Nuclear power’s danger to health, safety...

Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.

Nuclear radiation has a certain mystery about it, partly because it cannot be detected 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 or 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 immediately by killing masses of cells in vital organs. 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 serious. This is the case when only a few cells are hit, and if they are killed immediately. 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 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 victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its parents.

Radiation can hurt us. We must know the truth.

Sheldon Cooper is a scientific genius on the popular American TV show---The Big Bang Theory. He finally met his match last year: Stephen Hawking.

This is not the first time that the scientist has appeared on TV. He has also been on Star Trek (in 1987) and The Simpsons (in 1989). Each time, he played himself.

Hawking, 71, is perhaps the world’s most famous scientist after Albert Einstein. He has spent his whole life studying the beginning and the end of the universe, including the Big Bang theory.

The Big Bang theory explains the early development of the universe. According to the theory, about 13.7 billion years ago everything was all squeezed together in a tiny, tight little ball, and then the ball exploded. The results of that explosion are what we call the universe.

Hawking has always tried to make science more popular with people. His book: A Brief History of Time was published in 1988. In the book he shares his understanding of the universe in simple language. The book tries to explain many subjects about the universe to common readers, including the Big Bang, black holes and light cones (光锥).

Hawking’s achievements are even greater if you think about his disability. When he was 21, Hawking caught a bad illness that slowly stopped him from moving or talking. Now he sits on a wheelchair with a computer by his side. To communicate, he moves two fingers to control the computer’s mouse. He chooses his words from the screen, which are then spoken by a voice synthesizer (合成器).

Hawking also believes that there might be aliens in space. However, he believes they are probably very dangerous, so we should not look for them. “I imagine they might exist in very big ships ... having used up all the resources from their home planet,” Hawking said in a British documentary named Into the Universe with Stephen Hawking.

1.What does the “two Bangs” in the title refer to?

A. The director of the TV show and the founder of it.

B. The director and the actor of “The Big Bang Theory”.

C. The scientific genius on the TV show and the one in real life.

D. The founder of the “Big Bang” theory and Sheldon.

2.The Big Bang theory mainly explains _____.

A. how the universe started

B. what the universe is like

C. how old the universe is

D. how the universe exploded

3.According to the passage, which of the following about Hawking is TRUE?

A. He was born with a disability.

B. He played an artist in Star Trek.

C. He uses a computer to communicate.

D. He believes aliens are our friends.

Dear Santa Claus,

My name is Amy. I am 17 years old. I have a problem at school. Can you help me, Santa? Kids laugh at me because of the way I walk and run and talk. I have cerebral palsy. I just want one day when no one laughs at me or makes fun of me.

Love, Amy

At radio station WJLT in Fort Wayne, Indiana, letters poured in for the Christmas Wish Content. When Amy’s letter arrived at the radio station, Manager Lee Tobin read it carefully. He thought it wound be good for the people in Fort Wayne to hear about this special girl and her unusual wish. Mr. Tobin called up the local newspaper.

The next day, a picture of Amy and her letter to Santa made the front page of the “News Sentinel”. The story spread quickly.

Suddenly the postman was a regular at the Hagadorn house. Envelopes of all sizes addressed to Amy arrived daily from children and adults all across the nation. They came filled with holiday greetings and words of encouragement. Some of the writers had disabilities; some had been teased as children. Each writer had a special message for Amy. Through the cards and letters from strangers, Amy saw a world full of people who truly cared about each other.

Many people thanked Amy for being brave enough to speak up. Others encouraged her to ignore teasing and to hold her head high.

Amy did get her wish of a special day without teasing at South Wayne High School. Teachers and students talked together about how bad teasing can make others feel.

That year, the Fort Wayne mayor officially declared December 21st as Amy Jo Hagadorn Day throughout the city. The mayor explained that by daring to make such a simple wish, Amy taught a universal lesson. “Everyone,” he said, “wants to and should be treated with respect, dignity and warmth.”

Homework will not be a concern for pupils attending a pioneering new secondary school in Norfolk. Instead, the 1,100 children will stay longer at school, doing extra study at school as part of the extended school day, which could last until about 5 pm.

Rather than setting homework that pupils could struggle with at home, where there may be limited access to computers, they will do that as independent study in the day. When they go home they should enjoy quality family time. That has been really well received by parents who respect the fact that family time will be family time. But the school would still expect youngsters to study at home ahead of important exams.

Independent learning at school would ensure equality because kids who get help with homework from parents might rely on others too much.

Peter Devonish , a teacher at the school, said, “Having the children at school a bit longer to strengthen their learning is a really good idea, because they can have their time with the family.” But he warned. “A disadvantage is that our school is in the countryside, which means it’s not so perfect to get children home at that time.”

Mr. Devonish said they also set pupils project-based homework, such as looking at an energy-efficient house, which allowed them to combine independent study with working with their parents.

Craig Morrison, another teacher, said, “A large problem with homework has been that not enough is done with it. With homework, a lot of effort can go into it, so it’s about celebrating what children do rather than processing it in terms of marking it and handing it back.”

1.How will students spend their longer days at school?

A. They will do homework on computers.

B. They will study all by themselves.

C. They will have fun with teachers.

D. They will prepare for exams.

2.Why is the new idea well accepted by some parents?

A. Because it helps kids with their homework.

B. Because kids will be educated well at school.

C. Because kids will enjoy quality family time.

D. Because parents can have more time to rest.

3.What is Mr. Devonish worried about?

A. The students may get home late.

B. No staff would like to stay till 5 pm.

C. More teachers will be needed.

D. The students may dislike the idea.

4.The passage is mainly about _______ .

A. teachers who are asked to stay at school longer

B. a school where children stay longer for homework

C. homework which students have to deal with

D. students who like spending time with teachers
