非谓语动词选择题,请详解.
Everyone here will thank the firefighter for the things they have done to prevent fires and ______ (make) the environment safer .
to make 是对的.
to prevent fires (“预防火灾”)的目的是to make the environment safer,这里的to make the environment safer是做目的状语的,和to prevent fires并列.
此处切勿受到prevent的干扰.
另外,此处的不定式符号to因为是句中的第二个不定式,to也可省略,直接用make
再问: 那道题和这道题不一样……我的多了个and
再答: 哦。那此处的(to) make the environment safer 和to prevent fires并列关系,因为把to prevent fires去掉后意思基本不变。
再问: to是否要省略?
再答: 可以省略,如: It’s necessary for us to read more and have more practice. He didn’t want to go on working but have a rest.
