The future of pinnipeds looks much brighter today than it once did. At one time, about 100 years ago, it seemed certain that many pinnipeds in the world would be destroyed by human hunters. Today, it appears that most species( ) of pinnipeds are out of danger. Hunting was not controlled during the 18th and 19th centuries, because little was known about the lives of pinnipeds. Whales and pinnipeds were hunted for the oil from their body fat. This oil was used in lamps before electric lights were invented. Millions of seals and other pinnipeds were used to provide oil for the lamps of the world. As a result, the numbers of many pinniped species fell rapidly. Several things happened that helped to save pinnipeds. First, species that were hunted to near extinction were left alone because their numbers were too low and the cost of hunting them went up greatly. At the same time, electric lights were invented and the market for seal oil became smaller. Finally, governments around the world made laws to protect pinnipeds. As a result of all these things, the numbers of most pinniped species have grown in recent years. With some species, such as Northern fur seals, there may be as many animals alive today as there were before all the hunting began. However, oil is still a danger to pinnipeds and all sea animals. But this time it's not because they are hunted for their oil. The oil that puts them in danger is from oil spills in the sea. The oil covers their fur and reduces their body temperatures. Oil also sticks to the foods they eat. This modern danger to pinnipeds and their environment is one we must work to prevent. In which part of a magazine can we most probably read this passage? A) Wildlife. B) Lifestyle. C) Tourism. D) Environment.

(Question)
Digital technology -- email and smart phones especially -- have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it and only 35 percent say it's tolerated. Skeptical bosses will likely have their doubts reinforced by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while "working" remotely, while 35 percent have done housework,and 28 percent have cooked dinner. It is true, however,that working at home makes people much more efficient , because it allows workers to take care of annoying housework while still getting their jobs done. It's much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush. The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker. More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who have worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough flexibility to manage their time efficiently. Why do some employers hesitate to allow remote working? A) They fear losing control of their workers. B) They want to stick to their routine practice. C) They have little trust in modem technology. D) They are used to face-to-face communication.

Ques: Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it's a chance in million. People have made a census ( ) to colors of more than four thousand kinds of flowers and discovered that only eight of them are black. As we know, sunlight is formed by seven different colored lights. The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat. The passage tells us that _ . A) black flowers are so weak that it is difficult for them to grow up. B) there is only eight black flowers in nature. C) sunlight is formed by seven different colored lights, so the wave length of each light is different. D) black flowers can take in the light of all the wave lengths which make them dry up because of high temperature.
