Starting a new school term is always exciting. It is a chance to see all of your friends again. But most exciting of all, the new term is an opportunity to take up new hobbies. As you know, it is common in Britain for students to take up new hobbies after the Christmas holidays. Promising to begin something new is a common New Year resolution for many school teenagers.

Most schools offer different kinds of hobby classes. Students take them in their free periods or after school. Some classes you have to pay for and others are free of charge. For example, I once took a free Wednesday evening gymnastics class that my school offered. But when I learnt how to play the drum my parents had to pay for the lesson, and they did so, like most parents, without any complaint.

The most popular extra classes at my school were piano lessons and drama club:　 Both classes offered exams students could take. Because the extra classes may take up much time of the students, students with many hobbies sometimes felt more stressed than those without any. But they could enjoy their life better than those who didn't foster (培养) any hobbies at school. For example, they could build up good friendship with the persons who shared the common interest with them. Most important of all, the students with hobbies left school with many extra skills.

Frankly speaking, I haven't continued any of the hobbies I began at school. But I have never regretted taking them. After all, my best friend today is someone whom I met in my gymnastics class. The reason why we are still keeping in close touch with each other is that we have much in common.

A new device (设备) called Orion is helping those who are blind to see. It does this in a new way by helping them experience the world around them.

Jason Esterhuizen lost his eyesight after a car accident. He never thought he would be able to see light or movement again. But now with the movement of a switch (开关), his world suddenly grew brighter.

He says, “I still can’t put it into words. I mean from being able to see absolutely nothing, it’s completely black, to all of a sudden seeing little flickers (闪烁) of light move around.” It is not full or normal sight, but Esterhuizen can move about in the world around him.

The new technology uses several parts. One is a small device placed in the brain. The other parts are a video camera on sunglasses and a processing device that can be carried in a person’s clothes. When the user points the camera, a signal goes to the processor (处理器) and then back to the glasses. The glasses then are in wireless communication with the device in the brain. The information causes a pattern to develop in the part of the brain. The pattern helps users sense or see movement and shapes of light. And it all happens in seconds.

Esterhuizen is one of just two people in the U.S. testing this technology. He says that “I can tell someone moving across the room, walking past me or walking away from me, or it’s a light against the wall. It is just amazing to have some form of functional vision again.” He adds that now he can do everyday activities around his home that he once could not. It is easier to walk outside.

The researchers believe that one day this technology could help people who have lost their vision because of illnesses like diabetes. It may also help those with poor vision or who were born blind.

1.Which of the following caused Esterhuizen to go blind ?

A.An illness. B.A car accident.

C.A brain damage. D.A genetic problem.

2.What can we know about sunglasses of the new technology?

A.They are put in the brain.

B.They are carried in the user’s clothes.

C.They are mainly used to protect a person’s eyes.

D.They communicate wirelessly with a small device.

3.What can we infer about Esterhuizen in paragraph 5?

A.He fully regains his sight.

B.He always do daily activities freely.

C.He feels delighted to see the world again.

D.He is the only one to test this technology.

4.What is the main idea of the text?

A.Orion makes homes brighter.

B.Orion functions as normal eyes.

C.A new equipment helps the blind see.

D.A new technology happens in seconds.

Seth DeBolt is a plant scientist at the University of Kentucky US. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity.

The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply.

Professor DeBolt went on a study trip to rural Indonesia. He saw that there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens.

Little waste meant there was little that could be used for fuel. Growing a separate fuel crop would take land away from food crops. That was something Professor DeBolt did not want to do.

DeBOLT said, "The people at most risk with respect to energy poverty, typically they're the same people who have food insecurity issues as it is. And then any change in availability would be most damaging to that group of people."

But he found one item that was in plentiful supply and would not create competition between food and fuel. Coconut shells are generally thrown out. Yet Professor DeBolt says it has an "excellent" heating value. All someone needs is a way to release that energy.

DeBolt says he and his team see possibilities for coconut power. "Coconuts are growing here and these are the areas where there is possibility for energy poverty to be eased at least in part by these small-scale production systems."

The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia. Other tropical countries with large crops of coconuts and similar fruit could benefit, as well.

But DeBolt says this is not a perfect solution. There are technical questions, like how to safely deal with the dangerous waste produced in the process. And there needs to be money to get these projects started.

1.Professor DeBolt went on a study trip to rural areas of developing countries to________.

A. help farmers make full use of waste

B. seek certain materials to make electricity

C. persuade farmers to grow more coconuts

D. find a suitable place to carry out the experiment

2.DeBolt thought it was not a good idea to grow fuel crops because________.

A. there are plenty of coconuts

B. local farmers have no interest in it

C. it would make food problems worse

D. fuel crop has little use for local farmers

3.The last two paragraphs mainly tell us that coconut power________.

A. needs further experiments and efforts

B. can help solve energy problem perfectly

C. will cause technique and money problems

D. has drawn Indonesia's government attention

4.What might be the best title for the passage?

A. Make Full Use Of Coconuts            B. Make Power From Coconuts

C. A Perfect Solution                            D. Food And Energy Problems

All scientists subscribe to the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. Some byproducts of this process1. (call) “greenhouse” gases, and the most important one of2.is carbon dioxide. Dr. Janice Foster explained “There is a natural phenomenon3.is called the greenhouse effect. This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour trap heat from the sun and therefore warm the earth. 4.for the greenhouse effect, the earth would be about 33 degrees Celsius cooler　 than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends to be trapped in the atmosphere 5. (cause) the global temperature to go up.
