I have no doubt______ Bob will work out all the math problems.

问题描述:

I have no doubt______ Bob will work out all the math problems.
I have no doubt_____ Bob will work out all the math problems.
Awhether Bthat

B
如果是有疑问,就是whether
这里是没有疑问,显然后面是陈述句怎么区别有没有疑问(我可不可以理解Bob是否做出数学题)doubt是有疑问,have no doubt是毫无疑问,说明后面是陈述句,鲍勃肯定会怎么样,用that 如果是have doubt,那么,就是我怀疑他是否怎么样,宾语从句或者是间接引语里,一般疑问句用if whether引导
