25、) Section A Directions:In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by

26、a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once. Questions 26 to 35 are based on the following passage. When travelling overseas, do you buy water in plastic bottles or

27、 take your chances with tap water? Imagine you are wandering about on a Thai island or 26 the ruins of Angkor. It’s hot so you grab a bottle of water from a local vendor. It’s the safe, sane thing to do, right? The bottle is 27 , and the label says “pure water”, but maybe what’s inside is not

28、 so 28 . Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 29 microplastics? That’s the conclusion of a recently 30 study, which analyzed 259 bottles from 11 brands sold in nine countries, 31 an average of 325 plastic particl

29、es per liter of water. These microplastics included a 32commonly known as PETand are widely used in the manufacture of clothing and food and 33 containers.The study was conducted at the State University of New York on behalf of Orb Media, a journalism organization.About a million bottles are bou

30、ght every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.

33、ne of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. The Quiet Heroism of Mail Delivery [A] On Wednesday, a

34、polar wind brought bitter cold to the Midwest. Overnight, Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colder than Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zero in Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Da

35、kota, according to the National Weather Service. Schools, restaurants, and businesses closed, and more than 1,000 flights have been canceled. [B] Even the United States Postal Service (USPS) suspended mail delivery temporarily. “Due to this arctic outbreak and concerns for the safety of USPS employ

36、ees,” USPS announced Wednesday morning, “the Postal Service is suspending delivery Jan. 30 in the following 3-digit ZIP Code locations.” Twelve regions were listed as unsafe on Wednesday; on Thursday, eight remained. [C] As global surface temperatures increase, so does the likelihood of extreme wea

37、ther. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and other natural disasters cost at least $49 billion in the United States. As my colleague Vann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017’s Hurrica

38、ne Maria. Natural disasters can wreck a community’s infrastructure, disrupting systems for months or years. Some services, however, remind us that life will eventually return, in some form, to normal. [D] Days after the deadly 2017 wildfires in Santa Rosa, California, a drone caught footage of a US

39、PS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to Rae Ann Haight, the program manager for the national-preparedness offic

40、e at USPS, Smith was fulfilling a request made by some of the home owners to pick up any mail that was left untouched. For Smith, this was just another day on the job. “I followed my route like I normally do,” Smith told a reporter. “As I’d come across a box that was up but with no house, I checked,

41、 and there was mail—outgoing mail—in it. And so we picked those up and carried on.” [E] USPS has sophisticated emergency plans for natural disasters. Across the country, 285 emergency-management teams are devoted to crisis control. These teams are trained annually using a framework known as the thr

42、ee Ps: people, property, product. After mail service stops due to weather, the agency’s top priority is ensuring that employees are safe. Thenit evaluates the health of infrastructure, such as the roads that mail carriers drive on. Finally, it decides when and how to re-open operations.If the destru

43、ction is extreme, mail addressed to the area will get sent elsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming New Orleans mail to existing mail facilities in Houston. Mail that was already processed in New Orleans facilities was moved to an upper floor so it would be prote

44、cted from water damage. [F] As soon as it’s safe enough to be outside, couriers start distributing accumulated mail on the still-accessible routes. USPS urges those without standing addresses to file change-of-address forms with their new location. After Hurricane Katrina hit in 2005, mail faciliti

45、es were set up in dozens of other locations across the country in the two weeks that USPS was unable to provide street delivery. [G] Every day, USPS processes, on average, 493.4 million pieces of mail—anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS

46、 told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of bills are paid online, which means that just under half of payments still rely on delivery services to be completed. [H] It can be hard to identify which pa

47、rcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They willcoordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence

48、 and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received on time. [I] Mail companies are logistics companies, which puts them in a special position to help when disaster strikes. In a 2011 USPS case study, the

49、agency emphasized its massive infrastructure as a “unique federal asset” to be called upon in a disaster or terrorist attack. “I think we’re unique as a federal agency,” USPS official Mike Swigart told me, “because we’re in literally every community in this country … We’re obligated to deliver to th

50、at point on a daily basis.” [J] Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster.For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affecte

51、d by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California, and donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transport

52、ation support for Hurricanes Florence and Michael.UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebuild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,” said Eduardo Martinez, the president of the

53、 UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriv

54、ing, prosperous,” he said. [K] Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a sense of normalcy can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities are still their

55、 communities.“When they see that carrier back out on the street,” Swigart said, “that’s the first sign to them that life is starting to return to normal.” 36. The United States Postal Service has a system to ensure its employees’ safety. 37. One official says USPS is unique in that it has more dir

56、ect reach to communities compared with other federal agencies 38. Natural disasters can have a long-lasting impact on community life. 39. Mail delivery service i$ still responsible for the completion of almost half of payments. 40. The sight of a mailman on the street is a reassuring sign of life

57、 becoming normal again. 41. After Hurricane Katrina interrupted routine delivery, temporary mail service points were set up. 42. Postal service in some regions in the U.S. was suspended due to extreme cold weather. 43. Private postal companies also support disaster relief efforts by distributing

58、urgent supplies. 44. A dedicated USPS employee was on the job carrying out duties in spite of extreme conditions. 45. Postal services work hard to identify items that require priority treatment. 【參考答案】 36-40 FIDGB 41-45EHAJC Section C Directions: There are 2 passages in this section. Each

59、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 Answer Sheet 2 with a single line through the centre. Passage One Questions 46 to 50 are based

60、 on the following passage. Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge Based Artificial Intelligence. This online course is a core requirement of Georgia Tech’s o

61、nline Master of Science in Computer Science program. Professor Goel already had 8 teaching assistants, but that wasn’t enough to deal with the overwhelming number of questions from students. Many students drop out of online courses because of the lack of teaching support. When students feel isolate

62、d or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform. Goel and his t

63、eam developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to

64、feed Jill the questions and answers. After some adjustment and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artifici

65、al intelligence, were interacting with artificial intelligence and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience. The goal of Professor Goel’s virtual assistant next ye

66、ar is to take over answering 40% of all questions posed by students on the online forum. The name, Jill Watson, will of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak. 46. What do we learn about Knowledge-Based Artificial Intelligence? A) It is a robot that can answer students’ questions. B) It is a course designed for students to learn online. C) It is a high-tech
