nt ……until 强调用法
1、陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ wh（当强调主语且主语指人）+ 其它部分eg. It was yesterday that he met Li Ping.2、一般疑问句的强调句型：Is/ Was it + 被强调部分（通常是主语、宾语或状语）+ that/ wh（当强调主语且主语指人）+ 其它部分eg. Was it yesterday that he met Li Ping?3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ wh + 其它部分？eg. When and where was it that yu were brn?
针对I met Li Ming at the railway statin yesterday.句子进行强调。强调主语：It was I that (wh) met Li Ming at the railway statin yesterday. 强调宾语：It was Li Ming that I met at the railway statin yesterday.强调地点状语：It was at the railway statin that I met Li Ming yesterday.强调时间状语：It was yesterday that I met Li Ming at the railway statin.
注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, wh，即使在强调时间状语和地点状语时也如此，that, wh不可省略；强调句中的时态只用两种，一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时，用It was … ，其余的时态用It is … 。
1、It is/ was … that … 结构不能强调谓语，如果需要强调谓语时，用助动词d/ des或did。D sit dwn. 务必请坐。He did write t yu last week. 上周他确实给你写了信。D be careful when yu crss the street. 过马路时，务必（千万）要小心啊！2、注意：此种强调只用d/ des和did ，没有别的形式；过去时用did ，后面的谓语动词用原形。
nt … until … 句型的强调句
1、句型为：It is/ was nt until + 被强调部分 + that + 其它部分普通句：He didn’t g t bed until/ till his wife came back.强调句：It was nt until his wife came back that he went t bed.2、注意：此句型只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was nt … 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。
知识点：连接词 一般说来，如果被强调部分是人时，用连词that或wh；被强调的部分是宾语，指人时也可以用whm；如果被强调部分是物，只能用连词that。如：It was Jhn and Mike wh/that saw Mary in the street last night.It is Mary whm/wh he ften helps. It was in the street that I met him yesterday.
知识点：不同的强调成分 如：Mary met an ld beggar in the street yesterday. (强调主语) It was Mary wh/that met an ld beggar in the street yesterday. (强调宾语) It was an ld beggar whm/that Mary met in the street yesterday. (强调时间状语) It was yesterday that Mary met an ld beggar in the street. (强调地点状语) It was in the street that Mary met an ld beggar yesterday.
有时，be前可使用表示推测的情态动词。如：It must be Peter wh has let this secret ut. It might be last night that they did their hmewrk.
知识点：时态 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 ; 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 如：It's Mary wh/that meets an ld beggar in the street. It's Mary wh/that is ding the husewrk. It's Mary wh/that has dne such terrible things. It's Mary wh/that will have finished this task by the next week.It's Mary wh/that will be ging t America. It's Mary wh/that will g t see the dctr tmrrw.
的强调句 强调含有nt until的句子时，nt 位于until从句前，主句谓语动词作相应变化，即it is(was)+nt until从句+that +其它。如：普通句：He didn't g t bed until/ till his wife came back. 强调句：It was nt until his wife came back that he went t bed. It was nt until he had finished the wrk that he went hme. It was nt until 12 ’clck last night that my brther came hme.
强调句的疑问句 强调一般疑问句中的某一成分时，要在主句中用一般疑问句的顺序。如：Was it yu that/wh brke the windw ? Was it in the war that he lst his sn ? 强调特殊疑问句中的疑问词，其结构模式是：“疑问词+ is/was + it +that...”。它同感叹句的强调模式极其相似，首先将疑问句开头的部分作为强调部分，套入强调结构，然后再将其变为疑问句。如：Where were yu brn? → Where was it that yu were brn? What did yu want t see? → What was it that y u wanted t see? Hw many peple are being trained fr the imprtant wrk? → Hw many peple is it that are being trained fr the imprtant wrk ?
强调句型中的主谓一致 被强调的成分为原句的主语时，that/wh之后的谓语动词应与被强调的名词或代词在人称和数方面保持一致关系，从而选用恰当的动词形式。如：It is yu wh/that are wrng. It is I wh/that am answering the questin.
注意1：但是如果被强调的部分是人称代词，按理应用人称代词主格形式，但在口语或非正式文体中也可以用其宾格形式，此时that/wh的谓语动词要用单数第三人称形式is或was。如：It is me/I wh is being asked the favr. 注意2：在It is/was..., 句型中，其谓语动词应与肯定部分的词保持一致关系。如：It is my brther, nt I that studies in that schl. It is yu, nt yur sister that are in charge f the cmpany.
感叹句的强调结构既要体现强调句型的形式特征，又要体现感叹句的自然语序。如：Hw happy he lks! → Hw happy it is that he lks! What a clever by he is! → What a clever by it is that he is!
“It is / was + 形容词 / 分词 / + that从句”是主语从句，若删去“It is / ”，则原句不成立，It 为形式主语，真正主语为that后跟部分；而强调句型若删去“It is / / wh...”，原句结构与语意均完整，译成中文时，常可加上“正是……”“就是……”之类字眼。
1. 强调句与主语从句的区别
It is true that he is hnest. It is knwn t all that China is a cuntry with a lng histry. It was here that he fell ff his bicycle.
识别下列从句，并比较其中文意思
It is true that he is hnest. (主语从句) It is knwn t all that China is a cuntry with a lng histry. (主语从句)It was here that he fell ff his bicycle.(强调句)
在被强调的名词后再设计一个以该名词为先行词的定语从句，这时不要把定语从句当作强调句。It was this schl where (in which) he nce studied that gave him a chance f teaching.
2. 含有定语从句的强调句型
3. 强调句型与状语从句的区别
It was at 7:00 that I arrived. It was 7:00 when I arrived.It was tw years ag that I began t learn drawingIt is(has been) tw years since I began t learn drawingIt was tw years befre they came t see us. It was tw years later that they came t see us.It wn’t be lng befre we graduate frm the schl. It will be tw years befre we graduate frm this university.
It was at 7:00 that I arrived. (强调句型，强调时间状语at 7:00) 正是在7:00时，我到了。It was 7:00 when I arrived. (时间状语从句，在7:00前无介词at) 当我到达时， 时间是7:00。It was tw years ag that I began t learn drawing.(强调句型，前后时态一致) 正是在两年前我开始学习绘画。It is(has been) tw years since I began t learn drawing. (since引导的时间状语从句，前后时态不一致) 自从我学习绘画以来已经有两年了。
It was tw years befre they came t see us. (时间状语从句) 过了两年后他们才来看我们。It was tw years later that they came t see us.(强调句型) 正是两年后他们才来看我们的。It wn’t be lng befre we graduate frm the schl. (时间状语从句) 不久我就将毕业了。It will be tw years befre we graduate frm this university. (时间状语从句) 再过两年我们就将大学毕业了。
试用强调句表达“我觉得物理太难了”找出被强调的部分选择强调句的时态将被强调部分放入it is/was…that…结构中照抄其他部分It was physics that I fund extremely hard.It was because I didn’t finish my physics exercises n time that it became a headache fr me in the exam.
