高中英语单选

Immediately the informed decision has been made for his own sake,_________will mean you have no alternative.

A.what B.that C.which D.one
为何选B ，而不选C或D。
理由？谢谢

Answer 1

正确答案是B，因为这里immediately =as soon as用来引导时间状语从句的。那么只有that才能在后面的主句中充当主语，因为that在这里是指示代词。what ,which只能引导从句，显然前面有时间状语从句了，后半句应该是主句才对。
此题关键是immediately作连词使用。类似的副词可以当连词的还有instantly,directly，意思都是“一...就...”

祝学习愉快！

Answer 2

非限制定语从句，前面有，只能用that
