单选题How man first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that man, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to stand for those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of word, then lies in their association with the things they bring up before our minds. Words became filled with meanings for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase. Great writers are those who not only have great thoughts but also express these thoughts in words that appeal powerfully to our minds and emotions. We should therefore learn to choose our words carefully and use them exactly, or they will make our speech silly and impolite.

单选题In response to his summons, I had entered the room and shut the door quietly behind me. There was a pause of complete stillness of painful hesitation. His voice was harsh (刺耳的)when he spoke, and the words uncompromising, but I had seen him wet his lips and make the attempt twice, "Well, Annabel?" I went quickly across the room and knelt down beside the sofa and put my hands on his lap on top of the plaid rug. His thin hand, with its prominent(突出的)blue-knotted veins(血管), came down hard over mine, surprising strong and warm. In the end it was easy to know what to say. I said quite simply, "I am sorry, Grandfather. Will you have me back?" The hand moved, holding mine together even more tightly. "If I said no," said Grandfather, "it would be no more than you deserve." He cleared his throat violently. "We thought you were dead." "I am sorry." His other hand reached forward and lifted my chin. He studied my face, turning it towards the light of the window. I bit my lip and waited, not meeting his gaze. He said nothing for a long time, then, as harshly as before. "You have been unhappy, haven"t you?" I nodded. He let me go, and at last I was able to put my forehead down on the rug so that he couldn"t see my face. He said "So have we," and fell silent patting my head.

单选题"It"s not what you know, but who you know that counts." This over-simplified statement often angers those who believe that all it takes to get ahead is hard work. However, you can"t ignore that there is some truth in the statement when it comes to looking for a job. In fact, the U.S. Department of Labor estimates that 48 percent of all job connections are made through personal networking. So the real question for job seekers is how to take advantage of this phenomenon. Positioning (使……处于适当位置) yourself to take advantage of the benefits of networking is not that difficult. It only requires participation in social and business events particularly those that relate to your professional objectives. It"s a three-step process: first, choosing a promising event to attend; second, once there, making sure you get your message out; and third, sending a resume after a positive conversation. The ready-made social situations created by professional associations are obvious places to network. Almost every professional associations portrays itself as a networking vehicle for matching jobs with prospective candidates. If you don"t belong to a professional group, the act of joining one will get you in the door. Once inside you have the opportunity to meet many influential people. Beyond the social and business gatherings, networking has recently taken a turn toward our electronic future. The internet is becoming a networking medium for communication about job opportunities and job seekers.

单选题The dog has always been considered man"s best friend. Always noted for being particular faithful in watching over children, he also has his place by the fireside, in the cow pasture, on the sheep range, and beside the hunter or blind. He is easy to train, works hard, and often performs astonishing feats. And in the frozen polar regions, he was once the principal motive power, before being largely replaced by the plane and helicopter . Because he howls or whines in the presence of impending death, the dog was once thought to have supernatural powers and believed to be capable of seeing gods and ghosts invisible to people. Actually, the basis for these beliefs lies in the dog"s sensitivity to people"s feelings and his superior hearing ability and sense of smell, which enable him to detect signs hidden from human observation. His record of saving lives is outstanding, for he often gives warning of fire and other dangers not noticed by his master. The dog"s major contribution, however, has been to medical research. Both his diet and his structure are comparable to those of the human being, and so he has been the subject, of countless demonstrations and experiments. Open-heart surgery has been made possible largely because of the dog. But his sacrifice has repaid his own species as well by safeguarding it from rabies(狂犬病), distemper, and other diseases.
