当句子中已经有谓语动词，而我们又要表达不止一个动作概念时，其余的用词可以使用非谓语形式。
动词不定式是动词的一种非谓语形式，其基本形式是“to+动词原形”。
动词不定式在句子中不充当谓语，因此没有人称和数的变化，可在句中充当多种成分，如主语、宾语、宾语补足语和状语等。

When we arrived at the zoo, the pandas started to come out of their home. I liked one of the pandas most. That panda was full of energy. He began to eat bamboo for breakfast. After that, he tried to exercise. A few minutes later, he decided to climb a tree. He even wanted to climb over the wall!
Simon wrote about a giant panda. Read his article and pay attention to the use of to-infinitives.
Work out the rule!
We often use to-infinitives after these verbs: _____, _____, _____,_____, _____,learn, plan, prepare, choose, fail, remember, forget, agree, etc.

Grammar 1
We love the baby panda very much. We prepare all kinds of food
to give her a healthy diet. We buy toys to make her happy.
We also plan to give her a special cake and some gifts to celebrate her birthday.
Read the text below by a panda keeper and pay attention to the use of to-infinitives.
Work out the rule!
We often use to-infinitives to express purpose. We can also use in order to ecpecially in formal writting.
What can you find？
What do they express？
to + verb
The express purpose.
1) She is running quickly in order to catch the first bus.
2) They spoke softly in order not to wake the baby.
3) They left early in order to get there in time.
为了赶上首班公交车，她正飞快地跑着。
为了不吵醒婴儿，他们轻声说话。
为了使表达更加清楚或者对目的加以强调时，还可以用结构“in order to+动词原形”，意为“以便，为的是”，其否定形式为“in order not to+动词原形”。
由in order to引导的目的状语，既可以置于句尾，也可以置于句首。
为了及时赶到那里，他们很早就出发了。
= In order to get there in time, they left early.

动词不定式
做宾语补足语
1) I want you to sing a song to us.
2) My father asked me to clean my room.

动词不定式可以作宾语补足语，用来说明宾语的情况，表示宾语的状态、特征、身份等。
结构为：“动词+宾语+动词不定式”。
动词不定式做宾语补足语
