六、all, both, each 等用作同位语
若用作主语同位语,主语可以是名词或代词;若用作宾语等其他成分的同位语,则宾语等成分必须是人称代词,而不能是名词:
We have all read it. 我们都读过他。(all 修饰的主语是代词)
The villages have all been destroyed. 村庄都被毁了。(all 修饰的主语是名词)
They told us all to wait there. 他叫我们都在那儿等。(all 修饰的宾语是代词)
但不能说:They told the men all to wait there. (all 修饰的宾语是名词不是代词)
七、so little 与 such little的区别
用so little还是such little取决于little的意思:若表示数量方面的“少”,则用so little;若表示形状体积的“小”,则用such little:
He has so little time for reading. 他读书的时间少得可怜。
I’ve never seen such little boxes. 我从未见过那样小的盒子。
八、some 与 any的用法区别
一般说来,some 用于肯定句中,any 用于否定句和疑问句中。但是,在表示请求、邀请或征求意见的句子中,通常要用 some 而不用any:
Would you like some cake? 吃点蛋糕吗?
Why not buy some bread? 为什么不买些面包呢?
Shall I get some chalk for you? 要我帮你拿些粉笔来吗?
【说明】any 有时也用于肯定句中,此时表示“任何”:
Any colour will do. 任何颜色都行。
Come any day you like. 随便哪天来都可以。
九、many 与 much的用法区别
两者都表示“许多”,但 many 修饰或代替可数名词(复数),与 few(少数)相对;而 much 用来修饰或代替不可数名词(单数),与little(少量)相对。在口语中两者主要用于非肯定句中:
Did you see many people there? 你在那儿看见许多人了吗?
We don’t have much time. 我们没有许多时间。
在肯定句中,一般用 a lot of, lots of, plenty of 等代之。但在正式文体中有时也用于肯定句中;另外,若用作主语或主语的定语,或其前有 how, too, as, so, a good, a great 等修饰,也可用于肯定句中:
Many of us left early. 我们有许多人离开得很早。
Much work has been done. 许多工作都已经做了。
You’ve given me too much. 你已给我太多了。
Take as many (much) as you want. 你要多少拿多少。
I asked her a great many questions. 我问了她许多问题。
十、few, a few 与 little, a little的用法区别
1. few和a few 后接可数名词的复数形式。few 表示数量很少或几乎没有,强调“少”,含有否定意义;a few 表示数量虽然少但毕竟还有,强调“有”,含有肯定意义:
It is very difficult, and few people understand it. 它很难,没有几个人能懂。
It is very difficult, but a few people understand it. 他虽难,但是有些人懂。
2. little 和 a little 之后接不可数名词,其区别跟 few 和 a few 之间的区别相似:
Unfortunately, I had little money on me. 很不巧,我身上没带什么钱。
Fortunately, I had a little money on me. 幸好我身上带着一点钱。
