几个不定式句子

1All you need to do is send a message with the in-network messaging service.

2 One easy way to do this is to ask him to attend events with you that you’d be going to anyway, which can make the relationships between you and your friends become stronger.

由以上两句可以看出：不定式符合to的省略

不定式做表语或做介词but的宾语时，如果前面出现了实意动词do的各种形式或情态动词，那么to可以省略。

3 For almost two years, we had owed different people for her to continue with her required chemotherapy(化疗) and medication.不定式的复合结构做目的状语。

4 Illness, injury, love, lost moments of true greatness and stupidity all occur to test the limits of your soul.

此句中的不定式to test是目的状语，并不是occur to sb/sth结构（此结构中to是介词）。

5 Hold your head up  because you have every right to.

本句是不定式的省略。to后省略了前面提到的hold your head up。

6 He will be able to express what is going on and this can allow him to let go of a lot of weight off his shoulders and to become clear about what he needs to do.
