Answer 2

取消括弧内的字

**********************

Actually, at first, I liked (like) him. At that time I thought (thougt) he was (is) so much different from the other presidents of America. I believed he would make the change and take the change to America, even to all over the world. But now, I think people are disappointed in (by) him to (at) some degree. People haven〉t seen those differences (that difference) he said in his speech(1).
But what I have learnt (learnt) from Obama (abama) is daring to take challenges
(challenge) and trusting myself.

(1) 不是错误,但可考虑用 he promised 来代替 he said in his speech
如果要有 speech,可加上补充资料,例如竞选运动时的演说,就职时的演说
甚至将speech改为众数
