Iliketoplaycomputergames为什么要加to？

推荐回答

这是英语文法规则游戏。

加 to 不加 to  是有文法管制, 不是隨心所欲, 心情不好就加, 好就不加那样子的。

加与不加也都是祢为不定词。

这句子必須加, 不能省略。

因主要观察点是, 前面动词是什么而决定。若果, 不定词前面的动词是 :  hear, see, dare, need, make, let, bid ; 又或 shall, will, do, should, would, may, might, must, can, could ; 又或 had better, had rather, would rather, sooner than, rather than ..

这样,  to 可省略。 

举些例子 :

I need not let her go.

We must go.

I can swim.

I hear you speak well.

She heard me cry.

He would rather die than live with you.

以上句子就是明显省略了 to 。
