In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about a half a dozen generate (引起,导致) the strong, circling winds of 75 miles per hour or more that give them hurricane status, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people.
The great storms that hit the coast start as innocent circling disturbances hundreds--- even thousands--- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the trade winds. When conditions are just right, warm, moist air flows in at the bottom of such a disturbance, moves upward through it and comes out at the top. In the process, the moisture in this warm air produces rain, and with it the heat that is converted to energy in the form of strong winds. As the heat increases, the young hurricane begins to swirl in a counter-clockwise (逆时针方向) motion.
The average life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane’s rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months.
Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours resulting in sudden floods. Worst of all is the powerful movement of the sea, the mountains of water moving toward the low-pressure hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore.
When is an ordinary tropical storm called a hurricane?

A.When it begins in the Atlantic and Caribbean seas.
B.When it hits he coastline.
C.When it is more than 75 mils wide.
D.When its winds reach 75 miles per hour.

What is the worst thing about hurricane?

A.The destructive effects of water.
B.The heat they release.
C.That they last about nine days on the average.
D.Their strong winds.

The counter-clockwise swirling of the hurricane is brought about by           .

A.the low-pressure area in the center of the storm
B.the force of waves of water.
C.the trade winds
D.the increasing heat

Apparently the word “downpour” in the fourth paragraph means           .

A.heavy rainfall
B.dangerous waves
C.the progress of water to the hurricane center
D.the increasing heat

In the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.
My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.
Then I got married with another dream: building my family with a combination of adopt and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic---and very emotional. A year later came our second adopted boy. Then followed son No. 3. In 2003, I gave birth to another boy.
You can imagine how fully occupied I became, raising four boys under the age of 18. Our home was a complete zoo---a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up the dream either. I had only one choice: to find a way. That meant taking as few as one class each semester.
The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, But I knew I should set an example for them to follow through the rest of their lives.
In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree!
I am not special, just single-minded. It always struck me that when you’re looking at a big challenge from the outside it looks huge, but when you’re in the midst of it, it just seems normal. Everything you want won’t arrive in your life on one day.
It’s a process. Remember: Little steps add up to big dreams..

Passage 1
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.

Getting rid of dirt, in the opinion of most people, is a good thing. However, the attitudes to dirt are always changing.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, and washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief above was longlived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ.Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many firsttime parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary,Mary Ruebush,an American immunologist(免疫学家),encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
The kings of France and England in the 16th century closed bath houses because ________.

A.they believed disease could be spread in public baths
B.they thought bath houses were too dirty to stay in
C.they lived healthily in a dirty environment
D.they considered bathing as the cause of skin disease

B.By making comparisons.
C.By following the order of importance.
D.By following the order of time.

What is the author's purpose in writing the passage?

A.To stress the role of dirt.
B.To introduce the history of dirt.
C.To present the change of views on dirt.
D.To call attention to the danger of dirt.

For centuries, the body's blood has been linked closely with the emotions. People who show no human emotions or feelings, are said to be cold-blooded. For example, the police are searching for a cold-blooded killer. He seems to kill for no reason, and no emotion, as if taking someone's life as nothing.
Cold can affect other parts of the body. The expression “get cold feet” has nothing to do with cold or your feet.The expression means being afraid to do something you have decided to do.For example, you agree to be president of an organization.But then you learn that all the other officers have resigned(辞职), and all the work of the organization will be your responsibility. You are likely to get cold feet about being president when you understand the situation.
The expression “give someone the cold shoulder” probably comes from the physical act of turning your back toward someone, instead of speaking to him face to face. You may give a cold shoulder to a friend who has not kept a promise he made to you. Or, to someone who has lied about you to others.
A cold fish is not a fish.It is a person.But it is a person who is unfriendly, and shows no love or warmth. A cold fish does not offer much of himself to anyone. Someone who is a cold fish could be cold-hearted. Now a cold-hearted person is someone who has no sympathy. Several popular songs in recent years were about cold-hearted men or cold-hearted women who, without feelings, broke the hearts of their lovers.
“Out in the cold” means not getting something that everybody else got. A person might say that everybody but him got a pay raise. He was left out in the cold. And it is not a pleasant place to be.
When you refuse to speak to a man and treat him in a distant way, you may express by “_____”.

A.I give him the cold shoulder
B.I think he is a cold-blooded man
C.I think he is a cold fish
D.I'm likely to get cold feet

Children today are crazy about roller skating(溜冰), for it's easy and fun. After supper on week days, anytime on weekends and especially any day in school holidays, so many roller skaters flow into streets, squares, parks and playgrounds. What a beautiful sight!
But a long time ago, roller skating was a different story. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin,whose work was making musical instruments. In his spare time he liked playing the violin. Merlin was a man of ideas and dreams. People called him a dreamer.

He tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Very proud of his invention, he couldn't wait for the special day to come, when he would arrive at the party on wheels while playing the violin.
On the night of the party Merlin did as he had planned, rolling into the room playing his violin. Quite astonished,all present cast their eyes over him. Then, unexpectedly, came one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin's grand entrance for a long time!
