We’ve used the wind as an energy source for a long time.
The Babylonians and Chinese were using wind power to
pump water for irrigating crops 4,000 years ago, and sailing
boats were around long before that.Wind power was used in the
Middle Ages, in Europe, to grind(磨碎) corn, which is where
the term “windmill” comes from.
We can use the energy in the wind by building a tall tower, with a large propellor(螺旋桨) on the top.The wind blows the propellor round, which turns a generator to produce electricity.We tend to build many of these towers together, to make a “wind farm” and produce more electricity.The more towers, the more wind, and the larger the propellors, the more electricity we can make.It"s only worth building wind farms in places that have strong, steady winds, although boats and caravans(大篷车)increasingly have small wind generators to help keep their batteries charged.
The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains — places where the wind is strong and reliable.Some are offshore.To be worthwhile, you need an average wind speed of around 25 km/h.Most wind farms in the UK are in Cornwall or Wales.Isolated places such as farms may have their own wind generators.In California, several “wind farms” supply electricity to homes around Los Angeles.
The propellors are large, to obtain energy from the largest possible volume of air.The blades can be angled to cope with varying wind speeds.Some designs use vertical turbines (垂直涡轮机), which don’t need to be turned to face the wind.The towers are tall, to get the propellors as high as possible, up to where the wind is stronger.This means that the land beneath can still be used for farming.
1.The first paragraph aims to introduce to us _______.
A.the function of wind power B.the source of wind power
C.the nations using wind power D.the history of using wind power
2.The best places for building the wind farm are places where _______.
A.boats and caravans can often be seen B.isolated farms don’t have enough electricity
C.there are less human activities D.the wind is strong and reliable
3.We can infer from the passage that _______.
A.wind farms will not take up too much farming land
B.wind farms need no fuel because wind is free
C.the blades can be angled to turn to face the wind wherever it comes from
D.the higher and larger the towers are, the stronger the wind is
4.What can be a suitable title for the passage?
A.Where to build a wind farm. B.ABC of the using of wind energy.
C.How to make best use of wind. D.Wind energy is the best energy.

Increasing affluence(富裕)and currency appreciation are behind the spike in Chinese students traveling abroad for their undergraduate studies, industry insiders said.
The Ministry of Education last month reported that a record 840,000 high school graduates did not register for the gaokao (university entrance exam) this year. Those numbers are fueling speculation that this was due to the increasing number of Chinese students wanting to study abroad.
The total number of students traveling abroad to study increased from 144,000 in 2007 to 170,000 last year. This figure will probably top 200,000 this year, said Feng Jishang, marketing manager of Wiseway, a consulting firm that advises students and their parents about overseas schools.
Years ago, most Chinese students who went abroad would first complete their undergraduate studies in China before applying to an overseas graduate school. But this traned is changing. According to industry estimates, the proportion of students seeking their first degree abroad has risen to 30 to 50 percent of all overseas-bound students. That means there could be as many as 60,000 to 100,000 such students this year—— triple the number in 2003.
Foreign college campuses are beginning to notice the trend. A source tat the University of San Francisco told China Business Weekly that the campus used to accept three or four Chinese undergraduate students every year. Today, the number has hit 80, the university source said.
Rapid economic growth, coupled with a currency that has risen by more than 20 percent against the US dollar over the last four years, is making an overseas education more affordable for Chinese students. That’s making US campuses such as the University of San Francisco, or USF, more of a bargain. “ Students used to tell me that they did not have the money to go to USF, and they needed full scholarships. That is not the case now,” said Stanley Nel, vice-president of international relations at the San Francisco campus.
Another reason is that there simply aren’t enough places in Chinese colleges, especially the higher-rated ones, to satisfy the demand for a university education. “ Four in ten students taking the gaokao won’t get university places. Furthermore, of those that do many don’t get into the schools of their choice. That is why more are going abroad,” Feng of Wiseway said.
A widespread perception among students is that going overseas for college improves their career prospects, sources said. “ For Chinese students, capability is not a problem, but they need work experience and communication skills,” said Alan McNeilly, assistant dean at Teeside University in the United Kingdom. “ If they get a degree overseas, they can expect higher salaries and better positions when they return,” McNeilly said. His university will set up an office in China next month to attract more students, Mc Neilly added.
1.More and more Chinese students have recently traveled abroad for studines because______.
A.they don’t want to take part in the gaokao
B.most Chinese students want to study abroad
C.many Chinese people become richer and US dollar has been devalued
D.it is easy to complete their undergraduate studies
2.Which of the following statistics-related statements is NOT true?
A.The number of students seeking their first degree abroad is around 20,000 to 33,000 in 2003.
B.The increment of the total number of students traveling abroad to study is probably bigger from 2008 to 2009 than that from 2007to 2008.
C.The number of Chinese undergraduate students accepted at USF is about 20 to 26 times of that in the past.
D.200,000 out of the 840,000 high school graduates who did not take the gaokao this year started their undergraduate study abroad.
3.Students interested in studying abroad take the following factors into account EXCEPT_____.
A.financial affordability
B.work opportunities after graduation
C.accommodation standard
D.the chance of getting into a more desirable university
4.What can be inferred from this passage?
A.If the Chinese RMB decreases 20 percent against the US dollar, the number of Chinese students traveling abroad to study will decrease 20 percent.
B.If more universities are established in China, fewer students will choose to study abroad.
C.Teeside University will set up an office in China to attract those students who have been admitted to USF but have not been offered full scholarships.
D.Without a degree overseas higher salaries and better positions are not impossible if you are experienced and have outstanding communication skills.
During the school year many parents take on the role of driver as they drive their children from one lesson to another. Many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we can overdo it, leaving our children feeling a little burnt out, and according to parent educator Diane Loisie, it"s their school work that suffers the most. "After school, if they"re busy in a number of sporting events, besides they need to do their homework, then the time they"ll feel sleepy is in the classroom. Your child needs free time. So if you"re filling up that after school time, then it"s during the day that they"re going to be taking a break. "
Professor Claire McDermott agrees that there"s a lot to be gained from sometimes putting those scheduled lessons and activities away. "Relaxing time is important for children. It"s time just to do the things they want to do. A child can go up to their room, or they can play around. It doesn"t look like productive time; parents certainly wouldn"t be saying ‘Wow, are they ever learning things now?’ But this relaxing time gives both the body and the brain just a wonderful chance to relax after a day. It helps a child prepare for sleep, and it also helps to understand the learning that"s gone on that day. "
It"s hard to prevent signing our kids up for some activities and lessons. After all, many of us want our children to have a head start in life and the chance to join in great activities in the arts or sports is a part of that. However, Loisie feels that in the long run most children feel better with just a few key activities because it gives them an opportunity to master them. "When we get our children in too many activities because we want our children to experience everything, then what we"re doing is setting them up not to be good at one thing or gaining a skill." So choose your children"s activities wisely. It may be one of the best things you"ve ever done for your kids.
1. What is the biggest disadvantage for children to attend too many lessons after school?
A. They can get bored easily about everything.
B. They might have no time to do the homework.
C. They might not pay much attention to learning.
D. They can not easily focus on learning during the day.
2. What should we think of children"s playing around aimlessly?
A. It is productive.
B. It is helpful.
C. It is a bad habit.
D. It is a waste of time.
3. Why should parents limit the activities our children attend?
A. Because children have no time.
B. Because children cannot learn many things.
C. Because children do not have enough sleep.
D. Because children cannot focus on too many activities.
4. What is the main idea of this passage?
A. Don"t be children"s drivers after school.
B. Choose activities for your children wisely.
C. Make your children learn as much as possible.
D. Let children learn something from various subjects.
31st October —— A team of British explorers has announced they are going to the North Pole to measure the ice cap’s thickness. The exploration will take ground-based readings (仪表的读数) of an ice formation which most scientists agree is shrinking at an alarming rate.
Explorer Pen Hadow’s three-member team will pull a sled-fixed radar device, which measures ice density every eight centimeters, 2,000 kilometers across the Arctic and will produce millions of readings.
They will leave in February, 2008 and will face temperatures of -50℃ on a journey that will take up to 120 days. They have been testing their equipment in Britain and Canada.
Hadow is excited about the prospects (前景), “For the first time we will be able to transmit video images — webcam film of the expedition — as it unfolds so people can track us, and the whole idea is to engage as many people as we can in what we’re doing.”
New fallen snow on top of the ice makes ground-based measurements more accurate than satellite data.
“It has been in the planning stage for a while,” said Hadow. “We spent the last two years developing impulse radar (冲击雷达), which normally is about 100 kilograms and hangs under an aircraft and so on. We’ve managed to get it down to about 4 kilograms. It’s the size of a briefcase and we are dragging it behind the sled as we go.”
The ice cap shrank enough in 2007 so that a pathway through the cap known as the Northwest Passage opened up during the melting of the Arctic summer.
Cambridge University’s Joao Rodrigues explains, “Thickness of the ice cap will determine how much solar radiation will be reflected and the heat exchange between the ocean and the atmosphere and it is thus a vital component (成分) of climate models.”
If warming trends continue, some experts predict that the Arctic Ocean could be ice-free during the summer within a few decades.
1 What would be the best title for the text?
A. Exploration to the North Pole.
B. Arctic ice cap shrinking.
C. Arctic ice survey announced.
D. Ground-based measurements of ice.
2. What is special about the exploration?
A. It will be broadcast live on the Internet.
B. Explorers will use a sled-fixed radar device.
C. Explorers will travel in extremely cold conditions.
D. Ground-based measurements are more accurate.
3. What is the purpose of the exploration?
A. To measure the ice cap’s thickness.
B. To study whether ice will disappear in the Arctic.
C. To make a film about the Arctic exploration.
D. To make people interested in what they are doing.
4. It can be inferred from the passage that ________.
A. ice in the Arctic will disappear in ten years
B. the exploration will last for half a year
C. Hadow spent two years developing a kind of radar, which is about 100 kilograms
D. if there is snow on ice, satellites can’t measure the ice thickness accurately enough
5. From the passage, we learn that ________.
A. the explorers will measure ice density every other centimeter
B. people will be able to follow the explorers and see what they are doing
C. people could go through the Northwest Passage in the 2007 Arctic summer
D. the equipment that Hadow’s team use will be tested in the United States
第三部分: 阅读理解 (共15小题;每小题2分,满分30分)
阅读下列短文,从每题所给的四个选项A、B、C和D中,选出最佳选项,并在答题卡上将该项涂黑。
When I stepped out the plane from Miami into Charlotte, North Carolina, airport for a connecting flight home, I immediately knew something was wrong. Lots of desperate people crowded the terminal. I quickly learned that flights headed to the Northeast were called off because of a storm. The earliest they could get us out of Charlotte was Tuesday. It was Friday. A gate agent stood on the counter and shouted, “Don’t ask us for help! We cannot help you!”
I joined a crowd that ran from terminal to terminal in search of a flight out. Eventually, I found six strangers willing to rent a van with me. We drove through the night to Washington, where I took a train the rest of the way to Providence.
The real problem, of course, is that incidents like this happen every day, to everyone who flies, more and more often. It really gets to me, though, because for eight years I was on the other side, as a flight attendant for Trans-World Airlines (TWA).
I know the days are gone when attendants could be written up if we did not put the lines napkins with the TWA logo in the lower right-hand corner of the first-class diners’ trays. As are the days when there were three dinner options on flights from Boston to Los Angeles in economy class. When, once, stuck on a tarmac(机场停机坪)in Newark for four hours, a planeload of passengers got McDonald’s hamburgers and fries by thoughtfulness of the airline.
I have experienced the decline of service along with the rest of the flying public. But I believe everything will change little by little, because I remember the days when to fly was to soar (翱翔). The airlines, and their employees, took pride in how their passengers were treated. And I think the days are sure to come back one day in the near future.
1..Many people crowded the terminal because ________.
A. they were ready to board on the planes
B. something was wrong with the terminal
C. the flights to the Northeast were canceled
D. the gate agent wouldn’t help the passengers
2. How did the writer get to Providence at last?
A. by air B. by van
C. by train D. by underground
3. Which of the following is NOT true according to the passage?
A. Incidents happened to those who fly quite often.
B. The writer used to be a flight attendant for Trans-World Airlines.
C. Even a small mistake might cause complaints from passengers in the past.
D. McDonald’s hamburgers and fries were among regular dinner options.
4. What can be implied from the passage?
A. The writer lived in Charlotte, North Carolina.
B. The writer thought the service was not as good as it used to be.
C. The writer with other passengers waited to be picked up patiently.
D. Passengers would feel proud of how they were treated on the plane.

In the United States more than 80 colleges now accept just only women. Most of them were founded in the 19th century. They were set up to 21 women the education they could not get anywhere else. At that time 22 of the universities and colleges 23 only men. In the past 20 years many young women have 24 to study at colleges that accept both men and women. As a 25 , some women’s colleges decided to accept men students, too. Others still refused to change. Now the women’s colleges are 26 again.
The president of Trinity College in Washington D. C said by the end of the 1980s women had come to 27 that studying at the same colleges with men and women did not mean 28 had the same chance to 29 . The president of Smith College in Massachusetts said “A women’s college 30 women to choose classes and activities 31 . For example, if a woman student wants to learn math, she will be given the chance. So the percentage of students who like to study math in a women’s college is 32 than that in a college with men and women.”
Experts say men students in the United States 33 have enough courage to speak in class. 34 , women students can’t. In a women’s college, women feel free to say 35 they want to. According to a report, women colleges also 36 leadership ability in many fields. At a women’s college, every 37 office is held by women. Recent studies 38 that this leadership continues after 39 . The studies also prove that it is easier for the American women who went to women’s college to 40 successful jobs later in life. Maybe that is why this kind of college is liked by people now.
