第一节（共15小题；每小题2分，满分30分）

阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

[A]

He has a bright idea.

Avery Hairston is lighting up people’s lives. The 15-year-old from New York City created an organization called RelightNY. It helps people who have difficulty in paying their electricity bills by giving them special light bulbs (灯泡), which cut long-term electricity costs. They are also better for the environment than common bulbs. “People who can afford the bulbs, which are a bit expensive,should buy them,” Avery insists.

He is very interested in recycling (回收再利用).

Eli Kahn, 15, started Cartridges for a Cure to raise money for children’s cancer (癌症) research by recycling empty ink cartridges (墨盒). Eli has raised $82,000 for Johns Hopkins Ch ildren’s Center.“With a little time and work, anything can get bigger,” Eli says.

She makes water safe to drink.

Kelydra Welcker, 17, has been trying her best to make drinking water safer. She invented an easy way to get the chemical C8 out of her West Vi rginia town’s water supply (供应). C8 went into the water from a nearby industrial factory. “Clean water should be a given,” Kelydra explains. “We all should have it.”

She tries to stop deforestation.

Wangari Maathai, from Kenya, Africa, has been working for many years to save the forests. In 1977, she started a movement in Kenya to help stop deforestation (the cutting or burning down of all the trees). The program has planted more than 30 million trees in Africa. Her work brought her the Nobel Peace Prize in 2004. In 2006, she helped start the Billion Tree Campaign. The United Nations program encouraged people to plant trees in their neighborhood, with the goal of planting one billion trees

worldwide that year. So many people who wanted to go green joined the program, and more than nine million trees have been planted. Maathai says, “This is something anybody can do.”

21. What can we learn about RelightNY?

A. It helps the poor save money.

B. It is a United Nations program.

C. It raises money for sick children.

D. It provides people with free bulbs.

22. Who won the Nobel Peace Prize in 2004?

[B]

I’ve al ways been interested in computers and technology, and I made a few apps (应用程序) for the iPhone, iPod touch, and iPad. I’d like to share a couple with you today. My first app is “Earth Fortune”. My favorite and most successful app is “Bustin Jieber”— which is a Justin Bieber whack-a-mole (打地鼠游戏). I created it because a lot of people at school disliked the pop star a little bit, so I decided to make the app. I released (发布) it on December 21, 2010.

A lot of people asked me, how did I make these? A lot of time s it’s because the person who asked the question wants to make an app also. Where do you go to find out how to make an app? Well, this is how I got close to it, and this is what I did.

First of all, I’d already been programming in many programming language s to get the basics down, such as Python, C, Java, etc. And then Apple released the iPhone

with the software development kit (软件开发工具包) — a set of tools for creating and programming an iPhone app. This opened up a whole new world of possibilities for me, and after playing with the kit a little bit, I made a couple of test apps. I persuaded my parents to pay 99 dollars to be able to put my apps on the App Store. They agreed, and now I have apps on the App Store.

I’ve gotten a lot of creative ideas from Steve Jobs, and I’ve started an app club at school with the help of my teacher. Any student at my school can come and learn how to design an app.

I’d like to finish up by saying what I’d like to do in the future. I’m working with a third party company to make an app. My next goal is to get into Android programming and development, continue my app club, and find other ways for students to share knowledge with others.

That’s all. Thank you!

24. What can we learn about Bustin Jieber?

A. It is the author’s first app for the iPhone.

B. It was released at the beginning of 2010.

C. It is popular with Justin Bieber fans.

D. It is a whack-a-mole game.

25. What allowed the author possibilities to program?

A. His teacher’s guidance.

B. Test apps on the App Store.

C. Apple’s software development kit.

D. The Java programming language.

26. What did the author do after he finished his test apps?

A. He bought an iPhone.

B. He met with Steve Jobs.

C. He sold them to the App Store.

D. He asked his parents for support.

27. What’s the author’s future plan?

A. To set up an app club.

B. To design an Android app.

C. To put his apps on the App Store.

D. To share his apps with others for free.

The Center at Palos Park is planning to offer a nice Barn Dance (谷仓舞会) for those who enjoy modern Western dancing but don’t want to lose the old-fashioned feel of the popular fall activity.

Line dancing has taken the place of square dancing this year, said Mark Walker, The Center’s director of development, and nobody ne eds to worry about keeping up.

“It’s easy and fun and there’ll be clear directions from the workers and some other dancers,” Walker said.

The 13th Barn Dance takes place from 5 to 8:30 p.m. Sept. 9 at The Center’s Children’s Farm, Palos Park.

A wooden floor made for dancing will take the place of part of the dirt floor in the large riding area of the barn, where hay bales (干草捆) are used for sitting and Italian lights are hung overhead — just the right touches to recreate an old-fashioned harvest (收获) dance of past years.

Dancing is only one of the activities. There’s more to see and do.

“You don’t even have to dance at all,”Walker said. “If you’re not into dancing, it’s fun just to come anyway.”

Tours of the farm and its many lovely animals continue until 7 p.m. Traditional harvest-time hayrack (有装草架的大车) rides will take guests on a half-mile journey around the working farm.

“The sun will be setting during most of that time. The light will be golden, and it’s really just great to enjoy ...” he said.

If all goes well with the weather, rides continue throughout the evening, Walker said. He said the outdoor activities won’t be hampered by a few raindrops. It will take a heavy rain to drive everyone inside, where the fun will continue.

“Dress for the weather,” Walker suggested, “but it is on, rain or shine ... because there’s a lot to do in the riding area.”

All activities are included in the $10 ticket price for children and adults. Food and drink will be provided but visitors will have to pay a little more.

28. What’s special about this year’s Barn Dance?

A. It wants to attract more children.

B. It will be held in a different season.

C. It will give up old-fashioned line dancing.

D. It offers modern dancing in a traditional environment.

29. What will the dancing place be like?

A. It will have hay seats.

B. It will have a dirt floor.

C. It will have a wooden door.

D. It will have Italian floor lights.

30. What can those who are uninterested in dancing do?

A. Feed the animals.

B. Help on the farm.

C. Watch the sunset.

D. Drive hayracks.

31. What does the underlined word “hampered” probably mean?

A. Stopped.

B. Developed.

C. Protected.

D. Decided.

[D]

Sometimes people make history. George Washington became the first president of the United States and made history. Sometimes wars make history. The two World Wars are examples. Sometimes nature even becomes part of history. Shaking earthquakes are recorded in history books.

Thirteen years ago, nature caused just such a history-making event. In September 2005, Hurricane Katrina came ashore in New Orleans, Louisiana. The deadly storm flooded (淹没) New Orleans. Before Katrina, no other big American city had ever flooded in the history of the country. This natural disaster caused great harm and death.

New Orleans is located (位于) below sea level. This location places it at great risk. Levees were built to protect New Orleans from the ocean. (A levee is like a wall between the city and the ocean.) When Hurricane Katrina came ashore, water moved over the levees into the city. Flooding made it necessary for everyone to leave the city. Before Katrina, Creole food (a special kind of cooking only in Louisiana) filled the air with delicious smells. The sound of jazz music traveled through the streets. Now the city has to return to its former glory (辉煌).

Before Katrina, the U.S. government had never made everyone leave a city. People in New Orleans had to find shelter quickly. Some had to stay at the Superdome Sports Center. Some rode on buses to other towns. Thousands drove their cars to get away from the storm. The roads and shelters filled up fast.

The lesson learned from Katrina was that cities must be better prepared for big storms and other terrible disasters caused by nature. Being prepared might have kept more people safe. Hurricane Katrina is one of the history-making events that will be remembered forever. Today, history is still being made that will shape the future.

32. What does the author tell us about New Orleans?

A. It was built above sea level.

B. It had few jazz musicians after Katrina.

C. It created a new way to cook after Katrina.

D. It was the first U.S. city that had been flooded.

33. What can we say about the levees?

A. They were almost useless for fighting Katrina.

B. They helped people leave New Orleans quickly.

C. They made New Orleans a special American city.

D. They should be built to match the size of New Orleans.

34. What might the author advise city governments to do?

A. Put up more shelters in the city.

B. Build more levees around the city.

C. Teach people how to avoid floods.

D. Try to get ready for natural disasters.

35. What is the best title for the text?

A. Katrina makes history

B. Floods shape Louisiana

C. Storms are dangerous

D. History must be remembered

The Grand Canyon (大峡谷) is a large river canyon in Arizona. It is over 220 miles long and over a mile deep in some places. 36 The canyon is considered one of the Seven Natural Wonders of the World.

Over millions of years, the Colorado River cut through rocks as it passed through the area. 37 Now, the canyon is surrounded (围绕) by high walls on either side, while the river continues to move at the bottom of the canyon.

Besides its large size, the Grand Canyon is also known for its beautiful colors. The canyon is made of layers (层) of rock, and each layer of rock has a different depth and color. Geologists (地质学家) have found almost 40 different layers of rock.

The Grand Canyon is home to different kinds of plants and animals. 38 Many kinds of animals also live there, including the bald eagle, bobcats, bats and Gila monsters.

American Indians have lived in the area for around 3,000 years. Spanish explorers (探险家) first discovered the area in 1540. Later, other Spanish explorers returned in 1776. 39

[A]

A recent survey has shown that the busiest shopping street in the world is not in London, New York, or Paris, but in Warsaw (capital city of Poland). It’s called Nowy ?wiat, which means New World. About 14,000 Poles walk down this main street every hour.

It is a lovely place to shop. The street is very wide. There are statues, palaces, attractive (有吸引力的) town houses, high-class cafés and restaurants. The buildings aren’t too tall. They look old, but in fact the whole city was rebuilt after World War II. There aren’t any billboards (广告牌), loud music, or many tourists. People think that Polish shops have nothing to sell, so tourists don’t come shopping here. The world does n’t know about this good place for shoppers— yet.

It is now possible to buy almost everything in Warsaw. There are many shops from the West. However, Nowy ?wiat has a lot of small shops and specialist shops. It hasn’t got the huge department stores that s ell the same things everywhere.

If you want an excellent hand-made suit, Nowy ?wiat is the place to go. It isn’t cheap. You will pay up to ￡1,000. For beautiful French baby clothes, go to Petit Bateau. You will pay ￡50 for a pair of blue jeans for a baby. A dress for a baby girl is about ￡90. At Desa, a famous antique (古董) shop, a desk costs ￡5,000.

Not everything is expensive. At the shop Pantera you can buy leather (皮革) goods — handbags, purses, coats, and belts. Cepelia is famous for folk art. There are also book shops and record shops. And there are a lot of small shops that sell clothes that aren’t too expensive. If you’re tired, stop at CaféBlikle. You’ll find a lively environment, and a lot of well-known Poles.

It is possible to travel the world and find the same things for sale in every country. But Warsaw is different because its shops are unique (独一无二的) —and they’re in Nowy ?wiat.

1. In outsiders’ eyes, Nowy ?wiat is _____.

A. a tourist attraction

B. a perfect place for shoppers

C. not worth visiting

D. no different from any shopping street

2. What’s so special about the shops in Nowy ?wiat?

A. Th ey’re all hidden in ancient buildings.

B. Everything sold there is very expensive.

C. Most goods sold there are hand-made.

D. They sell goods you can’t buy anywhere else.

3. Where can you most probably meet famous Poles?

A. Cepelia.

B. Pantera.

C. Café Blikle.

D. Petit Bateau.

4. What does the text mainly introduce?

A. The capital city of Poland.

B. The most famous sho p in Nowy ?wiat.

C. The busiest shopping street in the world.

D. The most ancient town house in Warsaw.

[B]

They often have advice for some of the world’s top referees (裁判) and international football managers. They have opinions on most of the world’s major football players. They can remember more scores than TV football commentators (评

论员). And they probably haven’t kicked a ball since primary school. Yes, it’s that strange beast, the armchair football fan. In the same way that the back seat driver gives instructions to the driver in the front seat but may not even have a driving license (驾照), the armchair football fan knows how to win every match but was probably the last person to be chosen for the school football team.

My brother is a very good example. Like all his friends, Ross never leaves the house without his football shirt, tracksuit trousers and trainers. Looking at him, you might think he was on his way to football training at the sports center. But no, the only exercise Ross does is when he has to run for the bus in the morning. He often says that he has no head for remembering facts and isn’t interested in history and yet he can remember that Aberdeen beat Lech Poznan 3-0 in the 1983 European Cup, twelve years before he was even born.

Is it just a harmless obsession (着迷)? In most cases, it probably is. I’m certainly not too worried about Ross at the moment. But we mustn’t forget that there’s also a more worrying side to being an armchair fan. Doctors say that you should exercise for at least half an hour, three times a week but in fact, armchair sports fans are some of the unhealthiest people around and many don’t like to exercise at all. What’s more, watching sport can make you ill. To our surprise, doctors at the Royal Infirmary of Edinburgh had to treat more than 150 patients who got ill while watching football at home during the 2012 World Cup. Problems included heart attacks, temporary (短暂性的) deafness and even mental problems. Similarly, researchers in the Netherlands found that the number of men who had heart attacks went up fifty percent on the day of an international football match. So it seems that although sport is goo d for us, being sports mad probably isn’t.

5. According to the author, why is an armchair football fan similar to a back seat driver?

A. Both are very talkative.

B. Both are very big-headed.

C. Both spend a lot of time sitting.

D. Both usually have more knowledge than skill.

6. What can we learn about the author’s brother?

A. He is very good at math.

B. He has difficulty remembering.

C. He likes to wear sporty clothes.

D. He wants to become a football player.

7. When it comes to armchair football fans, what does the author care more about?

A. Their health.

B. Their thoughts.

C. Their behavior.

D. Their knowledge.

8. In the last paragraph, what does the author probably advise armchair football fans to do?

A. Speak less and play more.

B. Watch games reasonably.

C. Listen to TV commentators patiently.

D. Take some exercise before watching games.

One possible version：

This afternoon all the teachers and students in our school attended a lecture about how to survive in an earthquake. The lecture was given by Professor Li from a famous university in the school hall.

In the lecture, Professor Li told us the signs of a coming earthquake and dos and don’ts during a nd after an earthquake. We all listened and took notes carefully. After the lecture, a video about earthquakes was shown.

We all realized how important it is to know how to stay safe during an earthquake, because even a little knowledge can increase our chances of surviving an earthquake or any other type of disaster.
