◆ 强调句型的基本结构
It is/was + 被强调部分 + that/wh (m)+句子其它成分
※ 让我轻轻地告诉您：强调句型可强调的句子成分通常为主语、宾语、地点状语、时间状语等，也可以强调一个从句。但不能用来强调谓语动词，请观察以下句子
原句：I met my ld friend in the park yesterday.
It was in the park that I met my ld friend yesterday.（强调地点状语）It was yesterday that I met my ld friend in the park.（强调时间状语）It was my ld friend that I met in the park yesterday．（强调宾语）It was I wh/that met my ld friend in the park yesterday.（强调主语）
a. It was in the park that we met the freigner this mrning．b. It is ur teachers that／wh ften help us．
◆在强调句型中，如果被强调的部分指人时,可用 wh(m)／that, 其它一律用 that, 请观察以下句子
◆在强调结构中，无论被强调的是人还是物，是单数还是复数, be 动词一律用 is／was，如果原句的谓语动词是一般过去时态，用was.如果原句的谓语动词是一般现在时,则用 is. 有时也可以用“情态动词 + be”形式, 请观察以下句子
a. It is Tm wh/that wins the first prize in the exam．b. It was the wrkers wh/that built the building three years ag．c. It might be yesterday that Alice cleaned the classrm．d. It will be the teacher wh g with yu tmrrw．
◆强调句型的各种句式变化
a. It is my father that/wh is cleaning the flr.b. It was his teacher that/wh helped him yesterday.
●肯定句： It is/was + 被强调部分 + that/wh (m)+句子其它成分, 请观察以下句子
●否定句: It is/was nt + 被强调部分 + that/wh + 句子的其它成分，请观察以下句子
a. It is nt Mary that/wh is playing basketball.b. It was nt Alice that/wh did it last week.
● 疑问句: Is／Was it…that/wh + 句子其它成分 + ?，请观察以下句子
a. It was last year that the building was cmpleted.→Was it last year that the building was cmpleted?b. It is Zhang Ling that/wh is helping the teacher.→ Is it Zhang Ling that/wh is helping the teacher?
a. It was by bike that he went schl.→ Hw was it that he went t schl?b. It was n the playgrund that I came acrss my Englishteacher.→ Where was it that yu came acrss yur English teacher?
● 特殊疑问句：特殊疑问词 + is／was + it + that + 句子其余部分！特殊疑问句是对陈述句中被强调部分划线提问变来的，请观察以下句子
◆ nt…until…结构可用在强调句型中，其结构为：It is／was nt until …that….(句子其它成分), 请观察以下句子
原句：He didn’t came in until the class began.→It was nt until the class began that he came in．原句：He didn’t finished ding his hmewrk.→It was nt until last Friday that he finished reading the bk．
◆当强调主语时，谓语动词应和被强调的人或物在人称和数上保持一致。如果被强调的主语是人，人称代词一般用主格，请观察以下句子
a. It is I wh/that am ging t attend the meeting．b. It is my teacher wh/that helps me with my studies．c. It is the girls that/wh usually dance n the playgrund.
a. It was a lvely cat that culd lk after the baby．(定语从句)b. It was in the garden that Tm grew sme flwers. (强调句型)c. It was seven ’clck when she saw the injured dg.(时间状语从句)d. It was at seven ’clck that she saw the injured dg.(强调句型)e. It is a pity that they didn’t cme t see yu yesterday．(主语从句)
◆强调句型与定语从句、主语从句和状语从句的区别：一般说来，如果把句子中的 It is／was 和 that 去掉，稍加调整语序，能还原句子，且句子意思依然完整，则为强调句型；否则，应为其他句式，请观察以下句子
1. It was _______ it was raining heavily that they had t stay at hme all day． A. because B. since C. fr D. since答案 A. 强调句型只可以强调由 because 引导的原因状语从句，as／since／fr 引导的句子不能用在强调句中。2. He frgets ______ he saw the film.A. that it was when B. when it was that　 C. when was it that D. that was it when答案 B. 分析：假设原句为：
He saw the film when he was three years ld．对时间状语进行强调后为：It was when he was three years ld that he saw the film．再对被强调部分 when he was three years ld 提问变成特殊疑问句：When was it that he saw the film ?再让特殊疑问句作宾语从句后, 疑问语序就变成陈述语序:He frgets when it was that he saw the film.
3. It was the training ______ he had as a yung man ______ made him such a gd engineer．A. what；that B. that；what C. that；which D. which；that答案 D.本句强调主语 the training，而主语后又接 which 引导的定语从句，还原后应为：The training which he had as a yung man made him a gd engineer．4. It was _____ he said and smething he did ______ disappinted me at that time.A. what；that；that B．that；what；that 　C. what；what；that D．what；that；what答案 A. 此题的强调部分是 what 引导的主语从句和 smething ，而 smething 后带有 that 引导的定语从句。
5. Was it thrugh the teacher ____ yu came t realize the imprtance f learning English?A. wh B. whm C. hw D. that答案为 D.强调介词短语 thrugh the teacher，而不是名词 teacher. 选项A、B项具有很强的迷惑性6. It is the yung man ____ lked fr _____ caught the murderer．A. that; wh B. that; they C. they; that D. they; which答案为C.考查了定语从句和强调句型。they lked fr前省略了关系代词 that，that 引导定语从句，同时又在从句中做宾语，可以省略，如果去掉定语从句，强调句为：It is the yung man wh／that caught the murderer．本句意思是：是他们在寻找的那个年轻人抓住了杀人犯
7. Was it seven 'clck ___ yu finished yur task?A. when B. that C. then D. which答案 A. 此题是含有when引导的时间状语从句，不是强调句型。8. She tld us that it was a small muntain village _______ she lived with her grandparents．A. that B. which C. where D. when答案 C. where 引导定语从句，同时又在从句中作状语。
