or more were more than two times as likely to get brain cancer, according to CNN.

¡°I think it is a good idea to give the public some kind of warning that long-term exposure(±©Â¶) to radiation (·øÉä) from your mobile phone could possibly cause cancer,¡±told Dr Henry Lai. Lai is a scientist of bioengineering(ÉúÎ﹤³Ì) at the University(´óѧ) of Washington who has studied radiation for more than 30 years.

These suggestions may help you reduce your risk of cancer:

1. Use a headset(¶ú»ú) or speaker

Headsets give out much less radiation than phones. Some headsets give out low-level radiation. However, you should take it off your ear when you¡¯re not talking to anyone. Using your phone with a speaker will also make it safer.

2. Listen more, talk less

Your phone gives out radiation when you talk or text, but not when you¡¯re listening or getting messages. Listening more and talking less can lower the risk of cancer.

3. Hold the phone away from your body

Hold the phone away from your body when you¡¯re talking, not against your ear. Also, don¡¯t keep it in your pocket.

4. Choose texting over talking

Phones give out less radiation to send texts than to carry a person¡¯s voice. Texting also keeps radiation away from your head.

5. Poor signal? Stay off the phone

A poor signal means that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.

1.The study from 2010 showed that _________.

A. people should use mobile phones for no more than 10 years

B. people who don¡¯t use mobile phones will not get brain cancer

C. the longer people use mobile phones, the more likely they are to get brain cancer

D. the more mobile phones people have, the more likely they are to get brain cancer

2.Which is NOT true about the suggestions mentioned in the passage?

A. Some headsets don¡¯t give out radiation.

B. It¡¯s not good to carry mobile phones in pockets.

C. Texting is better than making phone calls.

D. Don¡¯t make calls when the signal is weak.

3.The passage mainly talks about _________.

A. the development and advantages of mobile phones

B. the reason why mobile phone radiation causes cancer

C. the best ways to use mobile phones to communicate

D. how to protect ourselves from mobile phone radiation

LONDON¡ªScientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is to send a few comets (åçÐÇ) in the direction of Earth, and its orbit (¹ìµÀ)will be changed. Our world will then be sent moving into a safer older part of the solar system.

This idea for improving our climate comes from a group of US NASA (ÃÀ¹úº½¿Õº½Ìì¾Ö) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet¡ªhopefully doubling its working life.

The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid (СÐÐÐÇ) so that it passes close by our planet and sends some of its gravitational energy (ÖØÁ¦ÊÆÄÜ) 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(ľÐÇ) or Saturn (ÍÁÐÇ). 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 worldwide warming, although the team was actually worried about a much greater danger. The sun is certain to heat up in about a billion years and so ¡°seriously compromise¡± our biosphere (ÉúÎïȦ)¡ªby cooking us.

That¡¯s why the group decided to try to save Earth.

The plan has one or two worrying sides, 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 (ÎóËã)in orbit could fire it straight at Earth¡ªwith deadly results.

There is also the question of the moon. As the present issue of Scientific American magazine points out, if Earth was pushed out of its present location, it is ¡°most likely the moon would be stripped (°þÀë)away from Earth,¡± it states. This would greatly change our planet¡¯s climate.

1. 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.

2. 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

3.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 die because of the coldness.

C. The comet might hit Jupiter or Saturn and never return to Earth.

D. Earth¡¯s working life might be greatly shortened.

4.What does the underlined word ¡°compromise¡± mean?

A.provide B. benefit (ÊÕÒæ)

C. share D. Endanger
