3. 对…洋洋自得;为…自鸣得意
    If you say that someone is crowing about something they have achieved or are pleased about, you disapprove of them because they keep telling people proudly about it.

    If someone crows, they make happy sounds or say something happily.

    e.g. She was crowing with delight...
           她欢呼雀跃。
    e.g. 'I'm not sure I've ever driven a better lap,' crowed a delighted Irvine.
           “我想这也许是我开得最棒的一圈，”欧文高兴地欢呼道。

5. 成直线地;笔直地
    If you say that a place is a particular distance away as the crow flies, you mean that it is that distance away measured in a straight line.

    e.g. I live at Mesa, Washington, about 10 miles as the crow flies from Hanford.
           我住在华盛顿的梅萨，到汉福德的直线距离约为10英里。
