今天给大家介绍的是：To twist someone's arm。Twist是拧，用力扭转的意思。一个人要是给别人把手臂拧到身后去那是很难受的。To twist someone's arm这个习惯用语的意思也正是如此，它是指给某人施加压力，迫使他做你要他做的事。下面这个例子是一个学生说的话：

"I didn't want see that movie about Mozart, but my roomate twisted my arm. I'm glad he did -- it was a great show."

他说：“我本来不想去看那个有关莫扎特的电影的。可是，我同房间的同学硬逼着要我去。不过，看了电影后我倒很高兴，因为那个电影太好了。”

这个学生还算运气，尽管他本来不愿意，可是结果还不错。但是，被迫做的事往往会产生不愉快的结局。请听下面这位爸爸说的话：

"My son has been twisting my arm to let him take my car out on a date ever since he got his driver's license. This weekend, I finally let him take it. And now it's in the body shop for a thousand dallars of repairs: he had an accident on the way to pick up his girlfriend."

他说：“自从我儿子拿到驾驶执照以来，他一直闹着要开我的车去赴约会。这个周末，我终于答应了。可是，他在去接女朋友的路上出了车祸，现在我的车正在车库里修，要花一千美元呢。”

下面这个习语曾经在“每日一句”中介绍过，也和“arm”“leg”有关，大家就算是复习一下吧.
to cost/charge one's an arm and a leg 要价太高，不值得

例：
"Don't go to that fancy new restaurant. The food isn't very good and they charge you an arm and a leg for it!"
这个人说：“别上那个新开的高级饭馆去。他们的菜并不好，而价钱倒贵得要命。”
