在主语从句中,主句的谓语动词用单数吗

Question

如题所述

Answer 1

一般说来，短语或从句作主语，往往表示的是单数概念，谓语动词应该用单数形式。但是
what
引导的主语从句有时候后面是并列的表语，表示复数概念，谓语动词需要与复数主语保持一致，例如：
what
i
wanted
was
(a
few
days'
rest).
我最想要的就是能休息几天。【单数概念】
what
i
wanted
were
(a
few
days'
rest
and
some
big
meals).
我最想要的就是能休息几天并美美地吃上几顿。【复数概念】

Answer 2

需要具体问题具体分析，得分哪类的题型，如果主句表达的含义是复述，那么它的谓语用复数形式；反之用单数

Answer 3

1,
what
引导的主语从句作主语时，谓语的数由后面的表语或宾语确定。例如：
What
she
said
is
correct.
What
he
gave
me
are
five
English
books.
2,
其它词引导的名词性从句作主语时，谓语用单数。
例如：
Who
is
responsible
for
the
accidents
is
not
clear.
