三、用句子来强调

A．句型强调

英语中最常见的强调手段，也是我们必须要掌握的方法就是句型强调，即：强调句型。It is / was + 被强调的部分 + that (who)…如：

(1) It was in the room that Li Lei was born. 李蕾出生就在这间房子。

(2) It is Wei Fang who has broken the record. 就是魏方打破了纪录。

B．在使用强调句型时须注意的几个问题：

(A) 原句子是现在时或将来时，强调句用It is + 被强调的部分 + that (who)…; 若原句子是过去时，强调句用：It was + 被强调的部分 + that (who)…

(1) Li Lei’s father will work in America. —It is in America that Li Lei’s father will work. 李蕾的父亲的工作将就在美国。

(2) I studied at this school a few years ago. —It was at this school that I studied a few years ago. 几年前我就在这所学校读书。

(B) 即使被强调的部分是复数，It后面始终用单数形式。如(from www.yygrammar.com)

(1) Tom and Lucy gave us much help. —It was Tom and Lucy that gave us much help. 正是汤姆和露西给了我们很多的帮助。

(2) I saw swans in the lake yesterday. —It was swans that I saw in the lake yesterday. 昨天我看到在湖里的就是天鹅。

(C) 强调人时，可用who 代替that, 但若强调时间、地点、原因、方式时，不能用when, where, why, how代替 that。如：

(1) It is our teacher who / that helps us make great progress. 正是我们的老师帮助我们取得了很大的进步。

(2) It is by bus that I go to school every day. 每天我就是乘公共汽车上学。

(D) 在强调not…until结构中的时间状语时，应将not移到until前，再将not until部分移到被强调的位置。如：

I didn’t go to bed until twelve o’clock last night. — It was not until twelve o’clock last night that I went to bed. 昨天晚上我一直到十二点才睡。
