B 解析：问句主语Ms Smart是女性，答句需用女性人称代词she指代，he（他）指代男性，I（我）指代自己，均不符合，故选B。 2. A 解析：根据“works in a police station”（在警察局工作），可知职业是警察（police officer）。postman（快递员）、coach（教练）均与工作地点不符，故选A。 3. B 解析：often是一般现在时的标志，主语he是第三人称单数，谓语动词需用helps（help的第三人称单数形式）。help（原形，主语为单数时不适用）、helping（现在分词，缺少be动词）均不符合，故选B。 4. A 解析：主语I搭配be动词am；主语they是复数，搭配be动词are。is用于第三人称单数，故B（第二空is错误）、C（第一空is错误）均不符合，故选A。 5. A 解析：so后接形容词作表语，busy（忙碌的）是形容词原形。busying（错误形式，busy的现在分词为busying，但此处无需动词形式）、busies（busy的第三人称单数，是动词形式，不可作表语）均不符合，故选A。 6. B 解析：now是现在进行时的标志，句型结构为“What are/ is sb. doing?”，主语the students是复数，be动词用are，后接动词-ing形式doing。A（结构混乱，do与does重复）、C（一般现在时，不符合now的语境）均不符合，故选B。 7. B 解析：Listen!是现在进行时的标志，结构为be+动词-ing，主语Zhang Peng是第三人称单数，be动词用is，sing的-ing形式为singing。sings（一般现在时第三人称单数）、sing（原形）均不符合语境，故选B。 8. A 解析：“带某人去某地”用固定搭配take sb. to sp.，for（为了）、at（在……）均不符合搭配要求，故选A。 9. B 解析：help是动词，后接人称代词宾格，we（主格）、our（形容词性物主代词，后接名词）均不符合，us是I的宾格形式，故选B。 10. A 解析：can是情态动词，后接动词原形，clean（原形）符合要求。cleaning（现在分词）、cleans（第三人称单数）均不可直接跟在can后，故选A。 四、词汇运用题 （A）选择正确的单词补全句子 1. am; at 解析：主语I搭配be动词am；“在家”用固定短语at home，故填am; at。 2. is; in 解析：主语Sam是第三人称单数，be动词用is；“在养老院”用in an old people's home（大地点前用in），故填is; in。 3. are 解析：主语Alice and Bob是复数，be动词用are，故填are。 4. is; at 解析：主语He是第三人称单数，be动词用is；“在儿童中心”用at the children's centre（小地点前用at），故填is; at。 5. are 解析：主语They是复数，be动词用are，结合Look!（现在进行时标志），故填are。 （B）用所给词的适当形式填空 1. tell 解析：can是情态动词，后接动词原形，故填tell。 2. reads 解析：often是一般现在时标志，主语he是第三人称单数，read的第三人称单数形式为reads，故填reads。 3. photos 解析：photo是可数名词，a lot of后接复数形式，photo的复数为photos，故填photos。 4. me 解析：show是动词，后接人称代词宾格，I的宾格为me，故填me。 5. learning 解析：now是现在进行时标志，结构为be+动词-ing，learn的-ing形式为learning，故填learning。 6. are; doing; are making 解析：now是现在进行时标志，问句结构为“What are sb. doing?”，主语the students是复数，be动词用are，do的-ing形式为doing；答句主语they是复数，be动词用are，make的-ing形式为making，故填are; doing; are making。 7. Those 解析：“那些”的英文为Those，用于指代复数名词，句首首字母大写，故填Those。 8. tell 解析：can是情态动词，后接动词原形，“告诉”译为tell，故填tell。 9. Why 解析：“为什么”译为Why，用于引导特殊疑问句，句首首字母大写，故填Why。 10. shops 解析：shop是可数名词，a lot of后接复数形式，shop的复数为shops，故填shops。 五、按要求完成句子 1. What; doing 解析：画线部分“drawing pictures”表示正在做的事情，用疑问词What提问，现在进行时的疑问句结构为“What are sb. doing?”，故答案为What; doing。 2. are not 解析：现在进行时的否定句结构为“主语+be+not+动词-ing”，原句be动词为are，故填are not。 3. What is; doing 解析：画线部分“cooking”表示正在做的事情，用疑问词What提问，主语your mum是第三人称单数，be动词用is，后接doing，故答案为What is; doing。 4. Are; cleaning 解析：现在进行时的一般疑问句结构为“Be+主语+动词-ing?”，主语they是复数，be动词用Are，后接cleaning，故答案为Are; cleaning。 5. He is singing 解析：主语They改为He（第三人称单数），be动词由are改为is，sing的-ing形式不变，故答案为He is singing。 六、选择正确的选项补全对话 1. B 2. C 3. E 4. F 5. A 解析： - 第1空：根据答句“I'm good.”，可知问句是反问对方“你呢？”，选项B（And you?）符合语境，故选B。 - 第2空：根据答句“My parents are office workers.”，可知问句询问对方父母的情况，选项C（What about your parents?）符合，故选C。 - 第3空：根据答句“I can cook for her and we take a walk in the park.”，可知问句询问“你能为妹妹做什么？”，选项E（What can you do for your sister?）符合，故选E。 - 第4空：根据问句“What's in your community?”和答句“I often play basketball there.”，可知社区里有操场（playground），选项D（医院）与打篮球无关，故选F。 - 第5空：问句是“Do you like sports?”，肯定回答为“Yes, I do.”，选项A符合，故选A。 七、阅读理解 A) 阅读选择 1.
