在宾语从句中what is happen,what is up,what is happen是不是都是陈述语序?
最后一个是what is the matter

在宾语从句中what is happen,what is up,what is happen是不是都是陈述语序?最后一个是what is the matter
不是what is happen而是：what has happened吧!
what is up/ what has happened / what is wrong都是陈述语序（即主语what+谓语is 后面是表语,what has happened是主谓结构）
what is the matter 是：代词+谓语+主语,疑问语序

首先，没有what is happen。可以是what has happened或what happens或what happened。
在宾语从句中what is the matter 语序要变为what the matter is，其他的不变。
