Answer 2

a
number
of与the
number
of，二者的区别涉及到主谓一致的问题，它们修饰名词作主语时，谓语的数是不一样的。
①number
of
+名词复数=a
lot
of
=los
of+名词复数
②a
number
of…意思是“一些，若干”(=
some)，后接可数名词复数或代词，谓语动词用复数形式。
还可以加入形容词表示数量大或小等(例如：a
large/small
number
of…许多/少数……)。
a
number
of
students
of
our
school
have
read
that
magazine.我们学校有很多学生都看过那本杂志。
③the
number
of…意思是“……的数字/数目”，介词of同其后名词构成介词短语，修饰the
number.当它作主语时，谓语动词用单数。
例如：
many
people
took
part
in
10,000-metre
race,
but
only
a
number
of
them
kept
on
running
to
the
end.
许多人参加了10000米跑，但只有一些人坚持跑到底。
