Cindy wanted to paint a picture of the park near her home.

Infinitive
（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）。
（注：动词不定式没有人称和数的变化，在句子中不能做谓语。）
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);dare (敢于); 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)。
为了便于记忆，我们可用以下口诀:
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 us.
他同意帮助我们。
My parents offered to take us around the teahouse.
我的父母主动提出带我们去参观茶馆。
We all hope to see the great musician.
我们都希望见到那位伟大的音乐家。
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 don’t know what to do.
我不知道该怎么办。
I haven’t decided how to go there.
我还没决定怎样去那里。
The map can show you where to go.
这张地图可以告诉你往哪走。
用法二：

_____________(want/help) her in some way. When we arrived, Vivien was very happy. She(3)_____________(begin/talk) to me about her school. She said, “I (4)__________(like/go) to school, but I don’t have any friends. I feel lonely.”
Mum gave her some advice. Then Mum asked me to give Vivien her present, but I (5)_____________ (forget/bring) it! Vivien said, “It’s OK. I (6)___________ (hope/see) you again soon.”

Things to remember
