Plastic brings us convenience, and pollution as well. 【小题1】 It’s in our food and drinks, in the clothes we wear and even in the air we breathe.

Some very tiny pieces of plastic are called microplastics ( 微塑料). The largest microplastics can be directly seen. 【小题2】 What should we do then?

【小题3】 Any time plastic boxes are heated, microplastics can get into your food. If you can’t avoid using plastic boxes, try not to heat food in them.

Use a glass or metal cup instead of a plastic one. Researchers have found that bottled water has more microplastics than tap water. 【小题4】 So if you like drinking coffee, hot milk or other hot drinks, remember to use a glass or metal cup.

Since plastic is everywhere, researchers suggest that we should be careful with possible microplastics in life. They may be from baby toys, pens, and even phones we use every day. 【小题5】

A．What’s worse, it’s everywhere.

B．Avoid heating food in plastic boxes.

C．Use plastic products widely in our daily life.

D．Also, the heat of your drinks will encourage microplastics to get into your drinks.

E．All in all, we should use plastic products properly.

F．But many of them are small enough to be around us without being seen.

Air is important to us. 【小题1】 We live in air but we cannot see it. We can only feel it. 【小题2】

Sadly, the problem of air pollution is getting serious(严重的) today. Air pollution is bad for people’s health. 【小题3】 What’s worse, air pollution makes the Earth become warmer and changes the weather around the world. It’s really important for us to do something and stop the problem from getting worse. We should try to drive less. 【小题4】 Also, we should reduce(减少) the waste in our daily lives because the burning of rubbish pollutes the air. 【小题5】

A．It makes us get sick easily.

B．We can feel it when it is moving.

C．Try to find a new way to use the old things again instead of throwing them away.

D．If we need to go to a place far away from us, we should take the bus or the underground.

The Amazon rainforest covers 5.5 million square kilometers. That’s about half the size of China! However, according to a new study, the Amazon rainforest may become grassland (草原) in a few years.

The Amazon is the world’s biggest rainforest. Climate change and human activities make it “sick”. Usually, the rainforest can fix itself. But now, it feels too “tired” to get better. The trees may die and the rainforest could turn into a hot, dry grassland.

Why is the Amazon “sick”? The Amazon is one of the world’s wettest places. But since 2005, three droughts have hit the rainforest. They were caused by climate change. The trees don’t have enough water to grow. What’s worse, as they become dry, they can easily catch fire.

On the other hand, people cut down rainforest trees for wood. They burn the forest to make farmland. They clear trees to find minerals (矿产). All these activities have caused about 17 percent of the rainforest to disappear.

The Amazon is like the lungs of our planet. The rich plants there take carbon dioxide (CO₂) out of the air and make oxygen. They make more than 20 percent of the planet’s oxygen. What will happen if we lose it? If the Amazon “dies”, there will be more CO₂ and our earth will become even hotter.

Also, the Amazon is home to over 3 million animals and plants. Many of them can’t live anywhere else. They would very likely just disappear.

【小题1】If the rainforest can’t fix itself, what will the rainforest turn into?

【小题2】What does “they” refer to in Paragraph 3?

A．The trees.

B．The three droughts.

C．The rich plants.

D．The world’s wettest places.

【小题3】What will our earth be like if the Amazon “dies”?
