Wh Questions Result Clause If clause What happens if I don´t like it?

Grammar Rules: 1. Use present real conditionals sentences for general truths. The if clause talks about the condition, and the result clause talks about what happens if the condition occurs.  If it´s holiday, the store is closed.  If you use a credit card, it´s faster. Use the simple present in both clauses. We often use even if when the result is surprising. 

Even if it´s holiday, this store stays open.

2. You can also use real conditional sentences for habits and things that happen again and again.  If I shop online, I use a credit card. Use the simple present or present progressive in the if clause. Use the simple present in the result clause. 

If I´m surfing on the web, I use Google.

You can also often use when instead of if. This is especially true when you talk about general truths, habits, and things that happen again and again.  When Bill shops online, he uses a credit card.  When I´m surfing the Web, I use Google. 3. You can use modals (can, should, might, must…) in the result clause.  If you don´t like the product, you can return it.  If you have children, you shouldn’t let them shop online. 2


4. Use the imperative in the result clause to give instructions, commands, and invitations that depend on a certain condition.  If you change your mind, call the company.  If a site isn´t secure, don´t enter your credit card information. We sometimes use then to emphasize the result in real conditional sentences with imperatives or modals.  

If you change your mind, then call the company. If a site isn´t secure, then don´t enter your credit card information.

5. You can begin conditional sentences with the if clause or the result clause. The meaning is the same. Use a comma between the two clauses only when the if clause come first.  If I shop online, I save time.  I save time if I shop online. 2. Future Real conditionals. Statements If clause: Present If she studies

Result clause: Future she won´t fail the test. she is going to pass the test. if she doesn´t study she will fail the test. she isn´t going to pass the test.

Yes / No Questions Result clause: Future If clause: Present Will she pass the test if she studies? Is she going to pass the test

Short Answers Affirmative Negative Yes she will. No, she won´t. she is. she isn’t.

Grammar Rules: 1. Use future real conditional sentences to talk about what will happen under certain conditions. The if clauses gives the condition. The result clause gives the probable or certain result.  If I use this pen, I will pass the test.  If you feel lucky, you will expect good things.  If you feel unlucky, you will expect the worst. 3


Use the simple present in the if clause. Use the future with will or be going to in the result clause.

2. You can use modals (can, should, might, must…) in the result clause.  If she studies hard, she might get an A on her test. Even though the if clauses refers to the future, use the simple present. 

If she gets an A on her test, she will stop worrying.

3. You can begin conditional sentences with the if clause or the result clause. The meaning is the same.  If she uses that pen, she will feel lucky.  She will feel lucky is she uses that pen.. 4. You can use if and unless in conditional sentences, but their meanings are very different. Use unless to state a negative condition.  Unless he studies, he will fail the test. Unless often has the same meaning as if…not.  

Unless you are superstitious, you won´t be afraid of black cats. If you aren´t superstitious, you won´t be afraid of black cats.
