“When”作连词时的用法及译法总结
“When”作连词时的用法及译法总结对英语学习者来说，when是一个常见的单词，所以一看到when就会脱口而出“当……时候”.这种翻译有时会闹出笑话甚至与其本意“南辕北辙”.因此，熟练掌握when作连词时的几种用法尤为重要。
小编结合自己的教学经历对when的用法及译法做如下总结：一、When作从属连词，引导状语从句1. when 译为“当……时候”这是when 最基本的用法，引导时间状语从句。
1）从句可放句首或句末。
放句首时，从句后面用逗号；放句末时，不用逗号。
【典例】The whole world were very anxious when themissing Malaysia Airlines Flight MH370 was reported.当马航失联客机MH370被报道时，世人都很着急。

when 表时间。
句意为：“当你们有相似的兴趣时，你们会更容易成为朋友。
”所以答案是B.2）when既可引导持续性动作，又可引导短暂性动作。
它可以表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。
【典例】When I came here, I saw Mary reading English.当我到这儿时，我看到玛丽在读英语。
Many people were killed or injured when the policearrived at the Kunming railway station at night on March 1,2014. 2014年3月1日晚，当警察到达昆明火车站时，已有许多伤亡。
3）从句中常用一般现在时替代一般将来时，用一般过去时替代过去将来时。
【典例】I will tell him the news when he comes heretomorrow.明天他来时，我将告诉他这则消息。
They would be excited when they knew their grades.当他们知道他们的成绩时，他们会很激动的。
2. when 译为“一/刚……就”1）when 相当于as soon as /immediately/instantly/directly等词的意思，引导时间状语从句。
【典例】We will start when the monitor comes. 班长一来，我们就出发。
2）when用于固定结构“hardly/scarcely…when…”.此时when 可换作before. 注意：当把hardly/scarcely放句首时，句子需部分倒装。
【典例】I had hardly arrived home last night when itbegan to rain.Hardly had I arrived home last night when it began torain.昨晚我一到家，天就下雨了。

句意为：“我刚到办公室，我妻子就打电话让我立刻回家。
”本句是“hardly…when…”结构，表示“刚……就……”,故答案选A.3. when 译为“如果……”when相当于if,引导条件状语从句。
【典例】Turn off the light when nobody is in theclassroom.如果教室没人了，把灯关上。
Smog will be distant from us when everyone fightsagainst pollution.如果人人都与污染作斗争，雾霾就会远离我们。
4. when译为“虽然，尽管”when引导让步状语从句，相当于though/although/as.【典例】He usually walks when he might ride.虽然可以坐车，他通常总是步行。
5. when译为“既然，考虑到”when引导原因状语从句，此时相当于since“既然”.【典例】How can you expect to learn anything when younever listen? 既然你从来都不听，你怎能期望有所收获呢？Why use metal when you can use plastic? 既然能用塑料，为什么要用金属呢？How could you , when you know that it's impolite tostare at others for a long time?既然你知道长时间盯着别人看是不礼貌的，那你怎么还这样做呢？【典例】—It cost me 30 yuan to come here.—Well, it was crazy of you to take a taxi you wouldcome by bus as well.A.whenB.whileC.unlessD.because解析此题考查状语从句连接词。

”6. when译为“然后”【典例】I stayed till noon, when I went home.我呆到中午，然后就回家了。
二、when 作并列连词，引导并列分句when译为“突然……或这时……”.可用在四种句式中，表示一个动作“正在发生”、“即将发生”、“刚刚完成”突然插入另一个动作。
when相当于and just time 或and just atthat time.此用法也是高考的高频考点。
1. was/were doing…when…正在做……这时/突然……【典例】I was walking along the river when I heard a drowningboy crying for help.我正沿着河边走，突然听到一个溺水儿童的呼救。

”所以答案是A.三、when作从属连词，引导名词性从句when引导名词性从句，在从句中作时间状语，意为“什么时候”.从句常包括主语从句、宾语从句、表语从句和同位语从句。
此时注意：从句要用陈述语气。

as 的用法
as可以作连词、介词及关系代词。
现将其用法小结如下:一、as作连词的用法:1. 作"当……的时候",引导时间状语从句。
注意与when、while的用法区别。
①when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。
如:When he was at college, he could speak several foreign languages.When the clock struck twelve, all the lights in the street went out.②while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。

while用法
while用法He's out banging other women over the head with a club, while she sits at home trying to get the mastodon smell out of the carpet!---《老友记》第一季第二集He's out banging other women over the head with a club根据说话人的意思，这句话的中文意思是“他在外面到处沾花惹草”club在这里的作名词，是“棍棒，球棒”的意思。
如果直译，本句可译为：“他到外面用棍棒打女人们的头”；不过，bang在粗俗的口语中有“和...发生关系”的意思，因此，本句应该是“他在外面到处沾花惹草”的一种隐喻的说法。
