阅读短文，选择正确答案：
Global warming is one of the most serious problems facing the world today. The Earth’s temperature is rising because of the increase in greenhouse gases, such as carbon dioxide. These gases come from human activities like burning fossil fuels for energy.
As a result of global warming, the climate is changing. Glaciers are melting, and sea levels are rising. This puts many coastal cities and small island countries at risk of being flooded. In addition, there are more extreme weather events. Droughts are becoming more common in some areas, while floods hit other places more often.
We need to take action to stop global warming. Using renewable energy sources like solar, wind, and hydro power can reduce the use of fossil fuels. Recycling, saving water and electricity, and reducing waste are also important steps. Every small action we take can make a difference in protecting our planet.
1. What is the main cause of global warming
A. The decrease of greenhouse gases. B. The increase of greenhouse gases.
C. The melting of glaciers. D. The rising of sea levels.
2. What problems does global warming bring
A. Only the melting of glaciers. B. Only the rising of sea levels.
C. Melting glaciers, rising sea levels and more extreme weather.
D. None of the above.
3. What can we do to stop global warming
A. Use more fossil fuels. B. Throw away more waste.
