Humans aren’t the only ones getting a buzz from coffee．Caffeine can improve memory among honeybees and lead to better pollination(授粉)．According to a recent study published in the journal Science．
The study was conducted by a team of researchers at Newcastle University in the United Kingdom．They found that the nectar(花蜜)of some flowers，such as those from grapefruit and lemon plants，as well as certain coffee flowers，contains low doses of caffeine．To get bees to feed on these flowers，the team trained the insects to associate food with the smell of the flowers．They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine．After 24 hours，the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants．
Professor Geraldine Wright led the researchers．“Remembering floral traits(花部特征)is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are，”Wright said in a statement．
Improved memory led to the better pollination．That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate．This also suggests that caffeine plays a role in improving the bees’ability to search for food．
Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals．“The change is similar to that produced by caffeine in neurons(神经元)associated with learning and memory in the rat brain，”Wright said．
Bee populations have declining since 2007．The dramatic drop in the insects’numbers has serious effects for ecosystems and the farming industry．Bees are needed in the reproduction of crops and spreading wild flower species．Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers．Which of the following is mentioned in the passage?
| A．Caffeine has no effect on the rat brain． |
| B． Bee population has been increasing． |
| C．The nectar of lemon plants contains caffeine． |
| D．Bees dislike nectar from sweetened flowers． |
After reading the passage，John，who works in the farming industry, will probably feel ____________.
| A．annoyed | B．angry | C．nervous | D．excited |
Which of the following relationship is correct according to the passage?
| A．improved memory—caffeine nectar—better pollination |
| B．caffeine nectar—improved memory—better pollination |
| C．improved memory—better pollination—caffeine nectar |
| D．caffeine nectar—better pollination—improved memory |
What section of a newspaper may this passage be taken from?
| A．Science | B．Education |
| C．Culture | D．Sports |
Renata Di Pietro was studying to be an opera singer. But at 23, while on a music scholarship at the University of Iowa in 1976, her sight began to fail. Soon, it became increasingly difficult to read scores and pick up hand signals from conductors, and the gifted singer was forced to drop out.
After moving to Cleveland, Georgia in 2005, Di Pietro relied on guide dogs to get around. Over the years, she became depressed when she’d lose one of the dogs, who had become her best friend, to old age or death. “It’s very painful, because you love each one,” she says.
In 2009, Di Pietro was intrigued by information from a friend that miniature horses typically live for at least 30 years and make calm and strong guides. She started with a male horse, but he was too hard to control. Angel came next, a mini white female horse Di Pietro has mostly trained herself. “Horses have the ability to avoid the things in the way,” she says. “If I am about to run into something, she slides her body in front of me.”
Di Pietro, now 59, has taught her guide horse to make some sounds with her hoof (马蹄)when she comes to stairs. “Angel can find a chair and locate the nearest door for me,” Di Pietro says. Currently, she’s training Angel to pull her wheelchair and to fetch.
Despite her disability, Di Pietro still sings, performing with her husband, musician Carl Hummer, at special events. Angel is always by her side. “I fight a battle every day to take courage to engage the world,” Di Pietro says. “Angel is my warhorse. We fight that battle together.”Why did Di Pietro have to give up her studying in the university?
| A．She disliked her major in music. |
| B．She failed to get high scores. |
| C．She couldn’t understand hand signals from conductors. |
| D．She found it difficult to see things clearly. |
What does the underlined word “intrigued” in Paragraph 3 probably mean?
| A．Puzzled. | B．Interested. | C．Satisfied. | D．Frightened. |
Angel can do a lot of things for Di Pietro now EXCEPT_________.
| A．supporting her in case of her falling |
| B．helping her find a chair to sit on |
| C．keeping her company every day |
| D．fighting with her against others |
Which of the following can best describe the author?

March 22, 2011---Most restaurants in the United States offer their customers a glass of tap water at no charge with their meal, but this week many restaurants are asking dinners to pay a dollar, or more, for a glass of water. Cards on their tables explain that this small amount helps bring clean water to children around the world. It’s called the UNICEF Tap Project.
“UNICEF’s Tap Project is really all about bringing attention to the fact that over 900 million people around the globe do not have access to good, clean, healthy drinking water,” says Cary Stem, who heads the US Fund for UNICEF. She adds that water-borne illness is the second-highest cause of preventable childhood death in the world.
“Each and every day approximately 4,100 children die just because they don’t have that access - 4,100 every single day.”
The public service campaign encourages people to help change that statistic with a simple, affordable action: paying a dollar to get a glass of tap water at a restaurant.
“One dollar buys enough good, clean water for a child for 40 days,” Stem says.
“The tap project has expanded since it began five years ago with 300 restaurants in New York City. This year, Stem says, about 3,000 restaurants across the country are participating in the campaign. We raised about $2.5 million over the last five years of this campaign,” says Stem. “Last year, we raised over $1 million for the first time. This year we’re hoping to top that.”
Stem credits the continued success of the campaign to an army of volunteers who support the tap project and raise money in their communities.
The UNICEF Tap Project is promoting its efforts with a simple motto: when you take water, give water. Currently, UNICEF works in more than 100 countries around the world to improve access to safe water and sanitation facilities in schools and communities.
Stem hopes that, by participating in the project, more Americans will realize that what they often take for granted is a precious and scarce resource in many other parts of the world.Restaurants began to charge for tap water to _______.
| A．increase their profit |
| B．urge customers to save water |
| C．raise people’s awareness of the world water problem |
| D．collect money for those without access to safe water |

| C．is hoping to collect $2.5 million this year |
| D．provides help for 1,000 countries in the world |

| A．the Tap Project began in 2006 |
| B．America suffers a serious problem |
| C．4,100 children die of water pollution every year |

When you don’t have anything planned for the day or it’s rainy outside and your children are stuck in the house, why not sit around and tell them riddles? Telling riddles will make your family laugh and sometimes even scratch their heads, trying to figure out what the answer is.
Riddles have been a pastime for centuries. Not only have riddles been something for passing the time, but they have also been used to pass on secret information during the Second World War. Even the ancient Greeks used riddles. They would tell riddles at parties and whoever was the first to get them right would receive prize.
Most riddles use words that have double meanings or share the same sound like “hear” and “here”. So in order to get the riddle, you will have to do some creative thinking and think of all the possibilities of different words. The difficulty of figuring out the riddle is based on the riddle itself. The riddle has to provide you with enough clues to come to the right answer, but that doesn’t mean that the clues have to be easy.
If you are looking to tell riddles but don’t know any, you can look online and you will find a large number of sites that will have hundreds of different riddles to choose from. If you would like to look somewhere else then you could look at your local bookstore, where you will be able to find many different books with thousands of riddles to choose from. You can even find websites and books that will tell you how to write your own riddles.
After you have found some resources that have different riddles, you will need to read through them to find the right ones for you and your family: You will also need to make sure that your kids will have a chance to figure out the answers. So take your time and choose the right family riddles to tell.What is the author’s main purpose in writing the text?

It can be hard to meet people from another culture. From the beginning, people may send the wrong signal（信号）. Or they may pay no attention to signals from another person who is trying to develop a relationship.
Different cultures emphasize （强调）the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in “small talk”, usually over a glass of tea, before they do any job. In many European countries--like the UK or France—people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.
Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.
Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.
People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment（多元文化环境）will offer a wonderful chance for us to learn from each other.In some countries, eating together at restaurants may make it easier for people to ________.
| A．keep each other company | B．share the same Culture |
| C．get to know each other | D．develop closer relations |

| A．By sharing different ways of life. |
| B．By recognizing different values. |

What would be the best title for the text?
| A．Multicultural Environment. | B．How to Understand Each Other. |
