动词come是英语学习时最先接触到的单词，但也是考试中常常遇到的。come的常见意思是“来，过来，去”。它的过去时形式是came，分词形式是come。比如，Come here and look at this.到这儿来，看看这个。We came by train.我们是坐火车来的。
come另一个意思是“来临，到来，如期而至”，比如，I have been waiting for hours and she still hasn't come.我已经等他好几个小时了，可她还没有到。再比如，New Year is coming soon.新年很快就到了。
come on是最常见的短语，意思是“加把劲，加油”。比如，come on，child.加油,孩子！come on有“快点”的意思，比如，Come on, it’s time to go home. 快点，该回家了。再例如，Come on， we’ll be late.快点，我们要迟到了。
词组come across在考试中常常出现。它的意思是“碰到，找到（尤其指意外的、偶然的碰到、找到）”，比如说，I came across him first in Beijing.我是在北京第一次遇见他的。When carrying out the plan，we are bound to come across difficulties，but we are determined to overcome them all.我们在实行这个计划时会遇到困难，但是我们有决心把它一一克服。
短语come back意思是“回来”，比如，He came back two hours later.他两个小时以后回来了。另外一个意思是“回忆起，被想起”，比如，What the hero said many years ago often comes back to us.我们常常想起那位英雄很多年前说的话。再比如，It suddenly came back to me where I had seen the boy before.猛然间我想起了先前曾在哪里见到这个男孩。当它当“回忆起”讲时，come back 后面经常跟to 宾格人称代词me，us等。
come和from连在一起构成短语come from，意思是“从……来，来自”，比如，He comes from Beijing and I come from Guangdong.他从北京来，我来自广东。
常用词组come in的意思是“进来，到达”，比如，May I come in?我可以进来吗？Come in，it's raining outside.进来，外面在下雨。
与come in 意思相反的短语是come out，意思是“出来”。 比如，Come out, or I’ll bust the door down.快出来，不然我就砸门了。Her normally shy son had come out of his shell. 她那平时害羞的儿子已经开始活跃起来了。
另外一个在考试中常见的短语是come up with。它经常出现在词汇结构和完形填空中，意思是“赶上”，比如，On our way we came up with the party of hikers.行进路上，我们赶上了一群徒步旅行的游客。
短语come about指“发生”，尤其是指以难以防止的方式发生，比如，How did this dangerous situation come about？这样危险的局面是怎么出现的？ Can you explain how it came about that you were an hour late？你怎么会迟到一个钟头，对此你能做出什么解释？
