You will be calling the company you are renting from. When you call, you should verify if the rental car company has a location at the airport you are flying into. 

你要打电话给你租车的公司。当你打电话的时候，你应该确认租车公司在你飞机抵达的地方是否有定点。

"I need one at Los Angeles Airport."  

在洛杉矶机场我需要租辆车。

"I am flying into Los Angeles Airport."

If they have one, they will say they do and start asking you similar questions we already covered. We will not repeat them here, but I will have a practice session giving an example dialog on making a reservation below. 

如果他们有，他们会说他们有车，然后开始问你我们已经讨论过的类似问题。我们不会在这里重复，但是我将会给出一个对话练习，给出一个关于在下面进行预订的示例对话。

They might ask you for a credit card number on the phone. If you don't call and cancel, you might be charged. So if you need to cancel, remember to call and cancel at least 24 hours before the date. I am not sure if it is 24 hours. You should ask and verify. 

他们可能会在电话里问你的信用卡号码。如果你不打电话取消，你可能要付费。因此，如果你需要取消，记得在之前至少24小时打电话取消。我不确定是不是24小时。你应该去问清楚。

"If I need to cancel, when should I do that by?"

如果我需要取消，我应该什么时候去取消呢？

"As soon as possible, but in order to avoid a charge you should call 24 hours before the date."

越快越好，但是为了避免付费你应该在那日期前24小时打电话取消。

When you arrive at the counter, you will tell the person that you have a reservation.

当你到柜台的时候，你将会告诉这个人你有预订。

"Hi, I have a reservation under last name Lee." 

你好，我姓李有个预订。

"Hi, I have a reservation for a midsize car." 

你好，我预定了一辆中型车。

After that, they will confirm your information. They might ask you some duplicate questions, but we should have covered most of it already. 

之后，他们会确认你的信息。他们可能会问你一些重复的问题，但我们应该已经涵盖了大部分内容。
