有时动词不定式作表语可以省略to 如 all i did was study hard中 did 是实意动词 was是be动词 study是实意动词出现了三个动词并存的情况
不定式作表语与 to 的省略
当不定式用作表语时,其中的 to 原则上是不能省略的.如：
His aim is to do two years’ work in one.他的目标是一年干两年的工作.
This wall is to keep people out of the garden.这堵墙为的是不让人到花园里来.
但有一种例外,那就是当主语部分有动词do的某种形式时,用作表语的不定式可以省略to.如：
What you first do is (to) mix the egg with flour.你先得把鸡蛋和面粉和好.
All I did was (to) touch the window,and it broke.我只不过碰了一下窗户,玻璃就碎了.
