It's a waste of time这个句型,急,
It's a waste of time 后面加to do sth还是doing sth?
到底哪个正确呢?还是两个都有?
答
后面接doing，固定搭配
答
分析一下句子结构你就明白了：It是形式主语，并非真正的主语。to do sth 或 doing sth 才是真正的主语。所以两者均可。It's a waste of time＋to do sth / doing sth 可以改为这种比较易懂的形式：
to do sth /doing sth is a waste of time 例如：
It's a waste of time watching TV=Watching TV is a waste of time.=It's a waste of time to watch TV.=To watch TV is a waste of time .不知你明白了吗？
答
我叫得两个都可用...
答
DOING
答
用doing sth.
最简单的理解办法就是做什么事情是浪费时间，并不是要浪费时间去做什么事情.
答
加doing sth
这个比较特殊
答
It + be + 名词词组+doing sth 固定搭配
It + be + no + 名词+ doing sth
答
to do sth
答
it is a waste of time doing
