题目内容
7.China used 1.2 million tons of coal for heating and gneratingelectricity last year.分析 中国去年用了120万吨的煤来供暖和发电.
解答 generating generate是一个动词,意为"形成,造成;产生(能量),发(电)",通过前面部分used 1.2 million tons of coal (用煤)可知,是用来发电的,generate electricity意为"发电",又因为前面有介词for,heat和generate作为for的两个并列宾语,都要加ing,故填generating.
点评 考查动词的词义,在熟记单词词义的基础上还要联系语境,从而写出正确答案,写动词时还要注意其人称、时态和语态的变化.
