判断as做什么词性?

2作介词时:后接名词性成分组成介宾短语

4.作副词时后面跟形容词或者副词
5.引导定语从句时,做主语或者宾语
01as连词例句分析
as作为连词+完整句子 释义:当..时候 由于 因为 像......一样,就是说当as后面接 主谓宾或者主系表的时候是作为连词成分
🔺 As he grew older, he lost interest in everything, except gardening.
随着年纪越来越大,他对一切都失去了兴趣,除了园艺。(当...时候)
I watched her as she combed her hair.(当...时候)
· As he was waiting for the woman, he became very impatient.(当...时候)
· As he grew older, he lost interest in everything except gardening.(当...时候)
🔺 因为As he's been ill perhaps she;ll need some help.
她由于生病可能需要些帮助。
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。(因为)
02as作关系代词例句分析
什么时候作关系代词呢?当as位于句子主语 或者是系动词的表语或者谓语动词的宾语 这个时候就是作关系代词
as引导限制性定语从句:
(1)such + n. +as 例子:I don’t like such a man as tells lies.(主语)
(2)the same + n. + as 例子:I have the same book as you bought yesterday.(宾语)
注意:such ... that和such ... as之间的辨析?
such ... that引导【结果状语从句】
such ... as引导【定语从句】
实例:
(1)They talked in such simple English _____ children could understand it.
(2)They talked in such simple English _____ children could understand.
as引导非限制性定语从句:
(1)位置上:居首、居中、句末
(2)先行词上:as引导的非限制性定语从句,先行词通常是一个完整的句子。
(3)区别点:which也可以引导非限制性定语从句
情况一:as引导的非限制性定语从句位于居首
1. As I expected, he didn’t believe me.
2. As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlies all social interrelationships.
★分析:
此时as指代的是后面的整个句子,即as的先行词是可以出现在其后面的。
★区别:
which引导的非限制性定语从句,其先行词只能位于which之前,故which引导的非限制性定语从句不可以放在句首。
03as作为副词例句分as+adj/adv.
像…一样;那样...”。可以单独使用,但更多的是用在as...as结构中,其中第一个as是副词,其后可接形容词或副词,也可接其他成分,as前可有状语。第二个as可以是介词,也可以是连词 如何判断是副词 直接看as后面跟的成分
The nightingale were singing and the child sang as sweetly.
这孩子唱歌就像夜莺鸣叫一样甜美。
在as…as…,not as…as…结构中的第一个as是副词,表示“和/与…(不)一样”。
如:Jack is as tall as his father.
杰克和他的父亲一样高。
He doesn't speak English as/so fluently as
