欢迎指正：the same as 的用法总结

liverping

5)在下列情况下，只能用that而不能用as:

as只能是关系代词，但是that可以作为关系副词和关系代词的。

如：I live in the same city that he lives.此处只能用that，而不能用as;

但是，如果稍加改动，I live in the same city as he lives in。则就可以用as了，因为,as此时是关系代词（当然，此处也可以用that）。

提问一下：按照这种解释那原题中A选项是否在published后面加上in 就是正确的呢（改were为was）？谢谢

A. A letter by Mark Twain, written in the same year as The Adventures of Huckleberry Finn were published,

C. A letter by Mark Twain, written in the same year that The Adventures of Huckleberry Finn was published,
