Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone makers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters.
If health issues arise from cell phone use, the possible effects are huge. According to Devra Davis, an expert who has worked for the University of Pittsburgh, brain cancer is a concern. Over all, there has not been an increase in its occurrence since cell phones arrived. But the average masks an increase in brain cancer in the 20-29 age group and a drop for the older population.
“Most cancers have many causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates (穿透) only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls (頭骨) are thinner and their brains contain more absorptive fluid.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the belly.
1.According to Ms Davis, brain cancer increases ________.
A. in the teenagers B. among old people
C. in the twenties D. among pregnant women
2.What does the underlined word “vulnerable” in the 4th paragraph probably mean?
A. accessible B. changeable
C. passive D. sensitive
3. The author’s purpose of writing the text is most likely to ________.
A. entertain B. persuade
C. describe D. inform
4.Which of the following would be the best title for the passage?
A. Low-energy Radiation Leads to Cancer
B. Cell Phone Use Brings Health Problems
C. Radiation Damages DNA in People’s Brain
D. Researchers Launched Lab Studies on Cell Phones

Many people write to newspaper and magazines to express their opinions. Letters to the editor must carry the writer’s full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are held responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. Responsibility is the name of the game.
“People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer’s signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.
There are people who wish to remain anonymous(匿名的) for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he does not want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.
Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter of responsibility to use it when we make a statement, a claim or an accusation. We all want to honor our own name, and it is only by stamping our expression of an opinion with our own name that we honor what we say.
1.What does the writer mean by saying “Responsibility is the name of the game”?
A. Writers need to provide their personal information in the game.
B. Publication must bear the writer’s full name, address and phone number.
C. Writers should be responsible for their names.
D. Names are required to indicate writers’ responsibility for what they say.
2.The second paragraph suggests that a paper without a signature may ________.
A. not get a replyB. help to end a relationship
C. be accepted all the sameD. become a family problem
3.Some people don’t want their names known because they are ________.
A. hesitant to make a donationB. unwilling to draw public attention
C. afraid of an accusationD. ready for involvement
4.The passage is mainly about ________.
A. honor and writers
B. identity and signature
C. signature and responsibility
D. anonymity and signature

We know that hugs make us feel cosy inside. And this feeling could actually ward off stress and protect the immune (免疫) system, according to a new research from Carnegie Mellon University.
It’s a well-known fact that stress can weaken the immune system. In this study, the researchers sought to determine whether hugs could protect individuals from the increased sensitivity to illness brought on by the particular stress that comes with interpersonal conflict.
“We know that people experiencing ongoing conflicts with others are less able to fight off cold viruses. We also know that people who report having social support are partly protected from the effects of stress on psychological states, such as depression and anxiety, ” the study’s lead author, psychologist Dr. Sheldon Cohen , said in a statement. “We have tested whether awareness of social support is equally effective in protecting us from sensitivity to infection caused by stress and also whether receiving hugs might partially account for those feelings of support and thus protect a person against infection.”
In the experiment, over 400 healthy adults filled out a questionnaire about their perceived (感知到的) social support and also participated in a nightly phone interview for two weeks. They were asked about the frequency that they engaged in interpersonal conflict and received hugs that day.
Then, the researchers exposed the participants to a common cold virus, and monitored them to assess signs of infection. They found that both perceived social support and more frequent hugs reduced the risk of infection associated with experiencing interpersonal conflict. Regardless of whether or not they experienced social conflicts, infected participants with greater perceived social support and more frequent hugs had less severe illness symptoms.
“This suggests that being hugged by a trusted person may act as an effective means of conveying support and that increasing the frequency of hugs might be an effective means of reducing the effects of stress,” Cohen said. “The apparent protective effect of hugs may result from the physical contact itself or hugging being a behavioral indicator of support and closeness. Either way, those who receive more hugs are somewhat more protected from infection.”
If you need any more reason to wrap your arms around someone special, consider this: hugs also lower blood pressure, reduce fears, improve heart health and decrease feelings of loneliness.
1.In Paragraph 1, the underlined words “ward off “can be replaced by ____.
A. produce B. increase C. prevent D. support
2.Dr. Sheldon Cohen’s experiment shows that ____.
A. hugs can hide serious illness symptoms
B. social conflicts can monitor signs of infection
C. social support can reduce the risk of having a cold
D. depression and anxiety result from less social support
3.The passage aims to convey that ____.
A. hugs can have protective effects
B. social support can cure diseases
C. interpersonal conflicts cause infections
D. stress can weaken our immune system
4.The passage is most likely to be found in ____.
A. a social science magazine
B. a commercial brochure
C. a medical report
D. an academic essay

Are you looking for something to do? You might like to try one of these four experiences.
Crocodile watching
Do you fancy getting up close to some of the most terrifying animals on earth? Crocosaurus Cove, in Darwin (Australia) has the “Cage of Death”. It’s an enclosure(圍場(chǎng)) that’s lowered into a pool. This gives you a 360 degree view of a crocodile as it’s being fed. The cable broke once and the cage sank to the bottom, but they’ve fixed it since then.
Edge walk
How about walking along the edge of a building several hundred meters up in the air? If that sounds like fun, head off to the CN Tower in Toronto (Ontario, Canada). Built in 1976, the tower is 553.33 meters tall.
The Edge walk consists of a 20-30 minute stroll along a 1.5 meter wide platform that runs around the tower’s restaurant roof. During the walk, you’re encouraged to lean forwards as you look over Toronto’s skyline (輪廓線).
Plastic ball rolling
Do you fancy rolling down a hill in a plastic ball?
Plastic ball rolling is popular all over the world, but the place to give it a go is in Rotorua (New Zealand). Brother David and Andrew Akers came up with the idea in 1994. A typical orb (球) is about 3 meters in diameter, with an inner orb size of about 2 meters. There’s no brake or steering mechanism, but the inner layer of the plastic ball helps absorb the shock.
Volcano bungee jumping
If you’re looking for the adventure of a lifetime, how about going bungee jumping off a helicopter into the crater of a live volcano? As part of the jumping, a helicopter ride takes you to the Villarreal volcano, one of the most active in Chile. Once you’re at the drop zone, you leap off the helicopter and fall into the volcano. Finally, you enjoy the ride back to the airport flying at 130kph.
