英语中常见的用来表示强调的句型有以下几种。
1.It is / was + 被强调部分 + that/who + 其他成分
I met him in the park this morning.
→It was I who / that met him in the park this morning.（强调主语）
→It was him that I met in the park this morning.（强调宾语）
It was in the park that I met him this morning.(强调地点状语)
It was this morning that I met him in the park.(强调时间状语)
【注意 】
①如果原句中谓语动词使用的是现在范畴的时态(一般现在时/现在进行时/现在完成/现在完成进行时/一般将来时/将来进行时/将来完成时等)用It is...that/who...。如果原句中谓语动词为过去范畴的时态(一般过去时/过去进行时/过去完成时/过去将来时等)则用It was...that/who...。
It was Peter who / that got the first place in the final exam.
It is not everyone who / that can pass the college entrance exam.
②强调句型的一般疑问句只需把is / was提前，它的特殊疑问句只需在一般疑问句前加上疑问词。如:
Was it Smith who / that broke the window?
Who was it that broke the window?
③not...until...的强调句式
当被强调的是not...until...句型时，应将not置于until之前，主句由否定句改为肯定句。如:
We didn’t recognize her until she took off her glasses.
→It was not until she took off her glasses that we recognized her.
（注：Not until she took off her glasses did we recognize her. 此句为否定词not位于句首， 句子要用部分倒装）
2.谓语动词的强调
It is / was...that/who...结构不能强调谓语，如果需要强调谓语时，则用助动词do / does / did + 动词原形表示。 如:
He did tell all that had happened to him.
She does get up early every day.
Mary， do come to my birthday party tonight.
3.用形容词very， only， single， such等来修饰名词来表示强调
This is the very book that I’m looking for.
He is the only one of the students who passed the English test.
Not a single spelling mistake did he make in the composition.
4. 用倒装句来强调以加强语气
Never shall I forget the day when Mr. Wang gave us the first lesson.
So aloud did he speak that everyone could hear him clearly.
