As climate change gets worse, global temperatures increase, and so does the risk of wildfires. A recent report from the United Nations shows that wildfires are becoming more common and severe. Wildfires have caused many problems across countries. These fires destroy (毁坏) homes and businesses, take lives and also damage the environment.

A wildfire in New Mexico, a state in the southwestern US, burned for nearly two months in 2022, damaging more than 1,275 km2 of land—an area about the size of the city of Los Angeles. Wildfires have created seasonal pollution in the northwestern US. Between 2002 and 2018, carbon monoxide (一氧化碳) levels increased every year for the month of August in the area.

In 2019 and 2020, Australian wildfires filled the air with deadly clouds of smoke and killed thousands of koalas. Around 437,000 people had to take in air with a PM2.5 concentration (浓度) of at least 25 mg/cm3 of air. That’s more than the 15 mg/cm3 of air that the World Health Organization (WHO) considers acceptable.

In the last 10 years, the total number of forest fires in China every year has increased to more than 2,000 cases. Wildfires lead to great loss of animals, forests and people. What’s worse, some animals become endangered and some people have to move to other places to live. Greater Hinggan Mountains (大兴安岭) is one of the important forestry places in China. The government uses mountain watchtowers, forest cameras and aerial drones (无人机) to prevent forest fires in summer.

文章大意:本文主要介绍不同国家为保护学生安全做了什么。

【推荐2】What do different countries do to keep students safe?

Japan

At public primary schools in Japan, earthquake training are held once a month. They teach students safety tips for earthquakes. Regular training helps students escape from earthquake-stricken areas without causing any stampedes (踩踏).

Australia

Most students in Australia take first-aid courses at school. They learn basic first-aid knowledge in the class, such as how to call an ambulance (救护车) and what to do when someone is hurt. The government is trying to make all kids take such courses.

US

Most US school buildings have fire escapes. A fire escape has platforms (平台) with stairs and ladders (梯子) at each floor of a building. They are usually made of steel and built outside of the building. People can get to the fire escape through a special fire-exit door or through a window. It is not a good idea to jump out of a window from higher than two floors. You may hurt yourself.

【推荐3】

A forest fire in south western China was under control. The fire killed 31 people. Among the victims, 27 were firefighters and four were local people.

The fire broke out on the evening of March 30 in Muli County(县), in the Liangshan Yi Autonomous Prefecture Sichuan. It began at a remote place in the tree—covered mountains at an altitude of about 3, 800 meters. The fire burned across 20 hectares as bad terrain(地形)—including the thick forest and limited water-stopped people from putting out the fire.

Following the fire in Sichuan, China issued a red alert, which is the highest level, for forest fire risks in dry northern and southwestern places. This was the first time since March 2016 that the country had issued a red alert for forest fires.

Forest fires, also called wildfires, are a worldwide problem. Wildfires are uncontrolled and can be caused by different types of weather, dry brush and wind. They burn land by the hectares and can take over everything along the way in just a few minutes.

Wildfires are either started accidentally by humans—such as a burning cigarette—or by natural causes like lightning. But these events don’t have a main effect on the scale(规模)of the fire. The warm climate from increasing greenhouse gas emissions(排放)is increasing. Studies show that over the past many years, the umber of wildfires has increased.

1. How many firefighters died in the fire in Liangshan?
A.31B.27C.3D.1500
2. Why is it difficult for people to put out the fire in Liangshan ?
A.Because the fire broke out at a remote place covered with grass.
B.Because there weren’t enough firefighters to put out the fire.
C.Because the forest was thick and water was limited.
D.Because the fire was caused by dry brush and wind.
3. What mainly affects the scale of the fire according to the passage?
A.Burning cigarette.B.Lightning.
C.The warm climate from greenhouse gas emissions.D.The number of wildfires.
4. Which of the following is NOT true according to the passage?
A.It took 31 people three days to put out the fire in Liangshan.
B.China issued a red alert to the highest level for forest fire riskd for the first time since 2016.
C.The wildfires can’t be controlled and can be caused by weather, dry brush and wind.
D.Greenhouse gas emissions increased the number of wildfires.
