题目内容

【题目】When someone ________ (thank), it more than doubles his or her chances of being helpful again.

【答案】is thanked

【解析】

句意:当一个人被感谢后,他或她再次帮助人的可能性会成倍增加。

根据下句it more than doubles his or her chances of being helpful again. 他或她再次帮助人的可能性会成倍增加可知,时间状语从句的主语someonethank之间是被动关系;又根据下文中的doubles可知,从句应用一般现在时的被动语态,其构成形式为be+donesomeone是第三人称单数形式,所以助动词应为isthank的过去分词为thanked,故答案为is thanked

【题目】 A new rubbish sorting system (垃圾分类系统) has been put into use in Fangchengyuan Community in Beijing. Local people not only sort their rubbish, but also put QR codes (二维码) on it.

"When the rubbish is collected and the codes are seen, I will get reward points to exchange for small gifts and even some money," one of the local people told reporters. "It's really creative and encouraging."

This smart system has been carried out in 350 communities in Beijing. The capital of China has joined a list of cities in the country that take action to support rubbish sorting. For example, Shenzhen and Shanghai have made laws to punish people and organizations for not sorting rubbish correctly.

China produces quite a lot of rubbish every year. Much of the rubbish is buried in soil or burned without being sorted. Landfills (填埋场) take up a lot of land and have a risk of polluting the soil and water nearby. And burning rubbish can produce harmful gases. Through rubbish sorting, we can reduce the use of landfills and air pollution.

What's more, rubbish sorting saves resources, which could bring economic benefits (经济利益). For example, a ton of waste paper can be reused to make about 850 kg of paper, saving 17 trees and 50 percent of water. Because of their benefits, some countries have developed successful sorting systems.

Japan has a strict and detailed system. When people throw away a water bottle, the cap, the wrapper (包装纸) and the bottle itself have to go into three different bins. Every year, families receive special rubbish sorting timetables and directions from their local governments. They are advised to follow the timetables and directions when they throw away rubbish.

In Australia, every family is provided with three rubbish bins -the red lid (盖子) bin for "general waste" like food and plastic bags, the yellow lid bin for "recycling" like steel and glass, and the green lid bin for "green waste" such as grass and leaves. On the streets, the bins are printed with pictures of the things that are allowed inside. It makes recycling quite easy.

1Which of the following is NOT the consequence (后果) of burying rubbish?

A.Polluting soil.B.Polluting water.

C.Taking up a lot of land.D.Saving resources.

2Which paragraph discuss the economic benefits of rubbish sorting?

A.Paragraph 3.B.Paragraph 4.

C.Paragraph 5.D.Paragraph 6.

3In Australia, which bin should you put food left after dinner in?

A.The red lid bin.B.The yellow lid bin.

C.The green lid bin.D.The black lid bin.

4Which of the following is TRUE according to the text?

A.In Australia, the green lid bin is used for all kinds of recyclable (可回收的) waste.

B.In Japan, all kinds of things for recycling are printed on rubbish bins.

C.Japanese people cannot throw a bottle into a bin unless they move away the wrapper first.

D.Australian people have to obey local timetables and directions to throw away rubbish strictly.
