六、阅读理解。

In recent years, India has suffered from more serious heat waves. From March to June every year, temperatures in many areas often rise above 43°C, and some places even hit nearly 50°C. Recently, 95 of the world’s 100 hottest cities lie in India, making it a main center of extreme(极端的) high temperature on Earth.

     ★     Geographically, India lies in tropical(热带) and subtropical(亚热带) zones. Before summer monsoons(季风) arrive, sunlight hits the land directly. The Himalayas in the north block cool northern winds, keeping hot air over the plains and forming a “heat dome” that stops heat from escaping easily . Besides, weak rainfall and the El Niño climate effect make the weather drier and hotter. Human activities make the problem worse: rapid urbanization(城市化) creates urban heat islands. More roads, tall buildings and fewer trees take in and store heat. Greenhouse gas emissions(排放) from factories and cars speed up global warming as well.

Extreme heat brings serious troubles. It harms people’s health greatly. Outdoor workers, elderly people and kids easily get heatstroke or heat exhaustion(虚脱). High electricity use for cooling often causes power cuts, which worsens water shortages. Crops like wheat grow poorly under extreme heat, leading to lower harvests. Long dry weather also raises risks of droughts across farmlands .

To fight heat waves, India has taken useful steps. Local governments send early heat warnings to the public and build cooling centers for people to rest. Workers are ordered to avoid working during the hottest noon hours. Tree-planting projects expand city green areas to lower local temperatures. In the long run, cutting carbon pollution and developing clean energy can slow global warming effectively.

 India’s repeated heat waves are a clear warning of climate change. Extreme weather is no longer distant news. If we protect forests, control pollution and live a low-carbon life together, we can cool our planet and build
