内容正文:
七年级英语上册Unit 2 Hobbies
语法专项精讲与分层精练
本单元核心语法为实义动词的一般现在时、爱好类固定动词搭配、频度副词用法,是七年级上册期中、期末必考重点,也是小学到初中时态学习的分水岭。
一、核心语法一:实义动词一般现在时(本单元重中之重)
(一)语法定义
一般现在时用于描述经常性、习惯性的动作、个人爱好特长、客观事实。主要用于表达日常爱好、日常活动,贴合单元主题Hobbies。
(二)核心句式结构
1. 肯定句
主语为I/You/We/They、复数名词:主语 + 动词原形 + 其他
例句:I love reading. 我喜欢阅读。
例句:They play basketball after school. 他们放学后打篮球。
主语为He/She/It、单数名词、不可数名词(第三人称单数,简称三单):主语 + 动词三单形式 + 其他
例句:He enjoys swimming. 他喜欢游泳。
例句:My sister watches TV every evening. 我妹妹每天晚上看电视。
2. 否定句
非三单主语:主语 + don’t + 动词原形 + 其他
例句:We don’t like running. 我们不喜欢跑步。
三单主语:主语 + doesn’t + 动词原形 + 其他
易错核心:否定句中,三单动词必须还原为原形,绝对不能加s/es
错误示例:He doesn’t likes singing.(×)
正确示例:He doesn’t like singing.(√)
3. 一般疑问句(Yes/No提问)
非三单主语:Do + 主语 + 动词原形 + 其他?
回答:Yes, 主语 + do. / No, 主语 + don’t.
三单主语:Does + 主语 + 动词原形 + 其他?
回答:Yes, 主语 + does. / No, 主语 + doesn’t.
核心考点:疑问句中所有主语后的动词一律用原形
4. 特殊疑问句
结构:特殊疑问词(What/Who/How often) + 一般疑问句语序
例句:What does she like doing? 她喜欢做什么?
(三)动词三单变化规则(必考默写)
1. 一般动词:直接加s 例:read-reads, play-plays
2. 以s/x/ch/sh/o结尾:加es 例:watch-watches, go-goes
3. 辅音字母+y结尾:变y为i加es 例:study-studies
4. 特殊不规则变化:have-has(本单元最高频考点)
(四)高频易错点总结
1. be动词和实义动词不能混用,句子有实义动词就不用am/is/are
错误:He is like drawing.(×) 正确:He likes drawing.(√)
2. every day、usually、often、never是一般现在时标志性时间状语
二、核心语法二:爱好类动词固定搭配(单元专属考点)
本单元所有表达爱好的动词,后接动词ing形式,为固定搭配,无例外,是选择题、填空题、改错题高频考点。
(一)必背固定搭配
1. like doing sth 喜欢做某事
2. love doing sth 热爱做某事
3. enjoy doing sth 享受/喜欢做某事
4. be good at doing sth 擅长做某事
5. be interested in doing sth 对做某事感兴趣
(二)重点解析
1. 以上短语后只能接动名词doing,不能接to do或动词原形
2. 主语为三单时,仅前面动词变三单,后面doing形式不变
例句:She enjoys listening to music.(enjoy变三单,listen用listening)
3. 同义句转换考点(单元高频句型)
I like playing football. = Playing football is my hobby.
三、核心语法三:频度副词用法
(一)常用频度副词(按频率从高到低)
always(总是)> usually(通常)> often(经常)> sometimes(有时)> seldom(很少)> never(从不)
(二)唯一固定位置(必考语序)
1. 实义动词之前
例句:I often read books. 我经常看书。
例句:He never plays computer games. 他从不玩电脑游戏。
2. be动词、情态动词之后
例句:She is always happy. 她总是很开心。
(三)配套疑问句式
用How often对频度副词、频率短语提问
例句:—How often do you swim? 你多久游泳一次?
—I seldom swim. 我很少游泳。

四、语法专项基础精练
(一)动词适当形式填空
1. like 解析:主语I为第一人称,一般现在时动词用原形。
2. enjoys 解析:主语my brother为三单,动词变三单,直接加s。
3. don’t love 解析:主语they为复数,否定句用don’t+动词原形。
4. watch 解析:does引导疑问句,后面动词必须还原原形。
5. doesn’t like 解析:主语the cat为三单,否定用doesn’t+动词原形。
6. drawing 解析:固定搭配be good at doing sth,at为介词,后接doing。
7. studies 解析:主语he为三单,辅音+y结尾,变y为i加es。
8. has 解析:主语Linda为三单,have不规则变三单为has。
9. swimming 解析:固定搭配be interested in doing sth。
10. play 解析:主语my parents为复数,never不改变动词形式,用原形。
(二)单项选择
1. B 解析:主语Tom三单,谓语动词用三单形式likes,排除A、C;be like意为“像”,不符合句意。
2. A 解析:主语you为第二人称,疑问句用Do引导,回答对应do。
3. C 解析:doesn’t后接动词原形;主语she三单,后半句动词用三单likes。
4. C 解析:be good at后固定接动名词形式。
5. B 解析:根据后半句“工作日忙于学习”,可知很少踢足球,seldom表示“很少”。
6. D 解析:根据“没有空闲时间”,可知从不锻炼,never表示“从不”。
7. B 解析:everyone作主语,视为三单,谓语动词用has。
8. B 解析:句中有实义动词watch,否定用don’t,主语we为复数。
(三)句型转换
1. don’t like 解析:主语I,实义动词否定用don’t+原形。
2. Does; enjoy; does 解析:主语he三单,疑问句用Does引导,动词还原,肯定回答用does。
3. How often 解析:对频度副词提问,固定用How often。
4. has 解析:主语改为三单he,have变has。
5. does well in 解析:be good at 同义短语为do well in,主语she三单,do变does。
五、语法专项提升精练
(一)改错题
1. don’t 改为 doesn’t 解析:主语he三单,否定助动词用doesn’t。
2. to listen 改为 listening 解析:enjoy后只能接doing形式。
3. likes 改为 like 解析:does提问,动词还原原形。
4. 去掉am 解析:句中有实义动词play,无需be动词。
5. always is 改为 is always 解析:频度副词置于be动词之后。
(二)完形填空
1. love 2. read 3. has 4. likes 5. seldom
2. is not / isn’t 7. enjoys 8. plays
单元语法总结(必背口诀)
1. 一般现在时:三单动词要变形,疑问否定助动词;does出现现原形,don’t doesn’t分人称。
2. 爱好动词很固定,like/enjoy/good at,后面全部加ing。
3. 频度副词有顺序,实前be后要记清,how often问频率。
