when能前后都接一般现在时可以吗?
when可以引导多种从句或特殊疑问句。根据不同的语境,它既可以放在句首也可以放在句中。
when
读音:英 [wen]? 美 [wen]?
释义:什么时候,何时,什么情况下。
语法:when的基本意思是“什么时候”。可用作疑问副词,用来询问某事曾发生或将要发生的时间,引导特殊疑问句,还可用作关系副词引导限制性定语从句、非限制性定语从句和表语从句,表示“是…时候的事”。
例句:
I?asked?him?when?he'd?be?back?to?pick?me?up?
我问他什么时候回来接我。
扩展资料when的近义词:while
while
读音:英 [wa?l]? 美 [wa?l]?
释义:当…的时候,与…同时。
语法:while还可引导让步状语从句,意思是“虽然,尽管”,含有对比意味。while表示对比关系时,意思是“而,然而”。
例句:
They?walked?on?in?silence?for?a?while.
他们继续默默无语地走了一会儿。
英语选择题中有when的怎么答?
当然可以。
当在用when引导一个状语从句描述正在发生的事,或者谈论一个日常现象,主句和从句都应该用现在时。
例:Please do not talk when I am speaking to you.
When 的用法
一、作为副词,它有以下的用法:
1. 作为疑问副词,引导特殊疑问句,意为“什么时候;何时”。
如: ( 1 ) When will they come back?
( 2 ) What time will they come back?
回答 when 引导的从句,不一定指出具体的时间点。如回答句( 1 )可用 tomorrow, next month 等。而回答 what time 引导的问句,则必须说出具全的时间点,如 at two o'clock, at five past ten 等。
2. 作连接副词,引导名词性从句或不定式,意为“什么时候”。从句使用陈述句语序,时态根据实际情况而定。
如: ( 1 ) I'd like to know when they will come. 我想知道他们什么时候来。( when 引导宾语从句)
( 2 ) Can you tell me when the bank opens? 你能告诉我银行什么时候开门吗?( when 引导宾语从句)
( 3 ) When she'll be back depends much on the weather. 她何时回来在很大程度上取决于天气。( when 引导主语从句)
( 4 ) He you decided when to go sightseeing? 你们已经决定什么时候去郊游了吗?( when 引导不定式结构)
3. 作疑问代词,常和介词 since, till, up to 等连用,意为“什么时候”。
如: ( 1 ) Since when he they had the house? 他们从什么时候起有这幢房子的?
( 2 ) Till when is the library open? 图书馆开放到几点呢?
4. 作关系副词,引导限制性定语从句和非限制性定语从句。
如: ( 1 ) The days are gone forever when the Chinese people were looked down upon. 中国人民被人轻视的日子一去不复返了。
( 2 ) The main school holidays are from mid-December till early February, when the days are long and warm. 学校的主要期是从 12 月中旬到 2 月初,这段时间里白天长而且很温暖。
( 3 ) Considering (the time) when these paintings were done, they are in excellent condition. 考虑到这些油画的创作时期,它们保存的状况是极好的。
( 4 ) Do you remember (the time) when the three of us went on a picnic? 你还记得我们三个人去野餐的那段时光吗?
在定语从句中, that 在某些条件下可用来代替 when ,这时其先行词通常是 time, day, moment, year 等。
如: ( 1 ) His mother died on the evening that he was born. 他母亲死于他出生的那晚。
( 2 ) I stay at home on the days that I am not busy. 在我不忙的时候,我就呆在家里。
在某些含有“时间”的名词词组后面,由于该名词不表示时间,或整个名词词组已用作连词,所以不用 when 引导。如: the moment, the instant, the minute, the second 等等,意为“一……就……”,引导时间状语从句。
如: ( 1 ) The first time I went to China, I visited Beijing. 我第一次来中国就游览了北京。
( 2 ) I thought her nice and honest the first time I met her. 我第一次见到她时就认为她很诚实。
( 3 ) The instant I saw him I knew he was my brother. 我一看到他就知道他是我兄弟。
二、作为从属连词,引导状语从句,表示多种语法意义:
1. 表示时间,意为“当……时;在……的时候”。
A. 在时间、条件等状语从句里,用一般现在时表示将来时;当需要表达将来完成的意义时,必须使用现在完成时来代替。
如: ( 1 ) When you see him, please say hello to him. 见到他时,代我问他好。
( 2 ) When you he finished your experiment, please tidy the lab and put everything back in the cupboards. 当你们做完实验后,请把实验室整理好并把物品放回柜子中。
B. 表示过去发生的事情,在 when 引导的时间状语从句的主从复合句中,动作发生在先的用过去完成时,在后的用过去时。
如: ( 1 ) When I was in Japan, I bought some beautiful pearls. 我在日本时,买了一些漂亮的珍珠。
( 2 ) When I reached the station, the train had left. 当我到达火车站时,火车已经开走了。
2. 表示前面的叙述所没有提到过的信息。它总是对所描述的予以引人注目的强调,意为“这时;突然”;当位于句末的分句具有引种用法时,大致有以下三种情况:
A. when 分句前面的分句使用过去进行时。
如: ( 1 ) He was still smiling when the door opened and his wife came in. 他正笑着的时候,门突然开了,他妻子走了进来。
( 2 ) I was thinking of this when I heard my name called. 我正想着这件事时,突然听到有人叫我的名字。
B. when 分句前面的分句使用 was (were) about to, was (were) on the point 等。
如: ( 1 ) We were about to start when it began to rain. 我们刚要出发就开始下雨了。
( 2 ) He was on the point of leing when someone knocked at the door. 他刚要走就有人敲门。
C. when 分句之前的分句用过去完成时,其中 sb had hardly / scarcely /barely … when 已成为固定词组。如:
( 1 ) We had hardly fallen asleep when the bell rang. 我们刚刚入睡,铃声就响了起来。
( 2 ) He had scarcely arrived when he had to lee again. 他刚刚到达就又要离开了。
3. 表示条件,相当于 if ,引导条件状语从句。
如: How can I get a job when I can't even read or write? 如果我连读和写都不会,我怎么能找到工作呢?
4. 表示对比,主要有以下两种情况:
A. 相当于 whereas, while, since, 意为“既然;然而”。
如: ( 1 ) How can I help them to understand when they won't listen to me? 既然他们不愿听我的,我又怎么能帮助他们弄明白呢?
( 2 ) They he only three copies when we need five. 他们只有三本,而我们却需要五本。
B. when 从句中使用虚拟语气,意为“本来……却……”。
如: ( 1 ) She paid when she could he entered free. 本来可以免费入场,而她却付了款。
( 2 ) She stopped trying when she might he succeeded next time. 她本来下次有可能获得成功,但她却不再尝试了。
( 3 ) They were gossiping, when they should he been working. 他们本该工作,却在那里说别人的闲话。
5. 由 when 等引导的状语从句,如果主语与主句的主语一致或是 it ,谓语动词又含 be 动词时,主语和 be 动词常常被省略,就变成“ when + V-ing/ V-ed/ adj/ 介词词组”的结构。
如: ( 1 ) When in Rome, do as Romans do. 入乡随俗。
( 2 ) When (we are ) young, we are full of hope. 年轻时,我们大家总是充满希望。
( 3 ) Don't reach sideways when standing on a ladder. 站在上时,不要侧着身子去够东西。

用what、where、who、when、why开头各造5个的句子
when引导的句子前后时态如下:
when引导时间状语从句:表示有规律的,都用一般现在时;表示将来的事情,用主将从现;表示过去两个有先后的动作,都用过去式;表示一个动作正在进行(过去进行时),另一个动作插入(过去式)。
如果是宾语从句,那么时态问题就参考宾语从句的做法。
如果是时间状语从句,则基本有4种:
1、表示有规律的,都用一般现在时。
如:Water turns into steam when we heat it.
2、表示将来的事情,用主将从现(主句将来时,从句一般现在时)。
如:I will tell him when he comes back.
3、表示过去两个有先后的动作,都用过去式。
如:When he came back, I told him the news.
4、表示一个动作正在进行(过去进行时),另一个动作插入(过去式)。
