Now satellites are 36 to forecast（预报）the weather. They are in space, and they can 37 any part of the world. The satellites take pictures of the atmosphere（大气），38 this is where the weather forms（形成）. They send these 39 to the weather stations. So meteorologists（气象学家）can see the weather of any part of the world. From the pictures, the scientists can often say 40 the weather will change.Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier 41 . Perhaps they may find that the clouds have changed during the last few hours. This may mean that the 42 on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.So the weather satellites are a great 43 to the meteorologists. 44 __satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for three or five days. Soon, perhaps, they may 45 forecast the weather for a week or more ahead（提前）.36.________________A. help B. to help C. helped D. helping

Air pollutionPeople and air pollution are often in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major kind of air pollution is the gas from cars. Statistics(统计资料) show that 93 percent of all auto trips are within cities.Another major kind of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the county.On the average, we throw away more rubbish than the year before. The burning of rubbish makes air pollution even worse. Many major industries are also responsible for the dirty air in the around cities. The fumes(烟)from iron, steel, chemical, and petrol production add particles(微粒)to the air.The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode(腐蚀). In some of the larger cities, these fumes endanger the lives of human beings by contributing to lung diseases and causing early death.26. The key point of the passage is that().A. the cause of air pollution is peopleB. the causes and the effects of air pollution are both found in citiesC. the effects of air pollution range from headaches to death27. What is the purpose of this passage?A. to persuade people to stop polluting the air().B. to tell the causes of air pollutionC. to tell why cities are bad places to live28. Why is air pollution more grave in the city than in the country?().A. Because there are larger populations in cities.B. Because the air in the city is dirty.C. Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country.29. The fumes from coal and oil may cause metal().A. to corrodeB. to twistC. to turn black30. In larger cities, the fumes from coal and oil may contribute to().A. heart diseaseB. loss of clear visionC. lung diseases

Motor vehicles powered by the internal combustion engines are responsible for over 80 percent of the deadly carbon monoxide as well as the cancer-causing substances in the air. Eighty-nine percent of the vehicles on the road in Massachusetts are privately owned and are often operated with only one person in the car. If people would use public transportation instead of their cars, air pollution levels could be significantly lowered. Thirty percent of the land in downtown Boston is devoted to cars. Where there are garages, there could be gardens. Where there are highways, there should be homes and places to work and play. Studies show that people today show a greater hearing loss with age than ever before. Much of this is due to car-horns, loud engines and general traffic noise.The cost of a personal car is high to the individual. The average person pays about $2,000 per car per year in gasoline, insurance, taxes, and maintenance. But for society as a whole, personal cars are a luxury we cannot afford. We pay in death from auto accidents, in poor health from air pollution, in loss of hearing from noise pollution, and in the destruction of our cities by the ever-increasing number of highways.1、It is ____ that are the main cause of the air pollution in Boston.A、vehicles in generalB、the public transportation systemsC、carbon monoxidesD、personal motor vehicles2、The writer’s purpose in writing this article is to _____.A、remind people of the danger of air pollutionB、warn people of the danger of accidentsC、urge people to use private cars as less as possibleD、ask the Boston government to build more homes and gardens3、According to the last paragraph, ______.A、the cost of personal cars is high to the individuals but not to the societyB、an average car costs about $2,000 inBostonC、personal cars are so expensive that most people cannot affordD、society as a whole suffers much from the ever-increasing number of cars4、It is implied but not stated that ______.A、garages, highways and parking areas occupy nearly one third of the total Boston downtown area.B、because of highways, people in Boston have no more homes and places to live, work and play.C、C garages have replaced most of the gardens in BostonD、Boston is the most seriously polluted city in the U.S.5、The best title for this passage is “ ______.”A、Air Pollution in BostonB、More Homes, More Plays for PeopleC、Cars Are Too ExpensiveD、Public Transportation, A Solution to Air Pollution

根据下面资料，回答
Germs are everywhere. You can′t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world′s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Your immune system (免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells (细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
What do antibodies do?

问答题The worst pollution threat is concentrated in and near large cities. There the people-made pollutants increasingly surpass the ability of air and water to dilute (冲淡；稀释) the contaminants (污染物) to safe levels. The natural ecological cycle depends on plants, which absorb some pollutants and release oxygen to the air. But near large cities, natural vegetation becomes scarce, and introduced trees, ornamental shrubs and gardens are far from adequate in absorbing motor vehicle and industrial air pollutants. Finally, some pollutants, most notably atomic waste, may continue to contaminate air, land, and water for thousands of years. Therefore, ecocrisis—ecocatastrophe or ecocide—has been for some time one of the major concerns of not only the ecoactivists and environmentalists, but of many scientists of other fields and the government authorities of many countries as well.
