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 ADirections: 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 drugssuch 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 ofcooling,” 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 increase in the force that could be applied to the paw. The team say the implant’s benefits include (30)_______, in contrast to opioids, it is not addictive. As the implant is made with water-soluble and biocompatible materials, it can break down in the body after use. The implant could be inserted as an extension of the patient’s initial surgery.Section BDirections: Complete the following passage by using the -words in the box. Each word can only be used once. Note that there is one more word than you need.A. attachedB. bottle-fedC. confusionD. invisibleE. originallyF. orphanedG. partneringH. procedureI. reproducedJ. subjectsK. unintentionallySaving Baby BearsReacting to the auditory assault of barking dogs, shouts and rifle blasts, a 168-pound American black bear shot out and hightailed (迅速逃走)it into the woods off a logging road.His sister, weighing in at 135 pounds, took a little more time to overcome her fear and (31) _______ before she, too, ran for the trees and away from the humans who had driven more than 100 miles to witness the bears’ return to the wild.The cubs were the 106th and 107th (32) _______ or injured bears to be raised or treated at the Progressive Animal Welfare Society (PAWS) Wildlife Center in Washington state, then released months later in the same general area where they were (33) _______found. Fitted with GPS collars and tattooed with identification numbers on their gums, the bears are also among the latest (34) _______of a long-term research study being conducted by Rich Beausoleil and Lindsay Welfelt, both biologists and bear and cougar specialists.The siblings were only two weeks old when a forest worker and his dog (35) _______ disturbed their den in February 2020, scaring away their mother. She never returned.The worker contacted the WDFW, an agency (36) _______with PAWS to rehabilitate sick, injured wild animals before releasing them back into their natural habitats."Their eyes and ears weren't open, and their teeth hadn't evenerupted,Jennifer Convy, PAWS senior director of wildlife, said of the cubs, which each weighed less than 2 pounds when they arrived and were the youngest ever to be raised at the center.Though (37) _______at first, the cubs weren't cuddled. Instead, their caregivers wore bear- scented bear suits during feedings once the cubs' eyes had opened. At PAWS, the staff and volunteers take pains to be (38)_______to all the animals in their care."They don't see us, ever. We don't talk to them. We don't name the animals because we don't want our staff or volunteers to get (39)_______，“ Convy said. After more than a year, the bear siblings were released.The wildlife biologists are studying how the bears raised at PAWS fare after their release, compared to their wild-reared brethren. One cub released in 2017 had her first litter of cubs in January."We've been to her den several times." Beausoleil said. "She (40)_______ and had cubs of her own ... This was kind of a turning point for us."After all, the whole point of PAWS' rehabilitation "is to protect and perpetuate (使持续) the species," he said.III. Reading Comprehension (45 分)Section A (每题1分，共15分)Directions: For each blank in the following passage there are four wordsor phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.The Other da Vinci CodeFor centuries, two of the most intriguing questions about Leonardo da Vinci's "Mon a Lisa" were "Who " and "When ”A(n) (41) _______made at Heidelberg University in 2005 pretty much answered both. A note written in a manuscript in the library (42) _______the account of da Vinci's first biographer, Giorgio Vasari: that the sitter was a merchanfs wife, Lisa Gherardini. The note also helped date the masterpiece to between 1503 and 1506.A(n) (43)_______ mystery-"Where "- is still in dispute. But on June 3rd a French engineer, Pascal Cotte, declared that he and a collaborator had (44) _______the landscape in the background of the painting. Arguments had (45)_______ been made for stretches of countryside in the Marche region and between Milan and Genoa. During a presentation in Vinci, near Florence, Mr Cotte maintained that the artist was more plausibly depicting a part of his native Tuscany 一one that keenly interested him at the time. According to this theory, da Vinci represented the area not as it was, but as, in an unrealised scheme, he (46) _______ it to be.Mr Cotte, who was asked by the Louvre (where the "Mona Lisa" hangs) to create a digital image of the painting, is the inventor of themultispectral camera: a device that can detect not only the drawing below the (47) _______of an oil painting, but also, where they exist, intermediate layers of work. It was among these, under what appears to be a pointed rock, that he found a(n) (48) _______sketch showing that da Vinci meant it to represent a castellated tower.The landscape of the "Mona Lisa" also includes a huge overhanging cliff. That is (49)_______ to one that da Vinci included in a sketch of a fortress (堡垒)contested by Pisa and Florence in the war that flared between them in 1503 (around the time he was painting Gherardini). The (50)_______ with the nearby cliff ——and a tower, known as the Caprona tower 一all overlook the river Amo as it snakes from Florence to Pisa. All three also feature in drawings made by da Vinci to illustrate a plan about which, says Mr Cotte, he became “(51) _______”.This involved diverting the Amo to (52) _______Pisa's water supply and give Florence an outlet to the Mediterranean. In the early 1500s, with the two citystates at war, the idea was under active consideration. Mr Cotte argues that a(n) (53) _______ winding through desolate countryside at the right of the "Mona Lisa" is too wide to be a road, as some have speculated, and is(54) _______the driedup bed of the Amo as da Vinci envisaged (设想)it once his plan had been adopted.It never was. But if Mr Cotte's theory is right, it might just explain why Gherardini, a Florentine, exhibits such a contented, if mysterious, (55)_______。

He called that unit one horsepower. With this unit he couldmeasure the work his steam engine could do.He discovered that a horse could lift a 3300-pound weight 10 feet intothe air in one minute. His engine could lift a 3300-pound weight 100 feetin one minute.Because his engine did ten times as much work as the horse, Watt calledit a ten horsepower engine.BABAC11.

They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice.At last they pulled the box into the basket. It was still snowing; so they climbed to get away from the snow. They rose to 5,100 metres! Everything became icy. They were so cold that they decided to land. They came down in Poland heavily but safely. They had travelled 1,797 kilometers from London! BABAC6.

The cigarette industry started in the 1870’s with the development of the cigarette manufacturing machines. It helped produce great numbers of cigarettes very quickly and reduced the price greatly. And consequently more and more people, both men and women, began to smoke cigarettes. Men as a group, however, smoke more than women. But the highest proportion of smokers is found in the age group of 24 - 44, regardless of sex difference.Income, education, and occupation all play a part in determining a p erson’s smoking habits. City people smoke more than people living on farms. Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. 0n the other hand, if a well-educated man with a higher income smokes at all, he is likely to smoke more packs of cigarettes per day.The situation is somewhat different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower education groups. These more highly educated women tend to smoke more heavily.Among teenagers the picture is similar. There are fewer teenaged smokers from upper-income, well-educated families, and fewer from families living in farm areas- High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both their parents smokeCBDBC21. When did cigarettes smoking begin to become a widespread habit among menand women according to the author?A. Before 1870’s.B. In the year of 1870.C. When cigarettes were made in large numbers.D. When women began to smoke cigarettes. 22.

Students under twenty.23. Which of the following has little to do with a person’s smoking habit?A. How much money he earns.B. What kind of job he does.C. How much education he has got.D. How long he has worked.24. Which is TRUE according to the passage?A. Well-paid men with good education are more likely to smoke.B. Women with high family income and good education are more likely tosmoke.C. Generally speaking, well-educated women with higher income smoke veryfew cigarettes.D. well-educated men usually smoke more packs of cigarettes thanwell-educated women.25.
