Infinitives
（不定式）
Presentation
Infinitives
（不定式）
定义：
主要行为动词后面的动词都采用了”to+动词原形”的结构（有时可以不带to）。
动词不定式没有人称和数的变化，在句子中不能做谓语。
Presentation
用法一：
不定式作宾语是及物动词后带to的不定式，表明意图、希望或决定的内容等。我们常见的动词+ to do sth. 的结构主要是动宾结构。
通常只能接不定式作宾语的动词有：agree (同意); offer (提出); intend， plan (打算，计划); demand， ask (要求); promise (答应); help (帮忙); prepare (准备); decide (决定); refuse (拒绝); choose (选择); wish，hope，want， expect (希望，想要); fail ;(不能;忘记); pretend (假装); manage (设法); determine (决心)。
Presentation
助记口诀
同意提出做计划， 要求答应来帮忙。
准备决定遭拒绝， 敢于选择有希望。
不能做到莫假装， 设法做成决心坚。
He agreed to help the kids with painting.
The kind girl offered to take some food to the nursing home.
We all hope to raise more money for the sick kids.
Presentation
Some verbs can have other verbs after them. We usually use to before the second verb. We call these second verbs infinitives.
Three teenagers offered to do some voluntary work during the school holidays.
Cindy wanted to paint a picture of the park near her home.
Work out the rule
An infinitive is the (base/ -ing/ -ed) form of a verb.
Infinitives
We can use verbs +to + infinitives in sentences.

Let’s talk about the pictures
特殊疑问词与不定式常连用作宾语，在功能上相当于一个宾语从句，但不能构成复合宾语。这些词为:know, decide, ask, forget, get, remember, like, learn, think, tell, want, wish, advise, show等。
I can’t decede when to visit the children’s hospital.
The teacher can show you how to raise more money.
用法二：

decide learn plan wish
We often use to + infinitive after these verbs:
We can use question words + to + infinitives after decide, know,
learn and remember.
Do you know how to help disabled children
Things to remember

Reflection
做志愿工作最宽泛，也可能是最有意义的定义是：在一份你认为好的事业中，因为想要做而做的比你应该做的事情多。
—伊凡 席勒（美国志愿服务领域真正的先驱之一）
“The broadest, and maybe the most meaningful definition of volunteering: Doing more than you have to because you want to, in a cause you consider good. ”
– Ivan Scheier(one of the true American pioneers of the field of volunteerism)
