6.Too much water _________ in the world every day.We should save it.( 。
A.is wastedB.wastesC.was wastedD.is wasting

分析 每天全世界浪費(fèi)很多水.我們應(yīng)該節(jié)約用水.

解答 答案:A
根據(jù)題干中的時(shí)間狀語(yǔ)為every day,故確定為一般現(xiàn)在時(shí)態(tài),結(jié)合選項(xiàng)可知主語(yǔ) water 是謂語(yǔ)動(dòng)詞waste的承受者二者形成被動(dòng)關(guān)系故確定為被動(dòng)語(yǔ)態(tài),故該句的謂語(yǔ)動(dòng)詞為一般現(xiàn)在時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)其結(jié)構(gòu)為am/is/are+及物動(dòng)詞的過(guò)去分詞.主語(yǔ)water是不可數(shù)名詞只有單數(shù)形式,故主語(yǔ)是第三人稱單數(shù),be動(dòng)詞用is,waste的過(guò)去分詞為wasted,故填is wasted,故選A

點(diǎn)評(píng) 本題主要考查時(shí)態(tài)和語(yǔ)態(tài),當(dāng)句子的主語(yǔ)是動(dòng)作的承受者時(shí),應(yīng)該用被動(dòng)語(yǔ)態(tài),本題考查的是一般現(xiàn)在時(shí)態(tài)的被動(dòng)語(yǔ)態(tài).一定注意其構(gòu)成形式,一般現(xiàn)在時(shí)的被動(dòng)語(yǔ)態(tài)的構(gòu)成:am/is/are+及物動(dòng)詞的過(guò)去分詞.

4.After two weeks of meetings in Paris,195countries reached an agreement on December 12to do with climate(氣候) change.It's the first time in history that most of the world's countries,rich or poor,agreed to take action.The agreement sets the long-time goal of making sure the world temperature does not get 2°C higher than the levels in the 1800s.Otherwise there will be serious problems on Earth like natural disasters.
The agreement also asks countries to volunteer to make promises based on each country's economy(經(jīng)濟(jì)),politics and technology.For developed countries,they will do even more.They have a plan to offer over 100billion (about 647billion yuan) to help poorer countries develop clean energy like water and wind power.
Besides,there are some legally binding (法律約束的) rules.Those countries need to set national goals for cutting greenhouse gas emissions (排放) every five years.And they will publicly report their progress every five years starting in 2023.
However,the Paris Agreement alone won't solve the climate change problem.The future depends on how well each country will carry out their promises.
