英文中数字的写法和汉语有所不同,想必大家都已经了解。但日常生活中难免还会连词是指把词、词组、分句和句子甚至段落连接起来的起连接作用的词或词组。连词的种类很多,主要有以下几类:
一、并列连词
1、表示对等关系的并列连词。使用该类并列连词时必须保持结构对等,词性统一,在句子中要使用对等成分,不可失之偏颇。常用的该类连词有:and,either...or,neither...nor,as well as,both...and,not only...but also。如:
This is an old clock that is not only very handsome but also accurate.
2、表示选择关系的并列连词。常用的该类连词有:or,or else,otherwise,rather than,either...or。如:
You should get the license right away,or you'll have to pay a fine.
3、表示转折和对比关系的并列连词。常用的该类连词有:but,while,whereas,yet,however,nevertheless,on the other hand,on the contrary。如:
She is a funny girl,yet you can't help liking her.
4、表示因果关系的并列连词。常用的该类连词有:so,for,therefore,hence,thus,consequently,accordingly。如:
It was raining heavily,so the sports meeting was postponed.
二、从属连词
1、引导时间状语的从属连词。该类连词除一些常用的外,还包括:as soon as,the moment(一……就……),the minute,the instant,once, immediately(一……就……),no sooner...than
(一……就……),hardly...when(刚……就……)。
如:
He told me the news immediately he got it.
2、引导地点状语的从属连词。该类连词有两个:where和wherever。如:
Where there is a life,there is a hope.
3、引导条件状语的从属连词。该类连词除
if,unless和if only(要是……就好了),还有:
provided(that),providing(that),supposing(that),
suppose,in case(that),as long as(只要),on condition that。如:
If only I had more money,I could buy some new clothes.
4、引导目的状语的从属连词。该类连词主要有:so that,that,in order that,lest,for fear that, in case(that)。例如:
She worried for fear that the child would be hurt.
5、引导原因状语的从属连词。该类连词主要有:as,because,since,in that, now that(既然),seeing that(鉴于)。例如:
Seeing that it is eight o'clock,we'll wait no longer.
6、引导比较状语的从属连词。该类连词主要有:as,as...as,less(more)... than,the more...the more。例如:
The more we can do for you,the happier we will be.
7、引导方式状语的从属连词。该类连词主要有:as,as if(好像),as though(好像)。例如:
Heat can flow from a hot body to a cooler body as if it were a fluid.
8、引导结果状语的从属连词。该类连词主要有:so...that,such...that,so(that)。例如:

9、引导让步状语的从属连词。该类连词主要有:though,although,even if,even though, while,as,whatever,however,whoever,no matter...(不管)。例如:

三、连接代词和连接副词
这类词用来引导名词性从句。连接代词有:that(不充当成分),which,what,who,whose等;连接副词有:when,where,how,why等。
四、关系代词和关系副词
这类词用来引导定语从句。关系代词包括:who,that,which,as,whose,whom等。关系副词包括:when,where,why,how等。关系代词和关系副词起着三重作用:其一,它们连接着主句和从句;其二,它们代表着主句的一个先行词(which和as还可以代表主句中的一个词组或整个句子);其三,它们又在从句中充当成分。
