第三课时 Reading (II) 课文精讲 一、重点语句解析
1. Without it, the Earth would be the same as the Moon — cold and lifeless. (P35, L8)
没有大气层，地球会变得跟月球一样阴冷而没有生气。
◇解析
本句是虚拟语气，句中的 without ... 相当于 if there weren’t ...。使用虚拟语气时，若表示与现在事实相反，则从句要用一般过去时（be 用were 而不用 was），主句用 would/should/could/might + 动词原形。
(be) the same as 表示“类似，相同”，通常指某个事物跟另一个事物很像。
◇举例
Without the sun, nothing would grow.
没有太阳，就不会有生物。
His last name is the same as mine. 我们同姓。
◇运用
(1) We couldn’t finish our work so early _______ your help. Thank you!
(2) 这条裙子跟我的一样。（汉译英）
_______________________________________without The dress is the same as mine.
2. When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide (CO2). (P35, L11)
当我们燃烧诸如汽油和煤这些燃料时，会产生一种叫二氧化碳的气体。
◇解析
when 在句中引导时间状语从句。而 called carbon dioxide 则充当后置定语，修饰 gas。
◇举例
It happened when I was living in the country.
这事发生在我住在农村的时候。
Have you seen the movie called Monster Hunt?
你看过《捉妖记》这部电影吗？
◇运用
(1) _______ the dinner was all over, everyone helped wash the dishes.
A. How???B. When???C. Before
(2) Once there lived a farmer _______ Henry.called
3. Cutting down trees also destroys the homes of the animals that live in our forests, and causes the surface of the soil to be easily destroyed by rain. (P35, L29)
乱砍滥伐也会破坏生活在森林里的动物的家园，引起水土流失。
◇解析
cutting down trees 为动名词短语作主语，表示一般的行为，通常后面接动词的第三人称单数形式。to be easily destroyed by rain 为不定式的被动结构作后置定语修饰 soil。
◇举例
Seeing is believing. 眼见为实。
I wanted the letter to be typed at once.
我想马上把信打好。
◇运用
(1) Getting up early is good for your health.（英译汉）
_______________________________________
(2) Someone took away my umbrella. I’d never expect it _____________ (return).早起对你的健康有益 to be returned
4. In order to protect the environment, we need to take proper action. (P35, L46)
为了保护环境，我们需要采取合理的措施。
◇解析
in order to为了……，常位于句首作状语，相当于 to ...；位于句中时相当于so as to。
◇举例
He got up early in order to catch the first bus.
他早起是为了赶头班公交车。
◇运用
We should work hard so as to pass the exam.
（同义转换）
We should work hard _______ _______ _______ pass the exam. in order to
5. If we just learn to live in new and different ways, we can make a difference. (P35, L59)
如果我们学会用焕然一新的生活方式生活，我们能对保护环境产生不可或缺的影响。
◇解析
if 在句中引导条件状语从句，表示一种虚拟的条件或假设。通常需遵循“主将从现”的原则。
◇举例
If you run, you’ll get there in time.
如果你跑的话，你就会及时赶到那儿。
◇运用
如果不下雨，我们就去。（汉译英）
________________________________________________We’ll go if it doesn’t rain. / If it doesn’t rain, we’ll go.
二、精读课文，用 5 ~ 6 句话进行概括
提示词汇：in danger; main problems; either ... or ...; do something to; protect
Our world is in danger and in need of our protection. The main problems we face are the greenhouse effect, cutting down forests and our bad habits. All these either cause pollution or destroy nature. Thus we must do something to protect the environment. Only if we become “green consumers”, we can make a difference.

Dear friends,
In order to make the environment more beautiful, we should do what we can to protect it. First, we should plant more trees and flowers to make our city more beautiful. Also, always remember not to throw rubbish or pour waste water everywhere. As we all know, water is becoming less and less. So it’s quite necessary to save water. For example, turn the tap off after washing. Last but not the least, we’d better ride a bike or walk when going out instead of driving a car.
In my opinion, if everyone tries his best to protect the environment, our city will become nicer and cleaner!
Thank you!
Wang Dong
