Working with you is a pleasure.
和你一起工作是一种乐趣。
动名词做主语和不定式做主语一样,也可以用it作形式主语。如:

用形式主语it,把真正的主语ing形式移置句尾。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。
和Mary争辩是没有什么用的。
It is useless arguing with Mary.
这事值得去试一试。
It’s worthwhile trying.
跟你在一起工作是令人愉快的。
It is pleasant working with you.
① It +be +no good /useless doing…
做…无益/无用
抱怨是没有用的.
②It +be +a waste of time doing…
做…是浪费时间
试图说服他就是浪费时间
③It +be +worth(worthwhile) doing …做…值得

④There +be +no +n. +in +doing …做…没有…

2. 作宾语 (动词宾语和介词宾语)

2. can’t help, feel like, object to, be busy, pay attention to, stick to, have trouble/problem (in), devote oneself to, be worth等
2.2 一些动词后加doing用于主动表被动
e.g. 这个自行车需要修了。
The bicycle needs reparing.
need, require, want(想要被……) + doing = need to be done
2.3 有些动词后既可跟doing也可跟to do做宾语,但意思不同

动名词作表语一般说明“主语是做什么的,或是怎么回事”(事/物)
四、作定语
The swimming pool belongs to our school
动名词做定语说明被修饰名词的功能或用途,一般是单个动名词,放在被修饰名词之___,可以转换成for 短语,表示“供作...之用”。
a walking stick
(a stick for walking)
a swimming pool ____________________
前
a pool for swimming
五、动名词的复合结构
如果动名词有自己的逻辑主语,这便构成了动名词的复合结构。其逻辑主语一般由物主代词、名词所有格、人称代词的宾格或名词的通格来充当。
Do you mind my/me opening the door
我打开门你介意吗?
I can’t imagine Mary’s/Mary marrying such a man.
我无法想象玛丽竟然嫁给了这么一个人。
注意:当动名词的复合结构作主语时,其逻辑主语只用所有格或物主代词表示。
The students’ knowing English well will help them to learn French.
学生学好英语对学习法语有帮助。
