強(qiáng)調(diào)句：英語的強(qiáng)調(diào)主要有兩種：一是強(qiáng)調(diào)非謂語(包括主語、賓語、狀語等)；二是強(qiáng)調(diào)謂語動詞。

(一)強(qiáng)調(diào)非謂語

其基本句型是：“It + is/was + 被強(qiáng)調(diào)的成分 + that/who + 其她成分”。It 沒有實(shí)意，只起語法作用，引導(dǎo)被強(qiáng)調(diào)的部分。當(dāng)被強(qiáng)調(diào)的是人時，可用who(m)/that, 其他情況用that。

例如：

It was I who/that met Jack yesterday. 是我昨天碰到了Jack.(強(qiáng)調(diào)主語)

It was Jack that/whom I met yesterday. 我昨天碰到的是Jack。(強(qiáng)調(diào)賓語)

It was yesterday that I met Jack. 是昨天我碰到了Jack.(強(qiáng)調(diào)時間狀語)

這幾句話復(fù)原為非強(qiáng)調(diào)句就是：I met Jack yesterday.

It is people, not things, that are decisive. 決定的因素是人，不是物。(強(qiáng)調(diào)主語)
