『壹』 英语语法：as的用法
as可用作连词，引导比较、时间、原因及方式等四种状语从句，应注意的是，引导的比较状语从句往往有省略；引导的时间状语从句一般用一般现在时而不用一般将来时；引导原因状语从句时与“Because”和“since”引导的从句比较起起来语气最弱。
as作介词，意思时“作为”，“以……身份”。例如：He came to China as a tourist five years ago.
而表示像…一样时，like通常作介词用，而介词后面通常接名词，代名词和动名词。
as in Australia“和在澳大利亚一样”。

『陆』 英语语法并列句讲解
并列句概念
两个或两个以上的简单句用并列连词连在一起构成的句子,叫做并列句,其基本结构是“简单句+并列连词+简单句”。并列连词有：and,
but,
or,
so等.并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。
如:
I
like
action
movies
but
don't
like
thrillers.
Hurry
up
or
you'll
be
late.
(快点，否则你要迟到了。)
and,
or和but都是连词，在句中连接两个或两个以上的并列成分。可连接两个词，两个短语，两个分句，但所连接的两个成分必须一致，绝不能一个是词，一个是句子。如:
I
like
red
and
orange.
He
isn't
my
brother
or
my
friend.
I
like
playing
football
and
swimming.
and
的意思是“和”，表示前后两个成分的并列或对称关系；or的意思是“或者”、“否则”、
“要不然”，表示两个成分并列或选择关系；but
的意思是“但是”，表示两个成分之间的转折关系。
并列句中：1.表并列关系的
由and,both...and,as
well
as,not
only...but
(also),neither...nor等组成。
She
not
only
sings
but
also
dance.
2.表转折关系的
与but,however(然而），while(然而），still,yet等连用。
The
film
is
not
perfect,still,it's
good.
3.表选择关系的
由or,either...or...,not...but...,or
else(否则）连接
Take
the
chance,or
else
you
will
regret(后悔)
it.
4.表因果关系的
与for,so/so
that,therefore(因此),because等连用。
I'd
better
take
an
umbrella,for
it
is
going

『柒』 英语语法并列句讲解
并列复合句是由两个或两个以上并列而又独立的简单句构成。两个简单句常由并版列连接词连在一起；但权有时不用连接词,只在两个简单句之间用一逗号或分号。 常见的并列句： (1)用来连接两个并列概念的连接词有and , not only…but also…, neither…nor…等,and所连接的前后分句往往表示先后关系、递进关系。前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。 (2)表示在两者之间选择一个,常用的连接词有or,otherwise,or else,either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。 (3)表明两个概念彼此有矛盾、相反或者转折,常用的连接词有but,yet,still ,however等,前后分句时态一致。 (4)说明原因,用连接词for ,前后分句时态一致。 (5)表示结果,用连接词so,前后分句时态一致。

『拾』 英语语法：关系代词、连接代词的性质
英语语法：关系代词、连接代词的性质 浏览次数：58次悬赏分：50 | 离问题结束还有 9 天 0 小时 | 提问者：kissmorning | 检举
关系代词、关系副词、连接代词等的词性究竟是什么？比如关系代词，我在语法书里的代词一章下看到，在连词一章也看到，成为从属连词，请问究竟算什么？？
答：这个问题很好。
我们一般说连词conj. 有两类：并列连词和从属连词。and, but, or等是并列连词，它们用来并列两个简单句构成一个并列句。
顾名思义，从属连词就是连接从句的连词了。而实际上，连接（引导）从句的词，不仅有从属连词，还有引导定语从句的关系词（关系代词和关系副词），引导名词性从句的连接词（有连接连词that, whether,有连接代词what, which, who, whom, whose和连接副词when, where, why, how...)和引导状语从句的连词。
连词(conj.)只起到连接句子的作用，它不作句子成分。所以从属连词其实主要就是引导状语从句的连词：when,before, after, as, .... where, why,because ....
你的语法书在词类上，有点乱。关系代词、关系副词的词类还是代词和副词，在从句中是作成分的。连接代词也是代词，在从句中也是作句子成分的。只有引导名词性从句的连词that和whether 在从句中不作成分。可以说，这两个词在这里是conj.
