九年级英语单项填空中等难度题查看答案及解析
Today there are more fires than in the past . Over 100,000 wildfires burn each year in America . Russia has 20,000 to 35,000 wildfires and Australia has about 60,000 each year. These fires destroy（损害）huge areas of forests and burn hundreds of homes .
Many experts believe there are several reasons for this sudden increase in fires. The first reason is climate（气候）change . In 2010, Russia had the hottest and driest summer with strong winds in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives .
Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire as quickly as they could. They didn’t allow the grass and trees to burn. As a result , today many forests have thicker vegetation（植被）which provides more fuel（燃料）for fires . So surprisingly, America has many more fires today partly because of its past fire-fighting practices.
Scientists now understand that a fire can be a natural part of a healthy forest. As a result, countries like Australia allow some fires to burn naturally. The fire makes old trees thinner. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore , if a fire is not a serious threat（威胁）to people , firefighters may let it burn naturally .
1.Russia had so many fires in one month in 2010 because __________ .
A. lightening spread the fire
B. there was much fuel for fires
C. there were not enough firefighters
D. it was very hot , dry and windy
2.__________ because of the traditional fire-fighting practices in the USA .
A. There are fewer wildfires
B. There are more fires today
C. The weather becomes warmer and drier
D. Trees and grass become thinner
3. The main idea of Paragraph 4 is that __________ .
A. fires are serious threats to human beings
B. Australian firefighters don’t put out fires
C. fires can play an important role in forests
D. it’s difficult for firefighters to control the fires
4. Which of the following is TRUE according to the passage ?
A. Two reasons for the increase in fires are mentioned.
B. Russia has the hottest and driest forest.
C. Australia allows all the fires to burn naturally.
D. There are more fires in Russia than in the USA.

Today there are more fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy huge areas of forests and burn hundreds of homes.
Many experts believe _______. The first is climate change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes, dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.
Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn't allow the grass and trees to burn. As a result, today many forests have thicker vegetation(植被). Thicker vegetation means more fuel for fires. also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.
Scientists now understand that a fire can be a natural part of healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat to people, firefighters may let it burn naturally.

A.there are several reasons for this sudden increase in fires

Our factories and homes burn coal and oil. Every year we have forest fires somewhere. Many scientists believe that the weather is changing.
The earth will perhaps be warmed by about 7℃ at the South Pole(极) and the North Pole. The ice will be melt(融化). The sea level(平面) will rise by about 7 meters. As a result, water will cover cities like London, Tokyo and New York. Some ports(港口) and towns along the coasts will disappear under water.
Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out(封闭) the ultraviolet rays(紫外线). Then the earth will become colder and great sheets of ice will cover Europe and North America.
When chemicals in the air mix with rain, we have acid(酸) rain. Acid rain can bring us great harm. It destroys(破坏) forests and kills life in lakes and rivers.
People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves.
