强调英语句型

强调句型：It is/was +… who/that…；被强调部分如果为主格人称代词，who/that后的动词和主格人称代词在人称和数上保持一致。

1. 如强调句型指现在或未来的情况用It is指过去用It was。

e.g. It is I who/ that am wrong.

分析：被强调部分为人强调词可用who也可用that. 指现在的情况所以以 It is开头，被强调部分是 I谓语用 “am”

原句： I am wrong.

e.g. It was him who\that I saw the day before yesterday.

原句为 I saw him the day before yesterday.

分析：指过去的情况用It was 开头，被强调部分为人所以强调词仍是who\that.

2. 被强调部分往往为句子的主语、宾语、时间状语、地点状语等，但有时也可以强调比较复杂的内容。 如时间状语从句、地点状语从句、not until… 结构、not only…but also…和as well as…等结构。

e.g. It was only when I reread his poems recently that I began to appreciate their beauty. (appreciate means understand and enjoy the good qualities or value of something欣赏、鉴赏、领会)

分析：强调部分为复杂的时间状语从句强调词不能使用when只可用that

e.g.It is not only he but also his parents who\that have been to Beijing.

3. 被强调部分为人称代词时，原句用什么格强调句也用什么格。

It强调句型最基本的句式结构为：

It be＋被强调部分＋that/who＋句子。被强调部分是除谓语之外的其他句子成分，可以是单词、短语，也可以是从句；当强调人时，可以用who 或that；强调其他成分，则只能用that。对not……until……结构的强调句型为：It is/ was not until+被强调部分+that+其他部分。
