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

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.

There are about 80,000,000 mines* under the ground in more . than 60 countries. It is difficult and dangerous to clear these rnines, About 50 people including many children were’ killed ‘or htirt each iay. In 2003, APOPO, a Dutch research com pan y that uains the an imals, came up with the-idea of s\ng rats to search for the mines.
The animal trainers ‘found that a kind of rats from Africa were clever and had.a sharp* sense of smell. The rats were about 75 cm long and.weighed about l.35 kg, light enough to run across a minefield without setting off the mines.
In January 2004, the APOPO started this project. First, the trainers let the 4-week-old baby rats get familiar with humans. A few weeks later, the rats were no Ionger afraid of people and ‘the things around them. Then they were trained to connect a click* sound with food. After the rats had leamed that, the trainers then taught them to tell the difference between the smell of mines and other smells. When the rats could do it, the click was sounded and they were given a bit of banana. The method was called clicker training. “The training isn’t easy, said trainer Abdullah Mchomvu. “You have to be patient. Sometimes I get angry, but then again, I tell myself these are animals.”
After nine months’ training, the rats were taken to a minefiel山 They’ran across the minefield, stopped, sat and scratched the ground to tell the deminers* that they smelt out’a mine. Then the mine was cleared. It had taken two ‘deminers a day to clear a 200㎡ . minefield, but with the help of two rats ‘they could finish it in two hours.
The rats and ~he deminers saved thousands of lives, “The rats did this job much better than we expected. So far they have helped to make almost 2,000,000㎡ of land safe. They are heroes,” said Bart Weeqens, the head of the APOPO.
