    Humans' invention of zero was vital for modern mathematics and science, but we're not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.

    Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.

    Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren't just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.

    In further experiments, the researchers showed that bees' understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators(捕食者)and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

(1)、According to the trials, the researchers have found that bees ________.
A、have the same intelligence as parrots and monkeys B、can count many numbers after being trained C、can identify the smaller number quickly D、understand the concept of zero
(2)、The researchers trained another group of bees to ________.
A、confirm the bees are able to identify the smaller number B、find the big difference between the two groups of bees C、prove the bees are interested in new things D、show the bees can be distinguished easily
(3)、What do the researchers suggest in further experiments?
A、Bees should be trained more. B、Numerical abilities could help predators find bees. C、Insects are better at understanding zero than animals. D、Animals may display a thorough grasp of the number zero.
(4)、What is the best the title for the text?
A、New Findings About Bees' Concept of Zero B、Experients on Bees' Numerical Skills C、Complex Trials About the Zero Club D、A Science Report of the Species of Bees

Passage 1

    The Information Highway is the road that links computer users to a large number of on-line services: the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowded road, and usually victims are some files, gone forever. Then, of course, there's Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don't trick yourself; he pays for that speeding.

Passage 2

    Want to know more about global warming and how you can help prevent it? Doctor Herman Friedman, who is considered a leading expert on the subject, will speak at Grayson Hall next Friday. Friedman studied environmental science at three well-known universities around the world before becoming a professor in the subject. He has also traveled around the world observing environmental concerns. The gradual bleaching (变白) of the Grate Barrier Reef, which came into the public eye in 2002, is his latest interest. Signed copies of his colorful book, which was published just last month, will be on sale after his talk.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home still hasn't sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $ 15,000 to $ 20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares to others on the market. Check out the finishes in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

    Why do you go to the library? For books, yes—but you like books because they tell stories You hope to get lost in a story or be transported into someone else's life. At one type of library you can do just that—even though there's not a single book.

    At a Human Library, instead of books, you can "borrow" people. People with unique life stories volunteer to be the "books." For a certain amount of time, you can ask them questions and listen to their stories, which are as fascinating as any you can find in a book. (If you attend, make sure to review the habits that make you a good listener.) Many of the stories have to do with some kind of depressing topic. You can speak with a refugee, a soldier suffering from PTSD (创伤后遗症), a homeless person and a woman living with HIV. The Human Library encourages people to take time to truly get to know and learn from someone they might otherwise make a snap judgement about. According to its website, the Human Library is "a place where difficult questions are expected, appreciated and answered."

    The Human Library Organization came to be in Copenhagen, Denmark in 2000. Romni Abergel and his colleagues hosted a four-day event during a major Northern European festival. After the success of this event, Abergel founded the Human Library Organization, hoping to raise awareness among youth about depression, which has been growing ever since.

    Though there a few permanent human libraries, most aren't place at all, but events. Though many do take place at physical libraries, you don't need a library card—anyone can come and be part of the experience. There have been human library events all over the globe, in universities and in pubs, from Chicago to Tunis to Edinburgh to San Antonio. Check out the organization's Facebook page to see when the Human Library might be arriving near you.

    Honey (蜂蜜) from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest (巢) and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.

    The honey guide does not actually like honey, but it does like the wax (蜂蜡) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.

    Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

阅读下列短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。

    I have been passionate about sewing and fashion design since I was 12. Two years ago, I designed and made a set of outfits from recyclable materials for a charity fashion show. Through this highly meaningful and profound experience, I became sensitized to the importance of protecting and preserving our environment when designing and making fashion items, resulting in my founding an organization to promote eco-friendly design and fashion.

    My interest has led me to research areas of fashion that have environmental implications. For example, some popular clothing stores have announced merchandizing policies designed to improve the environment. For those of us who are eco-conscious, it is incumbent upon us to evaluate whether such policies are just a marketing ploy, or represent genuine efforts to protect our environment.

    Three chain-stores, H&M, Urban Outfitters and Forever 21, have been promoting "green" items. After I examined their products, I have concluded that H&M and Urban Outfitters are truly helping the environment with their efforts, while Forever 21 seems to be using the 'go green' trend as a way to sell more products, rather than genuinely help the environment.

    Of these three stores, H&M has the most extensive eco-fashion plans. It is already well on its way to implementing its plans by increasingly blending organic cotton into their garments, as well as putting fully organic cotton items on the market. The store also belongs to the Organic Exchange Organization, which endorses growth of organic cotton. To reduce the substantial harm from non-organic cotton production, H&M is involved with the Better Cotton Initiative. Mindful of the adverse effects of climate change, the store aims to minimize transportation and energy usage. H&M labels their eco-friendly products with an official symbol, the Flower, to represent a production system that is less harmful than most traditional processes. Because of these actions and policies, H&M is already well on its way to making a difference on the environment.

    With its Urban Renewal brand, Urban Outfitter takes a different approach from H&M in promoting eco-friendly fashion. The brand features women's apparel made from strictly environmentally-friendly sources, such as vintage, dead stock, or surplus clothing. Urban Renewal produces fashionable garments, and embraces being eco-friendly through recycling.

    Unlike the other two stores above, Forever 21's eco-fashion efforts fall short; a cynic would say their message is downright misleading. It promotes the "'green" image, and yet many of their supposed eco-friendly products do not help the environment. For example, it sells a "Think Green Tote" that, according to the site, is meant "to send an environmentally friendly message". However, it is made of 100% non-organic cotton which is one of the most damaging fabrics to the environment, mostly because it requires greater chemical intervention compared to organic cotton. Also, the "I Love My Planet Tote" is supposed to "make a positive statement," but is also made of 100% cotton that is not organic. The only tote that is environmentally-friendly is the "H81 Organic Cotton Tote" from Forever 21's Heritage brand, made from 100% organic cotton. Now that Forever 21 has portrayed itself as being "green," it should start "walking the walk."
