冀教英语七上Unit5语法讲解及习题:
现在进行时(二)(疑问句专项)
一、核心语法精讲:现在进行时疑问句专项
(一)知识点衔接回顾
现在进行时核心结构:主语 + am/is/are + 动词-ing,表此时此刻或现阶段正在进行的动作。句式变换全程依托be动词变形,无需助动词do/does,这是区别于一般现在时的核心关键。
(二)现在进行时一般疑问句(必考)
1. 句式结构
Am/Is/Are + 主语 + 动词-ing形式 + 其他?
变形规则:直接将句中的be动词(am/is/are)提前至句首,句末句号改为问号,其余成分语序不变。
2. 人称be动词匹配规则
· 主语为第一人称单数 I → 句首用 Am
· 主语为第三人称单数(he/she/it/单数人名/单数物品/单数动物)→ 句首用 Is
· 主语为you/we/they/复数名词/复数动物 → 句首用 Are
3. 标准问答方式
肯定回答:Yes, 主语 + am/is/are.
否定回答:No, 主语 + am not/isn’t/aren’t.
⚠️ 核心禁忌:回答必须前后be动词一致,绝对不能用do/does作答。
4. 例句示范
· I am reading books.(肯定句)→ Am I reading books?(一般疑问句)
· She is feeding the dog. → Is she feeding the dog? Yes, she is. / No, she isn’t.
· They are playing football. → Are they playing football? Yes, they are. / No, they aren’t.
(三)现在进行时特殊疑问句(重难点)
1. 句式结构
特殊疑问词 + Am/Is/Are + 主语 + 动词-ing形式 + 其他?
变形逻辑:先按照一般疑问句变语序(be动词提前),再在句首加上对应疑问词,全程保持倒装语序。
2. 高频疑问词
疑问词
提问内容
例句
What
对正在做的动作提问(最常用)
— What are you doing? — I am drawing pictures.
Who
对动作执行者(人/物)提问
— Who is singing? — My sister is.
Where
对动作发生的地点提问
— Where are they running? — They are running on the playground.
3. 核心考点补充
Who 作主语时,默认视为第三人称单数,搭配be动词 is,是单选、句型转换高频考点。
(四)高频易错点汇总
· 1. 现在进行时疑问句不用do/does,只用be动词提前,杜绝混用一般现在时句式;
· 2. am not 无缩写形式,否定回答应该写成 I’m not;
· 3. 特殊疑问句必须倒装,疑问词后紧跟be动词,语序不能还原成陈述句;
· 4. 问答一致原则:用Is提问必用is回答,用Are提问必用are回答。
(五)单元专属记忆口诀
进行疑问很简单,be词提前问号换;
特殊疑问加词前,语序倒装不能变;
问答匹配要牢记,不用do来不用does。
