no,not
这两个词在词义和使用场合上都有所不同。
No可以作副词,也可以作名词和形容词;not只能用作副词。现将它们各种用法分述如下,以便比较:
作副词时,no有下列两种用法:
(一)作为yes的反义词,用在回答问题的场合,表示“不”的意思。例:
No,I won't go to the casino.
不,我不去赌场。
(二)用在比较级之前,表示“并不”之意。例:
The weather today is no better than it was yesterday.
今天的天气并不比昨天好。
用作形容词时,no表示not any的意味。例:
There is no(=not any)time to lose.
时不可失。
注:当no用作形容词时,可直接放在名词之前,如果名词的前面有a、any、much、many、enough等词,就要改用not,不用no,因为not是副词,只有副词才有资格修饰a、any、much、many、enough等词。因此,我们说:
I have no money.或I have not any money.
作名词时,no表示“否定”的意思。例:
Two noes make a yes.
否定的否定就是肯定。
Not可用于
(一)修饰动词:
I do not know any of them.
这些人我一个都不认识。
(二)修饰形容词:
It's not cold today.
今天天气不冷。
(三)修饰不定冠词:
Three decades ago not a year passed without a number of people falling victims to hunger here.
三十年前,这里每年都有不少人死于饥荒。
(四)修饰副词:
Not seldom did I go to Victoria Park while I stayed in Causeway Bay.
我住在铜锣湾期间常到维多利亚公园去。
(五)修饰连词:
They are working hard not because they want to make money but because they know what they are working for.
他们在努力工作其原因并非是为了赚钱,而是在于他们知道为何而工作。
请注意下面no和not的区别:
Mr.Chen is no fool.
陈先生决不是傻瓜。
Mr.Chen is not a fool.
陈先生不是傻瓜。
He is no good at tennis.
他的网球打得很不好。
He is not good at tennis.
他的网球打得不好。
I have no more than ten dollars.
我只有十元钱。
I have not more than ten dollars.
我有不超过十元钱。
no=not any
There is not any one.=there is no one.
