请问老师can后面的动词不是原型吗，这两道题为什么can后面不是原型，考点是什么？

   【答】We'd like to do all we can to help the poor. 在all(that)/everything (that)/what I can (do)后面应该用带 to 的动词不定式作目的状语。在这些机构中，I can (do)是定语从句，(do)通常省略。

    I like English and I spend every minute I can studying English.

此句中的 every minute I can = every minute I can spend，其中的I can spend是定语从句，修饰every minute。这里的 I spend every minute I can studying 就是“spend + 时间 + doing”这种用法。
