托福官方指南就托福口语给广大考生提了这么一点建议：Increase vocabulary and learn to use idiomatic speech appropriately. 扩大词汇量并学着用含有大量习惯用法的语料。

美国人很喜欢在不同场合使用动词词组(phrasal verbs)。比如在跟朋友说再见的时候可以加一句Hit me up whenever you are free. 这里的hit me up就是一个动词词组表示没事多联系我哦，这样的表达不仅简单明了而且可以使语言更加生动。在备考托福口语单项的过程中，如果大家积累一些动词词组并能用在口语的回答当中应用的话不仅可以给考试加分，在以后的留学生活中也大有裨益。

在TPO口语文本里面就出现了一些动词词组比如：luck out(走运)， put it off(推迟)， bump into(偶遇)等。接下来笔者就对一些常用的跟out 和off搭配的动词词组做一下整理并以独立题目为例展示如何应用。

OUT：表示向外

drop out：跟quit同义即为退出

题目：

Do you agree or disagree with the following statement: A person should study in the university to be successful。

如果我们不同意的话可以加一句：There are lots of successful business men who drop out of university, like Steve Jobs, Bill Gates and Mark Zuckerburg。

sort it out/figure it out/ work it out: 都是解决问题的意思。

如果是加入something的话需放在词组后面如：

在第五题中可以使用这句话：He has two possible solutions to sort out the scheduling problem.

OFF：表示开始或者结束

表示开始的有

take off：The plane is about to take off. 飞机马上就要起飞了。

set off：I am setting off tomorrow on a business trip to America. 明天我去美国商务旅行。

kick off：The meeting kicks off at four o'clock sharp. 会议四点准时开始。

表示结束的有

switch off：stop giving your attention to someone or something译为停止对一件事件的关注.

题目：

Some students prefer to study for only one long time during a week. Others students prefer to study for several short times during a week. Which way do you prefer and why? Use specific reasons and examples to support your choice。

如果你选的是把学习的时间分为几段的话就可以说这么一句话：It's nice just to switch off, forget about study once in a while and do something fun like playing some sports, go fishing or even mountain climbing。

round off: 以xxx 为结束

在Describe a memorable activity with your friend. 这道题中我们以这句话结束：We rounded off the activity with happiness.
