CA Before we leave on May 10, there will be a concert at the European Doctoral College of Strasbourg on May 6.

As we leave this critical High level Plenary Meeting, that faith is refreshed and strengthened.

And theoretically, I suppose if we opt for a film where someone gets brutally murdered or dies in a fiery car crash, we are more likely to walk out of that theater feeling like we've got it pretty good.

If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.

If we walk into the B15 iceberg when we leave here today, we're going to bump into something a thousand feet tall, 76 miles long, 17 miles wide, and it's going to weigh two gigatons.

Your departure came too soon, before we had our fill of your presence, before we understood the reality of your existence, and even before we were able to understand you.

And then maybe before I leave you ...

Think before you act!

Think before acting!

Let's go back before it begins to rain.

I think I'll leave before they get hostile.

We have to stop this before it happens.

You promised me to come back before summer.

Let's eat something before we go out.

Comb your hair before you go out.

The day We shall move the mountains , and you see the earth an open plain , We shall gather them together , leaving none behind .

And the Day when We move the hills and you see the earth flattened plain , and We shall raise all of them together so not leaving out any one of them .

And on the day We shall set the mountains in motion , and thou seest the earth coming forth , and We muster them so that We leave not so much as one of them behind

And beware a Day whereon we will make the mountains to pass , and thou wilt see the earth away plain , and We shall gather them , and We shall leave of them not one .

And ( remember ) the Day We shall cause the mountains to pass away ( like clouds of dust ) , and you will see the earth as a levelled plain , and we shall gather them all together so as to leave not one of them behind .

On the Day when We set the mountains in motion and you see the earth emerging and We gather them together , and leave none of them behind .

Bear in mind the Day when We shall set the mountains in motion and you will find the earth void and bare . On that Day We shall muster all men together , leaving none of them behind .

And ( bethink you of ) the Day when we remove the hills and ye see the earth emerging , and We gather them together so as to leave not one of them behind .

The day We shall set the mountains moving and you will see the earth in full view , We shall muster them , and We will not leave out anyone of them .

And on the Day when We shall set the mountains in motion and you shall see the earth a leveled plain when We gather them together , and would not leave even one behind ,

And warn of the Day when We will remove the mountains and you will see the earth prominent , and We will gather them and not leave behind from them anyone .

On the day when We will cause the mountains to travel around and the earth to turn into a levelled plain , We will also bring all human beings together . No one will be left behind .

And the day on which We will cause the mountains to pass away and you will see the earth a levelled plain and We will gather them and leave not any one of them behind .

The Day We shall make the mountains move and you will see the earth laid bare , and We shall gather all mankind together and shall not leave any one of them behind .

One Day We shall remove the mountains , and thou wilt see the earth as a level stretch , and We shall gather them , all together , nor shall We leave out any one of them .

No doctor, can I remember, ever asking me, Where have you lived?

So just check before it's finished.

I fell asleep before my father came home.

The train left before they got to the station.

Before you give orders, you must learn to obey.

I have to give back the book before Saturday.

But before we start, I need just to put these on.

We have to get him to the hospital before it's too late.

You should make sure of the facts before you write something.

You'd better get going in case you miss the bus.

They will hopefully be released eventually but not without first giving them, and other potential activists, something to think about before speaking out again.

Please phone me before you come.

Tom folded the paper before handing it to Mary.

You should turn off the light before going to sleep.

I always get nervous before I go on stage.
