Question

what's the matter变宾语从句是what the matter is吗

Answer 1

在宾语从句中,what is the matter和what the matter is 都可以用,要看你表达的是什么意思了.
这个涉及到matter的意义和用法问题.名词matter可以表示“物质（东西）”、“事情”的意思.例如：
“What is the matter?”the man asked．“这是什么东西?”那个人问.
The man asked what the matter was．那个人问这是什么东西.
在上面后一个句子中,what the mat- ter was是及物动词asked的宾语从句,the matter是宾语从句的主语,was是连系动词,连接代词what既是宾语从句的表语又是宾语从句的连接词.又如：
The woman didn't know what the matter was．那位妇女不知道那个东西是什么.
She was surprised to see what the matter was．她看到这个东西很惊讶.
但是名词matter常跟定冠词the连用,the matter可以是“困难”、“毛病”、“麻烦”、“失常”等意思,具有形容词性质,在句子中可作表语或定语.例如：
What's the matter（with you）?（你）出了什么事?
There's nothing the matter with the machine．这机器没有毛病.
The owner of the shop came up to see what was the matter．店主走近来看发生了什么事.
Is something wrong ／the matter with you?你生了什么病?（医生用语）
再看下面句子：
The doctor asked what was the matter ／wrong（with her）．医生问（她）生了什么病.
在上面句子中,what was the matter／ wrong（with her）是及物动词asked的宾语从句,what既是这个宾语从句的主语,也是宾语从句的连接代词,was是连系动词,the matter／ wrong）是表语.
