Answer 1

定语从句问题？ Finally he reached a lonely island ________ was completely cut off from the outside world.这里可以用that吗？ 答案：不能解析：此处缺少定语从句引导词，且充当从句的主语有实在意义。由于that只做引导词，无实在意义，所以不能用that，只能用which。

追问

that作为关系代词在定语从句中可以充当句子成分啊

追答

要有实在意义

that充当句子成分但无实际意义。这里需要的是要有实在意义，做句子主语，即the island(用which代替）was cut off……，而that则不能这样用。

Answer 2

对于事物做先行词，关系代词用that，人才能用who

Answer 3

选B。D中OF后面不能用that，C中whome在后面的从句中应作主语，但是whome不能作主语。

Answer 4

主语是A
prosperity，谓语appears，定语从句which
/
that
had
never
been
seen
before
，which做seen的宾语，同时引导定语从句修饰主语。

Answer 5

that可指人和物，但who只指代人，例子是限制性定语从句，用that做宾语可省
