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, 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 levels 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 grandparents.
Radiation can hurt us. We must know the truth.
Which of the following statements is true?

A．Nuclear radiation is just like common radio waves.

B．Nuclear radiation can cause cancer to human beings.

C．Nuclear radiation can be detected by human senses.

D．Nuclear radiation can be safe to human beings if its level is low.

How can nuclear radiation kill an animal?

A．By damaging its heart.	B．By killing a few cells.
C．By hitting any place in its body.	D．By killing many cells in important organs.

If a human being is hit by nuclear radiation, he may _______.

A．die of cancer after many years	B．die immediately
C．have a child who may be born weak	D．all of the above

You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough.
After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month?
The photograph of me taken the day I started this trial demonstrates(展示）perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster（光泽）. It looks dead. Even my lips look shriveled（枯萎的）. This is all classic evidence of poor hydration, apparently.
Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste.
Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing.
Which statement is Not True according to Paragraph 1?

A．The author drinks about a liter of liquid every day.

B．The author has something in common with a camel.

C．The author thinks she drinks enough water every day.

D．The author actually has plenty of water in her daily life.

A．Because she was very fond of doing experiments.

B．Because she was informed of the importance of drinking enough water.

C．Because her doctors forced her to do it.

D．Because she wanted to be cured of her stomachache.

The author’s lack of hydration caused the following physical responses Except_______.

A．shriveled lips

B．enough luster of her skin

C．dark shadows around her eyes

D．wrinkles and blotches on her face

A．the more water one drinks, the healthier he is

B．drinking water makes ladies look younger

C．drinking enough water is key to one’s health

D．it’s necessary to follow specialists instructions

What will be probably written in the next paragraph?

Among various programs, TV talk shows have covered every inch of space on daytime television. But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and Oprah Winfrey shows.
Jerry Springer could easily be considered the king of "rubbish talk". The show takes the ever-common talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people's lives.
Like Jerry Springer, Oprah Winfrey takes the TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a "final word". He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The show's main audience are middle-class Americans. Most of the people have the time, money and ability to deal with life's tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society.
Compared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey shows are _______.

A．more interesting.	B．unusually popular.
C．more detailed.	D．more formal.

Though the social problems Jerry Springer talks about appear unpleasant, people who watch the shows ________.

A．show disbelief in them.	B．are ready to face up to them.
C．remain cold to them.	D．are willing to get away from them.

Which of the following is likely to be a topic of the Oprah Winfrey show?

A．A new type of robot.	B．National hatred (憎恨).
C．Family income planning.	D．Street accident.

What is the advantage of the Jerry Springer show?

A．The show exposes the dark sides of society.

B．The show pours poisonous waste into society.

C．Jerry sums up (总结) the whole idea of the show.

D．Jerry talks about the improvement of society.

She is a cute, quiet girl. As a daughter, she has no secrets from her mother, who is very pleased with her. But recently she has become somewhat mysterious, not so open as before: what if she falls in love, which is too early for a girl of her age. After all, she is reaching the “dangerous stage”. These thoughts have caused trouble in the mother’s mind.
One weekend the girl came to tell her mother that she was going to the cinema with her schoolmates and would return late. This was the first time her mother had agreed, and she couldn’t help worrying because her daughter had never been away at night before. The mother waited till nine and her uneasiness(不安) got the upper hand over her. She decided to go out to meet her daughter. Just at that moment the noise of a car pulling up drew her to the window and ---there was her daughter, waving goodbye to a boy. Her heart missed a beat. When the girl came in, the mother was watching TV, pretending nothing had happened. “Mum, I’m back.” “Yeah.” “Sorry to be late. Still sitting up?” “Yes, Oh, that… Who’s that boy?” The daughter was stunned (发愣) for a moment. “Ah. It’s my monitor. He gave me a lift on his way home. Mum, I’m going to bed” “All right. Go to sleep early.”
Next morning, when the mother went to the daughter’s room to do some tidying, she found her diary left at her pillow. After a few minutes’ hesitation she finally opened it to the entry of the night before. It read: Mum, it was love that made you ask, but it would show your understanding of me if you hadn’t. Holding the diary, the mother fell in thought.
