概要写作几个提分句型1---强调句

It was in this shop that he bought the book yesterday.
【注意】
1.在该强调结构中，It 无任何意义但不可以换成this或者that等。 It is (was)…that (who)…为结构词，假如去掉，剩下部分在语法结 构和句子含义上均完整，这一点正是它和定语从句等的本质区别。
It was in this shop that he bought the book yesterday.
强调句
It was the shop that he bought the book yesterday.
定语从句
2. 关于that与who： 当被强调部分指人时，可以用who（被强调部分的人作主语或宾 语时）或者whom（被强调部分的人作宾语时)代替that；
如果被强调的成分有同位语，同位语也应提前。 It was from him，his chemistry teacher，that Paul learned to watch carefully in class．
3.关于be的适当形式：
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 词一律用单数is/was形式。
当被强调部分指物时通常用that；当被强调部分既包括人又包括 物，用that不用who
It was the things and people that they remembered that they were talking about． 当被强调部分是代词时，用who不用that。 当强调时间或地点或原因状语时，不能用when / where /why代 that(尤其是当这些状语为介词短语时)。
②如果原句的谓语动词时态是过去范畴(一般过去时、过去进行时、 过去完成时、过去将来时等)，就用was。例如: It was between 1989 and 1999 _____ great changes took place in our hometown. A. when B. that C. which D. because
1）It was only when I reread his poems recently ____ I began to appreciate their beauty. A. until B. that C. when D. so 2）It was in Qingdao _____ I saw the sea for the first time. A. what B. that C. when D. which 3）It was because of bad weather ____ the football match had to be put off. A. so B. so that C. why D. that
一.强调句
强调句常用来突出说话人要强调的语言信息，给对方以强烈的 印象和感受。译成汉语时，常加上“正是 …”等字眼。

其基本结构是：It+ be的适当形式+被强调成分+that (who)+其他成 分
He bought the book in this shop yesterday.
→强调主语： It was he that bought the book in this shop yesterday. →强调宾语： It was the book that he bought in this shop yesterday. →强调地点状语：
①如果原句的谓语动词时态是现在范畴(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)，就用is。
It is the ability to do the job _____ matters not where you come from or what you are. A. one B. that C. what D. it
③也可以根据需要用It may/might/must be…that/who…; It must have been… that/who… 如 It might be Sally that you are thinking of. It might be in the morning that he broke into the house. It must be John that/who will take part in the contest on behalf our class. It must have been his brother that you met.
特别提示：
对“not...until...”结构的强调，要用“It is/was not until...that...”这 一固定句型。由于否定已经前移，that后只能用肯定形式。同时要 注意不能使用倒装语序.
It was not until midnight that he went back home after the experiment. (湖北04)
例1．It is these poisonous products that can cause the symptoms of the flu, such as headache and aching muscles. (NMET03)
It was at the gate of our school that we gave the visitors a warm welcome. (强调地点状语)
4. 关于被强调成分。
在强调句型中，能够被强调的句子成分通常为主语或宾语（名词、 代词）、状语（介词短语、时间或地点状语从句或者because引导原 因状语从句）等，但不能强调谓语动词、表语或补语（形容词或名 词充当）、although引导的让步状语从句、for、since, as引导的原因 状语从句、if条件状语等。
