Beijing is the most beautiful place ____ people all over the world want visit.

在定语从句中,关系代词that和which指物时,一般没有区别,但下列几种情况中不能互换：
1 只能用that的情况：
a) 先行词为all,everything,nothing,anything,little等不定代词时（something后也可用which）：
Is there anything (that) I can do for you in town?
That’s all (that) I know.
b) 先行词被序数词所修饰时：
The first thing (that) we should do is to work out a plan.
c) 先行词被形容词最高级所修饰时：
This is one of the most exciting football games (that) I have ever seen.
The nanjing yangtse river bridge is the longest bridge (that) they have ever seen.
d) 现行词 被only,very,no,any,same,little,one of等词所修饰时：
This is the only thing (that) we can do now.
He gave me the same pen (that) he borrowed from me.
Do you have any books that were written by Lu Xun?
This is the very book (that) I want to read.
e) 当先行词中既有人又有物时：
The man and the car (that) you want to see are all here.你相见的人和车都在这里.
f) that可指人,which则不能：
Who is the man that is reading the newspaper over there?
g) 在“the time when”等结构和某些时间状语中,when常被that代替,而且that往往省略：
I may leave here any time I want to.
During the time I was there I visited him twice.
h) way后面可根由that引导的定语从句,但that一般都省略：
That was the way she looked after us.
在这里,place被最高级修饰,所以只能选that,不可以用which.
