1-- Hi, this is Betty.

2-- Hi, Betty. It's Larry. I need to know how many smoke detectors are in your apartment.

1-- There was one when I moved in. Then I added one.

2-- Do both detectors have fresh batteries?

1-- I always keep them fresh. I don't want to burn to death.

2-- That's good. I have to come by there and check out all of the detectors.

1-- Not a problem. When will you be here?

2-- I'll be letting myself into all the apartments on Thursday at noon.

1-- If it's raining, make sure you wipe your feet before you come inside, okay?

2-- Not to worry. I'll be in and out of your place in a flash.

1-- 嗨，我是贝蒂。

2-- 你好，贝蒂。我是拉里。我想知道你的公寓里有多少烟雾探测器。

1-- 我搬进来的时候有一个。然后我又加了一个。

2-- 两个探测器都有新电池吗？

1-- 我总是让它们保持新的。我不想被烧死。

2-- 这很好。我得过去检查一下所有的探测器。

1-- 没问题。你什么时候来？

3-- 我将在星期四中午让自己进入所有的公寓。

2-- 如果下雨，一定要在进屋前擦干净脚，好吗？

1-- 不用担心。我会在一瞬间进出你的住处。
