Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(风车) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(碾碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.
From the text we know that windmills________.

A.were invented by European armies
B.have a history of more than 2,800 years
C.used to supply power to radio in remote areas
D.have rarely been used since electricity was discovered

What was a new use for wind power in the late 19th century?

A.Sailing a boat. B.Producing electricity.
C.Grinding wheat into flour. D.Pumping water from underground.

One of the reasons wind was rediscovered in the 1970s is that_______.

A.wind power is cleaner
B.it is one of the oldest power sources.
C.it was cheaper to create energy from wind
D.the supply of coal and gas failed to meet needs

What would the author probably discuss in the paragraph that follows?

A.The advantages of wind power.
B.The design of wind power plants.
C.The worldwide movement to save energy.
D.The global trend towards producing power from wind.

Ever since Stephanie’s 13th birthday we have been receiving comments from other adults expressing their sympathies because our daughter is now a teenager.We’ve heard everything from,“Sure she’s a good kid,but just wait,now that she’s teenager…”to the ever inspiring,“Well,all kids are rotten when they are teenagers,just try to go through it the best way you can.”What’s more upsetting is that many of these insensitive adults feel the need to share their negative predictions well within the hearing of both our daughters.
I know that teenagers can be moody(闷闷不乐)and difficult at times,but I’m 38 and I can also be difficult and moody.We worry about the future and want today’s kids to know that we care
for them and that there are opportunities that wait for them.However, at the very point they set out on that journey toward adulthood we stand there watching them disapprovingly(不赞成),just waiting for them to make mistake.“just like we knew they would.”We tell them to respect themselves and to say no to drugs,yet we fail to set a positive example by treating them with kindness and consideration,demonstrating(示范)our respect for them.
I have,at times been guilty of this behavior but am now realizing that the more I see each person as a person,the more I am pleasantly surprised in some way or another. For example,a few weeks ago my husband and I were having dinner at our favorite restaurant and two teenage boys came in and sat down right beside US.I must admit that my first thought was,“perfect,there goes our quiet, peaceful dinner.”I was so wrong! These young men were well behaved.quiet and left a nice tip for the waitress.Once I looked beyond the jeans so loose they were practically falling off and the multi-colored hair, I saw what fine people these kids were.
Many of the people who,perhaps unknowingly, treat teens with disrespect are unhappy about the fact that pop singers and sports stars are our children’s heroes. I feel that unless We give them something better to go after, we really shouldn’t complain.
66.When their children reach their teens,parents usually expect_________.

68.When two teenagers came into the restaurant and sat beside the author, her first thought was that__________.
A.they were wrong to have chosen this restaurant for dinner
B.something interesting was going to happen over dinner
C.her quiet dinner with her husband would be ruined
D.she and her husband were going to have a pleasant surprise
69.What does the author think of the two teenage boys?
A.They may become nice people if they are willing to change their lifestyle.
B.They are typical of teenagers who wear ill-fitting clothes and dye their hair.
C.They’re fine young men despite their loose jeans and multi-colored hair.
D.They will respect you if you respect them.
70.What is the main idea of the last paragraph?
A.There is nothing wrong with teenagers admiring pop singers and sports starts.

C.Pop singers and sports stars should not be heroes of our children.
D.Parents should set a good example for their children to follow.


I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square. It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the Wasichus (Indian word for “white people”) have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve of thirteen years of age. But now it takes them very much longer to be bull grown.

Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water. But it also leads to a fossil fuel. Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years. Burning it releases fewer pollutants than oil or coal. The gas is mainly methane (甲烷). It produces half the carbon dioxide of other fossil fuels. So it may help cut the production of carbon gases linked to climate change.
Russia is first in what are called "proved reserves" of natural gas. The United States is sixth. Over the years, big oil and gas companies recovered much of the easily reached supplies of gas in America. They drilled straight down into formations where gas collects. As these supplies were used up, big drillers looked for similar formations in other countries.
But now the industry is taking a new look. Companies are developing gas supplies trapped in shale (页岩) rock two to three thousand meters underground. They drill down to the shale, then go sideways and inject high-pressure water, sand or other material into the rock. This causes the rock to fracture, releasing the gas. Huge fields of gas shale are believed to lie under the Appalachian Mountains, Michigan and the south-central states. Gas shale exploration is being done mainly by small to medium sized companies. Eric Potter, a program director, says more than half the gas in the United States is now coming from these new reserves.
But hydraulic (液压的) fracturing can also produce debate and anger over the risk of groundwater pollution. This method of drilling is not federally supervised under the Safe Drinking Water Act. Some in Congress want to end that exemption (豁免) from the law.
Natural gas provides Americans with about one fourth of their energy. And, unlike oil, most of it is produced in America. Gas producers invested heavily in reaching new supplies when prices were high. But prices are down sharply now because the depression cut demand for energy. So energy expert Eric Potter says it is too early to know how the changing market prices will affect the market for gas shale exploration.
68. We can learn from the first paragraph that ________.
A. natural gas releases methane and carbon dioxide
B. natural gas is considered as the cleanest energy
C. natural gas is more environmentally friendly than other fossil fuels
D. natural gas is a renewable source of energy
69. The word “fracture” in Paragraph 4 probably means _______.
A. create B. break C. change D. decrease
70. Gas shale exploration may cause disagreement because ______.
A. it may cause water pollution B. it brings too high profits
C. it breaks the law D. it is out of states’ control
71. According to Eric Potter, the new gas shale exploration ______.
A. will provide America with about one fourth of their energy
B. will increase demand for energy
C. will make gas producers invest a big sum of money
D. may be influenced by the changing market prices

He met her at a party. She was so outstanding, with many boys around her, while he was so normal, with nobody paying attention to him.
At the end of the party, he invited her to have coffee with him. She was surprised, but due to being polite, she agreed. They sat in a nice coffee shop. He was too nervous to say anything, and she felt uncomfortable, thinking, “Please let me go home.”
Suddenly he asked the waiter, “Would you please give me some salt? I’d like to put it in my coffee.”
Everybody stared at him—so strange!His face turned red, but, still, he put the salt in his coffee and drank it.
She asked him curiously, “Why do you have this hobby?”
He replied, “When I was a little boy, I was living near the sea. I liked playing in the sea, and I could feel the taste of the sea, just like the taste of the salty coffee. Now every time I have the salty coffee, I always think of my childhood. I miss my hometown so much. I miss my parents who are still living there.” While saying that tears filled his eyes. She was deeply touched. That’s his true feeling, from the bottom of his heart. A man who can tell out his homesickness, he must be a man who loves home, cares about home, and has responsibility of home. Then she also started to speak, about her faraway hometown, her childhood, her family. That was a really nice talk, also a beautiful beginning of their story.
They continued to date. She found that actually he was a man who meets all her demands; he was kind-hearted, warm and careful. He was such a good person but she almost missed him! Thanks to the salty coffee! Then the story was just like every beautiful love story, the princess married the prince, then they were living a happy life… And, every time she made coffee for him, she put some salt in the coffee.
After 40 years, he passed away, leaving her a letter which said, “My dearest, please forgive my whole life lie. This was the only lie I said to you—the salty coffee.”
“Remember the first time we dated? I was so nervous at that time. Actually I wanted some sugar, but I said salt. It was hard for me to change so I just went ahead.”
“I tried to tell you the truth many times in my life, but I was too afraid to do that, as I have promised not to lie to you for anything.”
“Now I’m dying, I’m afraid of nothing so I tell you the truth: I don’t like the salty coffee. What a strange bad taste! But I have had the salty coffee for my whole life!”
“Since I knew you, I never feel sorry for anything I do for you. Having you with me is my biggest happiness for my whole life. If I can live for a second time, I still want to know you and have you for my whole life, even though I have to drink the salty coffee again.”
Her tears made the letter totally wet.
Someday, someone asked her, “What’s the taste of salty coffee?”
“It’s sweet,” she replied.
