2、只能用一般过去时，不能用现在时态。【用法】1. 它的陈述句的肯定形式：主语used to动词原形。I used to play with my friends after school. 过去放学后我常常和朋友们一起玩。2. 它的否定形式：主语didntuse to动词原形。You didnt use to like pop songs. 你过去常常不喜欢流行歌曲。3. 它的一般疑问句形式：Did主语use to动词原形其他？Did your sister use to be quiet? 以前你的妹妹常常是很安静的吗？4. used to的状语可以用副词always，often，someti

3、mes等，但是仍然是过去的习惯，不是指现在的习惯，所以不能用一般现在时。He always used to be late for class. 他过去常常上课迟到。5. used to可以用在there be结构中表示“过去经常有”的意思。There used to be a lot of fish in this river. 过去这条小河常常有许多鱼。【拓展】1. be used to （doing） sth.意为“习惯于（做）某事”，可用于各种时态，其中to为介词，used为形容词，to后可接名词、代词或动词-ing形式。Are you used to the wet weather

4、here? 你对这儿的潮湿天气习惯吗？Mr. Li is used to washing his face with cold water. 李先生习惯于用冷水洗脸。2. be used to do sth.意为“被用来做某事”，其中used为动词use的过去分词，to为不定式符号，应接动词原形。This knife is used to cut bread. 这把刀子是用来切面包的。【考题链接】My father is used to _early now.A. get up B. getting up C. got up D. gets up答案：B思路分析：be used to +v.-

5、ing形式，意为“习惯于做某事”；be used to do sth.意为“被用来做某事”；由主语是my father，可知本句是主动语态，A项错误；句意为“我父亲现在习惯于早起床了”，故B项符合句意及语法点。1. Usually computers _ to search the Internet. A. use B. are using C. are used D. used2. My mother _ us stories when we were children. A. was used to tell B. is used to telling C. used to tell D.

6、 used to telling 3. _ used to_ an old bookshelf in my room. A. There; be B. There; have C. It; be D. There; having 答案：1-3 CCA思路分析：1. usually通常是一般现在时态的标志词，D项是过去式，故错误；根据句意“电脑通常被用来上网”可知用被动语态，故排除A, B两项。2. 从本句意思“我妈妈过去常常给我们讲故事，”可以理解为是用“used to动词原形”表示“过去常常”。3. 本句是考查there be和used to连用的用法，表示“过去常常有”的意思。（答题时间：
