Question

一到英语题：Is this book _____ you borrowed from the school library? A the one B that

Answer 1

1.
答案：A
the
one.
2.
解释：
1）这样的题目，需要把它变成陈述句就很简单了：
A：This
book
is
the
one
(that)
you
borrowed
from
the
school
library.
B：This
book
is
that
you
borrowed
from
the
school
library.
2）如果选B
that
理解成表语从句的话，则表语从句中borrowed后面缺少宾语，所以必须用what来引导，因为that引导的表语从句时，that不能在从句中充当任何成分，只起引导作用。
理解成定语从句的话，则主句This
book
is不完整，它缺少表语（先行词），也就是说定语从句that
you
borrowed
from
the
school
library所修饰的对象都没有。
3）选A
the
one
=
the
book，主句This
book
is
the
one完整。
而定语从句you
borrowed
from
the
school
library修饰先行词the
one，且关系代词代替the
one，在定语从句中充当borrowed的宾语，所以关系代词可以省略。
