6 News English from bbclearningenglish.com Hello and welcome to 6 Minute English, I'm Alice.
And I'm Rob.
Hey, Alice, I read in the paper recently that the substance called fluoride might be bad for our health,
but it's in nearly every brand of toothpaste, isn't it?
You shouldn't believe everything you hear, Rob.
Fluoride protects our teeth against decay.
But there's a theory that drug companies are using fluoride to affect our brains and make us all dumb.
That's ridiculous, Rob.
Well, I'm not sure if I believe it or not, but it's worrying me.
Do you also worry that the moon landings never really happened?
It's funny you should mention that because, yes, I wonder about this too.
Apparently, in the 1960s television footage of the moon landing,
the American flag is fluttering,
and there's no air on the moon, so the US government must have faked it.
To fake something means to make something that isn't true appear to be real.
I didn't realise you were so gullible, Rob.
And that means easily persuaded to believe something.
I'd just like to question things.
