Really great men are essentially modest. 真正的伟人大都很谦虚。

It was a pretty good offer, but he didn't bite. 这是个很好的提议，但他不感兴趣。

She is an extraordinarily beautiful girl. 她是个美丽非凡的姑娘。

He talks quite slowly and spaces his words out. 他说得很慢，每个词之间都有停顿。

This, I am so sorry to say, is almost entirely wishful thinking. 我很遗憾，这几乎完全是一厢情愿的想法。
