Part III Reading Comprehension (40 minutes)
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 a letter. Please mark the corresponding letter 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.

When travelling overseas, do you buy water in plastic bottles or 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 thing to do, right? The bottle is __27__ , and the label says "pure water". But maybe what's inside is not 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 analysed 259 bottles from 11 brands sold in nine countries, __31__ an average of 325 plastic particles per litre of water. These microplastics included a __32__ commonly known as PET and 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 organisation. About a million bottles are bought every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.

Confronted with this __34__ , several bottled-water manufacturers including Nestle and Coca-Cola undertook their own studies using the same methodology. These studies showed that their water did contain microplastics, but far less than the Orb study suggested. Regardless, the World Health Organisation has launched a review into the __35__ health risks of drinking water from plastic bottles.

A) adequate
B) admiring
C) contains
D) defending
E) evidence
F) instant
G) liquid
H) modified
I) natural
J) potential
K) released
L) revealing
M) sealed
N) solves
O) substance

Section B
Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one 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.

Make Stuff, Fail, And Learn While You're At It

A) We've always been a hands-on, do it-yourself kind of nation. Ben Franklin, one of America's founding fathers, didn't just invent the lightning rod. His creations include glasses, innovative stoves and more.

B) Franklin, who was largely self-taught, may have been a genius, but he wasn't really an exception when it comes to American making and creativity.

C) The personal computing revolution and philosophy of disruptive innovation of Silicon Valley grew, in part, out of the creations of the Homebrew Computer Club, which was founded in a garage in Menlo Park, California, in the mid-1970s. Members-including guys named Jobs and Wozniak-started making and inventing things they couldn't buy.

D) So it's no surprise that the Maker Movement today is thriving in communities and some schools across America. Making is available to ordinary people who aren't tied to big companies, big defense labs or research universities. The maker philosophy echoes old ideas advocated by John Dewey, Montessori, and even ancient Greek philosophers, as we pointed out recently.

E) These maker spaces are often outside of classrooms, and are serving an important educational function. The Maker Movement is rediscovering learning by doing, which is Dewey's phrase from 100 years ago. We are rediscovering Dewey and Montessori and a lot of the practices that they pioneered that have been forgotten or at least put aside. A maker space is a place which can be in a school, but it doesn't look like a classroom. It can be in a library. It can be out in the community. It has tools and materials. It's a place where you get to make things based on your interest and on what you, re learning to do.

F) Ideas about learning by doing have struggled to become mainstream educationally, despite being old concepts from Dewey and Montessori, Plato and Aristotle, and in the American context, Ralph Emerson, on the value of experience and self-reliance. It's not necessarily an efficient way to learn. We learn, in a sense, by trial and error. Learning from experience is something that takes time and patience. It's very individualized. If your goal is to have standardized approaches to learning, where everybody learns the same thing at the same time in the same way, then learning by doing doesn't really fit that mold anymore. It's not the world of textbooks. It's not the world of testing.

G) Learning by doing may not be efficient, but it is effective. Project-based learning has grown in popularity with teachers and administrators. However, project-based learning is not making. Although there is a connection, there is also a distinction. The difference lies in whether the project is in a sense defined and developed by the student or whether it's assigned by a teacher. We'll all get the kids to build a small boat. We are all going to learn about X, Y, and Z. That tends to be one form of project- based learning.

H) I really believe the core idea of making is to have an idea within your head—or you just borrow it from someone—and begin to develop it, repeat it and improve it. Then, realize that idea somehow. That thing that you make is valuable to you and you can share it with others. I'm interested in how these things are expressions of that person, their ideas, and their interactions with the world.

I) In some ways, a lot of forms of making in school trivialize （使变得无足轻重） making. The thing that you make has no value to you. Once you are done demonstrating whatever concept was in the; textbook, you throw away the pipe cleaners, the straws, the cardboard tubes.

J) Making should be student-directed and student-led, otherwise it's boring. It doesn't have the motivation of the student. I'm not saying that students should not learn concepts or not learn skills. They do. But to really harness their motivation is to build upon their interest. It's to let them be in control and to drive the car.

K) Teachers should aim to build a supportive, creative environment for students to do this work. A very social environment, where they are learning from each other. When they have a problem, it isn't the teacher necessarily coming in to solve it. They are responsible for working through that problem. It might be they have to talk to other students in the class to help get an answer.

L) The teacher's role is more of a coach or observer. Sometimes, to people, it sounds like this is a diminished role for teachers. I think it's a heightened role. You're creating this environment, like a maker space. You have 20 kids doing different things. You are watching them and really it's the human behaviors you're looking at. Are they engaged? Are they developing and repeating their project? Are they stumbling （受挫）？ Do they need something that they don't have? Can you help them be aware of where they are?

M) My belief is that the goal of making is not to get every kid to be hands-on, but it enables us to be good learners. It's not the knowledge that is valuable; it's the practice of learning new things and understanding how things work. These are processes that you are developing so that you are able, over time, to tackle more interesting problems, more challenging problems-problems that require many people instead of one person, and many skills instead of one.

N) If teachers keep it form-free and student-led, it can still be tied to a curriculum and an educational plan. I think a maker space is more like a library in that there are multiple subjects and multiple things that you can learn. What seems to be missing in school is how these subjects integrate, how they fit t together in any meaningful way. Rather than saying, "This is science, over here is history," I see schools taking this idea of projects and looking at: How do they support children in higher level learning?

O) I feel like this is a shift away from a subject matter-based curriculum to a more experiential curriculum or learning. It's still in its early stages, but I think it's shifting around not what kids learn but how they learn.

36.A maker space is where people make things according to their personal interests.
37.The teachers, role is enhanced in a maker space as they have to monitor and facilitate during the process.
38.Coming up with an idea of one's own or improving one from others is key to the concept of making.
39.Contrary to structured learning, learning by doing is highly individualized.
40.America is a nation known for the idea of making things by oneself.
41.Making will be boring unless students are able to take charge.
42.Making can be related to a project, but it is created and carried out by students themselves.
43.The author suggests incorporating the idea of a maker space into a school curriculum.
44.The maker concept is a modern version of some ancient philosophical ideas.
45.Making is not taken seriously in school when students are asked to make something meaningless to them based on textbooks.

Section C

Directions: In this section, you will hear a passage three times. When the passage is read for the first time，you should listen carefully for its general idea.When the passage is read for the second time，you are required to fill in the blanks with the exact words you have just heard. Finally，when the passage is read for the third time，you should check what you have written.

Passage One
Questions 46 to 50 are based 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 online Master of Science in Computer Science program. Professor Goel already had eight teaching assistants, but that wasn't enough to deal with the overwhelming number of daily questions from students.

Many students drop out of online courses because of the lack of teaching support. When students feel isolated 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 team 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 the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments 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 artificial intelligence, were interacting with the virtual assistant 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 year is to take over answering 40% of all the 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 artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.

46. What do we lear about Knowledge-Based Arificial Itelligence?
A) It is a robot that can answer students' questions.
B) It is a course designed for students to leamn online.
C) It is a high-tech device that revolutionizes teaching.
D) It is a computer program that aids student leaming.
47. What problem did Professor Goel meet with?
A) His students were unsatisfied with the assistants.
B) His course was too difficult for the students.
C) Students' questions were too many to handle.
D) Too many students dropped out of his course.
48. What do we lear about Jill Watson?
A) She turned out to be a great sucess.
B) She got along pretty well with students.
C) She was unwelcome to students at first.
D) She was released online as an experiment.
49. How did the students feel about Jill Watson?
A) They thought she was a bit too artificial.
B) They found her not as capable as expected.
C) They could not but admire her knowledge.
D) They could not tell her from a real person.
50. What does Professor Goel plan to do next with Jill Watson?
A) Launch different versions of her online.
B) Feed her with new questions and answers.
C) Assign her to answer more of students' questions.
D) Encourage students to interact with her more freely.

Passage Two
Questions 51 to 55 are based on the following passage.

Thinking small, being engaging, and having a sense of humor don't hurt. Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial.

Crowdfunding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to producing water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goals, but others have fallen short of reaching even modest targets.

To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Sch?fer of the University of Zurich examined the content of the webpages for 371 recent campaigns.

Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as Experiment.com and Petridish.org only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors, since projects that answered questions from interested donors fared better. And they target a small amount of money. The projects included in the study raised $4,000 on average, with 30% receiving less than $1,000. The more money a project sought, the lower the chance it reached its goal, the researchers found.

Other factors may also significantly influence a project's success, most notably, the size of a scientist's personal and professional networks, and how much a researcher promotes a project on their own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers' efforts to reach the public, and people give because "they feel a connection to the person" who is doing the fundraising—not necessarily to the science.

51. What do we learn about the scientists trying to raise money online for their projects?
A) They did not raise much due to modest targets.
B) They made use of mixed fundraising strategies.
C) Not all of them achieved their anticipated goals.
D) Most of them put movies online for the purpose.
52. What is the purpose of Mike Schafer' s research of recent crowdfunding campaigns?
A) To create atractive content for science websites.
B) To identify reasons for their different outcomes.
C) To help scientists to launch innovative projects.
D) To separate science projects from general ones.
53. What trait contributes to the success of a crowdfiunding campaign?
A) The potential benefit to future generations.
B) Its interaction with prospective donors.
C) Its originality in addressing financial issues.
D) The value of the proposed project.
54. What did the researchers think of the financial targets of crowdfunding projects?
A) They should be small to be sucessful.
B) They should be based on actual needs.
C) They should be assed with great care.
D) They should be ambitious to gain notice.
55. What motivates people to donate in a crowdfunding campaign?
A) The ease of access to the content of the webpage.
B) Their desire to contribute to the cause of science.
C) The significance and influence of the project itself.
D) Their feeling of connection to the scientists themselves.

2019年12月四级部分真题参考答案(完整版)

Part Ⅰ Writing

Hi Mark,

I'm so glad that you have made up your mind to teach English in China. Before you make a decision about your precise destination, let me introduce my hometown, Chongqing.

Located in southwest China, Chongqing may not enjoy worldwide fame as much as Beijing or Shanghai, but it is a thriving metropolis with lower cost of living. Working and living here, you can achieve your career goals without feeling too much stress. The locals are known for being warm and hospitable, and you can teach in a way that feels good for you. To be sure, teaching a foreign language in a city where residents speak a dialect all the time can be very challenging. It takes time indeed to correct pronunciation mistakes each student makes. But since you are always praised for your kindness and patience, it should hardly be an obstacle for you.

Anyway, I will support and help you as much as possible, whichever city you go to. I believe living and teaching in China will be a pleasant and memorable experience for you.

Best wishes,
Li Ming

Part IV Translation

Chinese families attach great importance to their children's education. Many parents hold that they should work hard to ensure their children's access to good education. Not only are they perfectly willing to invest in their children's education, but they also spend much time urging them to study. Most parents expect their children to get admitted to elite universities. Owing to China s reform and opening-up, an increasing number of parents can send their children to study abroad or participate in international exchange programs to broaden their horizons. Through these efforts, they expect their children grow up strong and healthy and make a contribution to the nation's development and prosperity.
