Think about the different ways that people use the wind.You can use it to fly a kite or to sail a boat.Wind is one of our cleanest and richest power sources （来源），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 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 higher costs.Today,there is a global movement to supply more and more of our electricity through the use of wind.From the text we know that windmills .
| A．were invented by European armies |

| A．wind power is cleaner |
| B．it is one of the oldest power sources |
| C．it was cheaper to create energy from wind |
| D．the supply of coal and gas failed to meet needs |
What would the author probably discuss in the paragraph that follows?

On Nov.18th,1908,three men went up in a balloon(气球).They started early in London. The headman was Auguste Gaudron,and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way.
Soon they heard the sea. They were carrying the usual rope(绳子),and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to change its weight(重量).It was for use over the sea. They were also carrying some bags of sand.
After the sun rose, the balloon went higher. It went up to 3,000 metes, and the air was very cold. The water in the balloon became ice. Snow fell past the men's basket, and they could see more snow on the ground. The men tried to throw out some more sand; but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice.
At last they pulled the box into the basket. It was still snowing; so they climbed to get away from the snow. They rose to 5,100 meters! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely. They had traveled 1,797 kilometers from London!Three men flew in balloon ________.
| A．for nearly 1,800 kilometers | B．to another city |
| C．to visit Poland | D．more than a century ago |
The metal box was used for ________.

Edward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources(资源). How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性)of our earth.
Wilson begins with an open letter to the pioneer in environment (环境) protection, Henry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?
Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species(物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.
At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book. We learn form the text that Wilson cares most about ______
| A．the environment for plants | B．the biodiversity of our earth |
| C．the wastes of natural resources | D．the importance of human values |
How many species are most important to our present food supply?
| A．Twenty. | B．Eighty. | C．One hundred | D．Ten thousand. |
Wilson suggests that one way to keep biodiversity is to _______.
| A．learn how to farm scientifically |
| B．build homes for some dying species |
| C．make it clear what to eat |
| D．use more species for food |
We can infer that the text is _______
| A．a description of natural resources |
| B．a research report |
| C．a book review |
| D．an introduction to a scientist. |
Edward Wilson is _______
| A．a pioneer in environment protection |
| B．an American scientist in environment protection |
| C．a world-famous scientist in Asia |
| D．a well-known expert in nature in U.S.A |
“In my country, men usually go to restaurants on their own. They always take their shoes off before they go in. Then they usually sit on the floor around a small, low table. In the evening they often sing songs.”

The Carnival of Brazil is an annual festival held 46 days before Easter, especially famous for the Carnival in Rio de Janeiro. Carnival celebrations are believed to have roots in the festival of Saturnalia, which, adapted to Christianity, became a farewell to bad things in a season of religious discipline to regret and prepare for Christ’s death and coming back to life.
Modern Brazilian Carnival dates back to Rio de Janeiro in 1641. It originally copied the European form of the festival, later taking in elements of Native American and African cultures.
In the late 19th century, the strings (弦乐器) were introduced in Rio de Janeiro. These were pageant (游行) groups that paraded through city avenues performing on instruments and dancing. Today they are known as blocks, consisting of a group of people who dress in costumes or special T-shirts with themes or logos. Blocks are generally connected with particular neighborhoods; they include both a music group and a lot of revelers.
Block parades have become an expressive feature of Rio’s Carnival. Today, they number more than 100 and the groups increase each year. Blocks can be formed by small or large groups of revelers with a clear title. Before the show, they gather in a square, then parade in sections of the city, often near the beach.
Carnival time in Rio is very interesting, but is also the most expensive time to visit Rio. Hotel rooms and other lodgings (住宿) can be up to four times more expensive than the regular rates. There are big crowds at some locations and life is far from ordinary in many parts of town.What can we infer from the first paragraph?
