（新版）英语九年级单元练习题解析 Unit 4 I used to be afraid of dark. 一、单项选择 ( )1. She _____ fat, but now she is thin. A. used be B. used to be C. used to being D. was used to be 解析：此题主要练习used to的用法 used后不能直接带动词原形，排除A；used to（过去经常）中的to为不定式小品词，之后应带上动词原形，排除C；be used to的主语为表人的词语时，意为“习惯于…”，to为介词，之后的非谓语动词应使用-ing形式，排除D。 知识要点：1、used to的用法：用于表示“过去经常做某事”，之后带动词原形。用于说明过去习惯性的动作或状况，常暗示与现在有明显的区别，只用于说明过去时态。其疑问和否定式可借助于助动词did，也可直接用used构成。 e.g He used to play football, but now he plays the guitar. There used to be a football match in our school on Friday afternoon. Did you use to be afraid of the dark? = Used you to be afraid of the dark? I didn’t use to play the piano. But now I’m good at it. I used not to play the piano. But now I’m good at it. 2、be used to s.th/doing s.th：“习惯于……”，to为介词，之后带名词或动词-ing形式，句子的主语应为表人的词语。 e.g The Browns are used to the weather in our city. I am used to learning English by watching English videos. 3、be used to do s.th：“被用来做什么”（= be used for doing s.th），use的被动语态结构，to为不定式的小品词，其后带动词原形，句子的主语应为表物的词。 e.g Knives are used to cut things. = Knives are used for cutting things. ( )2. We are _____ English by watching English-speaking movies. A. used learn B. used learning C. used to learn D. used to learning 解析：此题主要练习词语用法区别 be used后不能直接使用动词原形或-ing形式，排除A/B；be used to的主语为表人的词语时，to为介词，之后的非谓语动词用-ing形式，排除C。 ( )3. Do you know that this kind of machine is _____ shoes? A. used make B. used making C. used to make D. used to making 解析：此题主要练习词语用法区别 be used后不能直接使用动词原形或-ing形式，排除A/B；be used to的主语为表物的词语时，to为不定式小品词，之后带动词原形，排除D。 ( )4. She _____ use to be outgoing in her class, but now she makes lots of friends. A. didn’t B. doesn’t C. wasn’t D. isn’t 解析：此题主要练习used to的用法 动词be后的动词不能使用动词原形，排除C/D；use后不能直接带不定式，只有说明“过去经常”的used to可带动词原形，因此此处的use原应为used，变为否定句式，应借助于助动词did，排除B。 ( )5. Could you tell me _____ we can do with our problems in school? A. who B. what C. where D. how 解析：此题主要练习句式结构同wh-词的关系 宾语从句中的动词do为及物动词，在此同with构成固定短语时，do之后应带上宾语
