“Dr. Smith， what is this？” “That is a time machine， Sally. With this machine， we can go back in time.”
“Wow！ Can we try it？”
“Of course！ Where do you want to go？”
“I want to see the dinosaurs.”
“No problem. Let's go！ Hop in， Tim！ Hop in， Sally！”
“Here we are. One million years ago.”
“Wow！ It looks very different. Everything is so big.”
“Yes， many of the plants are very big.”
“Dr. Smith， I don't see the dinosaurs.” “Look up.”
“Wow！ It is huge and scary looking. Will it eat me？”
“No， he will not eat you， Tim. He is a plant-eater.”
“Whew！ That's good.”
“Besides， he is only a baby. Look over there. That is his mother.” “WOW！”
“That dinosaur sure is big.”
“That is one of the biggest dinosaurs ever， Sally. It is called a Brontosaurus. It weighs more than 28 tons and is over 30 meters long.”
“I hope he does not step on me.”
“That would be very bad.”
“Let's explore more！ But be careful.”
“Look at that dinosaurs. He is smaller than the other ones.”
“Yes， he is an Iguanodon. He is a plant-eater too.”
“If he is a plant-eater， he will not hurt me. Hello， Iguanodon. How are you today？”
“Tim， watch out！”
“That was close. He almost hit with his tail.”
“Yes， the Iguanodon has a very powerful tail. He can use his tail when he is attacked.” “He also uses it to hit small boys.” “Ha！ Ha！ Ha！” “Maybe we should leave him alone.”
“That's a good idea， Tim.”
“Ah！ Look over there. Look at that dinosaur. He has a very large head. What's his name， Dr. Smith？”
“He is a Triceratops. His head is very big and it has three horns.”
“His horns look very sharp.” “Yes， they are. You can see one horn on his nose and the other two above his eyes. He uses the horns to protect himself.”
“I hope he doesn't poke me.”
“There's a very interesting dinosaur. He is very big，but he has a very small mouth. I wonder how he eats？”
“That is a Stegosaurus. He is a plant-eater， too. You are right. He does have a very small mouth.”
“Look at his back. It is bumpy.” “Those are called back plates， Tim. The Stegosaurus uses them for protection.”
“Dr. Smith， I think that all plant-eaters have some way to protect themselves.” “Yes， Sally， you are right.”
“Look over there. What's that？” “It looks like a giant egg.”
“Oh， don't touch it. It is a dinosaur egg. Soon， a baby dinosaur will hatch from it.”
“Really？ Do all dinosaurs hatch from eggs？”
“Why are the animals running away？
They look very scared.“
“Oh my！ That is a Tyrannosaurus.”
“He looks dangerous.” “He is. He's a meat-eater.”
“What does that mean？” “It means we should run.”
“That's right！ Run， Tim！ Run， Sally！
Let's get out of here.“
“Hop in！ Come on， we have to be quick.”
“Oh， no！ Here comes the Tyrannosaurus.”
“Hurry， hurry， hurry！” “Now， where is the present button？”
“Hurry！” “Here we are， safe and sound.” “That was fun！”
“Dr. Smith， what happened to the dinosaurs？”
“They became extinct， Tim.”
“Really！ How did that happen？”
“A very large rock crashed into the earth. There was a lot of smoke and the sun went away.”
“Without the sun， all the dinosaurs died？” “Right.”
“Dr. Smith， we have to go. Our mother said to be home by 5：00.”
“You had better go quickly.”
“Thank you， Dr. Smith. Good-bye.” “Good-bye.”
译文：在恐龙漫步的时候
“史密斯博士，这个是什么？”“那是一台时间机器，萨利。
用这台时间机器，我们能回到过去。“
“哇！我们能试试它么？”
“当然！你们想要去哪里？”
“我想要去看恐龙。”
“没有问题。让我们出发！跳进来，提姆！跳进来，萨里！”
“我们到了。一百万年以前。”
“哇！看上去很不一样。每一样东西都是如此的大。”
“是的，许多植物非常巨大。”
“史密斯博士，我没有看到恐龙。”“往上看。”
“哇！外形巨大和可怕。它会吃我么？”
“不，提姆，他不会吃你。他是食草动物。”
“唷！那就好。”
“此外，他只是一只小家伙。看那边。
那只是他的妈妈。“”哇！“
“那只恐龙一定是巨大的。”
“萨利，那曾经是最大的恐龙之一。
被称作雷龙。体重超过28吨身长超过30米。“
“我可不希望他踏在我身上。”
“那会变得很糟糕的。”
“让我们做更多的探索！但是要小心。”
“看那只恐龙。他比其他的恐龙要小。”
“是的，他是一只禽龙。他也是食草动物。”
“如果他是食草动物，他将不会伤害我。
哈罗，禽龙。你今天怎么样？“
“提姆，小心！”
“太近了。他的尾巴几乎击中你。”
“是的，禽龙有一条非常有力的尾巴。当他受到攻击的时候，他能使用他的尾巴。”“他也使用它击打小男孩。”“哈！哈！哈！”“也许我们不应该打扰他。”
“提亩，好主意。”
“啊！看那边。看那只恐龙。
他有一个非常巨大的脑袋。史密斯博士，他的名字是什么？“
“他是三角恐龙。他的脑袋非常大而且脑袋上有三支角。”
“他的角看起来非常尖利。”“是的。你能看到一支角在他的鼻子上，另外两支角在他的眼睛上方。
他使用角来保护他自己。“
“我可不希望他刺中我。”
“有一只非常有趣的恐龙。他非常大，但是他有一张非常小的嘴巴。我奇怪他怎样吃（东西）？”
“那就是剑龙。他也是食草动物。
你是对的。他确实有一张非常小的嘴巴。“
“看他的背部。是不平的。”“提亩，那些被称作背甲。剑龙用它们来保护。”
“史密斯博士，我认为所有的食草动物都有一些保护他们自己的办法。”“是的，萨利，你是正确的。”
“看那边。那是什么？”“看起来象是一颗巨大的蛋。”
“哦，不要碰它。它是一颗恐龙蛋。
很快，一只小恐龙将从里面孵化出来。“
“真的？所有的恐龙都是从蛋里面孵化出来的？”
“为什么这些动物在逃跑？
他们看上去非常恐慌。“
“哦，上帝！那是暴龙。”
“他看上去是危险的。”“是的。他是食肉动物。”
“那表示什么？”“那表示我们应该跑。”
“没错！提姆，跑！萨利，跑！
让我们离开这里。“
“跳进来！上来，我们要快。”
“哦，不！暴龙来了。”
“快，快，快！”“此刻，启动按钮在哪里？”
“快！”“我们在这里安全和可靠了。”“太有趣了！”
“史密斯博士，什么发生在恐龙身上了？”
“提姆，他们灭绝了。”
“真的！怎样发生的？”
“一块非常大的石头撞击了地球。
产生了很多烟，没有阳光了。“
“没有阳光，所有的恐龙死掉了？”“对。”
“史密斯博士，我们要走了。
我们的妈妈说要5点钟回家。“
“你们最好快走。”
“史密斯博士，谢谢你。再见。”
“再见。”
