这两道英语选择题有什么区别，请详细说一下，谢谢
4. Is this the shirt ______ he often wears?
A. whom B.the one C. what D. that
5. Is this shirt _______ he often wears?
A. which B. the one C. what D. that
答：这是两道经典的定语从句对比题。为增加题目的巧妙性，两题句只有一字之差，有的甚至四个选项设计相同，我稍加改动如上。
要做对这两题，不仅要熟悉定语从句相关的知识，更要会句子分析，能断句，知道主系表句型。
这两个题句的巧妙之处在于用了一般疑问句。使得两个句子看上去只有一字之差。上一句有the,下一句没有。选项就不一样。如果将两个句子改成肯定句，题目就非常简单：
4. This is the shirt ______ he often wears.
A. whom B.the one C. what D. that
5. This shirt is _______ he often wears.
A. which B. the one C.whom D. that
很明显，上一题空需要填一个关系代词，可以是that,也可以是which,甚至可以不填。
第二题明显缺少一个表语（同时又是后面的这个定语从句的先行词），为避免重复，用the one,后面的关系代词that省略了。
注：what引导名词性从句也可以。我临时改了。
网上应该有更好的对比题。我给你找一找。
Is this the museum _____ you visited the other day?
A. that B. where C. in which D. the one
Is this museum _____ you visited the other day?
A. that B. where C. in which D. the one
