Do you still remember how to help people? We can help...

We usually use to before the second verb. We call these second verbs infinitives. Work out the rule An infinitive is the (base/ -ing/ -ed) form of a verb. Practice: Three teenagers offer do some voluntary work during the school holiday. to ^ 动词不定式 to do to+动词原形 动词 小跟班 let's open the book and turn to p7. 动词不定式的构成很简单：to do. 动词不定式是to + 动词的什么形式呀？right, base form,动词原形。那么为什么会出现动词不定式呢？我们看到书本的最上方，Some verbs...有些动词呀，它后面会跟着其他动词，就像有一个小跟班一样。这种情况下，第二个动词前我们通常会加to,就构成了我们的动词不定式。我们可以来尝试一下。同学们康康这句话对吗？它是错的。这个句子里面我们可以找到两个动词，offer 和 do. 根据我们刚刚的规则，第二个动词，也就是小跟班do前面要加一个什么呀？to。你改出来了嘛？ 不定式的用法 These three teenagers offered to do a lot of voluntary work.
