C

Indian scientists have designed a new device* that they hope will solve one of the biggest problems with the use of solar energy. They call the device a solar tree. Solar trees have metal “branches*” which are just from a tall pole at different levels. Each branch holds a solar panel*. These panels have large metal boards that collect energy from the sun and turn it into electricity.

Daljit Singh Bedi is the main scientist at the Council of Scientific and Industrial Research in India. Bedi says the shape of the solar trees makes it possible to fit more solar panels in a space than traditional systems do. This means less land would be needed to produce solar energy. “It takes about four square meters of space to produce energy which may need 400 square meters of space,” he says.

Scientists believe the energy a solar tree collects will be enough to power five homes. The solar tree will make it easier to provide solar energy for homes in cities. The trees will also take less space from farmers in rural areas. Bedi says solar trees will collect more energy than normal solar panels on the tops of buildings. “This design makes the solar panels exposed* more towards the sun,” he says. “And that way people are able to use 10 to 15 percent more energy.”

India has promised to reduce its greenhouse gas production. The country’s promise depends heavily on increasing solar energy. The cost of solar panels has gone down in recent years. This has increased the possibility of applying*solar trees in India.

Amit Kumar is the senior director of the Energy and Resources Institute in New Delhi. He says gaining access* to land takes time and increases costs. He adds that it is still not clear how useful these new developments in solar power technology are. “Only when we put those trees on a large scale* will we be able to get that answer,” he says.

1.We may probably read this passage in ___________.

A. Culture Views　　 B. Nature and Science

C. Story Books　　 D. Travelling Guide Book

2.Compared the traditional system, the main advantages of the solar tree is _____________.

A. we can see many “branches” in new solar tree

B. it surely produces more energy than traditional system

C. it’s reducing India’s more greenhouse gas production now

D. fewer and fewer people will use it than traditional ones

3.What does the underlined word "this" in the fourth paragraph refer to (指代)？

A. greenhouse gas production　　 B. the solar panels

C. the new solar tree　　 D. country’s promise

4.In the last paragraph, what do you think of what Amit Kumar said?

Dolphins are our friends. They can use tools to solve problems although they don’t have hands. For example, scientists have ever found that a dolphin can make a shy eel (鳗鱼)　 come out of the hole with a dead fish.

Dolphins use different sounds to get or give information. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of some words, but also understand the importance of word order in a sentence.

Most animals enjoy playing, but dolphins seem to like making their games as exciting as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the “game” and continued playing with the dolphins for more than an hour.

Dolphins live in a very different world from ours, but they are very good at our “IQ tests”. For example, they will jump out of the water when they hear a whistle from the keeper. They do this because they will get a fish as a prize.　

There is still much to learn about these cute problem-solvers, but it is sure that watching a dolphin show is fun.

1.What can a dolphin use to make an eel come out of the hole?

A.A small mouse. B.A dead cat. C.A dead fish. D.A little dog.

2.How do dolphins get and give information?

A.By using tails. B.By using tools. C.By using words. D.By using sounds.

3.Where did the dolphins throw the dog when playing?

A.Onto its back. B.Into the air. C.Onto the beach. D.Into the water.

4.What does the underlined word “whistle” mean in Chinese?

A.音量 B.音速 C.口哨 D.音标

5.Which is the main idea according to the passage?

A.Dolphins can understand many languages. B.Dolphins are a kind of clever animals.

C.Scientists have known dolphins well enough. D.Dolphins can make their games relaxing.
