阅读下面的短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项并在答题卡上将该项涂黑。 A
Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good
to others, you will feel happy, too. All these are your happiness. If you notice them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties,
you can say loudly you are very happy, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转 ) door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
21. When you do something wrong, _______________.
A. you may correct it
B. you will have no chance to challenge yourself
C. anybody will laugh at you
D. you will be happy
22. Which is TRUE according to the passage?
A. When you get success, your friends will be very proud of you.
B. You can get help from others when you make mistakes.
C. You can still be a happy person even if you have little money.
D. All the above.
23. Why do we say “Happiness is not the same as money”? Because _______________.
A. money always brings happiness
B. money doesn’t always bring happiness
C. everything can be bought with money
D. only rich people have happiness
24. Which is the title of the passage?
A. Do Something Good to Others
B. Happy and Lucky
C. Happiness
D. Life and Success
You can be proud of yourselves, even if you can only make one or two of these green changes. The goal here is to limit carbon dioxide and other greenhouse gases, which are closely associated to the big problem of
25.What is the best title for the passage?
A. Strategies to Save Money
B. Ways to be Earth-Friendly

B. It will help to reduce a great deal of CO2.
C. It will save the amount of oil that runs your car for a mile.
D. It will be like planting 1.7 million acres of new trees.{2017利川市政府工作报告}.
27.Which strategies suggest recycling or reuse of things?
A. Strategies 1 & 3. B. Strategies 2 & 5.
C. Strategies 3 & 6. D. Strategies 4 & 5.
28.What benefits do these strategies have in common?
A. They all help reduce the use of energy like electricity.
B. They all cut down the amount of the use of paper.

D. They all aid to preserve our trees and forest.
If you are a fruit grower — or would like to become one —join in Apple Day to see what’s around. It’s called Apple Day but in fact it’s more like Apple Month. The day itself is on October 21, but since it has become popular, events now last through most of October around Britain.
Visiting an apple event is a good chance to see, and often taste, a wide variety(品种) of apples. To people who are used to the limited kinds of apples such as Golden Delicious and Royal Gala in supermarkets, it can be quite eye-opening to see some classical apples still in existence, such as Decio which was grown by the Romans. Although it doesn’t taste of anything special, it’s still worth a try.
There are also varieties developed to suit certain local conditions. One of the very best varieties for eating quality is Orleans Reinette, but you’ll need a warm, sheltered place with perfect soil to grow it, so it’s At the apple events, you can also meet expert growers and discuss which ones will best suit your conditions, and because these are family affairs, children are well entertained with apple-themed fun and games.
Apple days are being held at all sorts of places with an interest in fruit, including stately gardens and commercial orchards(果园). If you want to have a real orchard experience, visit the National Collection at Brogdale, near Faversham in Kent.
29.What can people do at the apple events?
A. Attend experts’ lectures.
B. Visit fruit-loving families.
C. Taste many kinds of apples.
D. Plant fruit trees in an orchard.
30.What can we learn about Decio?
A. It is a new variety.
B. It is rarely seen now.
C. It has a strange look.
D. It has a special taste.
31.What does the underlined phrase “a pipe dream” in Paragraph3 mean?
A. A clever idea. B. A selfish thought.
C. A great plan. D. A useless hope.
Philip Pullman spent a great deal of his childhood traveling abroad because both his father and stepfather were pilots in the Royal Air Force(皇家空军). As a child, he went on several long ocean voyages, and he lived in Africa and in Australia. “Before I was 11 I had been to eight different schools.”
“In Australia, I made a great discovery. TV hadn’t reached Australia yet, but everyone listened to the radio. I remember listening to gangster serials(黑帮剧), and cowboy serials, and best of all-----Superman! When I first saw a superman comic(连环漫画), it changed my life. I’d been reading books for a long time, but I’d never known comics before. Soon afterwards, I discovered Batman, too, whom I loved even more.”
Pullman started writing his first novel the day after he had finished his final exams at Oxford University. “ I discovered after about an hour that it was much harder than I’d expected. It still is! I found that the amount I could write comfortably every day was about three pages, so that’s what I’ve done ever since.”
Before he became a full-time writer, Pullman had been teaching for many years. “What I enjoyed most during that time was telling stories over and over, until I knew them as well as I knew my own life.” He had always loved telling stories---- as a schoolboy he had entertained his friends by reading stories to them, or by making up his own.
One day he got a letter that had arrived at his door even though the writer of the letter didn’t know his address. The envelope(信封) just said, “Philip Pullman, The Storyteller, Oxford.”
32.What can we learn about Pullman?
A. He was a pilot in the Royal Air Force.
