ClozeThis summer, heavy rains have caused huge floods which have killed more than 1,000 people and (1) more than 1 million homeless in China and Eastern Europe. Scientists at the Earth Summit said (2) these natural disasters were a wake-up call for human beings to (3) more quickly to stop the planet from becoming too hot.The United Nations has made the environment one of the (4) areas for discussion at the summit in Johannesburg, South Africa. About 65,000 people from 185 countries are attending the meeting, which is being held from August 26 (5) September 4.Scientists say that many things that humans have been doing over the past 100 years, (6) deforestation (采伐森林) and sending greenhouse gases into the atmosphere, have changed the (7) of the earth.Robert Watson, the UN's (8) scientist, believes the earth's temperature could (9) by up to 5.8 degrees centigrade over the (10) century."This change will (11) more extreme weather patterns, such as floods and droughts," he said at the summit.This summer the central and southern China have faced floods (12) deforestation and soil erosion (水土流失).

The region (15) just half its normal yearly rainfall from June 1 to August 29. Farmers have had to buy water from other places.The Chinese officials at the Earth Summit say greenhouse gases are one of the country's biggest (16) problems. This is because these gases are one of the biggest reasons why there has been such a great change in the earth's climate.As more people use more cars, more gases will be sent into the air, which will cause the earth to get warmer."The situation will become worse (17) China doesn't choose the right means of transport," said Liao Xiaoyi, president of the non-governmental group Global Village.

More language inputAt the end of the 20th century, the world is changing in important ways. Until recently, nations acted independently. Each country did its business and tried to solve its problems alone. But now, the economy is worldwide and communications technologies have connected people all over the globe. Many problems are global, too, and can no longer be solved by individual nations.Environmental destruction is one of these problems. As the world's population has grown and technology has developed, the environment has suffered. Some nations have begun to try to stop the pollution and the environmental destruction. But the environment is global---the atmosphere, the oceans, and many forms of life are all connected. Thus, the solution requires global thinking. The problem of ocean pollution is a good example. All the oceans of the world are connected. Pollution doesn't stay where it begins. It spreads out from every river and every harbor and affects bodies of water everywhere.For centuries, people have used the oceans as dumping place. Many cities take tons of garbage out to sea and dump it there. The quantity of garbage that ends up in the water is incredible. Five million plastic containers are thrown into the world's ocean. These include human waste and chemicals used in agriculture. And every year, oil tankers accidentally spill millions of gallons of oil into the sea.Some people believe that the oceans are so large that chemicals and waste will disappear. However, many things, such as chemicals and plastics, stay in the water and create problems. They eventually float to shore and are eaten by tiny sea creatures. Then the larger animals that eat the tiny creatures are poisoned and die. Harbors and coasts around the world have become unsafe for humans or animals. The world's fish populations are rapidly shrinking. Another global pollution, problem concerns the atmosphere. Until recently, chlorofluorocarbons (CFCs) were used around the world in manufacturing refrigerators. Scientists discovered that these CFCs were destroying the ozone layer in the atmosphere. The ozone layer helps protect the earth from the sun's rays. without this layer, most forms of life on earth----including humans----probably would not be able to live.CFCs will soon be completely banned in the United States and in most developed countries are some of the most populous on earth, such as India and China. These countries need to change their refrigerator factories to non-CFC processes. But they may not be able to make this change alone. They will need help from the industrialized countries. This is what global thinking means----working together for solutions.1.This passage is about ___________.A.are pollutionB.old ways of thinking第5页共11页C.global thinkingD.refrigerator factories in China2. Until now, most nations thought that ____________.A.all countries should share their problems.B.all nations were enemies.C.Each nation should take care of its own problems.D.What happens in China affects everyone.3.The solution to ocean pollution requires global thinking because____________.A.no one cares about the oceanB.the oceans are so large.C.more oil is needed in the developing countries.D.all the world's oceans are connected.4.Nations must learn to think globally because_______.munication technologies will solve our problemsrge businesses will spread around the worldC.changes in the world require stronger nationsD.that is the only way to solve global problems5.You may infer from this passage that in the past____.A.problems were more localB.nations were more interested in the environmentC.the economy was more globalD.individual nations did not have as many problems.Unit 10 Frightening natureI. SpeakingTask 1 The Day After TomorrowDirections: Have a look at the introduction to the movie “The Day After Tomorrow”, and try to answer the following questions:⑴Have you seen the movie?⑵If so, how do you like it?⑶What would the world look like if it lost its battle against the greenhouse effect and global warming?"The Day After Tomorrow (后天)" shows a global disaster and destruction thanks to the weather.In the movie, Jack Hall, a weather scientist, is the first man to realize that a new ice age is coming. In one of several natural disasters, his sonSam becomes trapped in New York's Public Library when a tidal wavestrikes the city. He is forced to fight rapidly dropping temperatures and apack of hungry wolves escaped from the zoo. Meanwhile, Jack must thinkof ways to save his son, himself and the whole world. He must follow ahard path north, as everyone else races south to live in warmer climes.This film also brings a direct attack on the refusal of the US governmentto reduce greenhouse gas emissions (排放). It is hoped that "The DayAfter Tomorrow" may encourage a change in the government's attitudetowards environmental protection.II. Understanding the text1.

Government meteorologists(气象学者) said that unexpected monsoonal winds blew directly across the country from the Southern Hemisphere at about 100km/h, producing several rounds of stormy weather. Nearly 250 houses in the capital Colombo were damaged.Mt Etna EruptsSicily’s Mount Etna volcano(火山) erupted shortly after midnight on July 1, shooting “bombs” of lava(熔岩) nearly 1.5 meters in diameter on the eastern side of the mountain. The 30-minute eruption could be seen for several miles, but did not threaten any nearby villages.HurricaneHurricane Blas lost strength as it moved over cooler waters in the Pacific Ocean to the west of Mexico.

They see the sights that Pompeii is famous for ---- its stadium and theatres, its shops and restaurants. The tourists do not, however, see Pompeii's people. They don't see them because Pompeii has no people. No one has lived in Pompeii for almost years.Once, Pompeii was a busy city of 22,000 people. It lay at the foot of Mount Vesuvius, a grass-covered volcano. Mount Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not.In August of Ad 79, Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.For centuries, Pompeii lay buried under stone and ash. Then, in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in Ad 79. There were streets and fountains, houses and shops. There was a stadium with 20.000 seats. Perhaps the most important of all, there were everyday object, which tell us a great deal bout the people who lived in Pompeii. Many glasses and jars had some dark blue color in the bottom, so we know that the people of Pompeii like wine. They like bread too, metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread - a type of bread that is still sold in Italy today. Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye-makeup.Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.4. Why do large numbers of people come to Pompeii each year?A.To visit the volcano.B.To shop and eat there.C.To watch sports and plays.D.To see how Pompeiians lived.5. Why had so many Pompeiians remained by volcanic Mount Vesuvius?A.The city nearby offered all kinds of fun..B.The area produced the finest wine in Italy.C.Few people expected the volcano to erupt again.D.The mountain was beautiful and covered with grass.6. Why did the city uncovered look almost the same as it had looked in AD 79? Because ___________.A.Ginseppe and his men dug it slowly and carefullyB.the city was buried alive and remained untouchedC.scientists successfully rebuilt the city width everyday objectsD.nobody had lived in the city ever since the volcano erupted7. What do we know about the Pompeiians who lived years ago? They ____________.A.lived more or less the same as Italians now doB.liked women wearing all kinds of makeupC.enjoyed a lazy life with drinking and eatingD.went back to Pompeii after the eruption in AD 79.Key:Unit 9I.⑴waiting for; ⑵live away from; ⑶live through; ⑷are forced to;⑸on average II. 1-5 DDABC 6-7 BBIII. ⑴conference ⑵issues ⑶poverty ⑷heads⑸sustainable development ⑹growth ⑺population⑻natural resources ⑼developing countries ⑽differencesIV. 1.
