  • Hi, everybody. My name is Alisha.

  • Today, I'm going to talk aboutifclauses.

  • So, “ifclauses are used in a variety of different sentence patterns.

  • We use them to do a variety of different things as well.

  • So, today, I'm going to give kind of an introduction into a few cases where you can useif

  • clauses.

  • So, let's get started.

  • Okay.

  • First, I want to introduce two basic patterns for usingifclauses.

  • Ifclauses can come at the beginning of a sentence and can be followed by a main

  • clause.

  • I'll explain this a little more later.

  • So, we can begin with anifstatement and end with the main statement or the opposite

  • is also possible.

  • First, a main clause followed by theifclause, both are okay.

  • A few things I want to talk about today are how to use some of these sentences.

  • We can useifclause sentences, these kinds of patterns, for making plans and planning

  • questions.

  • By this I mean, questions about plans.

  • All of these include a specific condition introduced by theifstatement.

  • I'll explain a little more in just a moment.

  • We can use these for making plans, talking about plans, asking questions about plans.

  • We can use these for talking about our future activities, so potential activities in the

  • future.

  • We can use it for talking about past potential, so things different in the past, an action

  • done differently in the past and the potential different outcome in the future.

  • This is a very complex grammar point but this is very, very useful.

  • Okay, finally, we can use them to talk about advice and to give recommendations as well.

  • To ask for and give recommendations actually.

  • This is a very, very useful kind of sentence and I want to share a couple ways that you

  • can use these, as well as a couple grammar points inside the sentences, especially, in

  • the main clause that I hope you can use to make these kinds of statements and to make

  • these kinds of questions.

  • Let's take a look.

  • Okay, first, I want to look atifclauses.

  • So, “ifclauses, they begin with thisifstatement.

  • We use anifclause to express a condition.

  • A condition meaning some possibility or some potential.

  • For example, “If it's sunny tomorrow,” “If the weather is sunny tomorrow, blah,

  • blah, blah.”

  • So, we useif' at the beginning of theifclause to introduce our condition

  • that's going to lead us into the main clause.

  • So, in our main clause, the main clause can express a result, a potential result, it can

  • express a recommendation, it can express a question.

  • There are a lot of different things we can do with the main clause and a lot of different

  • types of grammar we can use.

  • So, I want to look at a few examples here.

  • Let's look at this first sentence which I already talked about.

  • This one, “If it's sunny tomorrow,” for example, “I'll go to the beach.”

  • Here I have myifexpression, myifclause, the condition is the weather, “If

  • it's sunny tomorrow,” I have here, “I'll go to the beach.”

  • You'll note that I've used “I'll”, “I willbecause, in this case, it sounds like

  • the speaker has just made the decision.

  • Maybe you've seen the video we did about the difference betweenwillandgoing

  • to.”

  • So, when we usewill,” it's often used in times when we've just made a decision,

  • during the conversation.

  • So, here, “If it's sunny tomorrow, I'll go to the beach.”

  • Please be careful, however, do not usewillin this sentence, in this part of the sentence.

  • For example, some people say, “If it will be sunny tomorrow,” it's not correct.

  • We cannot usewillhere.

  • We need to usewillin the main clause.

  • If it's sunny, I'll go to the beach.”

  • Please be cautious here.

  • So, this sentence means, “If the weather is nice tomorrow, my plan, I just decided,

  • is to go to the beach.”

  • Let's look at one more sentence that is similar.

  • If you pass the test,” here is my condition, “If you pass the test,” here, “you'll

  • get a certification.”

  • You'll get.”

  • So, once more, you can see, I've usedwillhere in the contracted form.

  • You will get a certification if you pass the test.”

  • So, keep in mind, as I said before, we can swap, we can reverse the sentence patterns

  • and the sentence meaning remains the same.

  • Just please be careful, if you're usingwill,” make sure it's in your main clause, not in

  • yourifclause.

  • Let's take a look at something a little bit different.

  • Here I have, “If we got approval for the project,” “If we got,” here you'll see,

  • it's not the present tense.

  • If we got approval for the project,” this is the past participle form here.

  • If we got approval for the project, we would begin on Monday.”

  • So, this is a potential situation.

  • This is a situation, you can see I've used the past participle here andwouldin

  • the main clause, by changing the tense of my verb, I change the potential of the situation.

  • This is a sentence we might use when making a proposal.

  • If we got approval for the project,” in the future, in theory, so meaning in possibility,

  • this is not certain, it's not in my control now.

  • But, if this were the case, “If I got the approval for the project, I would--we would

  • begin on Monday.”

  • This is a future potential situation, something that is potentially--I'm potentially capable

  • or we are potentially able to do but it has not been decided yet.

  • In these cases, we need to usewouldin the main clause.

  • Okay, so, let's take a look at the next sentence here.

  • Similar to the previous sentence I talked about.

  • The sentence--theifclause here is, “If I hired you for the job,” you can

  • see the verb here is also different as we talked about in the previous sentence.

  • If I hired you for the job, you would get $50,000 a year.”

  • So, once more, this is a future potential sentence and we know that because of the verbs

  • that are chosen.

  • If I hired you,” we use the past participle here.

  • We need to applywouldin the main clause to show the future potential of this situation.

  • So, please be careful.

  • We've talked about two types ofifclause statements now.

  • Let's go to one more, yet one more example of how to use this grammar.

  • This is a past potential and a resulting possible outcome from a past situation.

  • So, let's look at theifclause first.

  • If they had left the house earlier, they would have been on time.”

  • Here, once more, you can see, I've got, “If they had left the house earlier,” “If

  • they had left,” I've gothadhere.

  • So, we need to use have or had in the past tense here plus the verb.

  • And then, again, we usethis would have been on time.”

  • We have created a more complex grammar sentence.

  • This shows, “if something had been different in the past, a different outcome would have

  • resulted.”

  • We need to usewouldplus ourhave been,” for example, in this case.

  • Let's take a look at one more sentence.

  • If I had studied a little more,” here's our verb phrase.

  • If I had studied,” so, I did not study very much.

  • If I had studied a little more, I would have passed the test.”

  • Here, I've mentioned too, “mightis also possible.

  • Maybe the speaker doesn't know for sure the definite outcome, in this case.

  • So, we can usewould,” to express certainty, “might,” to express a lower level of certainty.

  • “I might have passed the test,” “I would have passed the test.”

  • And, again, we have the verbhave,” and in this case, “passed the test,” as well.

  • So, you can see the grammar becomes progressively more complex in these situations.

  • The last ones I want to talk about, just two more, are recommendations and questions.

  • You can use anifclause to introduce your condition.

  • Like, “If you go to Paris,” for example.

  • Here, in your main clause, you can give a recommendation.

  • Like, “you should,” in this case.

  • I've usedshould,” “you should visit the Louvre,” or, “go to the Louvre,”

  • or, “try some food,” something like that.

  • You can use a recommendation expression in your main clause here.

  • The final thing I want to talk about is making a question in your main clause.

  • For example, “If it rains this weekend, what do you want to do?”

  • So, this is a situation where you're looking for the listeners' opinion.

  • What do you want to do?”

  • You can use an expression like a question, “What do you want to do?”

  • What do you think we should do?” in your main clause to do that.

  • Okay, so, those are a few different ways that you can useifclauses to create a variety

  • of different expressions in different statements.

  • So, we've talked about, quickly, about a few examples of each of these so give them a try.
