when放在句子开头和放在句子中间有什么不同

when可当疑问副词,也可当关系副词.1. when当疑问副词, 一定是放在句首.例: When is the play going to start? 这场戏什麽时候要开始?2.when当关系副词, 用来修饰表时间的先行词, 可用来代替"时间介系词+which",如" at which, in which"例: Do you remember the day THAT I invited you out? 记得我邀你出去的那一天吗?=Do you remember the day WHEN I invited you out?=Do you remember the day ON WHICH I invited you out?=Do you remember WHEN I invited you out? (这里的when引导名词子句作受词用) 3.when(当.....) 主要用於强调事情发生的时间. 用在句首或句中意思并没有差别例: When her name was called, she stood up.= She stood up when her name was called.叫她名字的时候,她站了起来.但注意, when在句首, 两个句子之间要用逗号隔开, when在句中, 就是一个句子.

whendoyou造句3个句子

你好!when do you造句3个句子:1When do you think you can return with streetperformances?你估计什么时候能把街头表演部分拿出来?2When do you get up?你什么时候起床?3When do you go to school?你什么时候去学校?4When do you sleep?你什么时候睡觉?

请大家帮忙分析一下,句中的that是引导的从句吗?when 引导的是什么...

1、that此处不是引导从句,因为that不光是连词还是指示代词,此处“that leisurely age”译为“那悠闲的年代”。

2、此处“when”是连词,引导定语从句,修饰“age”。

全句意为“Harriet 婶婶/阿姨住在那有雇来的仆人做家务的有线年代。

it's…… ,when……这是什么句式?

It's...when. It's....before等等都不是强调句强调句 (一)强调句句型 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/ who(当强调主语且主语指人)+ 其它部分。

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/ who + 其它部分? not … until … 句型的强调句 1、句型为:It is/ was not until + 被强调部分 + that + 其它部分 强调句 (一)强调句句型 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/ who(当强调主语且主语指人)+ 其它部分。

e.g. It was yesterday that he met Li Ping. 2、一般疑问句的强调句型:同上,只是把is/ was提到it前面。

e.g. 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/ who + 其它部分? e.g. When and where was it that you were born? 4、强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调。

强调主语:It was I that (who) met Li Ming at the railway station yesterday. 强调宾语:It was Li Ming that I met at the railway station yesterday. 强调地点状语:It was at the railway station that I met Li Ming yesterday. 强调时间状语:It was yesterday that I met Li Ming at the railway station. 5、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, who,即使在强调时间状语和地点状语时也如此,that, who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 … 。

(二)not … until … 句型的强调句 1、句型为:It is/ was not until + 被强调部分 + that + 其它部分 e.g. 普通句:He didn't go to bed until/ till his wife came back. 强调句:It was not until his wife came back that he went to 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 not … 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。

(三)谓语动词的强调 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do/ does或did。

e.g. Do sit down. 务必请坐。

He did write to you last week. 上周他确实给你写了信。

Do be careful when you cross the street. 过马路时,务必(千万)要小心啊! 2、注意:此种强调只用do/ does和did ,没有别的形式;过去时用did ,后面的谓语动词用原形。

It be 时间段 before 从句 :多久之后才....It will be 一段时间before 一般现在 :将来过多久才It was 一段时间before 过去时 :不久就...it's... when 没什么特殊用法给你造个句子吧it's 3 o'clock when he gets home

when后引导的不都是句子吗

when 后面可以加句子。

when 后面可以加doing。

when 后面可以加done。

给你例句:When I heard the news, I was excited.When hearing the news, I was excited.这两句话都正确,且表达同一个意思。

When (I was) told the news, I was excited.done 是在表示被动的时候才用的。

当我被告知这个消息,我很激动。

括号里面内容省略,实际上也是省略句。

如满意,请采纳!
