人教英语七上Unit6语法讲解及习题:疑问词(what/what time/when)与一般现在时
第一部分 语法精讲
语法一:三大疑问词辨析(what / what time / when)
本单元核心考点,三组疑问词均用于引导特殊疑问句,针对日常作息、时间、活动提问,核心区别在于提问范围和精度不同,是单选、句型转换、对划线提问高频考点。
1. What time(精准时间提问)
核心用法:仅用于提问具体的钟点时刻(几点几分),答案必须是带at的具体时间,不可回答日期、时段、活动。
固定句型:What time + do/does + 主语 + 动词原形?
例句:—What time do you go to school? —I go to school at 7:20.
2. When(宽泛时间提问)
核心用法:提问所有时间类型,涵盖具体钟点、星期、日期、早中晚、时段(周末、饭后)等,范围最广。
特点:可以完全替代 What time 使用,但 What time 不能替代 when。
例句:—When do you play sports? —I play sports on Sunday./At 5:00 p.m.
3. What(行为动作提问)
核心用法:不提问时间,专门提问具体做的动作、活动、事情,用于回答具体行为。
固定句型:What + do/does + 主语 + do(+ 时间状语)?
例句:—What do you do in the evening? —I do my homework and read books.
4. 三大疑问词终极区分口诀
问几点几分用what time,问所有时间when通用;
问做什么事只用what,三者用法不互通。
语法二:作息场景一般现在时(高频三单变形)
本单元专门用一般现在时描述日常、习惯性作息行为,常搭配频率副词:usually、often、sometimes、every day/weekend。
1. 主谓一致规则
· 第一二人称/复数主语(I/you/we/they):谓语动词用原形
· 第三人称单数主语(he/she/it/单人名/单数物):谓语动词变三单形式
2. 作息动词三单变形核心规则
· 普通动词直接加s:get→gets, play→plays
· s/x/ch/sh/o结尾加es:watch→watches, go→goes, do→does
· 辅音+y结尾变y为i加es:study→studies
3. 基础句型结构
肯定句:主语 + 动词原形/三单 + 时间状语
否定句:主语 + don’t/doesn’t + 动词原形
疑问句:Do/Does + 主语 + 动词原形?
三、高频易错点汇总
1. What time 只能答钟点,不能答on Monday、after school等宽泛时间;
2. when 提问可答任意时间,是考试万能时间疑问词;
3. 三单主语疑问句/否定句中,动词必须还原原形(Does he go... ✔ / Does he goes... ❌);
4. What引导作息问句,必须搭配实义动词do,不能遗漏。
