At present, too much carbon dioxide(二氧化碳) makes the earth warmer and warmer and causes terrible effect to human beings. To save our planet, to save ourselves, a new lifestyle called low-carbon life(低碳生活) becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.
To live a low-carbon life, we’d better save energy as possible. Turn off the lights and TV whenever they are not needed. If possible, use cold water to wash clothes or dishes. Take a short shower and try to take a cold one when the weather gets warm. Don’t do the cooking with electricity.
To live a low-carbon life, we should eat less meat. Everybody knows eating too much meat makes people fat and easy to have heart disease, but maybe you don’t know keeping animals for food produces even more carbon dioxide than all the cars in the world, and being a vegetarian can help reduce one and a half tons of carbon dioxide a year. Maybe it is a little difficult, but it’s really necessary.
To live a low-carbon life, we are supposed to do less shopping. When we go shopping, we may drive a car or take other transportation. On the one hand, these machines pollute the air and waste energy. On the other hand, most of us always buy some useless things because of some advertisements. It is not only a waste of money but also causes trouble to the earth, because as you know, making everything will produce carbon dioxide more or less.
There are many other ways to live low-carbon life, such as recycling things, planting trees and reusing textbooks. If we can keep it a habit in our daily life, the earth will become a safer planet for us to live on.

We spent a day in the country and picked a lot of flowers. Our car was full of flowers inside! On the way home we had to stop at traffic lights, and there my wife saw the bookshelf.
It stood outside a furniture（家具）shop. “Buy it,” she said at once. “We’ll carry it home on the roof-rack（车顶架）. I’ve always wanted one like that.”
What could I do Ten minutes later I was twenty dollars poorer, and the bookshelf was tied on to the roof rack. It was tall and narrow, quite heavy too.
As it was getting darker, I drove slowly. Other drivers seemed more polite than usual that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea.
After a time my wife said, “There’s a long line of cars behind. Why don’t they overtake（超车） ”
Just at that time a police car did overtake. The two officers（警官）inside looked at us seriously when they went past. But then, with a kind smile they asked us to follow their car through the busy traffic. The police car stopped at our village church（教堂）. One of the officers came to me.
“Right, sir,” he said. “Do you need any more help now ”
I didn’t quite understand. “Thanks, officer,” I said. “You’ve been very kind. I live just down the road.”
He was looking at our things: first at the flowers, then at the bookshelf. “Well, well,” he said and laughed. “It’s a bookshelf you’ve got there! We thought it was—er, something else.”
My wife began to laugh. Suddenly I understood why the police drove here. I smiled at the officer. “Yes, it’s a bookshelf, but thanks again.” I drove home as fast as I could.

A．the writer was poor and didn’t buy the bookshelf for his wife
B．the writer’s wife didn’t like the bookshelf at all
C．the writer was always glad to buy something for his wife
D．the writer was not very glad to buy the bookshelf for his wife

A．He could drive slowly and it was safe.
B．Other drivers would let him go first.
C．His wife could use a new bookshelf.
D．He could save a lot of money and time.
33．Why were the police and other drivers so kind to the writer
A．Because they thought the writer liked studying very much and needed a bookshelf.
B．Because they didn’t think it was polite to overtake a car with a bookshelf on it.
C．Because they thought somebody in the writer’s family had died and he needed help.
D．Because they thought it was dangerous to carry a bookshelf on a car.
34．Why did the writer’s wife begin to laugh

We live on the earth. We use the sea around us. What do we take from the ocean And what do we give to it
We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people. 36 .We take minerals（矿物质） from the ocean. We can get salt by evaporating(蒸发) seawater. 37 . Many other minerals, such as gold, can be also got from the sea, but not by simple evaporation.
Other gifts from the sea, such as seaweed (海藻) , can be also got from the sea. Seaweed becomes food of many kinds—even candy, and ice cream—as well as medicine. Believe it nor not, fresh water is another gift from the sea. We can’t drink ocean water. 38 .But ocean water becomes fresh water when salts are removed. In the future, we will find ourselves depending more and more fresh water from the sea.
The sea gives us food, fertilizer (肥料) , minerals, water and other gifts. What do we give the sea We pollute the ocean all the time. 39 .Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.
We are finally learning the truth. 40 .Hopefully, it is not too late.
A．Although the ocean is so large, it can’t hold all that we pour into it.

【分析】本文讲述了很多国家为了建房子提供木材，砍掉了很多树木。世界各地的许多年轻志愿者都在他们的假期工作，种植新的树木来取代它们。
51．句意：森林是地球的肺。根据后文的“Without them, it cannot breathe”可知，没有森林，地球无法呼吸，因此森林是地球的肺，主语forests是复数形式，因此“肺”不是一个，用复数形式，故填lungs。
52．句意：没有它们，它无法呼吸。位于情态动词cannot后，用动词原形，breath是名词，其动词是breathe，故填breathe。
53．句意：它需要森林来除去空气的二氧化碳，制造氧气。根据carbon dioxide...the air ，可知，表示来自空气的二氧化碳，故填from。
54．句意：在像新西兰、加拿大和巴西一样的许多国家，为了提供木材建房子，森林被砍掉。根据音标[pr 'va d]，此处用provide“提供”，位于动词不定式符号to后，用动词原形，故填provide。
55．句意：世界各地的许多年轻志愿者都在他们的假期工作，种植新的树木来取代它们。根据音标[v l n't z]，此处表示志愿者，有many修饰，用复数名词，故填volunteers。
56．句意：这些年轻的男女在种植新树木时面临许多困难。有many修饰，用复数名词，difficult是形容词，名词是difficulty，复数是difficulties，故填difficulties。
57．句意：天气可能非常热和干燥，或者它可能非常冷和潮湿。根据it may be very cold and wet.可知，此处与又冷又潮湿对应的，是又热又干燥，作为系动词be的表语，用形容词，故填dry。
58．句意：他们背着沉重的小树袋，在山里工作可能很危险。分析句子结构可知，此空在句中作主语，用动名词短语，故填working。
59．句意：他们种植不同种类的树木，以便鸟类和动物能生活在森林里。“种植不同种类的树木”是为了“鸟类和动物能生活在森林里”，so that“以便于”，引导目的状语从句，故填that。
60．句意：他们相信50年后他们的小树会变成美丽的森林。根据will become可知，此处用一般将来时，用in+时间段，故填in。
