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?
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?

Language points
1. … because we know how to deal with the ordinary diseases.
因为我们知道如何治疗普通疾病。
deal?with意思是“处理；安排；对付 ”，常与疑问副词how搭配使用。
如：How will you deal with the event? 你将如何处理此事？
how to deal with sth.意为“如何处理某事”，相当于how引导的宾语从句 how we should deal with …。
如：Please tell me how to deal with this event.
= Please tell me how I should deal with this event.
请告诉我如何处理此事。
Language points
2. But people don’t take as much exercise as they used to.
但是人们不像过去那样做很多运动了。
(1) as … as … 意为“像……一样……”，常用于同级比较，其否定形式为 not as / so … as …。主要用法如下：
①“as + 形容词 / 副词的原级 + as ”结构表示两者在某方面相同或相近。
如：This film is as interesting as that one. 这部电影和那部电影一样有趣。
② “倍数 + as + 形容词 / 副词的原级 + as”结构可表示两者间的倍数关系。
如：This ruler is twice as long as that one. 这把尺子是那把尺子的两倍长。
(2) used?to?do?sth.指“过去常常做某事”，没有人称和数的变化，其后常接动词原形。否定形式有两种：didn’t?use?to或used?not?to。
如：
I didn’t use to live there when I was a child.
I used not to live there when I was a child.
我小的时候不经常住在那儿。
3. I suppose that’s because more people have cars…
我想可能是因为更多的人有了车……
suppose表示“猜想”、“认为”，相当于think或guess。后接否定的宾语从句时通常将否定转移到主句上。
如：I don’t suppose he is really ill. 我看他不是真病了。
4. When the number of cars is doubled, the pollution is also doubled, or even worse. 当汽车的数量加倍时，污染也加倍，甚至更糟。
the number of 意为“……的数量”。跟复数名词连用作主语时，中心词是number, 谓语动词要用单数。
如：
a number of 相当于many，意为“许多”，修饰可数名词复数。作主语时，谓语动词用复数。number前可加large, small 等修饰，表示程度。
如：A number of / Many students are playing games. 许多学生在做游戏。
5. People seldom say they have enough spare time!
人们很少说他们有足够的空闲时间!
(1) seldom 副词，意为“不常，很少”，相当于not often，表否定含义。如：They seldom play football these days. 这些日子他们很少踢足球。
(2) spare 形容词，意为“空闲的，多余的”，常构成固定短语 in one’s spare time，意为“在某人的空闲时间”。
如：What do you like doing in your spare time? 你闲暇时喜欢做什么？
