选D.这里是 the reason is that.这个句型的扩展应用,也就是说排除后,只剩下B和D.而在这里 the reason 后面多了个修饰 reason 的定语从句,说的是他给的那个没来的理由是.,如果是选B 的话,那么应该该为：The reason why he hadn't come to your birthday party is that...

D前面定语从句，后面宾语从句

答案D。 不能用why的原因，why后面接的是他不能来你的生日聚会而不是他为此而给出的原因。which这里代指reason引导定语从句。后面的that引导表语从句his mother was ill.

D前面是由which引导的定语从句来说明reason的，后面的that则是reason的固定搭配 the reason is that...原因和理由是...

B

选D

D
