3a-Self CheckUnit 4I used to be afraid of the dark. 1. “used to+不定式”表示过去干某事, 现在不再干了。 eg. I used to go to work by bus. Now I take a taxi. She used to be very shy. Revision 2. used to 可用存在句。例如：There used to be a cinema here before the war. 战前这儿有一家电影院。3. 在否定句和附加疑问句中，可以用usedn’t (used not)，也可以用didn’t。例如：He usedn’t / didn’t use / used not to smoke. 他过去不抽烟。 He used to live here, didn’t / usedn’t he? 他过去住在这里，不是吗？be (get) used to be used to中的to是个介词，和used to不同。该词组的含义是“习惯……”。所以to后面不能接动词原形，而要接名词或v-ing形式。 例如： They are used to the hard work here now. 他们现在习惯这里的艰苦工作了。 I’m used to dealing with matters of this kind. 我习惯处理这类事情了。The mother traveled for many hours to return home to talk to her child_____________.
