Question

( ) my sister who has looked after me since my mother died. A it B it's C it was D that is

b or d, why?

Answer 1

b.
这是
强调句型。其基本结构为
It's
+
被强调部分
+
who/
that+
其它成分。可以强调除了谓语意外的所有成分。如:It's
in
the
classroom
that
we'll
have
the
meeting.
It's
tomorrow
that
we'll
have
the
meeting.
It's
we
that/
who
will
have
the
meeting
tomorrow.
注意最后一个例句中，被强调的是主语，所以用了WE，
而没有用US。
