Look at these following pictures:

Environment

Transport

Personal health

Work and free time

Now and then In the past:

There were fewer tall buildings.

The mountains were greener.

The rivers were cleaner and there were

more fish swimming in the rivers.

There were fewer cars.

People walked or cycled more often.

Transport was slower.

People lived harder.

Less medicine was known.

People got ill and died more easily and

more often.

People had more free time and lived

more relaxed.

Now and then

Now and then At present:

There are more cars.

People walk or cycle less than before.

Transport is faster. But there are more

traffic problems.

Tall buildings take up more room for

crops.

The air is not so clean and fresh as before.

The climate is warmer than before.

People learn more about diseases and

medicine.

So people are healthier and live longer.

People have to work harder and have

less free time. Life becomes busier

than before.

Now and then

Look at the photos and say:

1. What was life like in the past?

2. What is life like today?

There weren’t so many cars as there are today.

Work in pairs. Talk about the

photos.

Pronunciation — word stress

Concrete words: Noun. Verb. Adj. Adv. …

Empty words: prep. Conjunction. …

In a sentence, the concrete words should be

stressed and the empty words should not be

stressed.

That’s true. The advantage is that we know

more about medicine today. We’re better at

preventing illness. But people don’t eat as

well as in the past, and don’t take as much

exercise as they did.

All the words stressed are concrete words.

Listen and notice the stressed words.

Underline the words which you think the speaker will stress.

Yes. I agree. People walk or use their bikes

less, and they’re lazier. Faster transport

also makes more pollution. And that makes

life more dangerous and less healthy.

Now listen and check. As you listen, say the passage aloud.

Is life today better or worse than it was 50 yeas ago?

Work in pairs. Talk about your answer to the question.
