"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said.

Scientists are working to use that energy to make electricity.  Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. "Waves are one of nature's ways of picking up energy and then sending it off on a journey."

When waves come toward the shore, people can set up darns to block the water and send it through a large wheel called a turbine (涡轮机). The turbine can then power an electrical generator to produce electricity.

"The resource is huge," said Janet Swain of the World-watch Institute. "We will never run out of wave power." Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth's surface - that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.

Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic.

Traditional sources of energy like oil and gas may someday run out. "Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!

1. The writer uses the two questions at the beginning of the passage to ______.

A. test the readers' knowledge about waves     B. draw the readers' attention to the topic

C. show Jamie Taylor's importance           D. invite the readers to answer them

2. The underlined phrase "picking up" (Paragraph 2) is closest in meaning to ______.

A. starting again    B. speeding up          C. gathering        D. improving

3. We can make better use of wave energy if we ______.

A. shorten its journey to thousands of homes

B. build more small power stations on the oceans

C. reduce the cost of turning it into electric power

D. quicken the steps of producing electricity

4. It can be inferred（推论） that some day we might not worry about ______.

A. air pollution     B. our boat traffic    C. our power supply   D. our supply of sea fish

Earth's next superpower

The following countries have been sitting on hidden talents. And now they're about to fly.

NIGERIA (尼日利亚)

Nigeria says it pumps out as much oil as the other two oil-producing countries,Kuwait and Iraq. All this oil is cycling cash into the Nigerian economy and creating extremely rich businessmen. Analysts say that if Nigeria can improve its schools and technology，it could balloon into the world's 13th largest economy by 2050，right between Turkey and Italy. If that reason is not enough for optimism，Nigeria's president also has the sunniest name of any world leader: Goodluck Jonathan.

VIETNAM

As agriculture has given way to industry，unemployment in Vietnam has dropped. What's Vietnam's trick? It's ready to work. Other countries' laborers aren't as cheap as they used to be，which makes Vietnam a relative bargain for companies that need new factories abroad. However，the country has almost no railroads，its highways are in poor condition，and its largest city has just one airport，which was built before the Vietnam War. So what's the use of producing export-ready goods if there's no convenient way to ship them? The good thing is that，however，officials are widening highways，building a new airport and so on.

CHILE (智利)

Pipes，computers，motors，and your microwave all have one thing in common: They're made with copper (铜). Copper makes the world go round. And luckily for Chile， it's got about a third of the planet's copper supply. It just needs a way to dig it up and the government is pouring money into the country's mines.

1.Which country will Nigeria be expected to follow in respect of economy by 2050?

A.Kuwait. B.Iraq.

C.Turkey. D.Italy.

2.What's the problem Vietnam is facing?

A.It doesn't have money to build new factories.

B.Its people don't have enough food to eat.

C.It is suffering from the Vietnam War.

D.Its transport system is very poor.

3.What will Chile depend on to get developed?

A.High tech.

B.Natural resources.

C.Investments from other countries.

D.The government's good administration.

4.Which of the following is the best title of the text?

A.Countries with a lot of money B.Developed countries

C.Countries in great need of money D.Countries about to take off

My house is made out of wood, glass and stone. It is also made out of software.

If you come to visit, you'll probably be surprised when you come in. Someone will give you an electronic PIN (个人身份号码) to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights nearest to you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.

Of course, you are also able to tell the house if you want something. There is a home control console(控制台), a small machine that turns things on and off around you.

The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.

I believe that ten years from now, most new homes will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've put in today.

I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, "How will I live without them?"

1. What does the passage mainly discuss?

A. How to develop a new system.

B. The function of the PIN.

C. A home for the future.

D. Easy life in the future.

2.What can’t be done in the writer’s new house according to the passage?

A. Turning on the lights.　　　　　　　　 B. Going swimming.

C. Getting a telephone call.　　　　　 D. Playing music.

3. The writer's new house is different from ordinary ones mainly because _______.

A. it has your favorite music following you

B. you can make a telephone call anywhere

C. the writer is able to change his new idea into practice

D. it has been controlled by computers

4.What is the writer most likely to be according to the passage?

A. An IT expert　　 B. A famous doctor

C. An idealist　　 D. An experienced teacher

高二英语阅读理解中等难度题查看答案及解析

It is 7 am and the alarm is going off. You know you have to be out of bed to catch the bus. But the urge to bury yourself in the bed is ever so strong. Sounds familiar? Why is it that teens find it difficult to get themselves out of bed in time every morning or stay sharp and focused during the first couple of hours of school?

During adolescence, the body goes through many changes and these include a shift in sleep patterns. Researchers from MIT have been tracking the body’s need for sleep in teenagers. They found that though adolescents need as much as 9.5 hours of sleep a day, they get to bed later and later with each passing year. In fact, the sleep cycle shifts later by as much as 12 to 18 minutes each year between the ages of 10 and 20! So by the time a 10­year­old who sleeps at 8 pm grows to be 17 or 18, his body naturally wants to stay up till 10：30 pm or 11 pm.

According to researchers, this is because of a hormone called melatonin (褪黑激素) that is secreted (分泌) by the pineal gland — a tiny structure deep inside the brain. Melatonin regulates the body’s natural day­night rhythms. It causes a person to become sleepy by lowering his body’s core temperature. In teens, melatonin is secreted much later in the evening and continues to increase throughout the night. This makes it difficult for teens to fall asleep earlier as they did in their younger years. Likewise, the effect of melatonin continues until much later in the morning, making it hard for them to wake up early.

A study found that at least one in four teens is tired and falls asleep in school at least once a week. During sleep, important body functions and brain activities happen. So how can teenagers get their sleep enough? The American Academy of Pediatrics (AAP) recommends that middle and high schools should start later — not before 8：30 am. This should give teens some more time to sleep at night.

1.From Paragraph 2, we can learn that if you sleep late, the next day you should ________.

A. stay sharp　　 B. skip breakfast

C. get up late　　 D. stay up late

2.What does the underlined word “this” in Paragraph 3 refer to?

A. The students want to stay up.

B. The shifts of the sleep cycle.

C. The pineal gland secretes melatonin.

D. The adolescents sleep late.

3.The teens go to sleep later than before because ________.

A. melatonin is secreted much later

B. melatonin regulates the sleep time

C. they sleep a lot in the daytime

D. they need to finish their homework

4.According to AAP’s recommendation, middle and high schools should ________.

A. let teens sleep in the day　　 B. let the students be active

C. delay the start time　　 D. start later at 8 am

Right now in China, talks on the street have been about the strange weather and it's raising a lot of concerns. A heavy haze(雾霾) has blanketed many cities in the northern and southern parts of the country in part of an unusual weather system that’s descended on the nation.

The haze stretches over a vast area, from Hebei and Shan-dong Provinces in the north all the way to Zhejiang, Anhui, Jiangsu, Hunan and Fujian provinces in the south. At its worst, the smog is reducing visibility to less than 200 meters and disrupting traffic, both on the ground and in the air. The weather front has also led many to worry about the possible health impacts.

Many cities are waking up to another day covered by a dense haze. In Beijing, drivers have to keep their lights on even though it’s already past eight o’clock in the morning. Even driving at very slow speeds, the roads can still be very dangerous. In some of the worst hit areas, drivers can’t even tell the colors of traffic signals. Authorities have stepped in to close off many highways across the troubled region. In Shandong Province, the highways that are open are backed up for miles. And traffic police have stepped up their patrols.

In the region’s airports, flights information boards have gone red. A huge number of flights have been delayed or cancelled, nearly three hundred in Beijing alone, leaving thousands of passengers stranded. Some are more frustrated than impatient. Passenger from Jinan airport, Shangdong province, said: “I’ve been waiting for more than five hours. It’s Mother Nature, so there’s really nothing we can do.” The airport is urging passengers to confirm with their carrier whether their flight will still take off as scheduled.

Back on the city streets, people are wearing breathing masks to get free from any ill effects. Fog has cleared a little in Shanghai. But damage has already been done. Shanghai resident said: “I’ve been wearing the mask, but still, my throat feels sour and itchy. I think it’s because of the weather.”

The weather forecast predicts a cold front is about to sweep across central and eastern China tomorrow. Many are hoping that this will clear away the depressive haze as well as the harm it brings.

1.The harm the smog caused didn’t include　　　　 .

A. reducing visibility to less than 200 meters
