英语句子改错（1句）
he hadn't be staying up all night beacause he were too tired
答
was...he怎么用复数呢
答
He hadn't be stay up all night because he is too tired
答
原句语法词汇走远了= =
主要3个问题：
（1）句中2个动词——be和stay up
（2）because前后时态混乱，不知所云啊。。
（3）意思不通。按后半句看，显然是“他太累了因此没有熬夜”；既然“没有熬夜”那么all night就可以省略了。（“stay up all night”是“整晚不睡觉”的意思。）
按后半句的过去式改出来这样地：
He didn't stay up last night because he was too tired.（last night是我自己加的，看起来顺些~）
答
were改为was
答
be改为been
were改为was
