今天我们要讲的俗语是：to throw for a loop。Loop是圆圈的意思。To throw for a loop是指“感到非常震惊”或者是“情绪很波动”。下面的例子是一个男朋友使得他的女朋友非常不高兴。这个女孩子说：

"Bill told me he couldn't take me out last night because he had to study for a big exam. So it threw me for a loop when I saw him walking into the movie theater with that stupid girl who sits next to him in biology class. (* No Soundfile)

她说：“比尔告诉我，他昨天晚上不能带我去玩，因为他要准备大考。所以，当我看到他和那个生物课坐在他旁边的傻姑娘一起走进电影院的时候我真是大吃一惊。”

考试分数有时也会令人出乎意料的，请听下面的例子：

"When I saw my semester grade for the chemistry course, it really threw me for a loop! I was sure I'd get at least a "B"--but there it was in black and white: a "D". So I barely managed to pass."

这个学生说：“当我看到我的化学课学期成绩的时候，我真是吓了一跳。我满以为我至少能得一个“B”，可是白纸上写的黑字是一个“D”。所以我刚刚及格。”
