Think about the different ways that people use 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 (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏僻的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. 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 high costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

While Jennifer was at home taking an online exam for her business law class, a monitor(监控器)a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven’t just searched the Internet to get the right answers.
Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone number they once used.
Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.
【小题1】Why was Jennifer watched in an online exam?
A.To correct her typing mistakes. |
B.To find her secrets in the room. |
C.To prevent her from slowing down. |
D.To keep her from dishonest behaviors. |
A.advanced technique | B.sharpening tool |
C.effective rule | D.dividing line |
A.they can attract potential students |
B.they can defeat academic cheating |

Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.
【小题1】What is the text mainly about?
A.The terrible conditions in the Antarctic. |

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
【小题1】Why do people kill animals?
A.They kill animals for something they need. |
B.They kill animals to raise some money. |
C.Animals destroy their natural resources. |
D.Animals create many problems. |
A.they give us a source of food |
B.they are beautiful and lovely |
C.they keep the balance of nature |
D.they give us a lot of pleasure |
A.People care much about animals because they need them. |
B.Once a certain kind of animal is gone forever, there will never be any more. |
C.Killing all rats and mice may cause some new problems. |
D.People must not kill any animal or plant. |

Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our Study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don’t see一and guide whether we see fear.”
To further understand this relationship, the scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person’s feeling of fear.
“We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear,” Dr Garfinkel said.
“We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder.”
【小题1】What is the finding of the study?
A.One’s heart affects how he feels fear. |
B.Fear is a result of one’s relaxed heartbeat. |
C.Fear has something to do with one’s health. |
D.One’s fast heartbeats are likely to cause fear. |
A.volunteers’ heartbeats when they saw terrible pictures |
B.the time volunteers saw fearful pictures and their health conditions |
C.volunteers’ reactions to horrible pictures and data from their brain scans |
D.different pictures shown to volunteers and their heart—brain communication |
A.Order. | B.System. |
C.Machine. | D.Treatment. |
A.treating anxiety and stress better. |
B.explaining the cycle of fear and anxiety |
C.finding the key to the heart-brain communication |
D.understanding different fears in our hearts and heads |

High-tech machines have made life easier for millions around the world.However, some people still prefer low-tech ways of doing things.Here’s an example of why this is happening.You can microwave a frozen hamburger in 60 seconds.However, it won’t taste as good as one you cook on the stove.And if you’re in that much of a hurry, you probably won’t take time to toast the bun.High-tech cooking saves time, but it doesn’t make for better-tasting meals.
Most people get their news from high-tech sources like television or the Internet.This has many advantages.For example, electronic news is more up to date than newspapers or magazines.It’s also more exciting to see live and videotaped news events than photographs.However, newspapers and magazines have some important advantages.They give more background and details.They also let you read the parts that are important to you and skip the rest.
Other high-tech timesavers have similar disadvantages.For example, most people use the phone or e-mail to stay in touch with friends and family members who live in other places.But when you use the Internet or the phone, you won’t always think carefully about what you are saying, and sometimes you forget the important things you want to communicate.Similarly, when you word-process a homework assignment instead of handwriting it, you can check your spelling electronically and put in fancy headings.However, some students are so busy with the computer that they don’t pay enough attention to the actual words they are writing.
【小题1】Which of the following statements is TRUE according to the passage ?

February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.
On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest in the third century Rome.

(London)If it really is what's on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn't surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body's communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.
【小题1】What is this piece of news mainly about?
A.Thin people also have troubles. |
B.Internal fat is of no importance. |
C.Internal fat leads to many diseases. |
D.Thin people may be fat inside. |
A.being slim doesn't mean you are not fat inside |
B.internal fat is the cause of heart disease and diabetes |
C.being slim is not dangerous at all |
D.the exact dangers of internal fat |
A.People with heart disease all have internal fat. |
B.People can get rid of internal fat by improving diet. |
C.Men are more likely to have too much internal fat. |
D.Exercise can help to reduce the internal fat. |

It's common for parents to feel emotional when the moment comes for their child to leave home and go to university. Even parents who don't speak about the event are likely to feel a sense of sadness because it’s the end of an era where you and your family were at the centre of your child's world. As a parent you’ll probably continue to support your child in different ways, but the main job of raising your child is over. It's a huge change for everyone involved.
There are a few things that you can do to make the transition easier. Plan carefully for your child's departure and think about how you can help. Many parents take their child to university for the first time. If you decide to do that, be ready to feel a real wrench when the time comes to say goodbye. Your child will probably be as nervous as you are about the moment when you finally say goodbye – but that might not show!
Be positive and cheerful about the choice your child has made to continue studying, and plan to leave once you've unpacked the car and looked around your child's new living accommodations. If you can, save your tears for the car – you'll make things easier on your child and yourself.
The more you've invested in being a parent, the more you'll feel a sense of loss, so the sadness you feel now is a sign that you've been a good mom or dad. Remind yourself that parenting is all about raising an independent and confident child who functions well without you. If your child quickly settles and starts enjoying himself, you should congratulate yourself.
It's also only fair to allow yourself some time to grieve(悲痛). Don't expect to pick yourself up and move on straight away. But you may decide to find a hobby or sport to fill your extra time. Perhaps you've always wanted to learn a new language, go to yoga classes or take up swimming. You may decide to spend more time with family and close friends, who are likely to be feeling the absence of your child as well.
Agree on the best approach to staying in touch before your child leaves, and stick to your agreement. Try not to panic if your child doesn't respond immediately – remember, they're starting a new and busy life.
【小题1】Why do parents feel sad when their child leaves home for college?
A.Because the absence of their child makes them feel lonely. |
B.Because their children will start a new life in college. |
C.Because it means the end of love between parents and their child. |
D.Because they are no longer the main focus of their children’s life. |
A.sorrow | B.regret | C.anger | D.love |
A.Supporting your child in different ways all the time. |
B.Congratulating yourself when your child goes to college. |
C.Preparing your child to stand on their own feet in the future. |
D.Investing as much as possible in the growth of your child. |
A.Developing a new hobby or sport |
B.Learning a new language. |
C.Spending more time with close friends |
D.Staying in touch with your child. |
