??1．it引導的強調(diào)句型，通常形式為：It＋be＋被強調(diào)部分＋that／who＋其它。這種強調(diào)句由普通陳述句轉(zhuǎn)換而來，用來強調(diào)句子的主語、賓語或狀語。例如：
??Karl bought Marva a bicycle on her birthday．卡爾在瑪瓦生日那天給她買了一輛自行車。
??It was Karl that／who bought Marva a bicycle on her birthday．（強調(diào)主語）
??It was Marva for whom Karl bought a bicycle on her birthday．（強調(diào)間接賓語）
??It was a bicycle that Karl bought Marva on her birthday．（強調(diào)直接賓語）
??It was on her birthday that Karl bought Marva a bicycle．（強調(diào)狀語） ______ she first heard of the man referred to as a specialist．?
??A）It was from Stephen?
??B）It was Stephen whom?
??C）It was from Stephen that?
??D）It was Stephen that （B4．1990．1－48，C對。強調(diào)狀語）她是從斯蒂芬那兒第一次聽說被稱為專家的那個人。 It was the training that he had as a young men ______ made him such a good engineer．
??A）that
??B）has
??C）what
??D）later
? （1999年全國大學生英語競賽初賽試題，強調(diào)主語）A對。正是他年輕時候接受的訓練使他成為一名優(yōu)秀的工程師。（試比較： The training that he had as a young man made him a good engineer．）
??但是這種句型通常不用來強調(diào)表語，例如我們不說：＊It is a teacher that he is． 2．注意區(qū)別強調(diào)句中的that／who分句與定語從句：
??It was the student that／who asked the silly question．是一個學生問了這么一個愚蠢的問題。（分裂句）
??He was the student who asked the silly question．他就是問了這么一個愚蠢問題的學生。（劃線部分是定語從句）
??3．在含有until時間狀語的否定句中，如果強調(diào)時間狀語，就成了it is ／was not until．．．that．．．．例如：
??We did not begin studying French until we entered university．我們進了大學才開始學法語。 要強調(diào)until we entered university，就成了：
??It was not until we entered university that we began studying French． ______ the 18th century that man realized that the whole of the brain was involved in the workings of the mind．
??A）During
??B）In
??C）It was until
??D）It was not until D對。直到十八世紀，人們才意識到：心理活動與整個大腦有關。
??4．這種句子也可能是疑問句：
??Why is it that you hate winter？你究竟為什么不喜歡冬天？
??How was it that you missed such a wonderful lecture？你怎么會錯過這么精彩的報告？
??When was it that they went abroad？他們什么時候出國的？
?? 5．這種結構還常常出現(xiàn)在諺語里，表示"無論怎樣……都不……"，是一種反語式的強調(diào)用法；原來是莎士比亞時代的用法，所以現(xiàn)在容易出現(xiàn)理解上的錯誤。例如：
?? It's a wise father who knows his own child．無論多聰明的父親也不見得了解自己的孩子。 It's an ill wind that blows nobody（any） good．此失則彼得，沒有使所有的人都受害的壞事。
