In the winter vocation of 2008, I was fixed with a job. I worked as a(n) 21 at Mr Breen’s fruit shop. The fruit shop did good business. Most of the trade came from the housewives who lived in the neighborhood, 22_ he also had regular customers who arrived outside the shop in cars. Mr Breen 23 them all by names and they sometimes even had their order already made up, always 24 me to carry it out to their car. They were clearly longstanding customers, and I 25 they must have stayed faithful to him because he had promised to sell good quality fruits. He had a way with them---- I had to 26 that. He called every woman “madam” for a start, 27 those who clearly were not, but when he said it, it did not sound like flattery(恭维). It just sounded 28 in an old-fashioned way. He was a great chatter 29 . If he did not know them, he would greet them with a few 30 about the weather, 31 he did, he would ask about their families or make 32 , always cutting his cloth 33 his customers. Whatever their bills came to, he 34 gave them back the few odd pence(零钱), and I was sure they thought he was very generous. But I thought he was the opposite. He never threw anything away. He was always looking for 35 for nothing.

A Love Note To My Mom
When I was a little girl, would often accompany you as you modeled for fashion photographers. It was years later that finally understood what role modeling 1 in your life. Little did I known you were 2 every penny you earned to go to 3  school.
I cannot thank you enough for 4 you told me one autumn afternoon when I was nine. After finishing my homework. I wanted into the dining where you were buried 5   piles of law books. I was 6  .Why were you doing what I do—memorizing textbooks and studying for 7  ?When you said you were in law school, I was more puzzled. I didn’t known. Moms 8  be lawyers too. You smiled and said,“In life, you can do anything you want to do.”
As young as I was ,that statement kept   9  in my ears. I watched as you faced the   10  of completing your studies, staring companies with Dad, while still being a   11  and a Mom if five kids. I was exhausted just watching you   12  .With your words of wisdom in my   13  mind, I suddenly felt unlimited freedom to dream. My whole world   14  .I set out to live my life filled with   15 ,seeing endless possibilities for personal and professional achievements.
Your words became my motto. I   16  found myself in the unique position of being either the first (woman doctor in Maryland Rotary) 17   one of the few women (chief medical reporters) in my field. I gained strength every time I said , “Yes, I’ll try that.”
Encouraged by your   18  , I have forged ahead (毅然前行) with my life’s journey, less afraid to make mistakes, and   19 meeting each challenge. You did it, and now I’m   20  it. Sorry, got to run. So much to do, so many dreams to live.

A．found

Animals seem to have the sense (本能) to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant（香的） flavor (味道) was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．
In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria（自助） feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．
So, in selecting food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-established（长期养成的）habits．Some people eat foxes, dogs and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．
53．The expression “the habit” in paragraph 1 refers to drinking water which _______．
A. has no smell B. is tasteless C. has vitamins D. is flavored (有味道的)
小题1:According to the passage, adults eating habits differ from those of babies because _______．

A．adults know better than babies what kind of food are good for their health

B．adults usually cannot resist (抵制) the temptation (诱惑) of various delicious foods

C．adults' eating habits are closely related to the social and cultural customs

D．adults have more choices of food than babies in eating patterns

小题2:The author implied in the passage that most of us _______．

A．eat a balanced diet

B．choose the food that is of nutrition

C．have the habits influenced by the surroundings

D．like to eat the food with a fragrant flavor．

小题3:As far as their eating habits are concerned, babies and rats are similar in that _______．

A．both have the wisdom to choose a balanced diet

B．both prefer flavored food and drink

C．both have the same eating patterns

D．both develop a taste for the same kinds of flavors

Air pollution is damaging 60% of Europe’s prime wildlife sites in meadows, forests and bushes, according to a new report.
A team of EU scientists said nitrogen emissions(氮排放) from cars, factories and farming were threatening biodiversity. It’s the second report this week warning of the on-going risks and threats linked to nitrogen pollution.
Nitrogen in the atmosphere is harmless in its inert(惰性的) state, but the report says reactive forms of nitrogen, largely produced by human activity, can be a menace to the natural world.
Emissions mostly come from vehicle exhausts(排气), factories, artificial fertilizers(肥料) and animal waste from intensive farming. The reactive nitrogen they emit to the air disrupts the environment in two ways: It can make acidic soils too acidic to support their previous mix of species. But primarily, because nitrogen is a fertilizer, it favors wild plants that can maximize the use of nitrogen to help them grow.
In effect, some of the nitrogen spread to fertilize crops is carried in the atmosphere to fertilize weeds, possibly a great distance from where the chemicals were first applied.
The effects of fertilization and acidification favor common aggressive species like grasses, brambles and nettles. They harm more delicate species like mosses(苔藓), and insect-eating sundew plants.
The report said 60% of wildlife sites were now receiving a critical load of reactive nitrogen. The report’s lead author, Dr Kevin Hicks from the University of York’s Stockholm Environment Institute (SEI), told BBC News that England’s Peak District had a definitely low range of species as a result of the reactive nitrogen that fell on the area.
“Nitrogen creates a rather big problem that seems to me to have been given too little attention,” he said. “Governments are responsible for protecting areas like this, but they are clearly failing.”
He said more research was needed to understand the knock-on effects for creatures from the changes in vegetation accidentally caused by emissions from cars, industry and farms.
At the conference, the representatives agreed “The Edinburgh Declaration on Reactive Nitrogen”. The document highlights the importance of reducing reactive nitrogen emissions to the environment, adding that the benefits of reducing nitrogen outweigh the costs of taking action.
小题1:The underlined word “menace” is used to express that the reactive nitrogen, largely produced by human activity can be ___________.

小题2: We can infer from the passage that _________.

A．it’s harmless to have reactive nitrogen existing in the atmosphere

B．reactive nitrogen emissions help aggressive species less than crops

C．the harm to those delicate species has a negative impact on biodiversity

D．reactive nitrogen can fertilize soils and keep their biodiversity

小题3: The team of EU scientists released the second report of nitrogen emissions this week when __________.

A．no action was taken to stop nitrogen emission

B．governments were willing to protect areas harmed by nitrogen

C．“The Edinburgh Declaration on Reactive Nitrogen” was agreed

D．nitrogen emissions were threatening wildlife sites’ biodiversity

小题4: Which of the following would be the best title for the passage?

A．Keeping Away From Nitrogen Emissions	B．Stopping Nitrogen Emissions
C．Air Pollution Damaging Europe’s Wildlife	D．Saving Europe’s Wildlife

In 2006, a large number of new Internet sites became popular around the world. Some of these are for communication, others for entertainment.
The blog is one form of communication that increased in popularity. Through these personal websites, people can share their lives, ideas and opinions on the Internet. People of all ages have their own blogs. For young people, they are a way to show their writing and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas with other teachers’, as well as experiences and concerns about their work.
YouTube is another Internet site that became more popular last year. This website lets anyone create, share and watch short videos. These include videos of people singing or dancing, or animals doing funny things. Three young men created YouTube almost two years ago as a personal video sharing service. They recently sold it to Google for more than one and a half billion dollars.
Games and entertainment also became a l

arger part of the Internet last year. One Internet social site is called Second Life. It is an online world in which computer u

sers create a new self and live a different life. They get married, build homes, operate businesses, buy and sell goods, work, play and attend school.
People also take part in fantasy sports leagues with the help of the Internet. A fantasy sport is a game in which each member of a group acts as the owner of a team. Each owner creates a team of real-life professional players to compete against other teams in the league. More than fifteen million American adults play fantasy sports. The industry earns more than one billion dollars each year from publications, memberships and other costs.
小题1:The passage is mainly about __________.

B．some new ways for people to communicate or have fun on the Internet

C．one online game called Second Life

D．the high price of playing online

小题2:Who is the owner of YouTube now?

小题3: Whom does the underlined word “they” in Paragraph 4 refer to?

A．The people who are interested in blogs.

B．The people who play games on YouTube.

gers play fantasy sports.

C．Second Life helps people get married, buy and sell goods, work, play and attend school in real life.

D．Fantasy sports, a game in which each member of a group acts as the owner of a team, is very popular around the world.

What does “getting along” with your teacher mean? “Getting along” means that both you and your teacher have a way of communicating and getting what you need from the relationship. In your teacher’s opinion, he or she wants to make sure that you are paying attention, being polite, and trying your best to learn. In your opinion, you want a teacher who is respectful to you, answers your questions, and tries to help you learn. You can get along and learn without being friends with your teacher, although it’s nice if that happens.
In every school, kids will say that some teachers are mean or strict, but don’t judge a teacher until you are in his or her class and can see for yourself. A strict teacher may be someone who feels strong about getting his or her job done — teaching you the subject you are supposed to learn. It’s also important to remember that making mistakes is a part of learning. By pointing out your mistakes and helping you correct them, a teacher is teaching you. Remember, in most cases, your teacher is on your side.
Even if a teacher isn’t your favorite, you can still have a successful relationship, especially if you carry out your responsibilities as a student. Here are some of those responsibilities:
●Attend class ready to learn. Be prepared for class with the right pencils and books.
●Listen carefully when your teacher is talking.
●Do your best, whether it’s classroom work, homework, or a test.
小题1:The main idea of this passage is about _______.

A．learning from your teacher

B．making friends with your teacher

C．getting along with your teacher

D．understanding your teacher

小题2: If you get along with your teacher, _______.

A．your teacher will have to answer your questions

B．both of you will benefit from the relationship

C．your teacher will have to be respectful to you

D．you will have to try your best to learn

小题3:What does the underlined sentence in the second paragraph mean?

A．Your teacher is teaching you to learn the subjects.

B．The teacher has the responsibility to be strict with students.

C．Pointing out your mistakes is also a way for a teacher to teach.

D．The teacher is there to help you.

小题4: According to the passage, which of the following is NOT the responsibility of a student?

A．Learning by making mistakes.	B．Attending class ready to learn.
C．Listening to your teacher carefully.	D．Trying your best to learn.

These days no car show is complete without an electric car, and the 2011 North American International Auto Show in Detroit, US, which ran from January 10 to 23, was no exception.
Among the fully electric vehicles on display were the Ford Focus Electric and the Honda Fit EV. BMW and Volvo also had prominent displays at the show, proving that they can produce practical, yet spacious family-oriented electric cars.
Industry insiders at the show claimed that more efficient batteries, improved performance and greater consumer acceptance could make 2011 the “year of el

ectric car”.
It’s long been clear that electric cars score heavily for convenience. They are, for instance, much easier to maintain than gasoline-powered cars. When the battery runs out, you simply replace it or recharge it, just like you would for a cell phone or a laptop.
This is also a much cheaper method than filling your tank with gasoline. Better yet, electric cars don’t emit exhaust fumes. As a result, they don’t produce environmentally damaging greenhouse gases.
It appears that improved technology is making electric cars and their maintenance much more user-friendly. So, what are the obstacles which are preventing electric cars from becoming popular and fashionable?
Home charging for electric cars could be extremely convenient for users. However, it is also a potential obstacle. For a start, installing charging stations in owners’ homes will be a challenge, particularly for those who have to park several blocks away from their homes.
Also, charging the car’s battery still takes quite a long time. It may be some time yet before you can recharge an electric car in the same time as you can refill your gas tank.
Another problem is that many electric vehicles have limited ranges that may only allow for journeys of 50 miles (80 km) or less between charges. In cases where a driver wishes to charge the car primarily at home (perhaps overnight), this limits their daily driving to the range of their vehicle.
This may be one reason why hybrid cars are now becoming more popular. A hybrid car has more than one energy source, usually a traditional gasoline fuel tank and an electric battery. It’s like a more practical version of an electric car: It’s greener than a conventional vehicle, with fewer CO2 emissions, yet it also doubles as a conventional vehicle.
“I would say that hybrid is a transition to fully electronic,” Road and Track magazine editor Richard Horman told Detroit News during the show. “The trend is for lighter, smarter, more economical cars. Of course

, electronic vehicles are meant to be that way.”
This sounds promising, particularly in light of the fact that the show featured more electric cars from big manufacturers than ever before.
However, it seems that the technology associated with electric cars is not yet able to fully meet people’s expectations. Don’t expect gasoline-powered cars to disappear from roads just yet.
小题1: What made electric cars more convenient?

A．Easier maintenance.	B．High scores on the show.
C．Practicality and large space.	D．Much lower prices.

小题2: Which of the following could NOT act as a potential obstacle of electric cars?

A．It is rough work to install charging stations at home.

B．It is time-consuming to charge the batteries.

C．The ranges between charges are limited.

D．There’s no need to fill the tank with petrol.

小题3:In Paragraph 10, the underlined word “hybrid” is probably closest in meaning to ________.

小题4:The writer’s purpose in writing this passage is to_________.

A．introduce the 2011 Auto Show in US	B．get readers informed of electric cars
C．comment on different types of cars	D．advertise for electric cars

When you have a question about something, where do you go? For many people the answer is simple as they can go online to a search engine like Google or Yahoo. But what about people in rural or underdeveloped areas who may have no way to get on the Internet?
A business and international development professor in California, Rose Shuman, found an answer for them: Question Box. Question Box is a service that provid

es answers---free of charge--- for people who cannot search the Internet directly. The users of Questions Box might be those who might not be

able to read, or simply have no access to the Internet.
Question Box began three years ago in India. People used a metal call box with a push-to-talk button to connect a live operator. Rose Schuman explained,” You just need to push a big green button on the box which will connect you directly to our operators who are sitting in front of computers, and speak your language. You can ask them any sort of question you want, and they’ll look it up in English or in Hindi, or whatever the main language is, and translate the answer back for you.”
The service is currently offered in two villages. The latest version of the box uses mobile phone technology, and solar panels in case the electrical power fails. Rose Shuman says the aim was to make the box as easy as possible for users, “It is very efficient (效率高的). Rather than try to bring a lot of difficulties to them and expect them to spend a lot of time to learn how to use the Internet, the idea was to make a technology that even Grandma could use.”
In April 2009, Question Box was introduced to Uganda. Forty community workers with mobile phones connected villagers to call center operators in Kampala. The community workers went around telling people about the service. They wore T-shirts that said “Ask me.” But Internet service in Uganda proved slow and undependable. So Question Box teamed up with a local technology company to store information on a local server. That way, the researchers in Kampala could quickly search the database for answers.
小题1: The best title for the passage is __________.

A．Question Box ----taking the place of the Internet

B．Needing an answer? ----asking Question Box

C．Question Box ----A great invention in the world

D．Rose Shuman-----

A professor helping the poor

小题2: In Rose Schuman’s opinion, the greatest advantage of Question Box is that______.

A．It is the most advanced in the world

B．It is more convenient to carry.

C．It is much easier to use

D．it saves much more energy

小题3:The underlined word “them” in the fourth paragraph refers to______.

A．the users	B．the operators
C．the researchers	D．Question Box workers

小题4:What can we know from the passage?

A．Question Box costs the users much less than the Internet.

B．Question Box operators can look for information in any language.

C．Question Box is more efficient in solving problems in underdeveloped areas.

D．Question Box can work without the help of the Internet in Uganda.
