All 的主要用法
一、形容词 all 作“所有的”、“一切”、“全”讲

二、all 作名词或代词用,作“全部”、“全体”、“一切”讲
- All of us are waiting to get online. 我们全体都等着上网。(作代词)。
- You have to note down all that is important. 你得把重要的都记下来。(作名词。本句还可用 what 代替 all that 引出的从句)。
- The workers did all (that) they could to increase the production of steel. 工人们尽了他们最大努力来提高钢产量。(作名词。直译为:工人们为了增加钢产量而做了他们能做的一切。也可用 what 代替 all that。)
三、注意 all 作主语的同位语时在句中的词序
- We are all here. 我们全在这儿。
- They are all network engineers. 他们都是网络工程师。
- They all made a quantity of high temperature tests yesterday. 他们昨天都做了一些高温试验。

四、all 作副词用,在句中作状语,表示“全”、“尽”之意

- I think I am all wrong. 我想我全错了。
五、“all(或 every)+否定式谓语+…”构成部分否定

- All glass is not transparent. 并非所有的玻璃都是透明的。(= Not all glass is, transparent.)
- I do not know all (或 everyone) of them. 我并不是认识他们中的每个人。
注:在“all…+肯定式谓语+含有否定意义的单词……”的结构中,all 仍被全部否定。这时它的否定意义不是通过谓语,而是通过句子其它成份中含有否定意义的单词表达出来的。例如:
1)All atoms are invisible to the naked eye. 一切原子都是肉眼看不见的。 2)We all dislike going to the teahouse. 我们都不喜欢去茶馆。 3)All her ideas came to nothing. 她的一切想法都没有实现。

注:不难看出,at all 只用于否定句、疑问句和条件句中,以加强语气。
