一、不定式作宾语用法
不定式是英语中的一种动词形式，可以充当句子中的宾语。它的使用方式有以下几种：
1、 动词+ 不定式
在某些动词后面，我们可以直接跟一个不定式作为宾语。这些动词包括希望hope、想要want、决定decide、计划plan等。例如：

He wants to become a doctor.他想成为一名医生。
They decided to go on vacation.他们决定去度假。
She plans to start her own business.她计划开始自己的事业。
2、 动词+宾语+不定式
有一些动词后面需要跟一个宾语和一个不定式，构成动词+宾语+不定式的结构。这些动词包括让let、看见see、听到hear、感觉feel等。例如：
My teacher let me use his computer.我的老师让我用他的电脑。
I saw him leave the room.我看到他离开了房间。
She heard the children singing in the park.她听到孩子们在公园里唱歌。
I felt the floor shake during the earthquake.我感觉到地板在地震时摇晃。
3、 动词+疑问词+ to
有一些动词后面跟一个疑问词如what、how和to构成的不定式。这些动词包括问ask、知道know、想知道wonder等。例如：
