America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.
Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.
Another difficult point for us Chinese to understand Americans is that although they include us warmly in their 
personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice（惯例） in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not m
anage the time to do a great deal with a visitor outside their daily routine（常规）. They will probably expect us to get ourselves from the airport to our own hot
el by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.
For the Americans, it is often considered more friendly to invite 
a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

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.

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 |

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?
| A．The Carnival of Brazil is often held after Easter. |

| C．The Carnival of Brazil is a festival to regret and begin a new life. |
