2.当先行词被序数词修饰
(1) The first place that they visited in London was the Big Ben.

Answer 2

用that 这只能说是语法书里的概念了 ： 当先行词有the very，the only ,the same ,any,few,little,no,all,one of 等次修饰时应用。
你说的（3）和（4）也是对的 但是当这些先行词前有上述所说词修饰时就改用that了。
LiMing is the only one that wants to be a teacher 懂了。 你说的先行词是people 而people前又用all ，所以要用that了本回答被提问者采纳
