【一起听英语】垃圾处理

生活水平提高了，垃圾自然也就多了。当今社会，保护环境很重要的一个环节也是如何处理垃圾.......

Rob: Hello and welcome to 6 Minute English. I’m Rob and joining me in the

studio today is Jennifer. Welcome, Jennifer!

Jennifer: Hi there. Now Rob, I believe our subject for discussion this week is a load

of rubbish?!

Rob: I wouldn’t put it exactly like that. We are talking about rubbish – or to use

another word – junk – and hearing some language about a subject that is

out of this world – space junk.

Jennifer: Yes, here on planet Earth we don’t like seeing rubbish or litter on our

streets but in space the problem is far more serious and it could even be

catastrophic – so it could lead to a serious disaster.

Rob: Well, we’ll hear more about that in a moment and also find out how

scientists are going to clear up this mess. But, before that, I think we

should blast off with a space-related question. Now, did you know, the

Russian satellite, Sputnik, was the first man-made object to be blasted

into space? Do you know in which year it was launched?

a) 1957

b) 1960

c) 1967

Jennifer: I think it was in the sixties perhaps so I’m going to say b) 1960.

Rob: Well, we will find out if you are right at the end of the programme. So,

we’ve mentioned that junk – or debris¹ – floating around in space is a big

problem. It can take a long time to tidy up your house so imagine the

challenge that lies ahead in tidying up the great mess in outer space.

That’s something that’s been discussed at a recent conference on space

debris in Germany.

Jennifer: Well, tidying up space is not something I would like to do! But how did all

this rubbish end up floating about up there in the first place?

Rob: A good question. For the past 50 years, man has been sending objects like

rockets and satellites into orbit. In fact, even now around 70 satellites are

sent into space every year. But when they are no longer needed they are

just left up there and not disposed of – or put away somewhere where

they won’t cause harm. They were never designed to be brought back

down to Earth.

Jennifer: These old fragments – or bits of technology continue to circle the Earth

and become a threat to spacecraft which are operating up there. In 2009,

for example, two satellites accidently hit each other – or collided - causing

them to break into small pieces.

Rob: That’s added to the millions of small pieces of junk that are just floating

around that might never be recovered – in other words collected and

brought back down to Earth. Let's hear more about this Professor Richard

Crowther, Chief Engineer at the UK Space Agency. What other issue does

he compare this problem with?

Professor Richard Crowther, Chief Engineer at the UK Space Agency:

Perhaps the most alarming factor is, even if we stop launching anything in to orbit from

now on we would still see collisions occurring between satellites currently up there. But

we recognise that if we want to actively² manage this problem we have to do something

now. It’s like global warming – we’re not 100% certain that a certain scenario³ will occur

but we have a pretty good idea of what’s dominating and what’s influencing the

evolution.

Rob: Professor Crowther mentioned an ‘alarming factor’, so a very worrying

piece of information, that even if we didn’t put any more objects into

space there is already a risk of the current satellites hitting each other.

These satellites are the ones that we depend on for communications,

watching TV, weather forecasting and for using satellite navigation –

satnavs.

Jennifer: Well, that’s why he says we have to do something now. He predicts

catastrophic – or very bad - collisions could occur every five to nine years

unless something is done. He compares the problem with global warming.

It’s serious. We’re not sure what might happen in the future but we do

need to protect against it.

Rob: Maybe they need a huge vacuum cleaner, or what about a giant magnet to

gather up all that metal clutter⁴?

Jennifer: Hmm, I think you’re talking rubbish – or saying things that will never

happen. But there are some more realistic ideas being developed such as

using nets, lasers to destroy the pieces of junk and a harpoon⁵ to catch

them.

Rob: It sounds like science-fiction – something you just read about in stories.

But are these ideas really being developed?

Jennifer: Yes, although research is in its very early stages. A harpoon could be fired

at a redundant⁶ - or no longer working - satellite and then it would be

pulled downwards⁷ to burn up in the atmosphere.

Rob: But, surely up in space, lasers and harpoons⁸ might be thought of as

weapons which could be used in a space war?

Jennifer: Well, according to Professor Richard Crowther, it is something that will

need managing. What does he suggest?

Professor Richard Crowther, Chief Engineer at the UK Space Agency

If you’ve watched James Bond films over the years, you know that anything with a

harpoon, with a laser, with a net in space, has the potential to grab another spacecraft

and destroy it, so what we need to do is build reassurance⁹ within the space community

and demonstrate that the systems being proposed are peaceful in their nature but also

peaceful in the intent and the way in which they are going to be used.

Jennifer: He talked about reassuring¹⁰ – or explaining – that the new technology is of

a peaceful nature. That means it’s not for use in war or violence. He says

the intent – or the purpose behind using it – is good not bad.

Rob: OK, well there’s one thing back on planet Earth that needs tidying up and

that’s the answer to today’s question. Earlier I mentioned that the Russian

satellite, Sputnik, was the first man-made object to be blasted into space.

But did you know in which year it was launched?

Jennifer: I said b) 1960.

Rob: And I’m afraid you were wrong! It launched in 1957. OK, we’re almost out

of time now, so Jennifer, could you remind us of some of the words and

phrases we’ve heard today?

Jennifer: Yes. They were:

junk

mess

debris

disposed of

recovered

clutter

talking rubbish

redundant

Rob: Thanks. Let’s get our feet back on the ground now and say farewell. Bye

for now!

Jennifer: Bye!
