感叹句的用法 高频易错点01
1.语法概念:一般现在时在本单元专门用于表示周末习惯性、经常性的活动,强调 “反复发生
的动作”,是单元最基础且必考的语法点。
2.单元标志词(必须熟记,判断时态的关键):often(经常)、usually(通常)、sometimes(有时
)、every(every Saturday/weekend 每周六 / 周末)、on the weekend(在周末)、on Saturdays/
Sundays(在周六 / 周日)。
3.句型结构(单元专属,分主语类型)
主语类型
肯定句结构
单元例句
第一 / 二人称(I/you/we/they)+ 复数主语
主语 + 动词原形 + 周末活动 + 时间标志
I watch TV on the weekend.(我周末看电视。)They do homework on Saturdays.(他们周六做作业。)
第三人称单数(he/she/it/ 单个人名,如 Tom/Lily)
主语 + 动词三单形式 + 周末活动 + 时间标志
She reads a book on Sundays.(她周日看书。)Tom plays football every weekend.(汤姆每周踢足球。)
4.单元动词三单变化规则(高频考点)
一般情况直接加 - s:watch→watches、play→plays、read→reads、clean→cleans(单元核心动词);
以 s/x/ch/sh/o 结尾加 - es:do→does、go→goes(单元高频动词);
单元无特殊变形动词,重点掌握以上两类。
易错点提示
1.三单主语后用动词原形(×):He watch TV on Sundays. → 正确(√):He watches TV on
Sundays.(主语 he 是三单,动词用 watches);
2.复数主语后用三单动词(×):They plays football on the weekend. → 正确(√):They play
football on the weekend.(主语 they 是复数,动词用原形);
3.遗漏时间标志词导致时态判断错误(×):She reads a book. → 补充单元标志词(√):She reads
a book on Saturdays.(明确是周末习惯性活动)。
小练笔
单项选择
( ) 1. My sister ______ a book every weekend.
A. read B. reads C. reading
( ) 2. We ______ homework on Saturdays.
A. do B. does C. did
( ) 3. Tom often ______ swimming on Sundays.
A. go B. goes C. going
用括号内单词的正确形式填空
1. I usually ______ (clean) the room on the weekend.
2. She ______ (not play) the piano on Saturdays.(否定句)
3. My father ______ (watch) TV every Sunday evening.
点拨
1. B 主语 my sister 是第三人称单数,every weekend 是单元时间标志词,动词 read 用三单形式 reads,符合一般现在时三单规则。
2. A 主语 we 是复数,on Saturdays 是单元时间标志词,动词用原形 do,匹配复数主语的语法规则。
3. B 主语 Tom 是三单,often 是单元频度副词,动词 go 的三单形式是 goes,遵循 “以 o 结尾加 - es” 的规则。
用括号内单词的正确形式填空
1. clean 主语 I 是第一人称,usually 是单元标志词,动词用原形 clean,符合一般现在时原形规则。
2. doesn't play 主语 she 是三单,否定句需用助动词 doesn't,后接动词原形 play;on Saturdays 是单元时间标志,明确时态为一般现在时。
3. watches 主语 my father 是三单,every Sunday evening 是单元时间标志,动词 watch 以 ch 结尾,三单加 - es,变 watches。
助动词 do/does 的用法(单元疑问句 & 否定句核心) 高频易错点02
1.语法功能:助动词 do/does 在本单元用于构建一般现在时的否定句和疑问句,无实际含义,
仅辅助实义动词(单元周末活动动词)完成句式变形。
2.do/does 的选择规则(单元专属)
用 do:主语为 I/you/we/they(复数)或复数名词(如 the children),搭配单元动词原形;
用 does:主语为 he/she/it/ 单个人名(如 Lily),搭配单元动词原形(注意:does 后实义动词
必须还原为原形)。
3.单元核心句式变形(必考,分否定 / 疑问)
句式类型
结构(do/does)
单元例句(肯定→否定→疑问)
否定句
主语 + don't/doesn't + 动词原形 + 活动 + 时间
肯定:I play football on the weekend.否定:I don't play football on the weekend.肯定:She reads a book on Sundays.否定:She doesn't read a book on Sundays.
一般疑问句
Do/Does + 主语 + 动词原形 + 活动 + 时间?
复数主语:Do you do homework on Saturdays?(你周六做作业吗?)三单主语:Does he go swimming on the weekend?(他周末去游泳吗?)
特殊疑问句
特殊疑问词(What/When)+ Do/Does + 主语 + 动词原形 + 时间?
What do you do on the weekend?(你周末做什么?)What does she do on Sundays?(她周日做什么?)
4.答句规则(单元固定应答)
一般疑问句答句:Yes, 主语 + do/does./ No, 主语 + don't/doesn't.(例:—Do you watch TV?
—Yes, I do. / —Does she read a book? —No, she doesn't.);
特殊疑问句答句:直接回应疑问内容,无需 Yes/No(例:—What do you do on the weekend?
—I draw a picture.)。
易错点提示
1. 三单疑问句用 do(×):Do he play football? → 正确(√):Does he play football?
(主语 he 是三单,用 does 引导);
2. does 后用三单动词(×):Does she reads a book? → 正确(√):Does she read a book?
(does 后动词必须还原为原形);
3. 否定句直接加 not(×):She not play the piano. → 正确(√):She doesn't play the piano.
(需借助助动词 doesn't,不能直接加 not)。

3. B 主语 your brother 是第三人称单数,特殊疑问句用 does 引导,what 提问周末活动,贴合单元核心句型。
句型转换
1. I don't watch TV on the weekend.
解析:主语 I 是第一人称,否定句用 don't + 动词原形 watch,其余成分(TV/on the weekend)不变,符合单元否定句语法规则。
2. —Does she read a book on Sundays? —No, she doesn't.
解析:主语 she 是三单,一般疑问句用 does 引导,动词 read 还原为原形;否定答句用 “No, she doesn't.”,遵循单元固定应答规则。

解析:对单元活动 “clean the room” 提问用 what,主语 they 是复数,用 do 引导特殊疑问句,动词 do 保持原形,符合单元特殊疑问句结构。
时间介词 in/on/at 的精准搭配高频易错点03
1. 语法功能:介词 in/on/at 在本单元用于明确周末活动的时间,三者搭配不同时间类型,无替
