Most scientists are now certain that global warming is taking place. Gases such as carbon dioxide are creating a warm blanket around the earth. This blanket is trapping heat in the atmosphere, and so raising the temperature of the earth.
In Europe, eight of the last ten years have seen record high temperatures. On the other hand, the countries around the Mediterranean Sea are receiving even less rain than before. In Sub- Saharan Africa the crops are drying out in the fields and people are dying of starvation. In 1999, the southern United States was struck by a serious of destructive(毁灭性的) hurricanes. Scientists expect such trends to continue, and to worsen, if global warming cannot be stopped.
In addition to worrying about rising global temperatures and extreme weather conditions, scientists are closely monitoring sea levels around the world. They are slowly rising, as the northern and southern polar ice caps start to melt. This will have serious consequences for low-lying countries near the sea. Already parts of these places are disappearing under the rising sea water.
According to a new research, one contradictory feature(特征) of global warming is that it will probably lead to a period of much colder weather. Scientists base their theory on what happened the last time the world warmed up, 8,300 years ago. They have discovered that when the ice melted from the northern polar ice cap it became trapped in a lake in northern Canada. As more ice melted, this lake suddenly burst open, pouring millions of tons of freezing fresh water into the North Atlantic. This flood of water prevented the normal flow of water in the Atlantic, which takes warm water from the tropics(热带地区) north to Europe. When this flow of warm water was cut off, temperatures in Europe dropped by between three and eight degrees over the next 200 years. ''That's the concern here,'' says Richard Alley, an American climate expert. ''The climate hasn't varied much in 8, 000 years. But big changes could come back!''

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbacks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全书), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
1.It can be inferred from the passage that ________.
A.TV programs are a chief provider of knowledge
B.cinemas are the best choice in getting information

2.What does the sentences “Television has not killed reading, however ” underlined in the second paragraph suggest?

3.What can we learn from the passage?
A.Fewer and fewer people will buy books.
B.A good dictionary should be kept in every home.
C.Books with hard covers sell better than paperbooks.
D.More people like TV programs about famous men.
When traveling abroad, it is wise to carry your money in traveler's checks because checks are protected against loss or theft. If your checks are lost or stolen, the issuing authority will refund(赔偿) your money.
Not only are they safe, they are also convenient. They are available in different currencies and they can be cashed at most banks throughout the world. Most shops, hotels and restaurants also accept them.

Hannah McKeand was born in Bristol in 1973. She got a degree in Classics at Lampeter University. After working as a marketing manager, she decided at the age of 31 to devote herself entirely to her primary passions (热情), exploring, adventure and the outdoors. She would take part in various expeditions (探险), in the Egyptian desert first, then in the remote valleys of northeast of Afghanistan, and then in Antarctica.
In 2001 her urge to explore began to develop with a trip to the Western Desert on the borders of Egypt, Libya and Sudan in search of prehistoric rock art. This trip took Hannah to the center of the second biggest wilderness on the planet, an uninhabited (无人居住的) area the size of India.
In 2004 Hannah joined a British expedition to explore the Wakhan Corridor in the northeast of Afghanistan in search of the source of the River Oxus. The upper (上部的) areas of this mountain valley had rarely been visited by Westerners.
Later that year Hannah turned to a cold desert in a 56-day expedition from the coast of Antarctica to the South Pole. Crossing one of the harshest (最严酷的) environments in the world, the team of five battled with physical and mental exhaustion, injury, hunger and some of the lowest temperatures on earth.
In 2006 Hannah returned to Antarctica and once again skied from Hercules Inlet to the South Pole, but this time alone and unsupported. She set a new world record for the journey of 39 days 9 hours and 33 minutes.
In October 2007 Hannah began her first full adventure season traveling from Australia across to Chile and from there around Cape Horn and down to Antarctica.
Hannah hopes that by writing and speaking about her experiences in the world and sharing them with those who care to read or listen, she will inspire people to go after their own dreams and achieve their own goals.

Li Daiyu and her cousin Liu Qian were on a trip to Canada to visit their cousins on the Atlantic coast. Rather than to take the airplane all the way, they could fly to Vancouver and then take the train from west to east across Canada. The thought which they could cross the whole continent was exciting. Canada is the second large country in the world. One of the most popular cities is Vancouver on which many people live. The coast north of Vancouver has some of the oldest and most beautiful forest in the world. It is so wet there that the trees are extreme tall. Looked out of the train window, they saw mountain goats, which were being protected, and even a grizzly bear and an eagle. They learned that most Canadians lived within a few hundred kilometers of the USA border, and the population is only slightly over 30 million.
