二、复合句 1.主语从句:在句子中充当句子主语的从句叫主语从句。如: When we should start is still a question. 2.表语从句:在句子中作连系动词的表语的句子,它位于主句中的系动词之后。如: That is why he did not come to school yesterday. 3.宾语从句:在句子中作及物动词或介词的宾语。如: They believe that the computer will finally take the place of human beings. 4.同位语从句:在句子中作同位语的从句叫同位语从句。如: The news that our team won is exciting.
5.定语从句:在复合句中作定语用来修饰句子中某一名词或代词的从句叫定语从句。如: This is the missing boy(that/who/whom) we have been looking for these days. 6.状语从句:在复合句中作状语,其位置可以在主句前或主句后。 ①时间状语从句通常由when,as,while,after,before,since,as soon as, till(until),whenever等引导。 如:

并列句和复合句 一、并列句 并列句由两个或两个以上的独立分句并列在一起构成。其基本结构为:分句+并列连词+分句。 并列句有两个或两个以上的主谓结构。这些主谓结构之间的关系是并列的、对等的。从语法上讲,所谓“并列”、“对等”是指任何一个主谓结构都能独立地表达意思,谁也不从属于谁。尽管如此,这些主谓结构在意思或逻辑上有一定程度的内在联系。否则,它们就可能被分别写成简单句,而没有必要写在一起构成并列句了。在并列句中,要使两个或几个主谓结构(或者说分句)连接在一起,就要用并列连词。并列连词用来连接平行对等(即互不从属)的分句。 在并列句中,除了使用并列连词外,还可使用并列连词词组或连接副词来连接分句。有时甚至不用并列连词,只用逗号、分号、冒号等把分句隔开。 常用的并列连词有:and,but,or,for,so,neither,nor等;并列连词词组有:either...or,neither...nor,both...and,as well as,not only...but also等;连接副词有:besides,furthermore,moreover等。 1.表示联合关系 常用and,neither...nor,not only...but(also)等连词。如: There was a big storm after midnight and
the rain poured down. 后半夜来了一场暴风雨,大雨倾盆而下。 Pip is not only
a character;he also tells the story of Great Expectations. 皮普不仅是一个小说人物,他还讲述《远大前程》的故事。 I can neither write songs nor play the guitar. 我既不会创作歌曲也不会弹吉他。 Not only did he speak correctly,but he spoke easily. 他不仅讲得对,也讲得轻松。 2.表示选择关系 主要由连词or(或者;否则),either...or...(要么……要么……),neither...nor...(既不……也不……),otherwise(要不然)等连词连接,前后两个分句为选择关系。如:
