学习新单词对我来说非常重要。
⑴ It's wrth making the effrt.⑵ It is pleasant wrking with yu.⑶ It's n use crying ver split milk.⑷ It was a waste f time reading that bk.
这件事值得努力去做。
2. 有时可用it作形式主语前置,真正的主语是 -ing形式。 但这种句子形式有一定的限制,作表语的只能是某些形容词或少数名词。
常用-ing形式作主语的句型有:
It + be + a waste f time ding …It is/was n gd/pleasure/use/useless ding …It is/was hardly/scarcely wrth ding …It is/was wrth/wrthwhile ding … There is n sense in ding
做……没有用/没有意义

5. 动词-ing与动词不定式作主语的区别:动词-ing作主语,常常表示抽象的习惯性或经常性的动作。 而不定式一般表示一次性、具体性的行为。Delivering newspapers is his jb. 送报纸是他的工作。T deliver newspapers is his jb tday. 送报纸是他今天的工作。
