Question

英语中what的用法？

Most scientists believe the migration path include a land, now underwater,that linked Asia with what is now the state of Alaska.
what在这里怎么用？可以改成that吗？或者说 what now is the state of Alaska.

Answer 1

Most scientists believe the migration path include a land, now underwater, that linked Asia with what is now the state of Alaska.
先昌友说这句话的意思：
大多数科学家认为， 迁移包括陆地， 现在是在水下， 以致于亚洲曾经连接着仿基现在的阿拉斯加州。
what is now the state of Alaska.
是宾语从句， what作为代词表示那种样子， 不能用耐大槐that 代替。

Answer 2

回答如下：
不可以那样改。what引导庆誉的从句是宾语从句，作介词what的宾语，what在从句中作主语。that从句不能作介词宾语，只能作动词宾语，誉罩段并且that在闷者从句中不作任何成分，无意义。

Answer 3

1. what引导宾语从句，what在磨念从句中作主语，厅游绝而that在宾语从句中是连词，不能作主语，所以，不能用扮姿that
2.what引导名词从句时，相当于the+n+that
3.now一般位于be动词（或助动词）后，行为动词前

Answer 4

共有两种用腔毁法：1, 作特殊疑问词运用，此圆做如：What does Stanley cook on Sunday ? 2, 作从句关系词运用森衡，如：You mostly like to do what your interest is on Saturday.
