Question

The reason ( )he gave for being late was ( )he forgot to use the alarm

A which ,because B why ,because C which ,that D that because 答案是C ，用which总觉的很奇怪啊

Answer 1

the
reason
后面是一个定语从句，the
reason
作
he
gave
的宾语，所以，这个空可以不填，也可填which
/that.（一般情况下，一个句子里含两个定语从句时，其中一个由that
引导，另一个就由which
引导。）
后一个空填that
是因为其作was
的表语，引导表语从句。
