2021中考英语考前错题本 （N字母篇）
night
［误］ i came home very late yesterday night.
［正］ i came home very late last night.
［析］ "昨晚"一般要讲last night，而不应参照"昨天上午、下午、傍晚"的说法yesterday morning等套用。
no none
no是个限定词，它可以用在可数名词单 复数或不可数名词前，如： no news is good news. 但如果名词前有另一限定词时则不能用no，而要用none of，如none of the students was here.
no not
要使句子具有部分否定的意思，我们用not，如： i can see you tomorrow, but not sunday. 如果是全部否定则用no，如sorry, there is no time to talk.
no one none
no one与nobody一样不能接of结构，如： no one wished me good luck. 而要用of结构时要用none, 如： none of my friends wished me good luck.
nor
［误］ i never saw the painting before, or did i hear of it.
［正］ i never saw the painting before, not did i hear of it.
［析］ 注意在表达"既不……也不……"时不要用or作连词，而要用nor，并且要用倒装语序。
not
［误］ the students went to the park, but no the teachers.
［正］ the students went to the park, but not the teachers.
［析］ 要使一个句子或一个句子的某一部分为否定时我们要用not, 而不用no.
［误］ there is no my letter today.
［正］ there is no letter for me today.
［析］ no是一个限定词，用在名词前时，要注意这个名词前应没有冠词、物主代词或指示代词。
［误］ he not only was a writer but also an actor.
［正］ he was not only a writer but also an actor.
［析］ 在这一句型中not only之后的词与but also之后的词类必须一致，否则应为错句。如果这一结构用在主语位置，则谓语动词要与but also后面的主语保持一致，如： not only you but also i am wrong.
nothing
［误］ nothing but books were sold here.
［正］ nothing but books was sold here.
［析］ 要注意真正的主语是nothing而不是books，所以这一结构在学生的使用中经常出错。
［误］ i have nothing to do but to cry.
［正］ i have nothing to do but cry.
［析］ 在这一结构中but后面要用省to的不定式。
number
［误］ a number of news can be heard on tv today.
［正］ a lot of news can be heard on tv today.
［析］ a number of后接可数名词复数。
［误］ the number of students are ten thousand.
［正］ the number of students is ten thousand.
［析］ a number of 其意为"大量的"，而the number of…是"某某的数量"。即the number of students意为"学生人数"，所以要用单数形式的谓语动词。
