A：There is a tornado warning on. My mother just told me she heard it on the radio.有一個龍卷風的警報，我媽剛剛告訴我她從收音機聽到的。

B：What is a tornado warning?什么是龍卷風警報?

A：It means that a tornado has been seen somewhere in the area.就是有一個龍卷風已經在這個區(qū)域出沒。

B：Really? In New Berlin?真的?在新柏林?

A：No. Not necessarily in town. But in southern Wisconsin somewhere.A tornado has been spotted. They have two stages here.This is what is called a tornado watch. That means that the weather conditions are perfect for a tornado.不，并不一定在城里，但在南威斯康辛州某處。有一個龍卷風已經被監(jiān)控。他們分為兩個等級，現(xiàn)階段稱做龍卷風警戒，表示天氣狀況是形成龍卷風的最佳狀態(tài)。

B：I understand. They think a tornado might come.我懂了，他們認為龍卷風可能會來襲。

A：Yes. People should look out, because maybe there will be tornadoes coming.So it's called a watch.是的，大家要當心，因為也許龍卷風就要來襲，所以稱做警戒。

B：And the second stage is called a tornado warning.而第二等級稱做龍卷風警報。

A：Yes. If a tornado has been spotted, they announce a tornado warning.So if there's a tornado warning on, it means a tornado is out there somewhere.是的，如果龍卷風已經被監(jiān)測到，他們就會宣布龍卷風警報。因此，若已提出龍卷風警報，那表示一個龍卷風已在某處。

B：It's scary.真可怕。

A：Well. Tornadoes can be dangerous, it's true.If we hear something like a loud train coming, then we have to go in the basement.嗯，龍卷風可以很危險的，是真的。如果我們聽到什么像轟隆的火車接近聲的，我們必須進入地下室。

B：What do you mean a loud train?什么是轟隆的火車?

A：That is what tornadoes sound like. They sound like trains. They're very loud.那就是龍卷風聽起來的聲音，他們聽起來像火車聲，非常大聲。

B：But if you hear them coming, isn't it already too late?但是如果你聽到它們來臨了，不是已經太晚了嗎?

A：Maybe. It depends on the tornado.Some can move across the ground at 200 miles an hour.That is very fast. Others aren't so fast.很可能，要視龍卷風而定。有些一小時可以在地面橫越兩百里。那是非?？斓?，其他的沒這么快。

B：Have you seen a lot of them?你看過很多龍卷風嗎?

A：I've only seen one in my life. I was looking out the window. It was around two miles away. It was very interesting to watch.But it was heading toward my friend's house. So I quickly called them on the phone.我這生只看過一次，從窗戶望出去的，大概在二里外的地方，觀看是很有趣的。但是它直掃向我朋友的房屋，所以我趕緊打電話給他們。

B：Did it hit their house?它有打中他們的房屋嗎?

A：No, it didn't. But they are glad I called them.沒有，但是我朋友很高興我打電話給他們。

B：What were they doing when you called?你電話時，他們在做什么?

A：They were all sitting in the living room watching TV.They had no idea a tornado was coming toward their house.If it had hit them, they could have all been killed.他們全都坐在客廳看電視，一點也不知道龍卷風正向他們的房子接近。如果當時真打中他們，他們可能全都一命嗚呼。

B：That's terrible. Do many people die in tornadoes?真是太可怕了。有很多人喪生于龍卷風嗎?

A：Not so many really. But a lot of houses are destroyed sometimes.是不太多啦，但是有時候很多房屋被摧毀
