强调句的核心考点
1.使用助动词do，does和did对谓语动词进行强调。
First impressions really do count.
2.运用强调句型来强调除谓语动词以外的其他句子成分。
强调句型的基本句型结构为：It is/was+被强调部分+that/who+其他成分。可用来强调句子的主语、宾语、状语、表语、同位语等成分。在复习强调句型时，要注意以下几个方面：
(1)强调句型中的主谓一致
在强调句型中，当对陈述句中的主语进行强调时，无论被强调的主语是单数还是复数，主句中的谓语动词都要用单数形式It is/was...，同时，that从句中的谓语动词要与被强调的主语在人称和数方面保持一致。
It is my parents that/who often help me get out of trouble.
(2)当对地点状语、时间状语或其他状语从句进行强调时，只能用连接词that，而不能用where，when，why或how等。
It was on August 8,2008 that the 29th Summer Olympic Games were opened in Beijing.
(3)强调句型的疑问句
在强调句中，无论被强调部分是什么句子成分，变为一般疑问句时，都须将主句改为疑问语序，即将“It is/was+被强调部分+that+其他成分”改为“Is/Was it+被强调部分+that+其他成分?”或“疑问词+is/was it that+其他成分?”结构。
Was it her failing her exam that made her parents unhappy?
When was it that she changed her mind?
(4)在对not...until...结构中的until时间状语或时间状语从句进行强调时，要将句中的not移至until之前，构成：It is/was not until...that...。注意that从句中的谓语动词要变成肯定形式，而且不再采用倒装语序。
I didn’t realize she was a famous film star until she took off her dark glasses.=It was not until she took off her dark glasses that I realized she was a famous film star.
注意事项：
1.如果由特殊疑问词引导的强调结构在句中作宾语从句时，从句必须使用陈述语序，不可用疑问语序。
He asked me who it was that took his umbrella by mistake.
2.强调句型结构中的反意疑问句式。
在强调句型结构中，其反意疑问句的主语及助动词必须与主句It is/was...保持一致。
It is Mary not you who wants to ask me about that matter，isn’t it?
3.强调句型结构与定语从句的混合使用。
在高考试题中，为了增加试题的难度，命题人常将强调句型与定语从句混合起来，使句子结构更加复杂。我们要注意从语法角度来分析句子，理清结构“强调句型与定语从句”。
It was on the farm where we worked that I got to know her.
4.强调句型与时间状语从句的辨析。
当用强调句型强调时间状语时，去掉“it is/was”和连词“that”，原句仍然完整;而在时间状语从句中，若去掉“it is/was”和连词“when/before”，原句不完整。
It was at 14：28 that the terrible earthquake broke out.(强调句型)
It was 14：28 when the terrible earthquake broke out.(状语从句)
