英语 我有两个问题 (12 17:47:28)
1.The  workers  were  made --------  ( work )   the   whole   day. 
2.怎么区别句子开头用不定式还是--ing形式?

Answer 1

1.to work
动词make后面的宾语补足语如果是动词不定式,则省略to;但是一旦在被动语态里,这个to还是要加的.
2.动词不定式或动名词在句首作主语时,不定式表示一次具体的动作；动名词表示某种动作的称呼,没有动作,只是说到某种名称、概念等.
To swim in this river is quite dangerous.
Swimming is my favourite sport.
