I don't doubt that Tom can finish the work in a hour.中的that可以省略吗?

问题描述:

I don't doubt that Tom can finish the work in a hour.中的that可以省略吗?

不可以、
如果省了就成了连个并列句

不能,肯定句是doubt whether&if,否定句是doubt that (有一个句型there is no doubt that)

这种情况下的宾语从句that是可以省略的
宾语从句that不可省略的情况有:
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.)

应该可以省略,doubt后边引导了一个宾语从句,that可以省略
