6. to read between the lines：to interpret the hidden meaning or a hidden message; to discern the true fact (从字里行间体会隐含的意义；领会言外之意或能了解其中的真正意义)

7. to let off steam：to give vent to one's anger （发泄、出气，像放掉蒸汽以减少压力似的。这与"to fly off the handle"意思相近，但比"to lose temper"委婉客气些 ）

What will you do if your wife lets off steam?（假如你太太大发脾气的话，你该怎么办呢？) (因为谈论的对象使对方的太太，所以语气要委婉客气些)。

但是谈到第三者，就可不必太委婉，可用 lose temper:
What will you do if one of your staff lose temper? （如果你的同事冲你发脾气你该怎么办呢？）
Occasionally we should be given a chance to let off steam.（我们应该不时的发泄一下情绪。）

Some women paid through the noses for their jewelry. (有些女人花大把的钱购买珠宝首饰。)

Mrs. Lin always takes center stage at a party. (林太太总能成为宴会上的焦点。)
President Bush takes center stage wherever he goes. (布什总统不论走到哪里，都是公众瞩目的焦点。)
His constant taking center stage could deprive him of his privacy. (他好出风头的毛病让他毫无隐私可言。)
