In the past 12 months, Nigeria has suffered from a shrinking economy, a sliding currency, and a prolonged fuel shortage. Now, Africa’s largest economy is facing a food crisis as major tomato fields have been destroyed by an insect, leading to a nationwide shortage and escalating prices.
The insect, Tutaabsoluta, has destroyed 80% of farms in Kaduna, Nigeria’s largest tomato-producing state, leading the government there to declare a state of __26__.The insect, also known as the tomato leaf miner, devastates crops by __27__ on fruits and digging into and moving through stalks. It 28 incredibly quickly, breeding up to 12 generations per year if conditions are favorable. It is believed to have 29 in South America in the early 1900s, and later spread to Europe before crossing over to sub-Saharan America.
In Nigeria, where tomatoes are a staple of local diets, the insect’s effects are devastating. Retail prices for a 30 of tomatoes at local markets have risen from $0.50 to $2.50. Farmers are reporting steep losses and a new $20 million tomato-paste factory has 31 production due to the shortages.
Given the moth’s ability also to attack crops like pepper and potatoes, Audu Ogbeh, Nigeria’s minister of agriculture, has warned that the pest may “create serious problems for food 32 “in the country. Ogbeh says experts are investigating how to control the pest’s damage and prevent its spread, which has gone largely 33 until now.
Despite being the continent’s second-largest producer of tomatoes, Nigeria is 34 on $1 billion worth of tomato-paste imports every year, as around 75% of the local harvest goes to waste thanks to a lack of proper storage facilities. A further 35 in local supplies is yet another unwelcome setback to the industry.

Direction: 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.
[A] It is a movement building steady momentum: a call to make research data, software code and experimental methods publicly available and transparent. A spirit of openness is gaining acceptance in the science community, and is the only way, say advocates, to address a “crisis” in science whereby too few findings are successfully reproduced. Furthermore, they say, it is the best way for researchers to gather the range of observations that are necessary to speed up discoveries or to identify large-scale trends.
[B] The open-date shift poses a confusing problem for junior researchers. On the one hand, the drive to share is gathering official steam. Since 2013, global scientific bodies have begun to back policies that support increased public access to research. On the other hand, scientists disagree about how much and when they should share data, and they debate whether sharing it is more likely to accelerate science and make it more robust, or to introduce vulnerabilities and problems. As more journals and funders adopt data-sharing requirements, and as a growing number of enthusiasts call for more openness, junior researchers must find their place between adopters and those who continue to hold out, even as they strive to launch their own careers.
[C] One key challenge facing young scientists is how to be open without becoming scientifically vulnerable. They must determine the risk of jeopardizing a job offer or a collaboration proposal from those who are wary of—or unfamiliar with – open science. And they must learn how to capitalize on the movement’s benefits, such as opportunities for more citations and a way to build a reputation without the need for conventional metrics, such as publication in high-impact journals.
[D] Some fields have embraced open data more than others. Researchers in psychology, a field rocked by findings of irreproducibility in the past few years, have been especially vocal supporter of the drive for more-open science. A few psychology journals have created incentives to increase interest in reproducible – for example, by affixing an “open-data” badge to articles that clearly state where data are available. According to social psychologist Brian Nosek, executive director of the Center for Open Science, the average data-sharing rate for the journal Psychological Science, which uses the badges, increased tenfold to 38% from 2013 to 2015.
[E] Funders, too, are increasingly adopting as open-data policy. Several strongly encourage, and some require, a data-management plan that makes data available. The US National Science Foundation is among these. Some philanthropic (慈善的) funders, including the Bill & Melinda Gates Foundation in Seattle, Washington, and the Wellcome Trust in London, also mandate open data from their grant recipients.
[F] But many young researchers, especially those who have not been mentored in open science, are uncertain about whether to share or to stay private. Graduate students and postdocs, who often are working on their lab head’s grant, may have no choice if their supervisor or another senior colleague opposes sharing.
[G] Some fear that the potential impact of sharing is too high, especially at the early stages of a career. “Everybody has a scary story about someone getting scooped （被抢先）,” says New York University astronomer David Hogg. Those fears may be a factor in a lingering hesitation to share data even when publishing in journals that mandate it.
[H] Researchers at small labs or at institutions focused on teaching arguably have the most to lose when sharing hard-won data. ”With my institution and teaching load, I don’t have postdocs and grad students,” says Terry McGlynn, a tropical biologist at California State University, Dominguez Hills, ”The stakes are higher for me to share data because it‘s a bigger fraction of what’s happening in my lab.”
[I] Researchers also point to the time sink that is involved in preparing data for others to view. Once the data and associated materials appear in a repository （储存库）, answering questions and handing complaints can take many hours.
[J] The time investment can present other problems. In some cases, says data scientist Karthik Ram, it may be difficult for junior researchers to embrace openness when senior colleagues—many of whom head selection and promotion committees—might ridicule what they may view as misplaced energies. ”I’ve heard this recently — that embracing the idea of open data and code makes traditional academics uncomfortable.” says Ram, “The concern seems to be that open advocates don’t spend their time being as productive as possible.”
[K] An open-science stance can also add complexity to a collaboration. Kate Ratliff, who studies social attitudes at the University of Florida, Gainesville, says that it can seem as if there are two camps in a field — those who care about open science and those who don’t. “There’s a new area to navigate — ‘Are you cool with the fact that I’ll want to make the data open?’ — when talking with somebody about an interesting research idea,” she says.
[L] Despite complications and concerns, the upsides of sharing can be significant. For example, when information is uploaded to a repository, a digital object identifier (DOI) is assigned. Scientists can use a DOI to publish each step of the research life cycle, not just the final paper. In so doing, they can potentially get three citations — one each for the data and software, in addition to the paper itself. And although some say that citations for software or data have little currency in academia, they can have other benefits.
[M]Many advocates think that transparent data procedures with a date and time stamp will protect scientists from being scooped. “This is the sweet spot between sharing and getting credit for it, while discouraging plagiarism（剽窃）,”says Ivo Grigorov, a project coordinator at the National Institute of Aquatic Resources Research Secretariat in Charlottenlund, Denmark. Hogg says that scooping is less of a problem than many think, “The two cases I’m familiar with didn’t involve open data or code.” he says.
[N]Open science also offers junior researchers the chance to level the playing field by gaining better access to crucial data. Ross Mounce, a postdoc studying evolutionary biology at the University of Cambridge, UK, is a vocal champion of open science, partly because his fossil-based research depends on access to others’ data. He says that more openness in science could help to discourage what some perceive as a common practice of shutting out early-career scientists’ requests for data.
[O]Communication also helps for those who worry about jeopardizing a collaboration, he says. Concerns about open science should be discussed at the outset of a study. “Whenever you start a project with someone, you have to establish a clear understanding of expectations for who owns the data, at what point they go public and who can do what with them,” he says.
[P]In the end, sharing data, software and materials with colleagues can help an early-career researcher to gain recognition — a crucial component of success. “The thing you are searching for is reputation,” says Titus Brown, a genomics（基因组学） researcher at the University of California, Davis. “To get grants and jobs, you have to be relevant and achieve some level of public recognition. Anything you do that advances you presence — especially in a larger sphere, outside the communities you know — is a net win.”

Directions: There are 2 passages in this section. Each 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.
Questions 46 to 50 are based on the following passage.
In the beginning of the movie I, Robot, a robot has to decide whom to save after two cars plunge into the water—Del Spooner or a child. Even though Spooner screams “Save her! Save her!” the robot rescues him because it calculates that he has a 45 percent chance of survival compared to Sarah’s 11 percent. The robot’s decision and its calculated approach raise an important question: would humans make the same choice? And which choice would we want our robotic counterparts to make?
Isaac Asimov evaded the whole notion of morality in devising his three laws of robotics, which hold that 1. Robots cannot harm humans or allow humans to come to harm; 2, Robots must obey humans, except where the order would conflict with law 1; and 3. Robots must act in self-preservation, unless doing so conflicts with laws 1 or 2. These laws are programmed into Asimov’s robots—they don’t have to think, judge, or value. They don’t have to like humans or believe that hurting them is wrong or bad. They simply don’t do it.
The robot who rescues Spooner’s life in I, Robot follows Asimov’s zeroth law; robots cannot harm humanity (as opposed to individual humans) or allow humanity to come to harm—an expansion of the first law that allows robots to determine what’s in the greater good. Under the first law, a robot could not harm a dangerous gunman, but under the zeroth law, a robot could kill the gunman to save others.
Whether it’s possible to program a robot with safeguards such as Asimov’s laws is debatable. A word such as “harm” is vague (what about emotional harm? Is replacing a human employee harm?), and abstract concepts present coding problems. The robots in Asimov’s fiction expose complications and loopholes in the three laws, and even when the laws work, robots still have to assess situations.
Assessing situations can be complicated. A robot has to identify the players, conditions, and possible outcomes for various scenarios. It’s doubtful that a computer program can do that – at least, not without some undesirable results. A roboticist at the Bristol Robotics Laboratory programmed a robot to save human proxies (替身) called “H-bots” from danger. When one H-bot headed for danger, the robot successfully pushed it out of the way. But when two H-bots became imperiled, the robot choked 42 percent of the time, unable to decide which to save and letting them both “die.” The experiment highlights the importance of morality: without it, how can a robot decide whom to save or what’s best for humanity, especially if it can’t calculate survival odds?

Questions 51 to 55 are based on the following passage.
Our world now moves so fast that we seldom stop to see just how far we have come in just a few years. The latest iPhone 6s, for example, has a dual-core processor and fits nicely into your pocket. By comparison, you would expect to find a technological specification like this on your standard laptop in an office anywhere in the world.
It’s no wonder that new applications for the Internet of Things are moving ahead fast when almost every new device we buy has a plug on the end of it or a wireless connection to the internet. Soon, our current smartphone lifestyle will expand to create our own smart home lifestyle too.
All researched agree that close to 25 billion devices, things and sensors will be connected by 2020 which incidentally is also the moment that Millennials（千禧一代） are expected to make up 75 percent of our overall workforce, and the fully connected home will become a reality for large numbers of people worldwide.
However, this is just the tip of the proverbial iceberg as smart buildings and even cities increasingly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with intelligent energy and facilities management.
Online security cameras, intelligent lighting and a wealth of sensors that control both temperature and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business or managing a large building.
We can expect that the ever-growing list of devices, systems and environments remains connected, always online and talking to each other. The big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.
The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount data do deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.
The good news is that most of this technology is already invented. Let’s face it, it wasn’t too long ago that the idea of working from anywhere and at anytime was some form of a distant utopian（乌托邦式的） dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.
It’s time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.

A) The huge capacity of the smartphones people now use.
B) The widespread use of smartphones all over the world.
C) The huge impact of new technology on people’s everyday life.
D) The rapid technological progress in a very short period of time.
52. What can we expect to see by the year 2020?
A) Apps for the Internet of Things.
B) The popularization of smart homes.
C) The emergence of Millennials.
D) Total globalization of the world.
53. What will business owners do when they become aware of the benefits of the Internet of Things?
A) Employ fewer workers in their operations.
B) Gain automatic control of their businesses.
C) Invest in more smart buildings and cities.
