The red crab lives on Christmas Island in the Indian Ocean and has been found nowhere else in the world. But on its homeland it is a very significant species -- some 120 million individuals cover the rain forest floor and play a major role in determining the structure of the ecosystem. These large crabs are active during the day but prefer to stay in the shade and can die in the heat of direct sunlight. They feed on fallen leaves, seeds, fruits and flowers, recycling nutrients and helping to determine the spread and composition of native plants. Most of the year the red crabs live in the holes they dig throughout the forest. During the dry season they hide in these shelters to keep their body wet and remain there for two to three months. But when wet season returns in October or November they begin a legendary mass migration to their seaside breeding grounds, moving in color1ful wave that wash over all obstacles like roads (including special passages and some closed roads built for the red crab) and even seaside cliffs. The annual migration is also closely tied to the lunar schedule. The crabs arrive at the coast and breed at such a time that the females can produce eggs and develop them in caves for a dozen or so days before carrying them into the sea exactly when high tide turns between the last quarter and new moon. During this period sea level on the beaches varies the least and offers an easier approach, which is so important that if the weather delays the migration crabs will put off laying eggs until the next lunar month. Red crab eggs grow right away, and the young live in the sea for a month before returning to the coast, changing into air breathers, and slowly returning inland to begin the cycle once again. It can be inferred from the passage that _ . A) red crabs migrate by swimming in color1ful ocean waves B) the islanders are friendly to the migrating crabs C) red crabs live in the holes all the year round D) people have built special shelters for red crabs

A group of people from Denmark have formed the B-Society. According to them, human beings are divided into types: A-People, and B-People. A-People have no problem getting up in the morning, and operate much better earlier in the day. However, B-people are better later in the day. "I'm useless early in the morning," says one of the members of the B-Society."All I can do is drink coffee, and stare into space. People used to get up early because they had to feed the animals. But I haven't got any cows or chickens, so I can sleep late," She adds. Since the society was set up, the B-Society has welcomed several thousand members. Right now, the B-Society is fighting hard for businesses to join its B-certification list. Companies that are "B-certified" basically give their employees the opportunity to come in when they want. In some companies, employees arrive at any time up to 3:30 pm --- each to their own rhythm . And it is not just businesses that are benefiting from this. Teenagers who can't get out of bed in the morning, and parents who never quite get the kids to school on time, can now benefit from B-classes. From next year, a school in Copenhagen will offer classes which start later in the day (at 10 instead of eight). And even the government seems to like the idea. The B-Society was founded by Camilla Kring, a professor from the University of Copenhagen. On her website, she says, "When B-people's work rhythms are considered at the work place, their productivity and quality of life is increased, which can increase productivity for the entire organization." She adds that, "B-Society will create a new daily rhythm in schools and other institutions as an alternative to the current rhythm of 'early at work and early at home'. We are working for the establishment of kindergartens, primary and secondary schools as well as universities that open between 10 am and 8 pm." Would you like to work for a B-certified company? In B-certified companies, employees can _ . A) get more working opportunities B) join any other companies C) work on any days they choose D) go to work at any time of a day

Question: A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday. Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost. Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes. The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted from slower-speed, dial-up Internet access while the other half of families had no prior access. "The industry continues to chip away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates. "Entertainment applications will be the key. If anything will pull in the holdouts, it's going to be applications that make the Internet more similar to pay-TV," he predicted. According to John Barrett, what is the key to attracting more U.S. families to broadband service? A) making the Internet look more similar to TV set B) applying the Internet more to entertainment C) providing more pay-TV programs D) chipping away at the core of non-subscribers
