Reading Comprehension (2’X20=40’) Directions: Read the following three passages carefully and do the multiple-choice questions. Passage One Dogs are social animals and without proper training, they will behave like wild animals. They spoil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong things. The key to preventing or treating behavior problem is learning to teach the dog to redirect its normal behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit”, it is showing obedience and respect for you. It is necessary to establish yourself as top dog or leader of the dog pack by using extreme measures. You can teach your dog its subordinate role by teaching it to show submission to you. Most dogs love performing tricks for you pleasantly if they accept that you are in charge. Tainting should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and more safely allowed a greater amount of freedom than an untrained animal. 1. Behavior problems of dogs are believed to _______. A) worsen in modern society B) be just part of their nature C) occur when they go wild D) present at threat to the community 2. The primary purpose of obedience training is to ________. A) enable the dog to regain its normal behavior B) teach the dog to perform clever tricks C) make the dog aware of its owner’s authority D) provide the dog with outlets for its wild behavior 3. Effective communication between a dog and its owner is _______. A) an extreme measure in obedience training B) a good way to teach the dog new tricks C) the foundation for dogs to perform tasks D) essential to solve the dog’s behavior problems 4. Why do pet dogs love performing tricks for their masters? A) To show their willingness to obey. B) To show their affection for their masters. C) To avoid being punished. D) To win leadership of the dog pack. 5. When a dog has received effective obedience training, its owner________. A) will enjoy a better family life. B) can give the dog more freedom C) can give the dog more rewards D) will have more confidence in himself Passage Two: Once upon a time there was a wise man that used to go to the ocean to do his writing. He had a habit of walking on the beach before he began his work. One day he was walking along the shore. As he looked down the beach, he saw a human figure moving like a dancer. He smiled to himself at the thought of someone who would dance on the beach. So he began to walk faster to catch up.

2018年大学英语第一学期期末考试(A卷) Part II Reading Comprehension (30 %) Directions: There are four passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage One Science is not a set of unquestionable results but a way of understanding the world around us. Its real work is slow. The scientific method , as many of us learned in school, is a gradual process that begins with a purpose or problem or question to be answered. It includes a list of materials, a procedure to follow, a set of observations to make and, finally, conclusions to reach. In medicine, when a new drug is proposed that might cure or control a disease, it is first tested on a large random group of people, and their reactions are then compared with those of another random group not given the drug. All reactions in both groups are carefully recorded and compared, and the drug is evaluated. All of this takes time and patience. It’s the result of course, that makes the best news—not the years of quiet work that characterize the bulk of scientific inquiry. After an experiment is concluded or an observation is made, the result continues to be examined critically. When it is submitted for publication, it goes to a group of the scientist’s colleagues, who review the work. Einstein was right when he said: “No amount of experimentation can ever prove me right, a single experiment can at any time prove me wrong.” In August 1996, NASA announced the discovery in Antarctica of a meteorite（流星）from Mars that might contain evidence of ancient life on another world. As President Clinton said that day, the possibility that life existed on Mars billions of years ago was potentially one of the great discoveries of our time. After the excitement wore down and initial papers were published, other researchers began looking at samples from the same meteorite. Some concluded that the “evidence of life”was mostly contamination from Antarctic ice or that there was nothing organic at all in the rock. Was this a failure of science, as some news reports trumpeted? No! It was a good example of the scientific method working the way it is supposed to. Scientists spend years on research, announce their findings, and these findings are examined by other scientists. That’s how we learn. Like climbing a mountain, we struggle up three feet and fall back two. It’s a process filled with disappointments and reverses, but somehow we keep moving ahead.
