28.Mary has never been to Tibet,but that’s the only place _____.A.what she most wants to visit B.where she most wants to visit C.which she wants to visit most D.that she wants to visit most定语从句中,什么时候用where when what 作为引导
答案：D
where,when均由“介词+关系代词which”变化而成.
where：用以修饰表地方的名词,如国家.城市、车站、商店等）
例：This is the city where I met mary.
=This is the city in which I met mary.
when
when：用以修饰表时间的名词,如（年,月,星期五等等）
例：He came on Friday,when it was rainning hard.
=He came on Friday,on which it was rainning hard.
what：what可视为the thing/things which,通常译成“所.的东西”
what使用要注意的原则:
1.前面不可有先行词（名词）；
2.将what视为the thing/things which;
3.which在所引导的定语从句中可做主语、宾语或在be动词后作表语.
例：a.I am interested in what he is dong.
b.What bothers me is that i have no time.
=The thing which bothers me is that i have no time.
that:
1.that仅能出现在限制性定语从句中,即前面不准有逗号.
2.that之前不可有介词.
3.只能使用that的情况：序数词后、最高级之后、all之后、the only+名词之后等
在定语从句中，有the only 修饰的引导词只能用that.
