课堂精讲 重点语句解析
一、课本原文
The world is in dangerOur world is in danger. We must do something to protect the environment. But, what are the main problems we face The greenhouse effectThe atmosphere around the Earth is necessary for all living things. It is like the glass of a greenhouse, letting sunlight in and keeping heat from getting out. Without it, the Earth would be the same as the Moon—cold and lifeless.When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide (CO2). Too much of this gas pollutes the atmosphere, and causes it to keep in too much heat. As a result of the greenhouse effect, the Earth's temperature is increasing. This causes sea level to rise, and in the future may cause cities to disappear.Cutting down forests Every year, we destroy nature by cutting down huge areas of forests. This makes the greenhouse effect worse because trees take in CO2 and produce oxygen. 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. This can result in floods and even more damage to the environment.Bad habitsMany of our habits cause pollution. People often use things once and then throw them away, or leave them on the ground as litter. This creates mountains of rubbish and pollutes our land and seas.In order to protect the environment, we need to take proper action. We should be different from many consumers and become “green consumers”. This means that we should only buy and use products friendly to the environment. We should also recycle as many things as we can. We can reuse things for the same purpose as before, or we can use them for new purposes. If we just learn to live in new and different ways, we can make a difference. 试试你的翻译能力________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
二、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
(1)本句是虚拟语气，句中的without …相于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不用was)，主句用would/should/could/might+动词原形。
(2)(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，什么东西都不会生长。
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)这条连衣裙跟我的一样。(汉译英)
_______________________________________________________________________________
2. When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide (CO2).(P35，L11)
当我们燃烧如汽油和煤这些燃料时，我们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 ____________ (call) Henry.
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，使得土壤表面很容易被雨水破坏。
解析
cutting down trees为名词短语作主语，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).
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意为“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.(同义句转换)
We should work hard ____________ ____________ ____________ pass the exam.
5. If we just learn to live in new and different ways, we can make a difference. (P35，L59)
如果我们学会用新的不同的生活方式生活，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)
