up in the dictionary.如果在歌曲里有生词，我就查字典。,这是一个含有条件状语从句的主从复合句。主句中look up表示“(在词典、书籍中)查找”。,按照英语习惯用法，“查字典”为look up the words in the dictionary，不说look up the dictionary。另外，look up是“动副”结构的及物的短语动词，名词作宾语置于副词前后皆可，代词作宾语要置于副词之前。,If you dont know the meaning of a word，look it up in a good dictionary,如果你不知道一个词的意义，就去查一本好词典。,Will you look up a train for me in the timetable?,你可不可以帮我在行车时刻表中查找一个列车车次?,11.As you go to your home by the ocean may you never forget those sweet hours that we spent in the Red River Valley and the love we exchanged mid the flowers当你通过海洋到你家时，祝你永远不会忘记我们一起在红河谷度过的那些甜蜜时光以及我们一起在花丛中交换的爱情。,这是一个含有时间状语从句的主从复合句，主句中又含有两个定语从句。hours和love既在主句中作forget的并列宾语，又分别是其后定语从句所修饰的先行词。在前一个定语从句中，关系代词that既引导定语从句，又在从句中作spent的宾语；在第二个定语从句的主语we前，省略了既引导定语从句，又在从句中作exchanged宾语的关系代词that或which。主句中may用倒装语序表示祝愿。例如：,May you succeed!祝你成功!,May you be happy!祝你幸福!,May God bless you!愿上帝保佑你!,as用作连接词表示时间关系，用来引导时间状语从句，意思也是“当的时候”，往往可与when或while通用，但它着重指主句和从句中的动作或事情相并发生。例如：,I saw him as he was getting off the bus当他下公共汽车时，我看见了他。,As he walked on，he felt himself getting more and more tired.他继续往前走的时候，感到越来越疲乏。,As the day went on，the weather got worse随着时间的推移，天气变得更糟。,I was coming in as he was going out.我进来时他正出去。,My pen trembles as I write it.我一边写，笔一边颤抖。,Helen heard the story as she washed.海伦洗衣服的时候听到这个故事。,As I left the house I remembered the key.当我们离开房间的时候，我想起了钥匙。,【词语辨析】,1.spend，cost，take，pay表“花费”,(1)spend的主语必须是“人”，宾语可以是钱、精力、时间等 如：,He spends much money on books 他平时将很多钱用在买书上。,He spent a lot of money（in）buying a new
