You need to talk about this story.

I'm Catherine.

I'm Neil and this is news review.

Let's hear some more about that story from this BBC news report.

Lung disease, cancer, heart problems and stroke have all been linked to air pollution, particularly man made emissions from fossil fuels.

Now an international group of researchers has used a new method to model the impact on our health.

The team believes pollution lead to around 8.8 million premature deaths in 2015.

That represents an average shortening of life expectancy of nearly three years across the global population.

So serious situation here with air pollution it is shortening the average human life by a massive three years.

So quite a serious story today.

Neil is very serious story, isn't it?

It's not something you can really escape unless you can move to the countryside and everybody asking, No, don't do that.

Most people live in cities, and that's where it appears to be the worst.

So yeah, least three years off city people's life it would appear.

Okay.

The space between the two is called the span and I have my spine.

Is exactly one knocked upon the piano.

Well, you obviously born to play the You wouldn't think so if you heard May.

Yes, for the spot is a measure of distance.

Now it can be physical distance in that a span can be literally this, but it can also be a distance in time.

Your lifespan is the distance from the time between the start and end off your life.

It's kind of related to life expectancy.

My beard trimmers.

Things have a life span of about five years, and then the battery dies.

Okay?

And you have to get a new one to get a new one, even though it's rechargeable.

So yeah, I would say the lifespan of that object that devices is only about five years.

Eso lifespan isn't just for people who can also use it for objects.

Andi, have a useful life.

Yes.

Okay, let's have a summary time now for your second word, then, please, Catherine.

Study shortened, Make shorter.

It's pretty simple.

Very simple.

Yes, eight S h o R T E n.

Now the word short is the opposite of long.

That's quite simple.

And then we have the suffix e n to make something shorter.

Well, if you make something shorter, you shorten it.

Yes.

So if you make something longer Uru long, innit?

You do know?

I don't know.

You lengthen it, you lengthen it and length is actually unknown.

So there are a few exceptions.

Simply If you make somebody sadder, you can sadden them.

This is quite a saddening story.

But if you make somebody happier, you don't happy in them.

This is news review from BBC Learning English and we have one more headline to look at.

Please, we do so off Back to the UK In the Times dirty air is deadlier than war Aids on smoking combined deadlier, more likely to cause death than something else.

Yes, another little word that we had a suffix too.

And it goes into all kinds of wonderful things so deadly a d e a d l i e are the root of this wood is dead objective the opposite of a life.

We're not Deb's Neil.

Yes, we are not dead.

We will be one day.

But right now we're alive, which is good If you are the suffix l Y two dead, you get the word deadly.

Now if something is deadly, it's an object of we put onto another word to me and kind of very seriously really doesn't.

But if something is deadly that in the comparative form it's more likely to cause death.

So it's say here in the headline that pollution is deadlier, more likely to cause death than war, aids and smoking combines.

So, for example, if we consider the current Corona virus, which everyone knows about spreading around the world, it's it's deadly.

It's a deadly very It's very concerning very worrying.

But at the moment, um, it's not deadly, as some historical diseases like the plague.

Yes, which was deadlier.

The plague was deadlier than Corona virus at the moment.

But do, say, safe people, yes, so deadly and means more likely to cause death.

But the objective deadly is much more valuable, isn't it?

So it's an idea of everything being really serious.

And just on the point on point here I have heard people describe things as deadly.

Boring, deadly bore isn't mean.

It's so boring.

It's going to kill you.

Well, they may feel that way, and it is a quite idiomatic use.

But if something's deadly boring, it's so boring that you really, really, really, really hate it on.

If something is really, really, really serious.

Deadly serious, it's deadly.

Well, that's your deadly serious face.

Deadly serious face camera?
