“Mobile phones killed our man,”screamed one headline last year.Also came statements that an unpublished study had found that mobile phones cause memory loss.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 moblie 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 device(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 suggestion that mobile phones have an immediate effect on our cognitive(感知的) abilities.“I’m pretty sure there is no effect on 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 William 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 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 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 Preece 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. consensusB. disagreementC. possibilityD. 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 to develop brain tumours

C. is unlikely to develop brain tumours

D. will cause your loss of memory for ever

Given the tradition of students bringing apples to their teachers, it somehow seems fitting that an old apple barn(谷仓)will find a new life as a one-room schoolhouse. And it is just as fitting that a retired schoolteacher will become the caretaker of that historic treasure.

My friend Velma, a teacher for more than 30 years, has been retired for some time now, but that doesn’t stop her giving history lessons at the old Englewood School, located on her family’s

California farm. The lovingly restored building was constructed around 1850 as a home for a woodsman and later was used as apple barn. Then, in 1870 it began a new life as a schoolhouse.

Originally located in the nearby Englewood meadow, it was now moved its current site in 1978 by Velma’s late husband and his brother, Robert and Richard, who thought it would help keep

Velma busy in retirement. No nails had been used in the original construction, so each piece of wood had to be carefully marked and the building was reassembled(重装)on its new site. The brothers worked with much care and hard work to ensure a perfect fit of mitered(斜接的)corners.

After the relocation, Velma and her family furnished the school with some of its original desks. They also added a collection of schoolbooks, the oldest dating back to 1845. Perhaps the school’s most cherished souvenir is the diploma of student Hettie Essig, who graduated on June 30, 1904. Hettie’s daughter, Flora, presented Velma with the precious keepsake.

Nowadays Velma gives tours to local schoolchildren and other groups, who learn what it was like to attend school back in the good old days. She has kids ring the school bell, recite the Pledge of Allegiance and sing “Good Morning to You” as they might have done in days gone by. Then, with twinkling eyes and much enthusiasm, she tells the history of the school, and gives a short sample lesson.

1.The Englewood School was originally built as __________.

A. a man’ s house B. a schoolhouse

C. a restroom D. an apple barn

2.Which word can best describe the school’s being relocated?

A. Inspiring B. Refreshing

3.What does the underlined part “the precious keepsake” in Para.4 mean?

A. The school’s original supplies

B. The collection of schoolbooks

C. The oldest schoolbook

D. The diploma of Hettie Essig.

4.Which can serve as the best title of the passage?

A. The Good Old Days in the Schoolhouse

B. A Mysterious Building with a Long History

C. A Historic One-room Schoolhouse

D. A Teacher Devoted to Restoring Old Buildings
