In recent years, some Chinese cities have been working hand on it, Shanghai has worked with Alipay to create a “green account(账户)” service for its residents(居民). Account holders get points by sorting their rubbish correctly. Through the Alipay app, they ran exchange the points for milk, phone cards and other products . The city is asking all of its residents to sort their rubbish into four groups: wet, recyclable, harmful and dry. Wet waste is also known as household waste. Paper, metal and glass are recyclable waste. Medicine and batteries are harmful waste. Finally, any waste that's not wet, recyclable or harmful will go in the "dry waste" bin. Many other Chinese cities are also doing this. Shenzhen has been sorting its rubbish into the same four groups since 2012. Students there must study waste-sorting guidebooks.If you don’t sort your rubbish， it will go to a landfill(垃圾填埋场) and be buried together. These landfills can take up large areas of ground. Some rubbish can pollute the soil and groundwater and it can also do harm to the environment around us. China is improving its waste-sorting efforts. There is still a long way to go.1.How should we deal with all kinds of rubbish A．We can throw them all into one binB．We can sort them separately.C．We can throw them away freely.D．We can reuse them all2.How is Shanghai encouraging people to sort their rubbish A．By creating a "green account" service with the help of Alipay.B．By paying people to sort their rubbish correctly.C．By allowing people to exchange rubbish with each other.D．By providing its residents with guidebooks to help them3.Which of the following things belong to harmful waste A．Leftover food and batteries.B．Metal and medicine.C.

Paper and glass.4.What is the main idea of the last paragraph A．Where we can bury our waste.B．Why we should sort our rubbish properly.C．What kinds of waste can pollute the environmentD．How some kinds of waste can be reused and recycled.5. What do we know about rubbish sorting in China A．Shenzhen has been sorting its rubbish for 10 years.B．All the students have to take waste-sorting classes at schoolC．As for rubbish sorting, we Chinese still have much work to do.D．Burying is the only way of dealing with rubbish三、六选五Want to save the earth Plant a tree.What’s causing global (全球的) warming Is it man — made Or are temperatures simply changing naturally Whatever the case, we can at least try to slow things down. But how The Wilderness Project has an idea. 1 If the earth has more trees, greenhouse gases will be reduced, and this will help stop global warming. 2 They can also improve the air quality. 3 In Belgium, the Organization for Forests worked with farmers to help them plant more trees. In Spain, the Canopy Project plants one tree for every Spaniard (西班牙人) in order to improve the environment. In Germany, a teenager named Felix Finkbeiner has been leading a global movement to plant more trees. 4 Now, lots of people all over the world have already been planting more trees. In fact, if everyone plants one tree, just one, it will do great good to our environment.So what can you do to help 5 although you need to get advice on how to look after it.
