强调句型
强调句型
通过改变句子正常语序来突出强调句中某一特定部分(如主语、宾语、状语等)。
概念
1. 基本结构
2. 一般疑问句
3. 特殊疑问句 被强调部分是疑问词。
4.否定句
结构
01
强调句型
It is / was +被强调部分+that / who+...
Is / was it+被强调部分+that / who+...
特殊疑问词(被强调部分)+is / was +that / who+...
It is / was not +被强调部分+that / who...
1. It is/was:固定的开头,时态由原句的时态决定。
2. 被强调部分:这被强调部分放在这里
3. that/who:连接词。若被强调的部分是人,用 who 或 that;若被强调的是物,则只能用 that。
4. 句子其余部分:原句剩下的部分,通常按原句语序排列。
四部分结构
02
强调句型
主语、宾语或状语等
原句:Alice bought a book in the store yesterday.
1.强调主语
2.强调宾语
3.强调地点状语

强调句型
It was Alice who / that bought a book in the store yesterday.
It was a book that Alice bought in the store yesterday.
It was in the store that Alice bought a book yesterday.
It was yesterday that Alice bought a book in the store.
特点
03
强调句型
将 It is/was...that/who... 框架去掉后,剩下的部分必须能组合成一个完整的、意思正确的句子。
如: It was Alice who / that bought a book in the store yesterday.
检验强调主语的句子:去掉框架后是 Alice bought a book in the store yesterday.这是一个完整的原句,证明强调句正确。
与not until相结合
04
强调句型
结构: It is/was+not until...(被强调部分)+...that/who...
如:
原句:He didn’t come back until after midnight.
与强调句相结合:
It was not until after midnight that he came back.
05
there be句型
“There + be动词 + n.(存在主体) + 方位/时间状语”的倒装形式
结构

there be句型

注意
be动词的单复数需与后续主语严格一致

主语
存在多种时态变形,包括
一般现在时(There is/are)
一般过去时(There was/were)
一般将来时(There will be)
完成时(There has/have /had been)
时态变化规则

there be句型
由there引起的句式,若主语不止一个时,谓语动词的数通常和最邻近的主语保持一致
There ____ (be) three books and a pen on the desk.
There _____ (be) a pen and three books on the desk.
主谓一致
