People used to think that wetlands were wasted land. Developers would drain them with ditches(水沟),fill them in with tons of soil,and build houses,schools,and parking areas on them.Then scientists began to realize the important role wetlands played in the environment.
Wetlands act like giant sponges(海绵) during storms.They soak up extra storm water and afterward release it slowly back into the water cycle.This helps prevent flooding. Towns where people have drained wetlands have found that in a big storm,their streets and homes are often flooded because there are no wetlands to soak up the excess water.
Wetlands also act as giant filters where pollutants are absorbed and dissolved over time.Though wetlands can become polluted from dumping,wastewater,and fertilizer runoff from farm fields,they are able to process some pollutants over time because of all the microorganisms and plants living there.
Wetlands are especially important for providing homes and breeding grounds to millions of birds,fish,and amphibians worldwide. Many wetlands have become national wildlife refuges(避难所),where you can go to take pictures and look at birds and animals.
The Everglades are a huge wetland that once covered more than four million acres of southern Florida. Sometimes called the “river of grass”,the Everglades are a shallow sheet of water that slowly flowed across a grassy plain. In the late 1800s people began draining parts of the Everglades for development. Roads were built and towns sprang up.The Everglades shrank to half its original size. Cities like Miami grew up where once there was a thriving wetland. Sewage and waste from the cities were pumped into the remaining wetlands. Over time scientists began to see the importance of the Everglades. Even with its smaller size,the Everglades filtered the pollutants coming from the cities,absorbing the worst of it like a sewage treatment plant. During storms the Everglades protected the cities from storm surge flooding. They also are just a great place to visit and see wildlife.
1.The first paragraph is intended to tell us________.
A.wasted land used to be wetlands

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, as well as one of the oldest. Evidence shows that windmills began to be used in the 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 radios. 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 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.
1.From the text we know that windmills _______.
A. were invented by European armies
B. have a history of more than 2,800 years
C. have rarely been used since electricity was discovered
D. used to supply power to radio in remote area
2.The underlined word in Paragraph 2 probably means________.
A. making something cleaner
B. making something flow freely
C. making something flow in a particular direction
D. making something into small parts
3.One of the reasons wind was discovered in the 1970s is that_______.
A. it is one of the oldest power sources
B. wind power is cleaner
C. it was cheaper to create energy from wind
D. coal and gas failed to meet the needs
4.What would the author probably discuss in the paragraph that follows?
A. The global trend towards producing power from wind.
B. The design of wind power plants.
C. The worldwide movement to save energy.
D. The advantages of wind power.

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, as well as one of the oldest. Something 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 get water from deep underground. When electricity was discovered in the late 1800s, people living in faraway 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 hardly used.
During the 1970s, people started becoming more cared 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 run out one day. 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.
1.What was a new use for wind power in the late 19th century?
A. Sailing a boat.
B. Producing electricity.
