高考英语上海卷 模拟试卷（二） 考生注意： 1.考试时间120分钟，试卷满分140分。 2.本考试设试卷和答题纸两部分。 第I卷（共90分） I. Listening Comprehension （25 分） Section A （每题1分，共10分） Directions: In Section A, you will hear ten short conversations between two speakers. At the end of each conversation, a question will be asked about what was said. The conversations and the questions will be spoken only once. After you hear a conversation and the question about it, read the four possible answers on your paper, and decide which one is the best answer to the question you have heard. II. Grammar and Vocabulary (每题 1 分,共 20 分) Section A Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, used one word that best fits each blank. An implant that can cool nerves to block pain signals has been unveiled by researchers who say the device could offer an alternative to drugs such as opioids (类鸦片活性肽). The team behind the device say it could bring benefits for management of acute pain such as (21)_____ experienced after amputations (截肢)or nerve grafts. "We are optimistic that this represents a very promising starting point for an engineering approach (22)_____ treating pain,” said Prof John Rogers of Northwestern University in the US, a co-author of the research. But he cautioned that it might be some time (23) _____ they were available to patients. "As with any implantable device, the regulatory process can be slow, typically (24) _____ (involve) much more extensive animal model studies over a period of years," he said. Writing in the journal Science, the team report that the device to block pain signals, which (25) _____(test) only on rats so far, involves a pump, external control system and an implant made from a soft, rubbery substance. The latter forms a sealed collection of tiny channels which form a twisting path in the part of the implant that sits around the target nerve like a cuff. When liquid coolant and dry nitrogen flow through the implant, the liquid causes a drop in temperature. An electronic sensor in the device allows the temperature at the nerve (26) _____(keep) constant. "All body processes are based on metabolic chemical reactions, motions of ions and flows of fluids--all (27) _____slow down as a result of cooling,” said Rogers. “ The net effect when cooling is applied to a nerve is in blocking of electrical signals." Among their experiments, the team tracked two rats with an injury, recording over a three- week period the minimum force that (28) _____be applied to the hind paw to cause the animal to retract (缩回)it. This data was then compared against three rats who were similarly injured but also had the implant. The results suggest bouts of cooling of the injured nerve from 37℃ to 10℃led to (29) _____(severe) pain, with a sevenfold in ... ...
