“When”作連詞時的用法及譯法大盤點(diǎn)
“When”作連詞時的用法及譯法大盤點(diǎn)作者/袁鳳蘭
對英語學(xué)習(xí)者來說，when是一個常見的單詞，所以一看到when就會脫口而出“當(dāng)……時候”.這種翻譯有時會鬧出笑話甚至與其本意“南轅北轍”.因此，熟練掌握when作連詞時的幾種用法尤為重要。筆者結(jié)合自己的教學(xué)經(jīng)歷對when的用法及譯法做如下盤點(diǎn)：
一、When作從屬連詞，引導(dǎo)狀語從句
1.when 譯為“當(dāng)……時候”
這是when 最基本的用法，引導(dǎo)時間狀語從句。
1）從句可放句首或句末。放句首時，從句后面用逗號；放句末時，不用逗號。
【典例】The whole world were very anxious when the missing Malaysia Airlines Flight MH370 was reported.當(dāng)馬航失聯(lián)客機(jī)MH370被報(bào)道時，世人都很著急。
When he was yet a child, he was fond of swimming.當(dāng)他還是個孩子的時候，就喜歡游泳。
It was March 22,2014 Michelle Obama delivered a speech at Peking University.
A.that B.when C.since D.before
解析 此題考查when 的用法“當(dāng)……時候”.句意為：“米歇爾·奧巴馬于2014年3月22日在北京大學(xué)演講�！�
【高考鏈接】 （2013年安徽卷） It's much easier to make friends you have similar interests.
A. unless B. when C. even though D. so that
解析 此題考查狀語從句的連接詞。when 表時間。句意為：“當(dāng)你們有相似的興趣時，你們會更容易成為朋友�！彼源鸢甘荁.
2）when既可引導(dǎo)持續(xù)性動作，又可引導(dǎo)短暫性動作。它可以表示主句的動作和從句的動作同時發(fā)生，或從句的動作發(fā)生在主句動作之前。
【典例】When I came here, I saw Mary reading English.當(dāng)我到這兒時，我看到瑪麗在讀英語。
Many people were killed or injured when the police arrived at the Kunming railway station at night on March 1,2014. 2014年3月1日晚，當(dāng)警察到達(dá)昆明火車站時，已有許多傷亡。
3）從句中常用一般現(xiàn)在時替代一般將來時，用一般過去時替代過去將來時。
【典例】I will tell him the news when he comes here tomorrow.明天他來時，我將告訴他這則消息。
They would be excited when they knew their grades.當(dāng)他們知道他們的成績時，他們會很激動的。
2.when 譯為“一/剛……就”
1）when 相當(dāng)于as soon as /immediately/instantly/directly等詞的意思，引導(dǎo)時間狀語從句。
【典例】We will start when the monitor comes. 班長一來，我們就出發(fā)。
2） when用于固定結(jié)構(gòu)“hardly/scarcely…when…”.
此時when 可換作before. 注意：當(dāng)把hardly/scarcely放句首時，句子需部分倒裝。
【典例】I had hardly arrived home last night when it began to rain.
Hardly had I arrived home last night when it began to rain.昨晚我一到家，天就下雨了。

3.when 譯為“如果……”
when相當(dāng)于if,引導(dǎo)條件狀語從句。
【典例】Turn off the light when nobody is in the classroom.如果教室沒人了，把燈關(guān)上。

6.when譯為“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 作并列連詞，引導(dǎo)并列分句
when譯為“突然……或這時……”.可用在四種句式中，表示一個動作“正在發(fā)生”、“即將發(fā)生”、“剛剛完成”突然插入另一個動作。when 相當(dāng)于 and just time 或and just at that time.此用法也是高考的高頻考點(diǎn)。
1.was/were doing…when…正在做……這時/突然……
【典例】I was walking along the river when I heard a drowning boy crying for help.

三、when作從屬連詞，引導(dǎo)名詞性從句
when引導(dǎo)名詞性從句，在從句中作時間狀語，意為“什么時候”.從句常包括主語從句、賓語從句、表語從句和同位語從句。此時注意：從句要用陳述語氣。

英語幽默小故事
A Gentle Reminder
Having been married a long time, my husband sometimes needs a gentle reminder of a special occasion. On the morning of our 35th anniversary, we were sitting at the breakfast table when I hinted, “Honey, do you realize that we've been sitting in these same two seats for exactly 35 years?”
Putting down the newspaper, he looked straight at me and said, “So, you want to switch seats?”
委婉提醒
婚后已久，我丈夫往往在一個特別事情上需要委婉的提醒。在我們結(jié)婚35周年紀(jì)念的早上，我們正坐在早餐桌旁，我暗示道：“親愛的，你意識到我們在這兩個相同的座位上已坐了整整35年了嗎？”
他放下報(bào)紙，眼睛直直地望著我：“因此，你想交換座位嗎？”
