5.珠海如此美丽以至于很多游客来这里度假。
Zhuhai is________ a beautiful city________ many visitorscome here for holidays.suchthat 连词主要分为两大类:并列连词和从属连词。并列连词用
来连接平行的词、短语或句子;从属连词是用来引导从句的词。
并列连词按照其在句中的作用可分为表示并列关系、转折关系、
选择关系和因果关系的连词。表示并列关系的并列连词 表示并列关系的常见连词有:and (和;又;而且), as well as
( 也 ; 和 ), both...and...( 既 ……又……), not only...but also...( 不
仅……而且……), neither...nor... (既不……也不……)。如:Tom and Lily like drawing.汤姆和莉莉都喜欢画画。Lin Ping as well as his classmates likes watching TV.林平和他的同班同学都喜欢看电视。Neither my parents nor my sister has been to Guangzhou. 我父母和我妹妹都没去过广州。注意:(1)在并列结构中表示“和”的意思时,and 用于肯定句,or 用于否定句。如:There is no air or water on the moon.
月球上没有空气和水。(2)当含有两个否定词的句子实际被看作是肯定结构,要用and。如:There is no air and no water on the moon.
月球上没有空气和水。表示转折关系的并列连词他尽力了,但还是失败了。注意: (1)however 意为“然而,不过”,可放在句首、句中或句
末,不能像 but 那样直接连接两个句子,常用逗号与句子其他
部分隔开。如:(×)We all tried our best, however we lost the game.
(√)We all tried our best.However, we lost the game.
(√)We all tried our best, but we lost the game.我们都已尽了最大的努力,不过我们还是输了。(2)not...but...意为“不是……而是……”。not 和 but 后面的词性要一致。如:They were not the bones of an animal, but (the bones) of ahuman being.它们不是动物的遗骸,而是人的遗骸。表示选择关系的并列连词 表示选择关系的常见连词有:or (或者;否则), either...or...(或
者……或者……/不是……就是……)等。either...or...连接多个主
语时,谓语动词的单复数与 or 后面的主语保持一致。如:Either he or I am to blame.不是他就是我该受责备。
Would you like tea or coffee?你要茶还是咖啡?When you are learning English, use it, or you'll lose it.
学英语的时候要应用,否则你就会忘记。表示因果关系的并列连词 1.for 表示“因为”时,用来补充说明或表示推测性的理
由,不能置于两个并列分句的句首,只能放在两个分句的中间。
如:It must have rained last night, for the ground is wet.
昨晚一定下雨了,因为地面是湿的。2.so 表示“因此,所以”时,不能与 because 连用。如:He worked hard, so he passed the exam.=Because he worked hard, he passed the exam.
他努力学习,所以通过了考试。从属连词从属连词用来引导状语从句、宾语从句、主语从句或表语从句。可用于引导宾语从句,常省略。如:续表 when (当……时),
while (当……时), as
(当……时;一边……
一边……), before
(在……之前), after
(在……之后), until
(直到……), since (自
从……), ever since
(从……以来), as soon
as (一……就……),
whenever (无论什么时
候) 可用于引导时间状语从句。如:
When the UFO landed, I was wal-king in
the street.
=The UFO landed while I was walking in
the street.当飞碟着陆的时候,我正在街
上散步。
She didn't go to sleep until she fi-nished
her homework.她直到做完了作业才去睡
觉。续表注意:because, for, since, as 的区别: (1)because 表示原因和理由,强调直接原因和因果关系,它
所引导的从句通常放在主句之后。常用来回答 why 引导的疑问
句。如:—Why didn't you go to the cinema?
你为什么没有去看电影?—Because my mother was ill, and I have to stay at home andlook after her.因为我妈妈病了,我得在家照顾她。(2)for表示间接的原因和理由,或对主句中事实的解释,for 引导的从句不放在句首。如:Miss Gao can't be in the office, for the door is locked.高老师不可能在办公室,因为门是锁着的。 (3)since 表示原因时语气比 because 弱,但比 as 强。它一般
不表示根本原因或直接原因,而是一种已知的、显然的理由。
作“既然”讲时,常放在句首。如:Since everybody is here, let's begin our meeting.
既然大家都在,我们开始开会吧! (4)as 表示原因时意义最弱,它所阐述的原因只是附带说明。
多置于句首,只说明一般的因果关系,可译为“鉴于”。如:As you were out, I left a message.
你不在,所以我留了一张字条儿。()1.(2014 年广东)Ben was busy taking a training class,________ we had to wait for him for half an hour.A.so
