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

分析 每天全世界浪费很多水.我们应该节约用水.

解答 答案:A
根据题干中的时间状语为every day,故确定为一般现在时态,结合选项可知主语 water 是谓语动词waste的承受者二者形成被动关系故确定为被动语态,故该句的谓语动词为一般现在时态的被动语态其结构为am/is/are+及物动词的过去分词.主语water是不可数名词只有单数形式,故主语是第三人称单数,be动词用is,waste的过去分词为wasted,故填is wasted,故选A

点评 本题主要考查时态和语态,当句子的主语是动作的承受者时,应该用被动语态,本题考查的是一般现在时态的被动语态.一定注意其构成形式,一般现在时的被动语态的构成:am/is/are+及物动词的过去分词.

4.After two weeks of meetings in Paris,195countries reached an agreement on December 12to do with climate(气候) 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(经济),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 (法律约束的) 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.
