more fish swimming in the rivers.
There were fewer cars. People walked or cycled more often.
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.
At present:
There are more cars. People walk or cycle less than before. 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.

is like today.
There weren’t so many cars as there are today.
The road is much wider
than 1980s.
The buildings now are
taller than 1980s.

today.

Mum: It’s getting late, Betty. How is your
homework
Betty: Nearly finished. Mum, do you think that
life is better today than in the past
Mum: Yes, of course, I do.
Betty: I do too. People are wealthier today, and
they live longer than they did in the past.
Mum: That’s true. We know more about
medicine today, and there’s less fear of
getting ill because we know how to deal
with the ordinary diseases. But people
don’t take as much exercise as they used
to.
Betty: I suppose that’s because more people
have cars, and they walk or use their
bikes less.
Mum: Some people think life in the past was
simpler and healthier than today. More
wealth sometimes means less health.
When the number of cars is doubled,
the pollution is also doubled, or even
worse.
Betty: What about work Do people work as
hard as they did fifty years ago
Mum: Yes, and they sometimes work harder.
People seldom say they have enough

ask Mrs Li, our neighbour She’s
over seventy years old. She’s seen
how life has changed.

speak up!
She’s a bit
deaf now.

分析：
英语国家人士在连贯话语中使用不同的语音手段进行交流，包括重音。英语句子中，需要重读的词称为句子重音。一般来说，实词（名词、实意动词、形容词、副词等）需要重读，虚词（介词、连词、冠词等）不需要重读。
5. Read and predict which words the

◆ Some people think life in the past was simpler and healthier than today. More wealth sometimes means less health. When the number of cars is doubled, the pollution is also doubled, or even worse.
Some people think life in the past was simpler and healthier than today. More wealth sometimes means less health. When the number of cars is doubled, the pollution is also doubled, or even worse.
Now listen and check.
the number of 意思是“…的数量/数目”, 介
词of 同其后名词构成介词短语。当它作主
语时, 谓语动词用单数。
e.g. The number of students is about twenty.
学生人数大约是20人左右。
拓展：
a number of 意思是“一些，若干”
（= some), 后接可数名词复数或代词, 谓语动词用复数形式。词组中还可以加入形容词表示数量大或小。等:a large/small number of许多/少数）
e.g. A number of students in our class are
from Shanghai.
我们班的许多学生来自上海。
