“Mobile phones killed our man.” screamed one headline last year. Also came statements that an unpublished study had found that mobile phones cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones heat the brain. For anyone who uses a mobile phone, these are worring times. But speak to the scientists whose work is the focus of these scared and you will hear a different story.

What we do have, however, are some results suggesting that mobile phones’ emission(辐射) have a variety of strange effects on living tissue that can’t be explained by the general radiation biology. And it’s only when the questions raised by these experiments are answered that we’ll be able to say for sure what mobile phones might be doing to the brain.

One of the strange effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a devic(装置) that copied the microwave emission of mobile phones to the left ear of volunteers. The volunteers were all good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggesting that mobile phones have an immediate effect on our cognitive(感知的) abilities. “I’m pretty sure there is no short-term memory.” he says.

Another expert, Tatterasll, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses(神经元突触) exposed to microwaves become more—rather than less—receptive to under-going changes linked to the memory formation.

It would be an even happier outcome if microwave turned out to be good for you. It sounds crazy, but a couple of years ago a team led by Willian Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwave for two hours a day were less likely to develop brain tumours(肿瘤) when given a cancer-causing chemical.

So should we forget about mobile phone radiation causing brain tumours and making us unable to think clearly or reasonably?

“If it doesn’t cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone does damage your memories or give your cancer, the unanimity is: Don’t panic.

1.What worries people who use mobile phones?

A. Mobile phones will kill them.

B. Mobile phones cause memory loss.

C. Mobile phones heat the brain.

D. All above is right.

2.What is the attitude of Prece on the suggestion that mobile phones have an immediate effect on our congnitive abilities?

A. Doubt.            B. Disagree.            C. Approve.            D. Wait and see.

3.The underlined word “unanimity ”in the last paragraph most probably means “_______”.

A. consensus        B. disagreement        C. possibility        D. impossibility

4.From the fifth paragraph, we can infer that being exposed to microwaves for two hours _________.

A. can result in killing you

B. is likely develop brain tumours

C. is unlikely to develop brain tumours

D. will cause your loss of memory for ever

Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are frequently blamed for a number of things, from thumb injuries and headaches to house fires. 1.

The theory is that the bees navigation (导航) systems are damaged by the radiation that is given off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home. 2.

The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated (授粉) by them. 3. Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, a London beekeeper, was recently asked how the problem was affecting him. “My business has been ruined by this,” he explained, “twenty-nine of my forty hives are now empty.”

4. However, the fact that bees are disappearing in very large numbers is real. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! 5. If the mobile phone theory is correct, we need to do something about it immediately—before it’s too late.

A. Bees are losing their way.

B. Nobody has proved the theory is true.

C. More evidence is provided to support the theory.

D. It is believed they are dying far from their hives.

E. Without bees, the crops can’t continue to grow.

F. The situation needs to be evaluated by the world’s best scientists.

G. One theory even blames mobile phones for the disappearance of bees.

I’m going through it right now. Last night one of our three family dogs was hit and killed by a car in front of my mother’s house. The dogs became, more or less, my mother’s surrogate children after her human children grew up and moved out and my father ran with a midlife crisis and left her. The one that was killed had bonded with my mother far more than the others.

She is extremely shocked. I loved the dog, but my true sadness currently results from having to watch my mother bear another tragedy after everything she has been through in her life. In the midst of all of this, I have to sincerely applaud the driver of the vehicle, which feels wrong, but it’s not.

I’ll start by stating it was not his fault. The dog ran after a deer into the road at night. In an effort not to hit the deer with his car, he changed direction, not seeing the dog, resulting in its death. He could have very easily continued on his way, but he did something that I hope I never forget.

In my eyes, he did the right thing. The driver pulled over, carefully wrapped our dog in a blanket he got from his car to preserve its dignity, and carried it up to my mother’s front door.

He was visibly shaking and very upset. He informed my mother of what happened and she broke down immediately. He comforted her the best a stranger could and waited with her while my sister rushed to her house. He left his information and offered assistance in any way he could.

Yes, he is the man who hit and killed our dog accidentally. What he really did was spare my mother, and potentially my sister, from coming across a horrible scene themselves while searching for the dog. He had so many choices that were far easier to make than what he chose. He did the right thing and for that, thank you, Stranger. You restored my faith in humanity.

1.What do we know about the dog killed by the driver?

A.It was killed by the driver on purpose.

B.It lost its life during a fight against a deer.

C.It was a particular favorite of the author’s mother.

D.It got killed by hitting the deer while running after it.

2.What does the underlined part “feels wrong, but it’s not” in Paragraph 2 probably mean？

A.The driver ought to answer for the dog’s death.

B.The author thought it sensible to praise the driver.

C.The author believed it was not the driver’s fault to kill the dog.

D.The driver should not take responsibility for the dog’s death at a11.

3.Which of the following can best describe the driver?

A.Self-condemned and considerate. B.Calm and far-sighted.

C.Reliable and generous. D.Irresponsible and unreasonable.

4.What may the author agree with?

A.Still waters have deep bottoms.

B.Those who are ready to believe are easy to cheat.

C.When the wound is healed，the pain is forgotten.

D.Taking responsibility is the best policy.

No Mobile Means You’re Not in Touch

My household now has four mobile phones: one for me; one each for my eldest children, the twin boys; and one for my 15-year-old daughter. Only my 12-year-old son does not (yet) have his own mobile. In other words, we’re now in line with national figures, which show that Australia has 19 million mobile phones for a population of just over 20 million people. Among 15-to 17-year-olds, nearly nine out of 10.

The reality is that a mobile phone is the coolest thing of all for a teenager to own. It’s even more important than a television, a DVD player or access to the internet. If you don’t have a mobile you are, quite literally, out of touch.

Of course, there are good and bad sides to mobiles. In my global media world, I’ve lived with a mobile switched on 24 hours a day, seven days a week, for the past ten years. At the same time, here in Perth, I started a movement on talkback radio called CAMPIR (Campaign Against Mobile Phones in Restaurants). Nothing annoys me more than people who feel that an incoming mobile call is more important than the company they are with at a restaurant or even at their dining table at home, but I believe that in the long term, we will have a revolt against the intrusion of mobiles into our personal lives.

There was a study in New Zealand last year among young teenagers that showed a quarter have used text messaging to end a relationship. Here in Australia, I’ve read of people being fired by text. That’s cold. On the other hand, lots of parents---myself included---feel their children are safer if they have their mobile with them when they are away from home.

I’ve even read that the use of mobiles among kids may mean that they smoke less. Phones are a stronger status symbol than cigarettes among children and also give them something to do with their hands.

Psychologists, though, argue that mobiles are actually a way for kids to bypass their parents. They can communicate constantly with their friends without their parents knowing anything of the conversations. No matter what the future brings, I don’t expect ever to have fewer mobiles in the house. On the contrary, the next challenge is to see if I can get through the rest of this year without having to buy a mobile phone for my youngest child.

1.According to the passage, a mobile phone is the coolest thing for a teenager to possess because _________.

A.In their opinion, the mobile phone is the most fashionable possession

B.A mobile phone is the most useful tool in the life.

C.The teenager keeps in contact with others exactly by using a mobile phone.

D.The Internet is less important than the mobile phone.

2.,Which of the following statements is true according to the passage?

A.In New Zealand most young teenagers have used text messaging to end a relationship.

B.The writer doesn’t think his children can avoid danger if they have their mobile with them .

C.The use of mobiles among kids may contribute to their less smoking.

D.Cigarettes are the strongest status symbol among children.

3.The underlined word “bypass” in the fifth paragraph probably means __________.

A. contact       B. avoid        C. inform        D. oppose

4.  It can be inferred from the passage that __________.

A. The children in the family each have a mobile phone.

B. About 60% of the children aged 15-17 have phones in Australia.

C. The writer is likely to buy a mobile phone for his youngest child this year.

D. The writer doesn’t agree that children should own a mobile phone.
