(一)both和neither

这两个词都表示两者之间的关系,只是both表示“两者都...”,是肯定表达,而neither表示“两者都不...”,是否定表达。当both引导的成分作主语时,其谓语要用复数;当neither引导的成分作主语时,其谓语动词要采用单数。

如: Both of them are students.

Neither of them is a student.

注意:1.neither...nor...

当neither和nor同时搭配使用时,表示“既不...,也不...”。其引导的成分作主语时,谓语动词的单复数用法要采用就近原则。

如:Neither he nor we are going to the party.

Neither we nor he is going to the party.

2.both...not...

当both与not同时使用时,表示的是部分否定,即“不都...”。

如:Both of us are not teachers.

该句意思为:我们俩不都是老师。

(二)all和none

这两个词都用在三者及以上之间的关系,all表示“全都...”,是肯定表达,而none表示“全都不...”,是否定表达。当all和none都修饰可数名词时,如果all引导的成分作主语时,其谓语要用复数;如果none引导的成分作主语时,其谓语动词大多要采用单数,复数也可以。

如:All of the students are from France.

None of the students is/are from France.

注意:1、all...not...

当all与not连用时,表达的是部分否定,即“不都...”。如:

All of the teachers are not from China.

该句话的意思是:不是所有的老师都来自中国。

2、no one、nobody、nothing、none

no one / nobody常用来指人,作主语时,谓语动词要用单数形式;nothing常用来指物,作主语时,谓语动词也要用单数形式;none可指人也可指物,作主语时,如和of 连用,指不可数名词时,谓语动词要用单数形式;指可数名词时,谓语动词用单、复数均可。

No one likes the cake.

Nobody is qualified for the new job.

Nothing has changed in the past five years.

None of us is/are willing to work at night.

(三)either

该词表示两者选其一,即“或者...,或者...;要么...,要么...”。当引导主语成分时,其谓语动词的单复数采用就近原则。如:

Either you or I am going to attend the meeting.

Either I or you are going to attend the meeting.

注意:either也可以用在of结构中,此时如果它引导的成分作主语,其谓语动词要用单数。如:

Either of the players is going to take part in the sports meeting.
