Since 2010, about 6.4 million acres have been burned on average per year. Recent studies have stated that global warming is the cause of these wildfires and higher temperatures, and that the incidence of these natural disasters is likely to increase.‎ ‎ As temperatures increase, wildfires become more common. As this cycle progresses, climate change and wildfires both increase frequently and seriously. Forest fires are also developing at higher frequencies as a result of global warming. Firefighters use techniques like back-burning to help prevent further spread of these fires, but these measures are not always effective.‎ ‎ Some factors that promote wildfires, such as drought and insect outbreaks, have been linked to global warming as well. Insects that kill trees and other plants make the remains more sensitive to fires, as the plant matter dries out and can more easily be burned. Higher temperatures that result from climate change cause more water to evaporate(蒸发)from reservoirs and lakes, which can lead to drought.‎ ‎ With global warming causing higher temperatures, the wildfire seasons of affected areas lengthen. This occurs because summer heat begins to build earlier in the year, and the cooling fall season is delayed. For forests in the southwest ‎ United States, the conclusion of snow’s melting indicates the time when fires are able to start. Climate change has caused the melting of snow to occur earlier than it did 50 years ago by about one to four weeks.‎ ‎ The global warming trend has hit Southern California extremely hard, and the months of January through April have been hotter this year than they have been for any others in recorded history. This has also caused a drought which has been severe or worse for the entire state. Last year, drought affected only 46 percent of California.‎ ‎ With the results from these recent studies, global warming has been linked to an environment that promotes wildfires, by creating higher temperatures and causing drought. California’s wildfire season is just starting, and the damages are likely to be worse as the season continues.‎ ‎1. What does the author intend to tell in the passage?‎ ‎ A. Global warming causes high temperatures and wildfires.‎ ‎ B. Forest fires have been bringing serious threat to the earth.‎ ‎ C. High temperatures make water disappear at a high speed.‎ ‎ D. California and Arizona are faced with the extreme weather.‎ ‎2. Why are insects connected with wildfire?‎ ‎ A. Because tons of insects exist in the forests.‎ ‎ B. Because drought drives insets into the forests.‎ ‎ C. Because insects leave the trees dead and dry.‎ ‎ D. Because the bodies of insects can burn easily.‎ ‎3. We can conclude from the passage that .‎ ‎ A. it is impossible to prevent wildfire from happening ‎ B. the southern states in the USA will see the longest summer ‎ C. it is necessary to raise awareness of fire prevention ‎ D. California has done nothing to fight wildfires ‎ 【语篇解读】全球变暖导致森林地带变得更干燥,而且干燥时间变长,增加森林大火的发生率,森林大火反过来使得地球气温上升,给生态环境带来伤害。‎ ‎1.
