There's been a lot of talk about white-and-blue collar workers, and you may have even heard of gold collar workers, but lately a new color of collar is making its way into China's urban vernacular --green. Green collars say no when work is life and life is work. They choose to get out of the fast lane , and explore new ways of living "green". Living green doesn't mean someone is working as an environmentalist, biologist or scientist. Instead it is more of a lifestyle choice. A typical green collar is well educated like a white-collar but physically tough like a blue-collar, likely born in the 70s or 80s of the last century and living in one of China's big cities, with a monthly income well above 5,000 yuan (about US $700). The life of a green collar may go something like this; Turn off the mobile phone after work, eat only healthy food rich in vitamins, go on hikes every weekend, and like to help _ Green collars even have their own club. In Beijing, the Green Collar Club is for people who share a "be happy, healthy and helpful" spirit. The club often holds charity parties and uses the donations for environmental protection and poverty relief projects in China. "They are successful in their careers, but do not miss the pleasures in life. They have a lot of money, but do not fall slave to it." said Zuo Shiguang, one of the founding members of the club. What is the passage mainly about? A) Differences between white-and-blue collars and green collars. B) The increasing awareness of environmental protection. C) New trends of life in China's big cities. D) The lifestyle of green collars.

Many birds migrate. This means that every year they fly somewhere warm in the winter and then return to the place they came from in the spring. One mystery is how birds know how to travel such long distances without getting lost. Scientists have wondered for years whether they are born with the knowledge of where to go or whether they learn it after they are born. Now, researchers have found evidence that shows that one type of bird, at least, learns how to migrate. The bird is the whooping crane , a tall, white bird that lives in the United States. In the 1940s, the number of these birds decreased to fewer than 25 individuals, and many people feared that they would die out. Thanks to efforts to save them, they have now increased to about 600. However, the birds are not very good at taking care of their young. Because of this, eggs are brought to a site in Maryland. There, scientists from the Whooping Crane Eastern Partnership raise the baby birds. Later, the young birds are taken from Maryland to Wisconsin, where the scientists teach them how to fly. From there, they fly about 2,200 kilometers south to Florida to spend the winter. The first time, scientists lead the way in a small airplane. From the second year, though, the birds travel by themselves. For 14 years, the scientists have kept a careful record of every flight the birds have taken between Wisconsin and Florida. They have also recorded which birds fly together, the relationships between the birds, and the gender of each bird. When scientists analyzed the data, they were surprised by the results. These showed that each bird took a very different route. However, as they got older, they flew more and more directly between Wisconsin and Florida. This continued until they were five years old. This indicates that the birds gradually learned the best route to take. Moreover, when an older bird was in a group, the whole group flew more directly. This suggests that the older birds taught the younger ones a quicker route. Scientists say that this evidence... What do we learn from the data? A) Most birds like to visit new places when migrating. B) Most birds stop flying to Florida when they are five years old. C) Younger birds prefer not to fly together with older birds. D) Younger birds are able to gain an important skill from older ones.

Question: We all know that eating junk food can make us fat. However, a new study suggests that it can do more than that - it can also make us lazy, reported CBS News. In the study, researchers at the University of California, Los Angeles, US divided 32 female rats into two groups. The first group was fed a diet of healthy food such as corn and fish, while the second was given a diet of highly processed food rich in sugar, namely "junk food". Within three months, the rats in the second group were already much fatter than those on the healthy diet. And when researchers trained the rats to do simple tasks, they found even more differences between the two groups rather than weight. During the task - pushing a lever to receive a reward of sugar water - the rats on the junk food diet were found to be less willing to move, and they took longer breaks between each push than the lean rats did. "It is as if the rat is thinking 'This is too much work'," Aaron Blaisdell, leader of the study, told the Los Angeles Times. But what about the possibility that the fat rats were less passionate about getting sugar water because they were already eating lots of sugar in their daily diet? That's why researchers repeated the tests by rewarding fat rats with plain water when they were extremely thirsty. However, the results came out just the same. According to researchers, these differences suggest that junk food changed the chemistry in the rats' brains. The experiment didn't end _ . After six months, the rats' diets were switched, and the overweight rats were given a healthy diet for nine days. However, this change didn't help reduce their weight or improve their ability to perform tasks, which means the effects of their junk food diet persisted . "There's no quick fix," said Blaisdell. For a long time, we've believed that people become fat because they are lazy. But this study has proven the opposite to be true as well, which indicates that laziness and obesity are a "vicious cycle ". So, if you constantly feel tired, lacking any... Which of the following is Not Right according to the passage? A) Eating junk food can make us fat. B) Researchers got different results after repeated the tests to fat rats. C) For a long time, we've believed that people become fat because they are lazy. D) If you constantly feel tired or study too hard, you need to pay attention to your diet.
