WARNING: Holding a cell phone against your ear or putting it in your pocket may be bad for your health.
This sentence is a warning that you’d better not put it close to you when a new phone is bought. Apple company, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.
If cell phone use can cause health problems, the result will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.
Devra Davis, an epidemiologist(皮肤病专家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation(辐射)"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase (增长) in brain cancer in the 20-to-29 age group and a drop for the older people.
Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.
Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency(电波频率)radiation had destroyed DNA in their brains.
Ms. Davis recommends using wired earphones(有线耳机)or the phone's speaker. Children should send text messages rather than call, she said, and pregnant women should keep phones away from their bodies.

Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students will be able to use e-mail to “speak” with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all!
Because of the many changes in computer technology , laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable( 便携式的) computers can connect students to not only the Internet, but also libraries and other resources(资源). State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too.
At Westlake College, more than 60 percent of the staff(职员) use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, “ Here we are in the middle of Virginia and we’re giving students a window on the world.

It was reported today that in China, 56% of people who write blogs(博客) do so as a personal diary and 83% use their blogs for sending messages to friends. It was also found that there is a strong East- West difference. In places like the US, blogs that offer information on news attract more readers but in China, blogs are more likely to be about sharing personal feelings.
It seems that bloggers can be divided into three types: IT bloggers, bloggers who record their ordinary feelings and media(媒体) bloggers.
When blogging first started, the IT people had the technological advantage and they took the chance to put their thoughts on the web. Some of these IT people now have had over a million people read their blogs.
The next wave of bloggers did not have any training as writers or in IT and wrote about normal daily life. Media bloggers, however, are trained writers, such as journalists and editors. When the many media bloggers showed up, the everyday bloggers lost most of their readers. Media bloggers have the advantage of knowing how to communicate well through the written words.
However, the normal bloggers are still out there and increasing in number. It seems that blogging is the new way to express your feelings. People feel like the world is listening to, or rather reading, their problems, even if they are not. From the passage we know that________.
A.56% of the Chinese write blogs |
B.people in US like to read blogs for news |
C.the Chinese never share feelings with each other through blogs |
D.the way that Chinese use blogs is not different from the West |
________wrote more blogs at the very beginning .
A.IT bloggers | B.Media bloggers |
C.Normal bloggers | D.US bloggers |
Which of the following is true according to the passage?
A.There will be more and more normal bloggers. |
B.Only bloggers express their feelings through the Internet. |
C.All people in the world are listening to the bloggers’ voice. |
D.Media bloggers didn’t have the advantage of knowing how to communicate well. |
The underlined expression in the passage can be best replaced by “________”.
A.increased. | B.appeared . |
C.arrived. | D.grew. |
A ship met a storm at sea and only two of the men were able to swim to a small, deserted island. Not knowing what else to do, they agreed to pray(祈祷) to God on opposite sides of the island.
Of course, the first thing they prayed for was food. The next morning, the first man saw a fruit tree on his side. But there was nothing on the other man’s side.
Later the first man prayed for a house, clothes and more food. The next day, all of these things were given to him. However, the second man still had nothing.
Finally, the first man prayed for a ship so that he could leave the island, and the next morning he found a ship.
The first man decided to leave alone. As the ship was about to leave, the first man heard a voice, “Why are you leaving your friend on island?”
“My blessings are mine alone, since I was the one that prayed for them,” the first man answered. “His prayers were all unanswered.”
“You are wrong!” the voice said. “He had only one prayer, which I answered. If not for that, you would not have received any of our blessings.”
“Tell me”, the first man asked, “what he prayed for?”
“He prayed that all your prayers would be answered.”
For all we know, our blessings are not the fruits of our prayers alone, but those of others’ prayers for us The first man decided to leave alone because he thought ________.
