about life in the past and life today. Please answer
the question: Is life today better than it was in the
past Yes, Betty
Betty: Can we write about anything, such as medicine
and pollution
Mr Jackson: Yes, think about how our medical knowledge has
grown and, of course, the environment is an
important part of our lives today.
Daming: And what about personal safety
魔法记忆
Mr Jackson: That’s a good idea, Daming. Do you think we’re
safer today
Daming: Well, I think there are fewer accidents than in the
past. Life is safer, certainly.
Mr Jackson: And why do you think this is true
Daming: Probably because there are so many laws to
protect us today.
Mr Jackson: OK, you can write about personal safety as well.
Remember to hand in your homework next
Monday.

Listen and read.
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.
魔法记忆
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.
魔法记忆
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 spare time！Why
don't you go and ask Mrs Li, our neighbour She's
over seventy years old. She's seen how life has changed.
Betty：That's a good idea. I'll go and ask her.
Mum：Remember to speak up！ She's a bit deaf now.

知识点

Nearly finished.快做完了。
almost 和nearly 的异同
考向一【难点】
相同点 almost和nearly在肯定句中可以互换，并且都可以用于行为动词的否定形式之前。
eg：It's almost/nearly nine o'clock.
差不多九点钟了。
I almost/nearly didn't get there in time.
我险些未能及时赶到那里。
魔法记忆
不同点 （1）almost可与表示否定意义的词，如 never，no,
none，nothing, nobody等连用，而nearly则不能。
eg：There is almost nothing left.
几乎什么也没留下。
（2）almost不可与not单独使用，而nearly可与not
连用，not nearly意为“远非”。
（3）一般说来，almost的差距比nearly小。
因此在“差一刻左右”开午饭时，可以说：
It's nearly lunchtime.快到午餐的时间了
在“差五分钟左右”的时候可以说：
It's almost lunchtime.马上就要吃午餐了。
魔法记忆
She said________nothing.
A．nearly
B．almost
C．hardly
典例
B
【点拨】用标志词法解答。almost可以和表示否定意义的词连用，根据句中的单词“nothing”可知选B。
魔法记忆
The volunteer teachers in the rural areas are________
all college students.
A．happily B．nearly
C．clearly D．freely
典例
B
【点拨】用词义辨析法解答。happily意为“幸福地”；nearly意为“几乎，差不多”；clearly意为“清晰地”；freely意为“自由地”。结合句意“农村地区的志愿者教师差不多都是大学生。”可知选B。
nearly为副词，意为“几乎；差不多；将近”。

许多人已读过这本书。
the number of ……的数量 跟复数名词连用作主语时，中心词是number，谓语用单数形式。 The number of the students in our school is rising year by year.我们学校学生的数量在一年年地增长。
