语法 all she wanted to do was speak to her boys!

我偶尔也看到过这种用法。具体解释如下：作表语的动词不定式通常要带to, 但如果主语部分有（或者能使人体会到有）行为动词do（或does, did, to do, doing, done等）, 则不定式符号to可以省略。例如： The first thing she did was go up to her trainer and thank her for all her help during her training。 她做的第一件事就是走到教练面前,感谢教练在训练期间给予她的帮助。 What I want to do is have a good rest。 我所需要的是好好休息休息。 The only thing (to do) is press a button。 唯一要做的事情就是按一下按钮。
