例句:I used to cut fruit with the knife which is used to cut meat, so now I am used to eating fruit with the flavor of meat.

直译:我过去常常用切肉的刀来切水果,所以现在我习惯于吃带肉味的水果了解析:1.used to do sth.表示“过去常常做某事”变否定句既可以在used的前方加didn't,也可以在used后方加not.

I used to be short, but now I am tall.

我过去很矮,但是现在很高。

He used to be afraid of dark, didn't he? / usedn't he?

他过去很怕黑,不是吗?

be used to do sth.表示“被用来做某事”,这是一个完整的被动语态形式。to do可以用介词for来替换,be used for sth.

Knives are used to cut fruit.

刀用来切水果。

Knives are used for cutting.

刀用来切东西。

be used to doing sth.表示“习惯于做某事”,此处的to是一个介词,介词后一律加动词的ing形式。

I am used to walking along the river after dinner.

我习惯于饭后沿着河边走一走。

PS:常见的to是介词的短语。

be accustomed to doing

devote oneself to doing

look forward to doing

pay attention to doing

prefer doing to doing。

be used to doing :
be used to doing sth.结构中,used为形容词“习惯的”,意为“习惯于做某事”。be可以用become, get等来代替,在意义上相当于accustomed to“习惯于”。同时结构中的to是介词,后面跟名词、代词或动名词。

例如:Lucy got used to living in the countryside.他们已习惯于住在城市。

used to do:意为: 过去常常……

例句:Life here is much easier than it used to be.

    这里的生活比以前的更容易。

    We used to go there every year. 

    我每年都去那儿。
