Answer 1

1）
当先行词是：all

,
anything
,
everything
,
nothing或被它们修饰时。例如：
Is
there
anything
that
I
can
do
for
you
?
有什么可以为你做的吗？
All
that
can
be
done
must
be
done
.
凡是能做的都必须做。
2）当先行词被形容词的最高级或序数词修饰时。例如：
That
is
one
of
the
most
interesting
books
that
are
sold
in
the
bookshop
.

food
.

3）当先行词有：the

,
the
last
等修饰时。例如：

necklace
is
not
the
only
thing
that's
missing
.
我的项链不仅是丢掉的东西。
4）当主句以who或which开头时，定语从句中引导词用that

who
。以避免重复。例如：
Who
is
the
girl
that
is
wearing
a
red
coat
?
正穿一件红色外套的女孩子是谁？
5）当先行词既有人又有物时，用that
