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(流行病学) 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(电磁场) 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.

In choosing a friend, one should be very careful. A good friend can help you study. But how do I know when I have found a good friend? I think a good friend should have certain good qualities(品质), especially understanding, honesty and reliability(可靠).
Above all , I look for understanding in a friend. A good friend tries to understand how another person is feeling. He puts himself in the other person’s place, and he tries to think of ways to be helpful. He is also a good listener.
At the same time, however, a good friend is honest. He does not look for faults in others. He notices their good points. In short, a friend will try to understand me and accept me.
Sometimes you will meet “fair weather friends”. They will be with you as long as you have money or luck, but when you are down, they will run away. So, I think another quality of a friend is reliability. I can always depend on a good friend. If he is in trouble, I will do my best to help him. If I need a favor, he will not run away from me.
When I meet someone who is reliable, honest, and understanding, I know I’ve found a friend!
58. According to the writer, what good qualities should a good friend have? (回答词数不超过5个)
59. What will you do when your good friend is in trouble? (回答词数不超过8个)
60. What is the meaning of understanding in a friend according to the writer’s opinion? (回答词数不超过18个)
A Nobel Prize is considered by most people one of the highest international honors a person can receive. As you know, the prizes were started by a Sweden called Sweden Alfred Nobel. Alfred Nobel was born in Stockholm, the capital of Sweden, and lived from 1833 to 1896.
Alfred Nobel was a chemist and inventor. He made two important inventions, so he became very rich. Although he was rich, Nobel was not a happy man. He never married or had children. Also, he was a sick man in large part of his life. Nobel died at the age of sixty-three. When he died, he left a fund of $9,000,000. The money was to be used in giving prizes to those who made outstanding achievement in physics, chemistry, medicine, literature, and the promotion(促进)of the world peace.
The first Nobel Prize were given on December 10th,1901, five years after Nobel’s death. Many famous people all over the world have been given Nobel Prizes for their achievements. Albert Einstein was one of them.
Each prize has three parts. The first part is a gold medal. Second, a winner of a Nobel Prize is given a diploma saying that he has been given the prize. The third part of the prize is a large amount of money---about $40,000.
Often a prize is given to just one person, but not always. Sometimes a prize is shared. It might be given to two or more people who have worked together. It is also sometimes true that a prize is not given at all if there is no outstanding achievement. In 1972, for example, not a Nobel Prize was given. It is the Nobel Foundation in Stockholm that decides whether to give the prize or not.
小题1:Most people think that Nobel Prize is ____ a person can receive.
A.the highest honor in the world |

What is your favorite color? Do you like yellow, orange, and red? If you do, you must be an optimist(乐观者), a leader, an active person who enjoys life, people and excitement. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference(爱好), and the effect that colors have on human beings. They tell us that we don"t choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing(压抑). Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.
Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don"t forget that anyone can guess a lot about your character when you choose a piece of handkerchief.

A 7.0 magnitude(级)earthquake killed more than 230,000 people in Haiti. Then an 8.8 magnitude quake killed more than 900 people in Chile. And few weeks later, a 6.0 magnitude quake struck rural eastern Turkey, killing at least 57 people.
The earthquakes kept coming hard and fast. 1 It’s not. The problem is what’s happening above ground, not underground, experts say.
2 They’re rapidly putting up buildings that can’t stand up to earth quakes, scientists believe.
And news reports and better earthquake monitoring make it seem as if earth quakes are increasing all the time.
On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9. So far this year there have been 40 earthquakes—more than in most years for that time period. But that’s because the 8.8 quake in Chile caused a large number of strong aftershocks.
Also, it’s not the number of quakes, but their destructive effects that gain attention. The death is largely due to building standards, 3 Paul Earle, a US seismologist, called for better building standards in the world’s big cities.
Of the 130 cities worldwide with populations of more than I million, more than half are likely to be hit by earthquakes. 4 “If you have a problem feeding yourself, you’re not really going to worry about earthquakes,” said Paul.
The earthquakes made everyone start to think 5 “People are paying attention to the violent planet we’re always lived on. Come back an another six moths if there has been no earthquakes, most people will have forgotten it again,” said US disaster researcher Dennis Mileti.
A.But it won’t last. B.More people are moving into big cities. C.Earthquakes don’t kill people, buildings do. D.There have been more deaths overt the past decade from earthquakes. E.Many people began to wonder if something terrible is happening underground. F.While it seems as if the are more earthquakes occurring, there really aren’t. G.But developing nations with growing populations don’t pay attention to earthquake preparedness. |
