Nuclear power's(核能的) danger to health, safety, and even life itself can be described in one word; radiation(辐射). Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being completely by killing masses of cells (细胞) in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed completely. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth.

Lisa Pina never thought she would need the fire safety training she received during her apprenticeship (学徒期) as a union painter and dry waller. On Friday morning，she was thanking God she had it.
On Thursday night，while Pina was babysitting her granddaughter，nephew and two nieces in her sister’s apartment，she smelled smoke and realized the apartment building was on fire. When her 4yearold granddaughter Ilean Garcia began saying，“We’re going to die，”she knew she had to act.Pina,39，first sealed the door，and then told all four children to get on the floor. After calling 911，she told the children to start singing and promised them all treats as soon as they reached safety. “I said，‘OK，we’re going to lie down and we’re all going to play a game，’” Pina said. “We all started singing our ABCs and 123s.I was just trying to make it fun.” Pina patiently waited，and a few minutes later，Riverside County sheriff’s deputies (治安官的助手) arrived. Pina，Ilean,8yearold Gabriel Parga,5yearold Aubreyana Parga and 4yearold Meriyah Parga were all trapped on the second floor as flames filled the first story. Pina did the only thing she could. She opened the window and dropped the children，onebyone，into the arms of the sheriff’s deputies about 15 to 20 feet below. “I just needed to keep the kids calm so they wouldn’t be afraid，”Pina said.“I was deathly afraid inside，but I couldn’t let them know that.”[Not long after dropping the children out of the window，firefighters arrived with a ladder and rescued her. Ten people were treated at the scene for suffering smoke，but nobody was seriously injured.

When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said “the phone”. Personally, I could do without the phone entirely, which makes me unusual. Because the telephone is changing our lives more than any other piece of technology.
Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day. If the phone did not exist, would she have anything to talk about?
Point 2 The mobile phone means that we are never alone. “The mobile saved my life,”says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance(救护车) to her rescue.
Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at any time of day to ask where they are , where they are going, and how their last meeting went.
Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”
Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously ( 同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access(存取) the Internet, the biggest library on Earth.
1.How do you understand‘Point 1 —The telephone creates the need to communicate, …’？
A. People don’t communicate without telephone.
B. People communicate because of the creating of the telephone.
C. People communicate more since telephone has been created.
D. People communicate more because of more traffic.
2.Which of the following best shows people’s attitude towards mobile phones?
A. Mobile phones help people deal with the emergency.
B. Mobile phones bring convenience as well as little secret to people.
C. Mobile phones are so important and should be encouraged.
D. Mobile phones are part of people’s life.
3.It is possible to talk to several complete strangers simultaneously through _______.
A. the TV screen
B. a fax machine
C. the phone line hooked up to the computer
D. a microphone
4.The best heading for the passage is _________.
A. Phone Power B. Kinds of Phone
C. How to Use Phones D. Advantage of Phones
