BBC Learning English

BBC Learning English is a fabulous website by the BBC. Among its many resources there is a Youtube Channel  full of explanations about grammar, vocabulary and other aspects of English. The video I'm sharing today, for example, explains how to use some linking words. This should help you with your compositions.


A continent of rubbish

We're learning about the Great Pacific Garbage Patch in 2nd Year of Bachillerato. It's a huge sea of plastic in the middle of the Pacific ocean and it causes a lot of environmental damage. It's quite unbelievable how polluted this planet is getting!

As a complement, we have also watched a TED conference by Charles Moore, the man who discovered it and who is fighting to make things better for our oceans. You can choose the language of the subtitles.

You can find more information about Charles Moore and his foundation at

Are we alone?

Many people wonder whether we are alone in the universe. Josh Worth's visualization 78 coins gives you a compelling argument to believe that well, there are probably other intelligent beings out there.

There is actually a scientific way to calculate how many civilizations are out there. It's called the Drake Equation. We need to look at how many stars there are in the galaxy, how many habitable planets there are, etc. The problem, of course, is that we really don't know what numbers to use to solve it... yet.

You can play with the equation itself at BBC Future.

You may ask yourself, then, could we ever see other alien civilizations? The answer is, unfortunately, no. Or at least, it would be very, very unlikely. The universe is simply too large.

How large? Well, light, which is the fastest thing that exists, needs to travel more than 5 hours just to get to Pluto. It takes only 8 minutes to reach Earth. (Again, you can check out another great visualization by Josh Worth to see just how large, and, well, empty, the Solar System really is).  

And that's just the Solar System. If you wanted to travel to the nearest star, Proxima Centauri, it would take you 4.22 years at the speed of light. It's 39,900,000,000,000 kilometres away!
