9. 强调句型 It is(was)+被强调部分+that/who+句子其他部分
[课本原句]It was John’s quick action and knowledge of first aid that saved Ms. Slade’s life.正是约翰的快速反应和急救知识拯救了斯莱德女士的生命。 [用法解析]
(1)在强调句型中，将被强调的部分放在前面，其它部分置于that之后，被强调部分可以是主语，宾语，表语或状语，强调的主语如果是人，that可以由who换用。如果把这种句型结构（it is/was…that/who）划掉后，应该是一个完整无缺的句子；这也是判断强调句型与其它从句的方法。 (2)几种强调句型变式：
一般疑问式：Is/ Was it +被强调部分+ that…？ 特殊疑问式：特殊疑问词+is/was it that…？
反义疑问式：It is/was+被强调部分+that…，isn’t / wasn’t it？
not ... until ... 的强调句型：It is/was not until + 被强调部分 + that... [用法检测]

If you think that shopping online on weekends can get you the best deals, then think again. According to a survey of online shopping, Tuesday is actually the best day of a week if you want to grab a bargain.
The best day of a week is Tuesday when savings are 4.81 percent, followed by Thursday at 4.80 percent. In the third place is Friday at 4.65 percent, then Monday at 4.30 percent and Wednesday at 4.13 percent. It’s not advisable to shop on Saturday when you only save 3.84 percent and Sunday is the worst with 3.37 percent.
Shopping online has become something of a science. So, if you do not want to spend more than you should, do it on the right day.
