英语中为了加强语气，增加对比效果与感情色情，常常使用强调语气。常见表现形式如下：
一、用It is/was被强调部分+that+原句其余部分句型强调，这是历届高考常考常新 的一个知识点。使用该句型要注意几点
(一)原句谓语动词是现在时态，用is，是过去时态则用was。
(二)该句型可以强调句中除谓语动词以外任何句子成分。
(三)that后面的原句其余部分只除去了被强调部分，且词序及词形都不可以改动。
(四)当被强调部分是表人的名词时，that也可以用who(m)替代，其他情况一律只可以用that 。例如：
原句：Tom brought some money with him to buy a new bike last night.
①It was Tom that/who brought some money with him to buy a new bi ke last night.(强调主语)
②It was some money that Tom brought with him to buy a new bike last night.(强调 宾语)
③It was to buy a new bike that Tom brought some money last night.(强调目的)
④It was last night that Tom brought some money to buy a new bike.(强调时间).
只有①强调的是人，that才可以代之以who，千万不要以此类推。例如④强调的是表示时间 的名词不用when取代that.此外，还有两点必特别留意。
(五)以疑问句形式出现该句型常常具有更大的隐蔽性。例如：
⑤Is it my letter that you're reading now?
⑥Where was it that Tom saw his friend last night?
(六)该句型还可以强调状语从句，注意强调以until引导的时间状语从句时，原句的not…un til 变成not until，即It was/is not until that…如：
⑦It was not until he came back that I went to bed.
⑧It was not until you came in that he stopped making a face.
(七)该句型易和It is/was+名词+that名词从句这一句型混淆。但后者的It is/was…that 是不 可去掉的，否则that前的名词就找不到位置，原句也不再成立，而任何强调句型的It is/wa s…that去掉后，句子仍然成立。例如①②。而下列主语复合句中的It was…that去掉后， 句子就不成立了。⑨It was the rule of the school t hat the pupils s hould wear their school uniforms.去掉It was … that 后，划线部分就无处挂靠了。
二、用助动词do或其变化形式does，did来强调句中谓语动词，用来加强陈述句和祈 使句的语气。译作“的确”，“一定”，“确实”。如：
①He does want to be a teacher.
②Alice did come here last week.
③Do come again.
三、同一个词反复使用是加强语气的常用手段之一，可以反复使用的一般是动词， 副词，形容词和名词。如：
①He worked (and) worked until late at night.(动词 )
②You must read the text over(and) over befor you can learn it by heart.(副词)
③I have been to Beijing many (and) many a time.( 形容词)
上述词的反复使用时，and可以省去。如：
④Tom nearly, nearly caught it yesterday.
⑤I'll never, never forget you.
名词反复使用以示强调时，前一个名词用单数形式，后一个名词用复数，中间介以of,以示 前者为后者之最。如：
⑥Agriculture is the foundation of foundations.
⑦Underson is confronted with a difficulty of difficultie s.
四、用on earth, the hell, the devil, in the world, at all等来加强疑问或否 定语气。如：
①Where the hell have you been to?
②The clerk is not at all fit for the post.
五、用夸张词来加强语气。如 a sea of trouble, a thousand and one car e, millions of reasons.
①Today's life is one thousand times better than that of those d ays.
②It is ages since I last saw you.
③The waves were mountain-high.
④That will do you a world of good.
⑤There are seas of red flags.
六、用反身代词来强调某人某物。如：
①I myself cleaned the blackboard this morning.
②The suggestion itself was very reasonable.
③We all passed the test.
④Tell them both to go away.
七、用同源宾语加强语气和句意。如：
①We are living a happy life.
②Last night I dreamed a pleasant dream.
③Liu Hu-nan died a hero's death.
④The baby laughed a sweet laugh.
八、在以though或as引导的状语从句中，把谓语部分提前表示强调，常带有赞许或 厌恶等情感色彩。如：
①Proud as these nobles are, they are afraid to see me.
②Cold though it was, they went on working hard.
如果从句中的表语是名词或名词短语，其前不带冠词。如：
③Child though he was, he could carry the heavy box.
④Monitor as he is, he always breaks the school rules.
事实上，英语就像汉语一样也常常用把一个本应在句中或句末的句子成份提前置于句首显著 位置的方法来表示强调。如：
⑤In front of the farmhouse there sat a little boy.
九、用what或wh-疑问词+ever构成的复合词引导名词性从句或状语从句来强调从句 中的主语，宾语或状语。如：
①What we need most is time.
②Whenever you go, you should listen to the Party.
③Whenever you come to me, you can come right in.
十、用形容词own, very, only, righ等，或副词very, never, ever, even, still , simply, just 等来表示强调。如：
①At that very monent he heard a cry for help.
②They are the only persons who escaped from the fire.
③Tom was my own brother.
④It is extremely hot in Summer in Guangdong.
