㈠ 求解一道英语语法题，关于as的用法
我认为 原句来=She is tall while he is short,and he is fat while she is thin.But they are both happy when they are old
所填as这里仍然是自连词 引导的仍然是 状语从句 ，不过 不是 比较状语从句 前两个 可以看做方式状语 后一个 可以看做 时间状语
㈡ 英语句子语法分析as的用法
1、as是做关系代词。指代是的：前面整个句子（多送件人可以监控的情况）专
2、是的，上面说了，属代整个句子做主语。
完整应该是有is的，但由于主句的谓语也是is，所以省略掉了。
不明白，请追问
若有帮助，请采纳
㈢ 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”。
as……as
AS +adj(原级)+AS
AS +adv(原级)+AS
as soon as 一……就
as soon as possible 尽可能快地
as early as possible 尽可能早的
as carefully as you can 尽可能认真地
as careful as you can 尽可能认真的
1。as是连词，表示“随着”的意义。lives是life的复数，意义是“生活”。<BR>
2。as是连词，表示“因为，由于”的意义。wanting是现在分词，表示主动意义，wanting to buy cars=who want to buy cars。
As的用法小结
as可以作连词、介词及关系代词和副词。现将其用法小结如下:
（一）、 as作连词的用法:
1.作“在-------期间，当----的时候”引导时间状语从句.注意与when、 while的用法区别。
①下列情形时,只用as, 而不用when或while。
1)用于表示同一个人的两种动作交替进行,指一边----一边. 如:
The girl sings as she goes to school.
He looked behind occasionally as he went forward in the forest.
2)表示两个同步发生的动作或行?意思是随着-----的发展.如:
As time went on / by, she became more and more beautiful .
As children get older, they become more and more interested in everything.
3)表示两个短暂行为或事情几乎同时发生.如:I watched her as she read the book.
I thought of it just as you opened your mouth.
Just as the flying worm hit her face, she gave a loud cry.
4)接在名词后面表示某一个年龄段时.如:
As a young man, he was active in sports.
②when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。如:When I was at college, I could speak several foreign languages. When the clock struck twelve, I had slept for 2hours.
③ while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。如:Work while you work. Play while you play.
2. As =Since 作"既然"、"由于"解,引导原因状语从句,常用来表示已为人们所知或显而易见的原因或理由。如: As he’s been ill for ages, I will help him.
As / Since you're not feeling well, you may stay at home.
As he wasn't ready , we went without him.
3. As =in the way that作"像"、"按照……的方式"解,引导方式状语从句。如:
Do as I told you.
Remember, you must do everything as I do.
4. 用于as--- as或not / so/ as ---- as中,前一个as是副词,后一个as是连词,引导比较状语从句。如:They helped the old as much as possible.
I don't speak English so/ as well as she does.
5. 表示虽然,尽管 等,引导让步状语从句,常用倒装语序,模式为:
adj. /adv. / n.+as +主语+谓语+主句。如: Young as he is, he knows much.
Tired as they were, they walked on.
6. 表示也------一样。 She is a doctor, as was her husband.
（二）、 as作关系代词,引导定语从句,表示正如,这一点.如:
He is very careful, as we all know.
As is well-known, Taiwan belongs to China.
另外,当先行词被the same, such等词修饰时,常用as来引导定语从句。如:

I was reading the same book as he bought yesterday.
（三）、as作介词的用法.
1.表示好像。如:He dressed as a policeman.
2. 表示作为当作。如：I found a job as a guide.
3. 当某人是某身份时。如：As a child , she was sent to abroad.
4. as引导的介词短语大多用作状语,as译为"作为";少数情况可引起宾语补足语。如:
As a Party member, I'll take the lead in everything. (状语)
She works as a model. (状语)
She has me as one of her best friends.(引起宾语补足语)
（四）、作副词的用法 1 表示与------等同。如：This dress is twice as expensive as that one. 2 像，如等。如：As before, he remained unmoved.
总之，通过以上的分析，我们对as的词性和用法有了比较全面的理解和把握，才能在实际的运用中做到心中有数，应付裕如。
㈣ 英语语法： as....as....的具体用法是如何 as是作为介词理解还是什么两个as中间可以放什么内容整个
as……
用于比较两个事物，中间可以放形容词，形容词性词组，副词，表达“……和……一样……”的意思
He is as tall as me 他和我一样高
He runs as fast as me.他跑地跟我一样快
你列举的screwed up 算是一个过去分词构成的形容词性词组，意为：心烦意乱的
例：I was totally screwed up with him 我被他弄的心烦意乱
as作为介词有以下意思
as a stutent “作为”一个学生
he works as a doctor there 他“以”医生的身份在那工作——他在那当医生
We treat him as our brother.我们把他”当做兄弟看待“
同时as也可以做连词，用作引导时间、原因状语（从句），具体意思根据不同句子而不同

Today, as usual, he was wearing a three-piece suit.今天他像往常一样穿着一套三件套西装。
As you can see, we're still working.如你看到的，我们仍在工作。
Enjoy the first hour of the day. This is important as it
sets the mood for the rest of the day.享受一天中的第一个小时。这很重要，因为这第一个小时决定当天其余时间的情绪。
㈤ 英语语法：as much as 的用法解析
as much a part of our lives as are our meals,
第一个as是副词修饰形容词much
as much是形容词修饰名词a part
本句as much a part是表语of our lives是定语 。我们生活中很重要的一部分
第二专个as是关系代词 引导定属语从句 修饰much a part of our lives
as在从句中作表语 are是从句中的系动词 our meals是从句中的主语
从句是倒装句
意思是 与一日三餐同等重要的生活中的一部分
㈥ 英语语法问题，同位语、插入语、as的用法
同位语从句的前复面一定有制个跟同位语意思相同的词，比如随便一个句子：The question that how to do housework should be discussed. 怎么样做家务应该讨论一下。that 后的how to do housework就跟question是一个内容，用来解释question的，所以是同位语。插入语是可以去掉的一部分，去掉后不会影响句子的大致意思。如：Who do you think did this?你认为这是谁做的？ do you think 就是插入语。 常用的插入语还有as it were等。呵
