It's important to learn things about protecting environment. Here's a 4Rs rule for us.
·Reduce
If you want to reduce waste, you should use things wisely (明智的). A large number of trees are being cut down to make paper. If everyone uses paper carelessly and then throws it away, soon we would not have any trees left. Some other things are also being wasted, and people don't know what to do with waste in big cities, so it's necessary to reduce waste.
·Reuse
You should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you don't use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.
·Recycle
Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money, for example, cola cans are sent to a factory, where they're smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.
·Repair
If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it's better for you to sell the old ones or give them to other people who can use them after doing some repair.
26．The “Reduce” rule mainly requires us ________.
A．to use things wisely B．to cut down many trees
C．to use paper carelessly D．to use more and more things
27．What's the right order of recycling cola cans
a.smash them flat b.collect the used cans
c.smelt them d.send them to a factory
A．a-b-c-d B．d-c-b-a C．b-d-a-c D．b-d-c-a
28．The “Reuse” rule mainly requires us ________.
A．to throw away the old clothes
B．to collect waste paper and soft drink cans
C．to use both sides of paper
D．to give the old but usable things to the poor
29．Which sentence is about the “Repair” rule
A．When you leave a room, turn off the lights.
B．Take a cloth bag when you go shopping.
C．Don't use plastic bags.
D．If your chair is broken, you can repair it.

C．Save energy D．Good habits

参考答案：
1．A
【详解】句意：史密斯一家通常星期天在公园野餐。
考查冠词。a/an不定冠词，表示泛指；the定冠词，表示特指。结合题干“The Smiths usually have…picnic in the park on Sundays.”可知，这里的野餐表示泛指。因此用短语have a picnic“去野餐”表达。故选A。

3．C
【详解】句意：新型汽车太小，容纳不了很多人，但更大的模型将在不久的将来开发。
考查一般将来时被动语态。in the near future 在不久的将来，用于一般将来时态，models是动词develop（开发/研制）的受动者，本句需用“be done”被动语态结构。故选C。
4．A
【详解】句意：为了保护我们的环境，我们应该鼓励学生收集废纸和饮料罐。

50．句意：我们必须尽我们最大努力来保护我们的环境。try one’s best to do sth.意为“尽某人最大努力做某事”。故填best。
51．are 52．cut 53．has 54．What 55．or
【分析】本文是一篇说明文。文章主要讲述了人类的行为造成了地球环境恶化，并且还告诉了我们一些保护地球环境的可行措施。
51．句意：我们所做的事情中，一些对地球是有好处的，一些对地球是有坏处的。be good for“对……有好处”；第一段主要讲述事实，所以应用一般现在时，且本句主语为Some things，所以be动词应用are。故填are。
52．句意：我们砍伐了太多的树木，所以很多肥沃的土地变成了沙漠。根据后半句“土地变成沙漠”可知，人们是“砍伐”了树木。cut down“砍倒”。第一段主要讲述事实，所以应用一般现在时，且本句主语为we，所以谓语动词应用原型。故填cut。
53．句意：污染已经造成了许多严重的问题。根据句意可知，此句强调过去发生的事情（也就是污染）对现在造成的影响，应用现在完成时“have/has +动词过去分词”的结构。此句主语Pollution为三单，所以助动词用has。故填has。
54．句意：我们应该做些什么来拯救地球呢？第二段主要讲述了人类可以做的保护地球环境的措施，对措施的提问应用特殊疑问词what。故填What。
55．句意：我们应该做一切事情来保护它，否则我们会受到惩罚，失去我们的家园。逗号前后共有两个谓语，所以横线处应填连词连接前后句。前半句为保护地球，而后半句却是相反的结果，应用or“否则”来连接句子。故填or。
56．I’d like to, but I don’t know what I should do. 57．Yes. That’s easy. 58．Don’t take a bus or taxi unless you don’t have to. 59．Good idea. We have lots of paper at home. 60．Everyone should protect the environment.
【分析】本文是A和B两人的对话。A在教B一些保护环境的措施。
56．根据前文A询问B是否想要保护环境以及后文A在给B提供保护环境的措施可知，B的回答肯定是愿意但他不懂得要怎么做。故填I’d like to, but I don’t know what I should do.
57．根据前文…turning off the lights…可知，A提供的第一个保护环境的措施非常简单轻松。故填Yes. That’s easy.
58．根据前半句，A所提供的第二个保护环境的措施是骑自行车或走路，由此可推出A要说的后半句也是跟出行方式有关，再结合保护环境可知，A的后半句为“除非必要情况，不搭乘公交车或出租车”，因为这两种出行方式会造成空气污染。故填Don’t take a bus or taxi unless you don’t have to.
59．前文A提供的措施为Try recycling paper.，也就是循环用纸，由此可推测A提出的做法提醒了B他们家有很多纸张可以再循环利用。故填Good idea. We have lots of paper at home.
60．根据全文中心可知，A与B讨论了一些保护环境的措施，B最后说的一句应该是对他们前面对话的总结，也就是每个人都要保护环境。故填Everyone should protect the environment.
61．例文：
How to be a greener person
Now all the persons in the world are talking about being more environmentally friendly, which calls on us to be a greener person. Being a greener person means that we should try our best to pollute the environment less and be more friendly to the environment, which is easier said than done. To be a greener person, we should use bicycles or public transport services rather than driving your own cars or motorbikes. We should try to recyle what we use and try not to waste them. We can also be greener by saving water and electricity and so on. Being a greener person is being friendly to the earth as well as all the human beings in the world. Try your best and we will make a difference.
