used 的词组区别
解题思路: 学习时可通过典型的例句加以比较,可通过短语的意思、主被动、句式等加以区别。
解题过程:
一、 be used to do sth.
be used to do sth. 表示“被用来做某事”。如:
This computer is used to control all the machines. 这台电脑是用来控制所有机器的。
二、 be used to doing sth.
be used to doing sth.表示“习惯于做某事”,其中to是介词,后接名词或动名词。如:
The old man and his wife have been used to living a simple life. 这对老夫妇已经过惯了简朴的生活。
I am not used to my new job. 我不习惯我的新工作。
Is she used to walking after supper? 她习惯晚饭后散步吗?
be used to还可用get used to表示“渐渐习惯于……”。如:
You'll get used to your new job. 你很快就会习惯新工作的。
三、used to do sth.
used to 意为“过去常常”,可看作半助动词或情态动词,其后跟动词原形,表示过去的习惯、经常发生的动作或状态。如:
He used to be a teacher in our school. 他曾经是我们学校的一位老师。
There used to be an old temple near the village. 过去村子的附近有一座古庙。
used to的各种句式:
1. used to用于疑问句时有两种句式,即Did sb. use to do ... ?和Used sb. to do ... ?如:
Did he use to go to the concert? 他过去常去音乐会吗? = Used he to go to the concert?
肯定回答:Yes, he did. 否定回答:No, he didn't.
2. used to用于否定句时也有两种句式,即didn't use to和used not to。如:
I didn't use to play football. 我过去不踢足球。 = He used not to play football.
3. used to用于否定疑问句时也有两种形式。如:
Didn't you use to go to the library? 你过去不是常去图书馆吗? = Used you not to go to the library?
