  • Hello. We're doing the zero conditional today.

  • It's a useful grammatical structure in English.

  • Perhaps it's used for, particularly to those who are rules-based people, who like knowing

  • that A is going to result in B. My little nephew is like this.

  • Hi, Alex.

  • So, we're doing the zero conditional. And this is about something that is generally true, like a scientific fact.

  • If I press the toilet button, it flushes. Okay? "If", condition, result.

  • "If I do", "If I play, this happens."

  • So this is in present simple, and the result also in the present simple.

  • "If you heat ice, it melts." So it's like a scientific fact, it's like something...

  • This always happens in this same way. The condition always has the same result.

  • Now, the result, this bit here, it can also be in the imperative rather than the present simple.

  • So, I've put a little example here:

  • "If you do..." "If you visit Devon,"

  • -a place in the southwest of England-"go to Chagford."

  • Where I was born. Okay? It's a great place.

  • So, it's like "go to", it's an imperative. I'm telling you to do that.

  • So this is a structure of command.

  • "If you arrive late to my class again, you", and then I'm going to need to...

  • "You will have to go to the head master." Okay? It's the condition equals the result.

  • It's always the same. So if you're late, you have to go to the head master. Okay? Condition,

  • result, always the same relationship between the two.

  • Now, we can have a couple of different, alternative options here. Instead of "if" we could also

  • use "when" or "unless". I've written that unless... You know when... When's talking

  • about time, obviously. But "unless" means kind of if not, followed by the condition

  • and result. Condition always in the present.

  • So: "Unless if not he proposes", obviously that's quite weird, formal English.

  • The translation would be something like... Or the simplification:

  • "If he does not propose to marry you,"-to propose to marry you. Would you like to marry me?-

  • "refuse to go on holiday with him again." Okay? So: "refuse to go", there you've got

  • your imperative. Okay?

  • Now, we can change the order and put the result before the condition, and throw in a bit of

  • "if" and "when" and "unless" right there in the middle just to mix things up, mix the

  • bowl up. So, the result here is at the beginning.

  • "The boss, my leader, the person who is in charge is angry"

  • -again, notice present tense-"when I dance on my table."

  • Obviously, "when" could

  • also be replaced by "if" there. "...if I dance on my table". So, "when" would imply that

  • I maybe dance on my table quite a lot. But "if", I'm so scared of my boss that I don't

  • want to dance on my table. And "unless" would change it, so you'd have to have probably

  • a different condition there.

  • "The boss is angry unless I stay seated."

  • Okay, so let's just have another quick recap. Something that's generally true, like a scientific fact, like:

  • "If I cross the road without looking, I get knocked over."

  • Sorry, that's what the traffic's like in London. Pay attention.

  • Look to your left, look to your right before it's

  • safe to go. "If", condition, result. Present simple, present simple unless we're using

  • the imperative. "You will go to Chagford if you visit Devon."

  • And then we can mix in a

  • bit of "when" and "unless",

  • meaning changing the positive, negative affirmation, so:

  • "Unless he proposes to marry you," blah, blah, blah, this will be the result. This will always

  • be the result unless you do this. And then you can also have the result here and the condition here.

  • The boss is angry if you don't do the quiz right now

  • Good night. God bless.

  • See ya next time.
