帮忙分析一下这是什么从句
The health afficial said 12 suspected cases of influenza A(H1N1) were tested negative and that,so far,this city has reported no case of the virus.
这是什么从句?还有,那个said后面可不可以加that?
这是一个宾语从句.The health afficial作主语 said 作动词 从12到最后是一个大宾语从句.作said的宾语.由于此句是宾语从句 所以动词后面那个that可有可无.但that不是在所有情况下都可以省略.
附:宾语从句中that的使用方法.
从属连词that.如:
He told us that he felt ill. 他对我们说他感到不舒服.
I know he has returned. 我知道他已经回来了.(that省略)
注:宾语从句中that一般情况可省 ,但that在引导宾语从句时也并不是任何情况下都可以省略.在以下情况下,that不能省略.
1. Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句,that宾语从句放在and的后面时,that不能省略.)
大家都会看出所发生的事情并知道Tom非常害怕.
2.I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时,that不能省略.)
对他我一无所知,只知道他是南方人.
3.That he ever said such a thing I simply don’t believe. (that从句位于句首时,that不可省略.)
我简直不相信他曾说过这样的话.
4. We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句谓语动词与that从句之间有插入语,that不可省略.)
