不好意思,今天比較忙,現(xiàn)在才回復(fù)你：
本題答案選B(我確信我會(huì)成為一個(gè)成功的人)
理由如下：
be sure后面可以接that從句,to do sth ,of sth/ of doing sth.
所以
A項(xiàng)應(yīng)該改為：I am sure of my success.
B項(xiàng)是正確的,其中success是抽象名詞具體化,指一個(gè)成功的人,所以可用a來修飾
C項(xiàng)will后面應(yīng)該加動(dòng)詞形式,應(yīng)改為:I am sure (that) I will succeed.
另外,
此句還可以改為：
I am sure of my succeeding.
I am sure to succeed.
但意思稍有不同:
I am sure of my succeeding.(大家都認(rèn)為我會(huì)成功)
I am sure to succeed.(我確信我會(huì)成功)
不知你是否滿意?!
