Talking mends no holes. 

（谚）空谈无济于事。

注：

1)动名词作主语时用it作形式主语，把动名词放到句子后面。常见句型:
①It'+adj(useless,hopeless,nice, good,interesting, expensive,worthwhile) + doing sth．

②It's+adj(no use, no good ,fun, a great pleasure, a wonder, a waste of  time) +doing sth. 
例:

2、动名词作表语：
Her job is washing and cooking.      My hobby is collecting stamps.

2) 有些动词可以用动名词作宾语，也可以用不定式作宾语，
（1）两者意思不同

动名词多表示习惯或经常的情况，不定式多表示即将发生或具体一次的事：

She dreads seeing them.  

I dread to think what may happen.
有时两者可以换用，意思上没有差别：

区别： 在begin，Start，不定式多表示情况发生变化,而动名词表示有意识地开始或停止.
Suddenly it started to rain.天突然下起雨来。 Philip began to cry.菲利普哭了起来。
We began making preparitions for the trip.我们开始作旅行的准备。
注意:在以-ing结尾的动词后不宜再用动名词，以避免-ing的重复：
