EXERCISE 3

Reading

LIFE 100 YEARS AGO 1) Can you imagine what life was like 100 years ago?

2) Would want to live at a different time in history? Would want to visit a different time in history? What period in history would you want to visit? Read the following article. Pay special attention to unreal conditionals in the past.

Most of us are amazed by the rapid pace of technology at the beginning of the twenty-first century. We often wonder what life will be like 20 or 50 or 100 years from now. But do you ever wonder what your life would have been like if you had been alive 100 years ago? If you had lived around 1900 in the U.S., you would have earned about $200-$400 a year. You probably wouldn't have graduated from high school. Only 6 percent of Americans had a high school diploma at that time. If you had been a dentist or an accountant, you would have made $2,500 a year. If you had been a child living in a city, you might have had to work in a factory for 12-16 hours a day. If you had gone to a doctor, he probably would not have had a college education. 2

Unit 3-Grammar-Unreal conditionals

Only 10 percent of doctors at that time had a college degree. And if you had had a baby at that time, it would have been born at home. If you had gotten an infection at that time, you probably would have died because antibiotics had not yet been discovered. The leading causes of death at that time were pneumonia, influenza, and tuberculosis. What about your home? If you had been living 100 years ago, you probably wouldn't have had a bathtub or a telephone. You would have washed your hair about once a month.

Do you think you would have been happy with life 100 years ago? Why? Use A sentence in the article.

EXERCISE 4: Fill in the blanks with the correct form of the verb about life in the U.S. 100 years ago. EXAMPLE If you

had been

(be) a doctor 100 years ago, you

wouldn't have been

(not/be) rich.

1) If you ________ (have) a baby 100 years ago, it probably ________ (be/born) at home.

2) If you ________ (get) an infection, you probably ________ (die).

3) If you ________ (live) around 1900, you probably ________ (not/finish) high school.

4) You ________ (not/have) a car if you ________ (live) in the U.S. 100 years ago.

5) You probably ________ (word) if you ________ (be) child 100 years ago.

III. Future future If ... was/were/did ..., ... would/should/could/might do ... If ... should do ..., ... would/should/could/might do ... If ... were to do ..., ... would/should/could/might do ... EXERCISE 5 Translate the sentences in to English. 1) 如果我计算机考试失利，我将不得不明年再参加一次。

IV. Mixed Tenses in Condition Statements. We can mix a past condition with a present result. Past If you had lived during the 1950s, If she hadn't lost her job last month, Present you would have different way of looking at the world now. she would be able to take vacation now.

EXERCISE 6 Fill in the blanks with the correct form of a proper verb. These sentences have mixed tenses. 1)

She just came to the U.S., so she doesn't speak English perfectly. If she ________ here a long time ago, she ________ English much better. 2)

Luckily she didn't marry her high school boyfriend. If she ________ him, she ________ happy now. 3)

She didn't see the accident, so she can't tell you what happened. She ________ you what happened if she ________ the accident. 4)

You didn't come to class yesterday, so you don't understand the teacher's explanation today. You __________ the teacher's explanation today if you ________ to class yesterday. 5)

I didn't learn English as a child. If I ________ English as a child, I _________ so many problems with it now.

V.

We can put should, were, and had

at the beginning of an unreal conditional sentence. In this case, if is not needed. 

If you should make a mistake, you should not be embarrassed. 

Should you make a mistake, you should not be embarrassed. 

VI. Consolidation 1. Discussion: the exercise on Page 40.

2. Game: Let's see which group can still be alive in limited time.

Rules:



Think out many unreal conditional sentences as you can. 2 minutes.



Ask questions based on the sentences to the next group.



The next group answer the question and ask another group questions based on a new unreal sentence.



If the next group can answer the question without 5 seconds' hesitation and they can ask a new question, they can live on. If not , they are kicked out.

EXAMPLE:
