高一英语强调句型教学教案2010-5-27
1 谓语动词的强调
Do come here tomorrow. He did write to you last week.
Mary does study hard now. 强调谓语，用助动词do, did或does。
2 强调句型的基本结构形式为:It is/was+被强调部分+that/who/whom +句子的其余部分。（*）
在英语中，我们常用It is／was…that结构来突出强调句子的某一成分(（1）一般是句子中主语，宾语或状语等，（2)也可以是从句。（3）其所强调的主语，宾语还可带有自己的定语，同位语（但不能是定语或谓语、表语（主语补语）、让步状语,条件状语)）。强调句型只可以强调由because引导的原因状语从句，不能对 for, as , since , though，although 等引导的从句表示强调。
在这个句型中，it没有词汇意义，只是引出被强调的成分。
(1) I met them at the school gate yesterday.
It was I that (who) met them at the school gate yesterday.
It was them that (whom) I met at the school gate yesterday.
3观察
（a）如果被强调的成分是表示人的词，用who（主格）/ whom（宾格）或that来连接都可以。如果是其它成分，则一律用that来连接。强调句型的主语是it ， 所以，is / was 不受…
(b) 强调主语或宾语且其为人称代词时,应注意其形式仍用主格或宾格形式。
学生做改错题1,2
It was her that told me about it. It is I who the teacher has punished.
强调主语或宾语且其为人称代词时,应注意其形式仍用主格或宾格形式。
4 It is …that …:
Tom often helps me with my English---It is Tom who often helps me with my English.
I am gong to attend the meeting tomorrow.---It is I who am gong to attend the meeting tomorrow.
(当强调的是主语时，其谓语动词应和被强调的人和物保持人称、数的一致。)
（*）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...。
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...。
学生做改错题3.
It is I who/ that is going to be sent there to help them. 强调主语时,谓语动词应与之保持一致。
(2) We knew what had happened when he came back home——It was when he came back home that we knew what had happened .
He didn’t come to school yesterday because he was seriously ill. ——It was because he was seriously ill that he didn’t come to school yesterday .
What he said disappointed me at that time.——It was what he said that disappointed me at that time.
I just wonder what makes him so excited. ----- I just wonder….
(3) 其所强调的主语，宾语还可带有自己的定语，同位语：
The training( that / which )he had as a young man made him such a good engineer.----It was the training (that/ which) he had as a young man that made him such a good engineer.
同位语:学生做 练习：用强调句型强调下列各句中的划线部分。
1) I am gong to attend the meeting tomorrow.
2) I met the foreigner from Canada when I was visiting the Great Wall.
5 下列各句均为强调句型，请将它们恢复为一般句型。
方法：1）移开 2）适当调整语序（不要自己增加或减少词汇）
eg: It was in the street that she met the old teacher. （地状）
1). It is the monitor who wins the first prize in the exam. （强调主语）
2). It was on October 1st, 1949 that new China was founded.（时状）
3). It was me that you met yesterday. （宾语）
4). It was because she was ill that they didn’t ask her to do the job. （强调原因状语从句）
5). 宾从20 I just wonder ___ that makes him so excited.
A. why it does B. what he does C. how it is D. what it is 【06山东32】
6否定句的强调句和一般疑问句的强调句： It is / was not +被强调部分+that/who/whom +句子的其余部分。 Is / Was it +被强调部分+that/who/whom +句子的其余部分。
7特殊疑问句的强调句（特殊疑问句的强调句其实是强调特殊疑问句中的疑问词）
It was in the street that she met the old teacher.----Where was it that she met the old teacher?
构成：“特殊疑问词+was(is) it that + 句子的其余部分”构成的。
练习 Where did you find the wallet?----Where was it that you found the wallet？练习：1)2)3)4)
When shall we meet?----When is it that we shall meet?
When did you return the book to me?----When was it that you returned the book to me?
Where did the road accident happened yesterday?--- Where was it ____ the road accident happened yesterday?
8 将“练习：1)2)3)4)”加上I really don’t know…（即改为宾从）
例如：I really don’t know…Where was it that you found the wallet？
I really don’t know where it was that you found the wallet？
当含有特殊疑问词的强调句型用在宾语从句中的时候，上述句型应改为‘特殊疑问词+it was( is) that +陈述句”，即采用陈述句语序。
学生做二 考题组

考题A : Where was it ____ the road accident happened yesterday? B: In front of the market. A. when B. that C. which D. how
8 not … until 句型中，若要强调until引导的时间状语（从句），必须将not前移，写成It is/was not until … that … ．
Her husband didn’t arrive home until late in the evening---It was not until late in the evening that her husband arrived home .
He didn’t come in until the class began.----It was not until the class began that he came in.

9 强调句与其他含有 it 的句型的比较：（p.15.）It is/was+时间段+since从句（从……已多久了）；It +be+时间段+before从句（Before前的主句如果是肯定的，翻译成“在……之后才……” 主句如果是否定的，翻译成“不久就……”），
It is/was+时间（表示时间的名词）+when从句 (it指时间，when引导的是时间状语从句)
e.g.（1）It is five months since I arrived in New York. 我到纽约已经五个月了。
（2）It was long before he gave an answer. 过了好久他才答复我。
（3）It was not long before he worked out the difficult maths problem.不一会儿他就把那道数学题解出来了。
（4）It will be years before he comes back. 过几年他才回来。
（5）It was seven o’clock when we reached the mountain village.（时间状语从句）
一般句型，时间以名词的方式表达，用来作表语。
比较：It was at seven o’clock that we reached the mountain village.（强调句型）
强调句型，被强调的时时间状语，因此用介词短语表达
（6）强调地点和where引导的定语从句的例句：
It was the school gate ______ I met an old friend of mine after class .
It was at the school _____ I met an old friend of mine after class.
A. that B. which C. where D. why
小结：含有 it is/ was…的句子并非一定是强调句型，一般说来，如果把句中的It is/ was … that去掉，稍加调整语序，能还原成完整句子，并且句子意思依然完整，则为强调句型；否则，应为其他从句。另外，我们还可以通过判断It是否有所指代来判断（强调句型中，it没有词汇意义，只是引出被强调的成分）例如：It is clear that not all boys like football.
_____ is our belief that improvements in health care will lead to a stronger, more prosperous economy. A. As B. That C. This D. It
-----is no possibility that Bob can win the first prize in the match. A. There B. It

4）It was not long ____ I forgot it all A. that B. when C. after D. before
5）It was three years ____he had been a student. A.since B.that C.then D. after
在这类句子中，终止性动词表示从动作发生时算起；如果是状态动词或持续性动词，则从动作或状态结束时算起。
6). It will be many years _____ the chemicals start to escape from the containers.
A. after B.before C. that D. when
7). It won’t be ten minutes _____ he finishes writing the composition.
A. when B before C. that D. which
10. 在强调结构中，无论被强调的是人还是物，单数还是复数，be动词一律用is/was形式，有时,be前可使用表示推测的情态动词构成复合结构。 It must be…that…和It must have been...that... It might be ...that ...,的句型表示强调。

1 It _____ at Christmas that John Smith gave Mary a handbag.
A. must have B. will be C. might have been D. may have had

(b)在这个句型中，it没有词汇意义，只是引出被强调的成分。
（c）如果被强调的成分是表示人的词，用who（主格）/ whom（宾格）或that来连接都可以。如果是其它成分，则一律用that来连接。强调句型的主语是it ， 所以，is / was 不受…
(d)当强调的是主语时，其谓语动词应和被强调的人和物保持人称、数的一致。
(e) 强调主语或宾语且其为人称代词时,应注意其形式仍用主格或宾格形式。
3）否定句的强调句： It is / was not +被强调部分+that/who/whom +句子的其余部分。
4)一般疑问句的强调句: Is / Was it +被强调部分+that/who/whom +句子的其余部分。
5)特殊疑问句的强调句构成：“特殊疑问词+was(is) it that + 句子的其余部分”构成的。
6)当含有特殊疑问词的强调句型用在宾语从句中的时候,上述句型应改为‘特殊疑问词+it was( is) that +陈述句”，即采用陈述句语序。
7 )not … until 句型中，若要强调until引导的时间状语（从句），必须将not前移，写成:
It is/was not until … that … ．
8 强调句与其他含有 it 的句型的比较：
1）It is/was+时间段+since从句（从……已多久了）；
2）It +be+时间段+before从句（Before前的主句如果是肯定的，翻译成“在……之后才……” 主句如果是否定的，翻译成“不久就……”），
3）It is/was+时间（表示时间的名词）+when从句 (it指时间，when引导的是时间状语从句)
9在强调结构中，无论被强调的是人还是物，单数还是复数，be动词一律用is/was形式，有时,be前可使用表示推测的情态动词构成复合结构。
It must be…that…和It must have been...that... It might be ...that ...,的句型表示强调。
10 )判断一个句子是否是强调句型的方法：
含有 it is/ was…的句子并非一定是强调句型，一般说来，如果把句中的It is/ was … that去掉，稍加调整语序，能还原成完整句子，并且句子意思依然完整，则为强调句型；否则，应为其他从句。另外，我们还可以通过判断It是否有所指代来判断（强调句型中，it没有词汇意义，只是引出被强调的成分）
例如：It is clear that not all boys like football.
