查看答案和解析>> 科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解 How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs. What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body. Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed. A CAT scanner, however, uses a group of X rays to give a cross-sectional(橫截面)view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient. Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays. CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives. 小題1:What is NOT true of a CAT scan?
查看答案和解析>> 科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解 Some years ago, on a hot summer day in south Florida, a little boy decided to go for a swim in the old swimming hole behind his house. He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator (美洲鱷) was swimming toward the shore. His father working in the yard saw the two as they got closer and closer together. In utter fear, he ran toward the water, yelling to his son as loudly as he could. Hearing his voice, the little boy became alarmed and made a U – turn to swim to his father. It was too late. Just as he reached his father, the alligator reached him. From the dock, the father grabbed his little boy by the arms just as the alligator snatched his legs. That began an incredible tug – of – war (拔河) between the two. The alligator was much stronger than the father, but the father was much too passionate to let go. A farmer happened to drive by, took aim and shot the alligator. Remarkably, the little boy survived. His legs were extremely scarred by the vicious attack of the animal. And, on his arms, were deep scratches where his father’s fingernails dug into his fresh in his effort to hang on to the son he loved. The newspaper reporter who interviewed the boy asked if he would show his scars. The boy lifted his pant legs. And then, he said to the reporter, “But look at my arms. I have great scars on my arms, too. I have them because my dad wouldn’t let go.” You and I can identify with that boy. We have scars, too. No, not from an alligator, but the scars of a painful past. Some of those scars are unsightly and have caused us deep regret. But, some wounds, my friend, are because someone has refused to let go. In the midst of your struggle, someone has been there holding on to you. If you have the scars of someone’s love on your arms, be very, very grateful. Someone in your life did not and will not ever let you go. Never judge another person’s scars, because you don’t know how they got them. 小題1: Which of the following is the most closely related to the underlined word “passionate”?
