三、阅读理解（30分，每题2分）
A
Global warming is a big threat to our planet. It happens when the Earth's atmosphere traps too much heat from the sun. This is mainly caused by greenhouse gases, which come from burning coal, oil and gas.
One of the main effects of global warming is the rise in temperature. Over the past 100 years, the Earth's average temperature has increased by about 0.8℃. This may not seem like much, but it has a big impact.
Another effect is the melting of glaciers and ice sheets. This causes sea levels to rise, which can flood low - lying areas. Many small islands and coastal cities are in danger of being underwater in the future.
Global warming also changes weather patterns. Some areas get more rain, leading to floods, while others get less rain, causing droughts. This affects agriculture and food production.
26. What causes global warming mainly
A. Too much heat from the sun. B. Greenhouse gases from burning fossil fuels.
C. Melting ice sheets. D. Changing weather patterns.
27. How much has the Earth's average temperature increased over the past 100 years
A. About 0.8℃. B. About 1.8℃. C. About 2.8℃. D. About 3.8℃.
28. What happens when glaciers and ice sheets melt
A. Temperature rises. B. Sea levels rise. C. Weather patterns change. D. Floods happen.
29. How does global warming affect weather patterns
A. Some areas get more rain, others get less. B. All areas get more rain.
C. All areas get less rain. D. Weather patterns don't change.
30. What is the main idea of the passage
A. The causes of global warming. B. The effects of global warming.
C. How to stop global warming. D. The history of global warming.
B
There are many things we can do in our daily lives to fight global warming. Here are some simple tips:
Save energy at home: Turn off lights, TVs and computers when you're not using them. Use energy - saving light bulbs. They use less electricity and last longer.
Reduce, reuse, recycle: Reduce the amount of waste you produce. Reuse things like plastic bottles and bags. Recycle paper, glass and plastic. This reduces the need for new materials and saves energy.
Use clean transportation: Walk, bike or take public transport instead of driving a car. If you have to drive, try to carpool with others. This cuts down on greenhouse gas emissions.
Plant trees: Trees absorb carbon dioxide, a major greenhouse gas. You can plant trees in your garden or join a tree - planting project in your community.
31. What can we do to save energy at home
A. Turn off lights when not in use. B. Use energy - saving light bulbs.
C. Turn off TVs and computers when not in use. D. All of the above.
32. What does “reduce, reuse, recycle” mean
A. Produce more waste. B. Reuse things and recycle materials.
C. Throw away all waste. D. Buy new things instead of reusing old ones.
33. Why is using clean transportation helpful
A. It saves money. B. It reduces greenhouse gas emissions.
C. It's more convenient. D. It's faster.
34. How do trees help fight global warming
A. They produce oxygen. B. They absorb carbon dioxide.
C. They provide shade. D. They prevent flooding.
35. What is the passage mainly about
A. The causes of global warming. B. The effects of global warming.
C. Daily actions to fight global warming. D. The importance of global warming.
C
The polar bear is one of the animals most affected by global warming. These beautiful creatures live in the Arctic, where they depend on sea ice to hunt seals.
As global warming causes the Arctic ice to melt, polar bears are losing their hunting grounds. They have to swim longer distances to find ice, which uses up a lot of energy. Many polar bears are becoming weak and hungry, and some even die.
Scientists predict that if global warming continues at its current rate, two - thirds of the world's polar bears could disappear by 2050. This is a sad reality that we need to face.
But there is hope. If we take strong action to reduce greenhouse gas emissions, we can slow down the melting of Arctic ice. This would give polar bears a better chance to survive.
Protecting polar bears is not just about saving one animal. It's about protecting the whole Arctic ecosystem and our planet. We all have a role to play.
36. Where do polar bears live
A. In the Antarctic. B. In the Arctic. C. In forests. D. In deserts.
37. What do polar bears depend on to hunt seals
A. Sea ice. B. Water. C. Land. D. Snow.
38. Why are polar bears becoming weak and hungry
A. Because they can't find enough food.
B. Because they have to swim longer distances to find ice.
C. Because their habitat is destroyed.
D. All of the above.
39. What will happen to polar bears by 2050 if global warming continues
A. They will all disappear. B. Two - thirds of them could disappear.
C. Their numbers will increase. D. They will move to other places.
40. What can we do to help polar bears
A. Reduce greenhouse gas emissions. B. Ignore global warming.
C. Hunt polar bears. D. Destroy their habitat.
