生活英语情景口语100主题 100. Is There Any Other Life Out There? 外星生物存在吗？

Dialogue one

Do you believe in UFOs?

Sure, a UFO is just species going from other planets. If you think about it, our space shuttles are UFOs.

I've never thought about like that before.

I've seen photos of UFO in America before, but they've all of darked up.

Do you think there's life on other planets?

I think there must be.

Why is that?

I don't think it will make sense if we are the only being in this whole world. The world is just far to big for that.

Do you think there's intelligent life trying to contact us?

No, but we are trying to contact them.

I suppose you are right.

I think the country is working hard to find a planet that we can live on in the future, so that when global warming destroys this planet, human kind will not become extinct.

Do you really think global warming will destroy earth someday?

There's a lot of evidence suggests it will. But I don't think it's gonna happen anytime soon.

Dialogue two

Guess what? I know something you don't know.

What's that?

How many planets are there in the Solar System?

That's easy. Everyone knows there are nine.

NOt anymore. Can you believe it? They've decided that Pluto is not a planet anymore.

Nice try. I wasn't born yesterday you know.

I am dead serious. They've decided that it's too small to be a planet. But actually they haven't yet agreed on how big something has to be in order to be a planet anymore.

That sounds crazy. But they can't just change their minds about things like that.

Yes, they can. If you remember correctly people used to believe the world was flat.

I suppose you are right. They also used to think that they were so important that the sun revloved around them, not the other way around.

We actually know relatively little about space and cosmos.

Do you that oneday we are able to travel to another planet for a vacation?

I suppose we could actually live on a planet outside the Milky Way.

Do you think we will get to meet Elites from outer space?

I hope not. I think it would be a threat to those of us that live in the earth.

You are so old fashined. That's what people used to think about people from another country.

Point taking. Hopefully one day we are living in an interplanet society.
