Zero Conditional

We use the zero conditional To talk about a general “condition” or to describe something that usually happens. IF + SUBJECT + V1    /     SUBJECT + V1 SUBJECT + V1     /    IF + SUBJECT + V1 Zero Conditional Examples:  If I go to the beach, I take a towel. I put on my headphones if I use my phone on the bus. *When it is sunny in Miami, I go to the beach.  If it rains, I stay home. *When shows more frequency than if.

Zero Conditional Exercises and Practice  A good way to escape boredom is to find a hobby. Using the zero conditional, tell what each person does when they are bored. The first example is done for you.
1) Roscoe likes to fish. If Roscoe is bored, he fishes.
2) Morgan has a stamp collection. _________________________________.
3) Erica loves to cook. __________________________________________.
4) Michelle calls her boyfriend. ___________________________________.
5) My mother writes letters. ______________________________________.
6) Devon drives around town. ____________________________________.

First Conditional

We use the first conditional to talk about a real possibility. IF + SUBJECT + V1    /     SUBJECT + WILL + V1 SUBJECT + WILL + V1     /    IF + SUBJECT + V1 (Never use IF + WILL + verb!!!) First Conditional Examples:  If you visit Miami, I will take you to dinner. I will buy a red shirt if I don’t find a blue one. If I see her tonight, I will tell her about the party. *When I get home, I will look for the book. *When shows more certainty than if.

First Conditional Exercises and Practice  The American singer Doris Day sang a song called “Que Sera, Sera,” which is Spanish for “what will be, will be.” While we can’t know what the future will be, it’s fun to imagine. Using the first conditional, write a one-sentence response to each future prediction. The first one is done for you.
1) You will make a lot of money. _If I make a lot of money, I will move to the mountains and live in peace!
2) You will have six sons. ____________________________________________________________________.
3) You will travel to Antarctica. _______________________________________________________________.
4) You will become famous. _________________________________________________________________.
5) You will go to jail. ____________________________________________________________________.

Practice using the imperative with the zero and first conditional: Complete the sentences with your own ideas.
1.  When you arrive in Miami, _________________________________________.
2.  Welcome to my house. If you get hungry,_________________________________________.
3.  Don’t get upset if I _________________________________________.

The Imperative with Zero and the First Conditional

We can also use the imperative with zero and first conditional. Examples: If it rains tomorrow, use an umbrella.  /  When it rains, use an umbrella. Call your mom if you have time later.   /  Call your mom when you have time.

Second Conditional

We use the second conditional to talk about an unreal possibility. IF + SUBJECT + *V2    /     SUBJECT + WOULD + V1 SUBJECT + WOULD + V1     /    IF + SUBJECT + *V2 (Never use IF + WOULD + verb!!!) *We use the Past Tense form, but we are not speaking about the past.

Second Conditional Examples:  If aliens landed on earth tomorrow, I would be very surprised.  (Aliens won’t land tomorrow.) I would walk your dog if I had time.  (I don’t have time so I will not walk your dog.) If I **were the president, I would lower taxes.   (He or she is not the president.) I would go on vacation if I had money.  (He or she doesn’t have enough money.) **the verb to be: were is used with all subjects, although was is common in spoken English.

Second Conditional Exercises and Practice  A. Using the words in parentheses, complete the text below with the appropriate forms. 1. I am so busy this week that I can’t make it to my English class. I ______________________ (love) to come if I______________________ (to be, not) so busy. 2. Tell him I am sorry that I can’t help him. If I ______________________ (have) the money, I ______________________ (lend) it to him. 3. I live in Campodimele, Italy. If I ______________________ (live) in Miami, I ______________________ (study) English at LANGUAGE ON! B.  Please write a five-sentence paragraph about what you would do if world peace were declared tomorrow. Use the second conditional, as this is an unreal possibility. C. Write questions for a friend beginning with a Wh (question word) + would.  Discuss your answers.

1. If I have to work this Saturday,_______________________________________________________.
2. When I am bored,__________________________________________________________________.

Third Conditional

We use the third conditional to talk about a unreal possibility or condition in the past. IF + SUBJECT + HAD + V3    /     SUBJECT + WOULD + HAVE + V3 SUBJECT + WOULD + HAVE + V3    /  IF + SUBJECT + HAD + V3 Second Conditional Examples:  If aliens had landed on earth yesterday, I would have been very surprised.  (Aliens didn’t land on earth yesterday.) I would have walked your dog if I had had time.  (I didn’t have time so I did not walk the dog.) If I had been the president, I would have lowered taxes.   (He or she was not the president.)

Teacher’s Guide

Below are some ideas to use as you teach the conditional tense in your ESL classroom. Please feel free to add more by comment below or send me an email with your comments, question, and/or concerns. Happy teaching!

1. Have students describe good decisions they have made and then follow up with “If I hadn’t decided…..” etc.  You can repeat this activity with bad decisions that have been made. Make sure they focus on the 3rd Conditional. As a follow-up activity have them write a descriptive paragraph.

2.  Play “If” by Pink Floyd and have the students take notes. Then have them discuss and interpret the meaning of the lyrics as well as the uses of the conditional. They should then write 2 lines of their own in the same format as the original song, throw the lines on the floor and pick them up randomly to create their own song.

3. As a class, read and discuss songs that use the 2nd conditional.  (“If” by Pink Floyd, “If I had the World to Give” by the Grateful Dead….. there are many more out there!) Or, if you can find one song for each 2-3 students, have them work in pairs/small groups to discuss the song and its meaning before presenting to the class.

4. Assign random “What would you do if …?” questions and have the students discuss, first in pairs, then as a whole group.

5.  Ask students to imagine how the world would be today if certain events or inventions had not happened.  As a class discuss, for example, “If Steve jobs hadn’t invented the iPhone….” “If the USA hadn’t gotten involved in WWII..”   This can be turned into a research and presentation topic.

6. Teach the pronunciation of the contracted forms of the conditional in speech.  Teach word stress patterns associated with the conditional. Remind students of the contractions that we use for the past perfect.

a. I had never eaten it before. I’d never eaten it before.

b. She had read it. She’d read it.

c. It had been here.  It’d been here.

d. Dad had called.  Dad’d called

Teach students the contractions for would, could, and should with have. Tell them that they might even here the “woulda” form in casual speech.  Inform the students that there should be a little schwa sound (ə ) after the d in could, should, could before the have.  This will make it sound like could‘uh’ve.

a. would have  > “would’ve”

b. would not have > “wouldn’ve”

c. could have > “could’ve”

d. could not have > “couldn’ve”

e. should not have > “shouldn’ve”

Inform the students that in “usual” speech we place the stress on the noun, or the most important word in the sentence, and “glide” over the contractions very quickly.  Have the students write sentences using the contracted forms.  Have them underline the noun or nouns, or the most important word in the sentence, to mark where the stress is placed.  Students should practice reading their sentences until they can read them to the class fluidly.   The stress is particularly important for comprehension purposes.
