强调句与虚拟语气

强调句与虚拟语气两种句型的各种格式和要点举例说明

解题思路： 如下
解题过程：
强调句型用法：
一,强调句型的构成
It + be (is / was) +被强调部分+ that(强调部分是人时也可用who或whom)+其他部分.
在英语中，我们常用It is／was… who/that结构来突出强调句子的某一成分(一般是句子中主语，宾语或状语)。在这个句型中，it没有词汇意义，只是引出被强调的成分。如果被强调的成分是表示人的词，用who或that来连接都可以。如果是其它成分，则一律用that来连接。 如：
It is my mother who／that cooks every day.
It was yesterday that Tom passed in the maths exam．
It + be (is / was) +被强调部分+ that(强调部分是人时也可用who或whom)+其他部分.
二,强调句型的判断
把"It, be that"去掉,如果剩余部分句子结构仍然完整(被强调部分要还原到原位置),那么这个句子就是强调句;如果句子不完整,则不是强调句.
(1)It was at theatre __________ Lincoln was murdered.
where B. at which
C. which D. that
(2)It was the theatre _________ Lincoln was murdered.
which B. that
C. where D. the one
分别把两句中的"It was"和所填部分去掉,得到以下两句:
1. At the theatre Lincoln was murdered. (Lincoln was murdered at the theatre.)
2.The theatre Lincoln was murdered.
句(1)仍是一个完整的句子,是强调句;句(2)句子不完整,不是强调句,而是含有定语从句的复合句.答案分别为D,C.
三,强调句型7注意：
1. 句首词用"It",不能用"This","That"等.
2. be动词总用单数形式,即is或was,不能用复数形式are或were.
3. 被强调的部分如果是代词,强调主语用主格,强调宾语用宾格.如:
(3)It is him that (who/ whom) I met in the street yesterday.
(4)It is I who am wrong.
4. 连接词一般用that,当强调部分是人时,强调主语也可用who,强调宾语也可用whom或who.
特别注意当强调部分是时间状语或地点状语时,不能用when或where.
如:5)It was on Oct. 1st, 1949 that People's Republic of China was founded.
5. 其他部分中的主谓一致问题.
若强调部分是句子的主语,强调部分是单数,谓语动词用单数形式;若强调部分是复数,则谓语动词用复数形式.如:
(6)It is Mary who often helps me with my English.
(7)It is I that am against you.
6. 疑问句的强调结构:
一般疑问句:Is / Was + it + that +句子的其他部分(陈述语序).
特殊疑问句:特殊疑问词+ is / was + it + that +句子的其他部分(陈述语序).如:
(8)Was it in 1985 that he graduated from middle school .
(9)When was it that you heard from him last time .
7. 强调句不能强调句子的谓语部分.
强调谓语动词时在动词原形前加助动词
do, does, did 如:
I do like the book.
