I'm ___ he won't come to join us for the picnic.
A sure B sorry C afraid D right
为什么A不对?谢谢。

解答:

I am afraid 和 I am sure不是用肯定句和否定句来决定的.

一般来说, I am afraid是说话人或听者不期望发生的事情. 和我们的恐怕差不多.

I am sure 是说话人对自己的判断比较确定的态度, 但是具体是否定句还是肯定句是不确定的.

I am afraid we are maybe late. I am afraid he wouldn't come.

I am sure he will come. I am sure he is not coming.
