1、强调句用助动词do来强调当句子中没有其他的助动词时，我们可以在动词前使用助动词do表示对该动词的强调。如：Do be careful with that vase! 务必小心那个花瓶!I do hope youll stay for lunch. 我真的希望你留下吃午饭。用于表示强调的do可以有时态的变化，但其后的动词要用原形。如：He does look tired. 他确实显得很疲倦。He did come but soon went back. 他的确来过，但很快就回去了。She did write to say thank you. 她的确写信向你道谢了。注意，这样用的do只用于现在时
2、或过去式(即只有do, does, did这样的形式)，不能用于进行时、完成时等形式(如不用于is doing, has done等)。用某些形容词来强调英语中用于强调的形容词比较多，比如那些表示“极端”和“完全”概念的形容词通常就可以用于表示强调，这类形容词主要的有：mere 仅仅的 very 极端的outright 完全的 thorough 十足的plain 完全的 complete 彻底的pure 完全的 perfect 全然的Jim looked a perfect fool. 吉姆看起来像一个十足的傻瓜。At that very moment the phone rang. 正好在那
3、个时候电话铃响了。We gave the room a thorough cleaning. 我们把房间彻底打扫了一番。用某些副词来强调英语中有不少副词可以用于表示强调，比如only就是其中的一个。如：You may put the meeting off only when it is absolutely necessary. 你们可以把会议推迟，但只是在绝对必要时才能这样做。试比较：Only I kissed her last night. 昨晚只有我吻了她。I only kissed her last night. 昨晚只是吻了她。I kissed only her last nigh
4、t. 昨晚我吻的只有她。I kissed her only last night last night only. 我只是在昨晚才吻了她。用句首位置来强调在英语中，句首位置是通常用于表示强调的一个地方，当某个本来不应置于句首的成分放在句首，往往会对这个成分构成强调。比较：普通：He kept this job twenty years. 这个工作他做了20年。强调：This job he kept twenty years. 他做这个工作做了20年。普通：The students can understand this. 学生们是理解这一点的。强调：This the students can
5、understand. 这一点学生们是理解的。普通：I know that she is a good girl. 我知道她是一个好姑娘。强调：That she is a good girl I know. 她是一个好姑娘，我是知道的。普通：Press the red button to switch on. 请按红色按钮开机。强调：To switch on, press red button. 要开机，请按红色按钮。用定语从句来强调有时我们可以使用定语从句来对一个名词进行强调，如用the person who, the thing that, the place where, the day
6、 when, the reason why这样的结构，把需要强调的名词与定语从句连在一起。比较：普通：Mary keeps pigs in the garden shed. 玛丽在花园的棚子里养猪。强调：Mary is the person who keeps pigs in the garden shed. 玛丽就是在花园的棚子里养猪的那个人。(强调Mary)强调：The garden shed is the place where Mary keeps pigs. 花园里的棚子就是玛丽养猪的地方。(强调the garden shed)强调：The place where Mary keep
7、s pigs is the garden shed. 玛丽养猪的地方是花园里的棚子。(强调the place where Mary keeps pigs)用what从句来强调当what的意思是表示“所的”时，它通常具有强调意味，此时的what通常相当于“先行词+关系代词”结构。如：This is what I have to say. 这就是我所要说的话。句中的what相当于the thing that。What he says is not important. 他说的话并不重要。句中的what也相当于the thing that。He is no longer what he was. 他
8、已经不是以前的他了。句中的what相当于the person who。另外，what从句有时还可以用于强调动词。如：What we can do is (to) write to him. 我们唯一能做的事是给他写信。What you do is (to) mix the eggs with flour 你要做的事是把面粉和鸡蛋搅和在一起。用强调结构来强调英语中表示强调时有一个很重要的句型，那就是“it is (was)+被强调成分+that (who)+其他”结构。比较：It was in the office that he was killed. 他是办公室被杀害的。It is the
9、children who broke the window. 是孩子们打破窗户的。第一句的被强调的成分的是in the office，第二句的被强调成分是the children。其中that和who的区别是：当强调人时，可用that或who，当强调其他成分时，用that。注意，当强调时间和地点时，不能用when和 where 代替that。在具体使用时，要特别注意这类强调句的疑问句形式。比较：陈述句：It is because he is ill that he cant come. 是因为生病他才没有来。一般疑问句：Is it because he is ill that he cant
10、come? 是因为生病他才没有来吗?特殊疑问句：Why is it that he cant come? 他为什么不能来?另外，还要注意not.until这一句型的强调句莆式，它的基本形式是It is (was) not untilthat。如：直到我遇到你以后，我才真正体会到幸福。正常：I didnt know real happiness until I met you.强调：It was not until I met you that I knew real happiness.直到吃完饭他才现身。正常：He didnt turn up until the meal was over.
11、强调：It was not until the meal was over that he turned up.强调句练习1、Was it because Jack came late for school _ Mr. Smith got angry?A. why B. who C. where D. that2、It was the culture, rather than the language, _ made it hard for him to adapt to the new environment abroad.A. where B. why C. that D. what3、I
