it习题巩固强调句型难点

“it”的用法（2）

一、强调句型基本用法。

1. yesterday, iin the park.昨天，我在公园丢失了手表。

⑴itlost my watch in the park yesterday. (昨天在公园丢失了手表的是我)

iti lost in the park yesterday. (昨天在公园丢失了的是我的手表)

itthat i lost my watch yesterday. (昨天在公园我丢失了手表。)

注意1〗这种强调句型能强调除___之外的句子成分，强调谓语可以在动词原形前面加do/does/did ,如：they __go to see you yesterday.2.

it is his friends who/that are planning to go to beijing.3. it is i that/who __be) to blame..

注意2〗无论强调的是人还是物，是单数还是复数，be动词一律用单数形式___或___

强调主语时，that/who之后的谓语动词在人称和数上应与句子主语一致。强调的主语是人时，常用that或者___强调的宾语是人时，多用that或___4. the last emperor died in this palace.

in this palace that the last emperor died?(这就是最后一个皇帝死去的宫殿吗？)

that died in this palace? (谁死在这宫殿呢？)

that the last emperor died? (最后一个皇帝死在**？)〖注意3〗强调句的各种句式结构。

陈述句式：it is/was+被强调部分+that/who+其他部分。

一般疑问句式：is/was +it+被强调部分+that/who+其他部分？特殊疑问句式：特殊疑问词+is/was +it+被强调部分+其他部分？

5.⑴he didn’t go to bed until ten o’clock.

not until ten o’clockto bed.

not until ten o’clock that he __to bed.

i didn’t realize she was a famous film star until she too off her dark glasses.

itwasshetookoffherdarkglasses___i___shewasafamous film star.

注意4〗当被强调的是not…until句型时，应将not与until部分一起强调，即构成it is/was not until …that…结构。由于not已经前移，that后应用肯定句式。

二、与几种易混句型的区别〖注意5〗判断是否是一个强调句，可以通过去掉的方法。去掉以后如果句子意思完整，就是强调句。1、判断下面两个句子是强调句还是主语从句1）it was a pity that you didn’t attend the party then .

2）it is true that he once went to canada.

2、判断下面两个句子是强调句还是状语从句。it was 1996 __we came was in 1996 __we came here.

3、判断下面两个句子是强调句还是定语从句a. it’s the house __he it’s in the house __he lives）it was last spring __they worked together___they began to become goodfriends.

2）it was in the school __they had their schooling __they had a get-togetheragain twenty years later.

注意6〗若强调句型中被强调部分含有定语从句，注意对定语从句引导词及强调句型中的that做出正确的判断。
