杭州湾大桥谁设计的:used to与be used to的用法区别？

区别1、used to do解释成“过去常常做某事”，后面接动词原形。

例：I used to play basketball.我过去常常打篮球。

区别2、am/is/are used to doing解释成“现在习惯做某事”。

例：I am used to playing basketball.我习惯打篮球。

区别3、was/were used to doing解释成“过去习惯做某事”。

例：I was used to playing basketball.我过去习惯打篮球。

区别4、be used to do解释成“被使用去做某事”。

used to do sth.过去常常做某事,(意思现在不做了)。

be used to doing sth / be used to sth .是指习惯于做某事.(这里的to 是介词.)

动词不定式形式：

1、 现在式：一般现在时表示的动词，有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后。一般为：动词+ to do something

He seems to know this.

2、完成式：表示的动作发生在谓语动词表示的动作之前。

3、进行式：表示动作正在进行，与谓语动词表示的动作同时发生。

一般在表示情绪的动词后加to do也表将来

（语态）动词和参与此动作的主语之间关系的一个术语。当主语是动作的发起者（或之一）时，称为主动语态；

如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。如：

It's a great honour to be invited to Mary's birthday party.（不定式作主语是被动语态to be invited是被邀请）

It was impossible for lost time to be made up.（不定式作主语）

I wish to be sent to work in the country.（不定式作宾语）

Can you tell me which is the car to be repaired?（不定式作定语）

He went to the hospital to be examined.（不定式作状语）

My work is to clean the room every day.（不定式作表语）

在There be结构中，修饰主语的不定式可用被动，也可用主动。如：There are still many things to take care of (to be taken care of).但有时两种形式表达的意思不同，如：There is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)
