‎ 2018届二轮复习 when的用法详解 一、when 用作疑问副词 用作疑问副词，引导特殊疑问句。例如：‎ When will you come to see me? 你什么时候要来看我?‎ When are they going to visit the Great Wall in China? 他们打算什么时候去游览中国长城?‎ 二、when 用作连接副词 用作连接副词，用来引导主语从句、宾语从句、表语从句、同位语从句及起名词作用的“ when ＋动词不定式”结构。例如：‎ When he will come is not known. 他何时来还不知道。（主语从句）‎ I don't know when he will come. 我不知道他何时来。（宾语从句）‎ What I know is only when he will come. 我所知道的就只是他何时来。（表语从句）‎ I have no idea when he will come. 我不知道他何时来。（同位语从句）‎ He doesn't know when to come. 他不知道该在何时来。‎ 三、when 用作关系副词 用作关系副词，当先行词是指时间，且在定语从句中作状语时，用when来引导定语从句，可引导限定性定语从句和非限定性定语从句。例如：‎ Do you still remember the days when we stayed together in America? 你还记得我们一起呆在美国的那些日子吗?‎ Do you still remember the days when we spent together in America? 你还记得我们一起在美国度过的那些日子吗?‎ The day will come soon when the Chinese astronauts will go to the moon.中国宇航员登上月球的那一天很快就要到来了。（分割性定语从句，先行词被主句谓语动词隔开，为了句子平衡）‎ It happened ten years ago, when I was a child.事情发生在十年前，当时我还是个小孩子。‎ We came back on Tuesday, since when we have been working in the repair shop.我们星期二回来，从那时起就一直在修配车间工作。‎ 四、when 用作从属连词 ‎1、用作从属连词，意为“当……的时候”，引导时间状语从句，可跟瞬间动词或延续性动词，可表时间点或时间段。例如：‎ They learned a lot from the peasants when they stayed in the village. （延续性动词，时间段）‎ 他们住在那个村子时，从农民那里学到了许多东西。‎ It was snowing when he arrived at the station. （瞬间动词，时间点）‎ 他到达车站时，天正下着雪。‎ ‎   注意：如果 when 引导的从句中的主语和主句中的主语一致，且从句中的谓语动词是“ be ＋分词”或从句主语是 it ，则 be 动词及其主语常可省略。例如：‎ When（he was）asked why he was late, he made no answer.当被问到他为什么迟到时，他避而不答。‎ I'll tell him about it when（it is）possible. 在可能的时候，我会把那件事告诉他的。‎ ‎2、用作从属连词，意为“倘若，如果”，表示条件。例如：‎ He will be likely to recover when he is operated on. 如果动手术，他有可能康复.‎ Turn off the switch when anything goes wrong with the machine. 如果机器发生故障，就把电源关上。‎ ‎3、用作从属连词，有“既然……(= since)”的含义。此时when从句说明主句的理由或是一种借故。例如:‎ ‎　　I can’t tell you anything when you won’t listen.既然你不想听，我就不告诉你了。‎ 五、when 用作并列连词 ‎1、用作并列连词，意为“在那时，届时”，位于句中，表示时间，这时主句中可以用过去进行时，过去完成时或“ was/were about to do sth.”结构。例如：‎ Last night I was about to go to bed when the phone rang. 昨天晚上我正要上床睡觉时，电话铃响了。‎ I was cooking in the kitchen when someone knocked at the door. 我正在厨房做饭，这时有人敲门。‎ He had just finished the book when supper was served. 我刚刚读完这本书，这时晚饭就端上来了。‎ ‎2、用作并列连词，意为“一……就……”，位于句中，紧跟“意想不到”的第二个动作。可以用从属连词as soon as替换。例如：‎ I had hardly opened the door when he came in.我刚一开门，他就进来了。‎ ‎= I had scarcely opened the door when he came in. 我刚一开门，他就进来了。‎ ‎= Hardly/Scarcely had I opened the door when he came in.我刚一开门，他就进来了。(否定副词放在句首，从句用半倒装句式)‎ ‎=As soon as I opened the door, he came in.我刚一开门，他就进来了。‎ 六、when 用作代词 when 作为代词常常位于介词之后，意为“那时，什么时候”。例如：‎ Since when have you been studying Japanese? 你是从何时起一直学习日语的?‎ 歌词Because you loved me For all those times you stood by me For all the truth that you made me see For all the joy you brought to my life For all the wrong that you made right For every dream you made come true For all the love I found in you I'll be forever thankful baby You're the one who held me up Never let me fall You're the one who saw me through through it all You were my strength when I was weak You were my voice when I couldn't speak You were my eyes when I couldn't see You saw the best there was in me Lifted me up when I couldn't reach You gave me faith 'cause you believed I'm everything I am Because you loved me Ooh, baby You gave me wings and made me fly You touched my hand, I could touch the sky I lost my faith, you gave it back to me You said no star was out of reach You stood by me and I stood tall I had your love, I had it all I'm grateful for each day you gave me Maybe I don't know that much But I know this much is true I was blessed because I was loved by you You were my strength when I was weak You were my voice when I couldn't speak You were my eyes when I couldn't see You saw the best there was in me Lifted me up when I couldn't reach You gave me faith 'cause you believed I'm everything I am Because you loved me You were always there for me The tender wind that carried me A light in the dark shining your love into my life You've been my inspiration Through the lies you were the truth My world is a better place because of you You were my strength when I was weak You were my voice when I couldn't speak You were my eyes when I couldn't see You saw the best there was in me Lifted me up when I couldn't reach You gave me faith 'cause you believed I'm everything I am Because you loved me You were my strength when I was weak You were my voice when I couldn't speak ‎(My voice.)‎ You were my eyes when I couldn't see You saw the best there was in me Lifted me up when I couldn't reach You gave me faith 'cause you believed I'm everything I am Because you loved me I'm everything I am Because you loved me ‎【歌词when从句解析】‎ ‎1.
