“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.

     For anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.

     One of the oddest effects comes from the now famous “memory loss” study. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were 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 suggestion that mobile phones have an immediate effect on our cognitive（認(rèn)識(shí)的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.

     Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses（神經(jīng)元突觸） exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.

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

“If it doesn’t certainly 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 use does damage your memories or give you cancer, the conclusion is: don’t be afraid.

Mobile phone users are worried because ______.

A. they are not sure whether mobile phones can cause memory loss

B. it’s said that mobile phones have a lot of side effects

C. one headline reported “Mobile phone killed my man”

D. a British newspaper showed mobile phones could heat the brain

According to this passage, we can know that _____.

A. the mobile phone is a most wonderful invention

B. there’s no need to worry about the radiation from mobile phones

C. something must be done to stop people using mobile phones

D. mobile phone companies shouldn’t cheat customers

科目：高中英語 來源：20102011安徽泗縣雙語中學(xué)高一下學(xué)期第二次月考英語試題 題型：填空題

Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here’s how.

1) Plan your time carefully. When you plan your week, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don't forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

2) Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television! When you sit down to study, concentrate on the subject.

3) Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what the teacher says.

4) Study regularly. When you get home from school, go over your notes. Review the important points that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read that material will become more meaningful, and you will remember it longer. w.w.w.zxxk.c.o.m

5) Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don't pass a test, so don't be overly worried.

There are other methods that might help you with your studying. You will probably discover many others after you have tried these.
