Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various species in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight. Trained and tamed for many generations, domestic animals are not accustomed to roaming in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require. All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps , and then wonder why the animal seems tired and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health. Even well cared for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health. When an animal doesn't get enough food, it will probably _ . A) refuse to obey its master B) immediately fall ill C) require its master to offer some food D) seek for food on its own

TOKYO-- At first glance, Japanese cellphones are young people's favorites, with elegant design and quick access to the Internet. However, despite years of competition in overseas markets, Japan's cellphone makers have little presence beyond the country's shores. The only Japanese cellphone maker with any meaningful global share is Sony Ericsson, and that company is a London-based joint venture between a Japanese electronics maker and a Swedish telecommunications firm. And Sony Ericsson has been hit by big losses. Its market share was just 6.3 percent in the first quarter of 2009, behind Nokia of Finland, Samsung Electronics and LG of South Korea, and Motorola of Illinois. This year, Mr Natsuno, who developed a popular wireless Internet service called i-Mode, invited some of the best minds in the field to debate how Japanese cellphones could go global. "The most amazing thing about Japan is that even the average person out there will have a very advanced phone, "said Mr Natsuno. Japan has 100 million users of advanced third-generation smart phones, twice the number of the United States, a much larger market. Many Japanese rely on their phones, not a PC, for Internet access. Indeed, Japanese cellphone makers thought they had positioned themselves to dominate the age of digital data. But they were a little too clever. In the 1990s, they set a standard for the second-generation network that was refused everywhere else. Then Japan quickly adopted a third-generation standard in 2001. However, it made Japanese phones too advanced for most markets. Several Japanese companies are now considering a push into overseas markets, including NEC. Panasonic, Sharp, Toshiba and Fujitsu are said to be planning similar moves. "Japanese cellphone makers need to either look overseas, or exit the business", said Kenshi Tazaki, a managing vice president at the consulting firm Gartner Japan. Why are Japanese cellphone makers a little too clever? A) Because their technical standards are too advanced to be accepted overseas. B) Because they only produce advanced cellphones. C) Because they used the second-generation network earlier than others. D) Because their phones are more advanced than PCs.

Q: It is thought that crying is hardly an activity encouraged by society. Tear, whether they are of sorrow, anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears is likely to apologize, even when a great tragedy was the cause. The observer of tears is likely to do everything possible to put an end to the emotional tears. But judging from recent studies of crying behavior, _ to tears are often inappropriate and may even be counterproductive . Humans are the only animals clearly known to shed emotional tears. Since evolution has given rise to few purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance (increase) survival. Although some observers have suggested that crying is a way to ask for assistance form others (as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vocal cries would have been quite enough, more likely than tears to gain attention. So, it appears, there must be something special about tears themselves. Indeed, the new studies suggest that emotional tears may play a direct role in alleviating stress, University of Minnesota researchers who are studying the chemical composition of tears have recently isolated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance. Other researchers are investigating the usefulness of tears as a means of diagnosing human ills and monitoring drugs. At Tulane University's Teat Analysis Laboratory Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse, to study the causes of "dry eye" syndrome and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants. What does the passage mainly talk about? A) Roles of emotional tears. B) functions of shedding tears. C) Unwelcome shedders of tears. D) Research on the effects of tears.

I was on my way home by train. The train's gentle rocking made me feel sleepy, despite the fact that I was standing with what felt like a building in the bag on my back. I turned slightly to reduce some of the pain in my shoulder and saw the door at the end of the car. An obviously homeless man walked through the door. He was dressed in a dirty heavy coat. He dragged a bag that looked thirty times as heavy as mine. He asked people for spare change in the polite, experienced voice of a person who had done this before. I glanced down as I did a quick check of my pockets, hoping for spare change to give him that wouldn't leave me short for the rest of the week. I came up empty and lifted my head just as his path crossed mine. Shrugging apologetically, I told him I had no change, expecting him to move through the door next to me and continue going to the next cars. However, he stood and stared at me, saying something quietly. Then I realized he was asking me to take him home. Suddenly money didn't matter that much to this man who lived in poverty without even enough money to purchase socks to stave off the chill. Not food, not clothes, not even a blanket. Just affection. I felt worse than I had done about not finding any spare change. My heart sank and I couldn't even think of the proper words to say besides "I can't, I'm sorry." He asked me, "What's wrong with my request?" The answer was on my lips before I knew it. I told him that I was not good enough for him. It was after the man had left that I thought about the answer I had given him and wondered why it felt so right to say so. I realized that I should have requested love over money or food. The fact that he could appreciate something so simple and invisible is more than I could ever have expected of myself. When the author was sleepy and tired, he saw a homeless man on the train _ . A) looking for his long-lost friend B) asking people for spare clothes C) begging passengers for some money D) talking about his painful experience
