Cellphones: is there a cancer link?
Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病學(xué)) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs(電磁場) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.
【小題1】From the passage we can learn that some people are worried because   .

A.they have evidence the use of cellphone can lead to cancer.
B.they make a fuss over cellphone use.
C.some expert has given a warning.
D.cellphones are responsible for brain tumors.
【小題2】By saying “I don’t support warning labels for cellphones,” Dr Martha Linet has the idea that   .
A.the worrying is unnecessary.
B.cancer-warning labels should be on cellphones.
C.there is a link between cellphones and cancer.
D.cellphones have nothing to do with cancer.
【小題3】The underlined word “underway” is closest in meaning to   .
A.started.B.kept on.C.gone on.D.in progress.
【小題4】Which of the following best describes the attitude of the author towards the debate?
A.Optimistic.B.Objective.C.Disapproving.D.Casual.

The Chinese word “Shanzhai” means a small mountain village, but now it becomes an accepted name for fakes (假貨) after “Shanzhai Cellphones” produced by small workshops in southern China became popular in the mainland market over the past two years.

       Besides “Shanzhai” has electronic products, there are “Shanzhai” movies, “Shanzhai” stars and even a “Shanzhai” Spring Festival Gala, a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year’s Eve.

       “Shanzhai” has become a culture of its own, symbolizing anything that imitates something famous.The phenomenon has caused a public debate over whether it is healthy or sick being a copycat.

       In southwestern China’s Chongqing Municipality, a “Shanzhai” version “Bird’s Nest” woven by farmers with bamboo attracts wide attention and the “Shanzhai” version “Water Cube” is popular with tourists too.Both are copies of the famous Olympics buildings in Beijing.

       Xie Xizhang, a literature critic, said that taking the “Shanzhai” Gala as an example, when the traditional CCTV program becomes less and less attractive to the audience, the “Shanzhai” version appears naturally to attract people.“In spite of its poor techniques and operation, ‘Shanzhai’culture meets the psychological demands of common people and could be a comfort to their minds,” Xie said.

       Tian Huiqun, a professor at Beijing Normal University, said that “Shanzhai” culture never copies classic things, only trendy products.In that sense, it’s like a computer virus, multiplying without meaning.

       Though controversial, “Shanzhai” culture is becoming a widely accepted phenomenon.

       To the mainstream culture, the rise of “Shanzhai” culture is a challenge as well as a motivation, said Xie.Tian said different kinds of cultures developing together is an ideal situation and it is for the public to choose.

The Chinese Word“Shanzhai”may have its origin in _________.

       A.fake cellphones           B.electronic products

       C.Spring Festival Gala     D.Olympics buildings

The underlined word “imitates” is closest in meaning to _______.

       A.steals               B.copies              C.a(chǎn)dvertises       D.cheats

According to the passage, “Shanzhai” culture refers to ________.

       A.The action that a person imitates famous people

       B.a(chǎn)nything that imitates something famous

       C.those similar names to famous brand

       D.products with poor techniques and quality

We can infer that the mainstream culture ________.

       A.will be held back by “Shanzhai” culture

       B.will sooner or later be replaced by “Shanzhai”culture

       C.may develop faster because of the challenging of “Shanzhai”culture

       D.thinks nothing of the challenge of “Shanzhai”culture

Dear iPhone 4 Users,
The iPhone 4 has been the most successful product in Apple’s history. It is the best smartphone ever, and most users have told that they love it. So we were surprised when reading reports of reception (信號接收) problems, and we immediately began researching them.
To start with, holding tightly(緊緊地)almost any mobile phone in certain ways will reduce its reception by 1 or more bars of signal strength. This is true of iPhone 4, iPhone 3GS, as well as many other phones. But some users have reported that iPhone 4 can drop 4 or 5 bars when tightly held in a way. This is a far bigger drop than normal, and as a result some have said the iPhone 4 has a faulty antenna(天線) design.
Upon research, we find that the formula(公式) we use to calculate how many bars of signal strength to display is totally wrong. Our formula usually mistakenly displays 2 more bars than it should for a given signal strength. The big drop in bars is because the high bars were never real in the beginning.
We will give a free software update to correct the formula. This software update (軟件升級)will also be available for iPhone 3GS. If you are not fully satisfied, you can return your undamaged iPhone to any Apple Retail Store or the online Apple Store within 30 days of buying and get all your money back.
Thank you for your patience and support.

There is a famous story about British poet Samuel Taylor Coleridge. He was writing a poem when he was interrupted by a knock at the door.
This was an age before telephones. Someone was delivering a message. When Coleridge got back to his poem, he had lost his inspiration. His poetic mood had been broken by the knock on his door. His unfinished poem, which could otherwise have been a masterpiece, would now never be more than a fragment (片段).
This story tells how unexpected communication can destroy an important thought,which brings us to the cellphone.
The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s disruption (中斷) of our thoughts.
We have already entered a golden age of little white lies about our cellphones, and this is by and large a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.
The notion of being unreachable is not a new concept – we have “Do Not Disturb” signs on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?
The problem is that we come from a long-established tradition of difficulty with distance communication. Until the recent mass deployment (使用) of cellphones, it was easy to communicate with someone next to us or a few feet away, but difficult with someone across town, the country or the globe. We came to take it for granted.
But cellphones make long-distance communication common, and endanger our time by ourselves. Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees, myself usually included, can’t help at times wanting to throw their phone away, or curse the day they were invented.
But we don’t and won’t, and there really is no need. All that’s required to take back our private time is a general social recognition that we have the right to it. In other words, we have to develop a healthy contempt (輕視) for the rings of our own phones. Given the ease of making and receiving cellphone calls, if we don’t talk to the caller right now, we surely will shortly later.
A cellphone call deserves no greater priority (優(yōu)先考慮的事) than a random (隨機(jī)的) word from the person next to us. Though the call on my cellphone may be the one–in–a–million from Steven Spielberg–who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.
【小題1】What is the point of the anecdote(軼事,趣聞) about the poet Coleridge in the first three paragraphs?

A.To direct readers’ attention to the main topic.
B.To show how important inspiration is to a poet.
C.To emphasize the disadvantage of not having a cellphone.
D.To encourage readers to read the works of this poet.
【小題2】What does the writer think about people telling “white lies” about their cellphones?
A.It is a way of signaling that you don’t like the caller.
B.It is natural to tell lies about small things.
C.It is basically a good way to protect one’s privacy.
D.We should feel guilty when we can’t tell the truth.
【小題3】According to the author, what is the most annoying problem caused by cellphones?
A.People get annoyed by the cellphone rings that they fail to notice anything else.
B.People feel guilty when they are not able to answer their cellphones.
C.Cellphones interrupt people’s private time.
D.With cellphones it is no longer possible to be unreachable.
【小題4】What does the last paragraph suggest?
A.A person who calls us from afar deserves more of our attention.
B.Steven Spielberg once called the author to talk about the author’s novel.
C.You should always finish your lunch before you answer a call on the cellphone.
D.Never let cellphones interfere too much with your life.
