| Anthropologists believe wisdom teeth, or the third set of molars, were the evolutionary answer to our ancestor’s early diet of coarse, rough food ⎯ like leaves, roots, nuts and meats ⎯ which required more chewing power and resulted in excessive wear of the teeth. The modern diet with its softer foods, along with marvels of modern technologies such as forks, spoons and knives, has made the need for wisdom teeth nonexistent. As a result, evolutionary biologists now classify wisdom teeth as vestigial organs, or body parts that have become functionless due to . |

(A)Shortly after the accidental discovery, engineers at Raytheon went to work on Spencer's new idea, developing and refining it to be of practical use. (B)Dr. Percy Spencer was working as an engineer with the Raytheon Corporation at the time, when he discovered something very unusual one day while working on a radar-related research project. While testing a new vacuum tube known as a magnetron, he discovered that a candy bar in his pocket had melted. (C)Intrigued as he was, Spencer decided upon further experimentation. Later on, having pointed the tube at such objects as a bag of popcorn kernels and an egg, with similar results in both experiments (the popcorn popped and the egg exploded), he correctly concluded that the observed effects in each case were all attributed to exposure to low-density microwave energy. |

| To "win hands down" which means to "win easily" or "win with little or no effort" has ①its origins in horse racing. In a close, photo-finish race, a jockey ②typically strikes his horse with a bat or the reins to force it to maintain or increase speed. When the horse is leading by several lengths and a win is assured, the jockey will usually cease striking the horse or let the reins ③go loose: In effect, he puts his "hands down." The expression ④was appeared in the mid-19th century; by the end of the century, it was being used outside of horse racing to mean "with no trouble at all." |
어법상 옳지 않은 것은 "was appeared"로, "appeared"로 고쳐야 한다.
"appear"(나타나다)는 목적어를 취하지 않는 자동사이므로 수동태로 쓸 수 없다. "The expression appeared in the mid-19th century"가 올바르다.

| If a black hole has a non-zero temperature ― no matter how small ― the most basic and well-established physical principles would require it to emit radiation, much like a glowing poker. But black holes, as everyone knows, are black; they supposedly do not emit anything. This was the case until Hawking, in 1974, discovered something truly amazing. Black holes, Hawking announced, are not completely black. If one ignores quantum mechanics and invokes only the laws of classical general relativity, then as originally found some six decades previously, black holes certainly do not allow anything ― not even light ― to escape their gravitational grip. But the inclusion of quantum mechanics modifies this conclusion in a profound way, and Hawking found that black holes do emit radiation, quantum mechanically. |

The main killers were Old World germs to which Indians had never been exposed, and against which they therefore had neither immune nor genetic resistance. ①Smallpox, measles, influenza, and typhus competed for top rank among the killers. ②For example, in 1837 the Mandan Indian tribe, with one of the most elaborate cultures in our Great Plains, contracted smallpox from a steamboat traveling up the Missouri River from St. Louis. ③The Mandan survived mainly by hunting, farming and gathering wild plants, though some food came from trade. ④The population of one Mandan village plummeted from 2,000 to fewer than 40 within a few weeks. |

| Most of the world's great cities have grown randomly, little by little, in response to the needs of the moment; very rarely is a city planned for the remote future. The evolution of a city is like the evolution of the brain: it develops from a small center and slowly grows and changes, leaving many old parts still functioning. There is no way for evolution to remove _____________________________ and replace it with something of more modern manufacture. The brain must function during the renovation. That is why our brain stem is surrounded by the R-complex, then the limbic system and finally the cerebral cortex. The old parts are in charge of too many fundamental functions for them to be replaced altogether. So they wheeze along, out-of-date and sometimes counterproductive, but a necessary consequence of our evolution. *R-complex: (두뇌의) R영역 **limbic system: (두뇌의) 변연계 ***cerebral cortex: 대뇌피질 |

| Umpires and other sports officials are the decision-makers and rulebook enforcers whose word is law on the field of play. Such authority comes with heavy responsibility to match. Sports officials must be unbiased masters of the rules and have thick skins. They must keep control of the conduct of games at all times, be good communicators, and stay cool in situations that can quickly grow heated ― both on the field and in the stands. For every winner in sports there is a loser, of course, and the outcome may ride on a few crucial calls. Was that three-and-two pitch a ball or a strike? Was that last-second basket a buzzer-beater or not? While instant replay provides a fallback in professional and big-time college sports, officials at other levels are on their own. The stakes can be higher than just one game. High school athletes may hope for college scholarships, and key calls against them could hurt their chances when scouts are on hand. As one veteran high school official put it, “You never know who’s in the stands.” ⇓

| Fifty years ago, bees lived healthy lives in our cities and rural areas because they had plenty of flowers to feed on, fewer insecticides contaminating their floral food and fewer exotic diseases and pests. Wild bees nested successfully in undisturbed soil and twigs. (A), bees have trouble finding pollen and nectar sources because of the extensive use of herbicides that kill off so many flowering plants among crops and in ditches, roadsides and lawns. Flowers can be contaminated with insecticides that can kill bees directly or lead to chronic, debilitating effects on their health. (B), with the increase in global trade and transportation, blood-sucking parasites, viruses and other bee pathogens have been inadvertently transmitted to bees throughout the world. These parasites and pathogens weaken bees' immune systems, making them even more susceptible to effects of poor nutrition from lack of flowers, particularly in countries with high agricultural intensity and pesticide use. |

| Sea snakes are some of the most venomous creatures on Earth. Their venom is far deadlier than the venom of coral snakes, rattlesnakes, or even king cobras. Sea snakes use their venom to kill the fish they eat and to defend themselves against predators. It’s not necessarily a good thing, however, for a sea snake to use its venom to defend itself. Venom can take a lot of energy to make-energy that could be used for growing or hunting. (A) , the more often a sea snake or other venomous animal is attacked, the more likely it is to get hurt-even if it can defend itself. Like coral snakes, many sea snakes solve this problem by warning predators up front. (B) , the yellow-bellied sea snake has bright, splashy colors that tell predators not to try anything. Over millions of years, predators have evolved to pay attention to this warning. Only a few kinds of sharks and sea eagles dare attack sea snakes. This keeps sea snakes from constantly having to defend themselves and increases their chances of survival. |

| Despite what you might think, _____________________, according to research by psychologist Richard Wiseman. Instead, it's a result of the way lucky people think and act ⎯ which means that anyone can learn to be lucky! For instance, Wiseman found that lucky people always take notice of what's going on around them and stay open to new experiences and opportunities. Meanwhile, unlucky people tend to be tenser and too focused on certain tasks, which stops them from noticing opportunities they aren't explicitly looking for. So, next time you're heading to a party, don't go in with a goal in mind(no matter how much you want to attract someone). Instead, take things as they come and you never know what might happen.

- "luck brings you closer relationships": 새 친구를 사귈 수도 있다는 말은 결과의 예일 뿐 운의 본질에 대한 설명이 아니다.
- "luck can't be obtained at any costs": 누구나 운을 배울 수 있다는 지문과 반대다.
- "luck is the most precious asset for a person": 운의 가치에 대한 내용은 없다.
| Coral reefs are some of the most diverse and valuable ecosystems on Earth. Coral reefs support more species per unit area than any other marine environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be another 1 to 8 million undiscovered species of organisms living in and around reefs. is considered key to finding new medicines for the 21st century. Many drugs are now being developed from coral reef animals and plants as possible cures for cancer, arthritis, human bacterial infections, viruses, and other diseases. Storehouses of immense biological wealth, reefs also provide economic and environmental services to millions of people. Coral reefs may provide goods and services worth $375 billion each year. This is an amazing figure for an environment that covers less than 1 percent of the Earth’s surface. |
빈칸에는 "This biodiversity"(이 생물 다양성)가 들어간다.
앞 문장들이 산호초에 수많은 생물 종과 미발견 종이 산다는 종의 다양성을 설명하고, 뒤 문장이 산호초 동식물에서 신약이 개발되고 있다고 하므로 이 다양성이 신약 발견의 열쇠라는 흐름이다.
- "Their beauty": 산호초의 아름다움은 지문에 언급되지 않는다.
- "Survival skill of coral reefs": 산호초의 생존 기술은 다루지 않는다.
- "Food chain": 먹이사슬은 신약 개발과 연결되지 않는다.
| Dear Charles, It was a pleasure having lunch with you yesterday. I am very interested in the new household product you mentioned and how I might work with you develop it. I have seen nothing like it advertised in any of the trade journals, so it may be an original, one-of-a-kind product. If so, you will want to move fast to register it to protect your intellectual property rights in it. Let me know if you want to pursue this and I will have our patent associate contact you with a proposal. Let's get together again soon. Until then, Frank |
글의 목적은 새로 개발한 가정용품의 특허등록을 제안하는 것이다.
Frank는 그 제품이 "original, one-of-a-kind product"(독창적이고 유일한 제품)일 수 있으니 "register it to protect your intellectual property rights"(지식재산권 보호를 위해 등록)하라고 권하고, 원하면 "patent associate"(특허 담당자)가 제안서를 갖고 연락하겠다고 한다.
- 새로 구입한 가정용품 환불: 구매나 환불 이야기는 없다.
- 새로 개발한 가정용품 구매 요청: 개발 협력과 등록을 말할 뿐 구매를 요청하지 않는다.
- 새로 개발한 가정용품 표창: 상을 준다는 내용은 없다.
| I have always taught my children that politeness, learning, and order are good things, and that something good is to be desired and developed for its own sake. But at school they learned, and very quickly, that children earn Nature Trail tickets for running the quarter-mile track during lunch recess. Or Lincoln Dollars for picking up trash on the playground or for helping a young child find the bathroom ⎯ deeds that used to be called 'good citizenship.' Why is it necessary to buy the minimal cooperation of children with rewards or treats? What disturbs me is the idea that good behavior must be reinforced with incentives. Children must be taught to perform good deeds for their own sake, not in order to receive stickers, stars, and candy bars. |
필자의 주장은 아이들이 보상 없이도 선행하도록 교육해야 한다는 것이다.
필자는 좋은 행동을 보상(incentives)으로 강화해야 한다는 생각이 불편하다고 하며, 마지막 문장 "Children must be taught to perform good deeds for their own sake, not in order to receive stickers, stars, and candy bars"로 주장을 분명히 한다.
- 예절 교육을 잘 받아야 한다: politeness는 필자가 가르친 가치의 하나일 뿐, 핵심은 보상 없는 선행이다.
- 금전적·물질적 보상이 아이를 망친다: 아이를 망친다고까지 말하지 않으며, 선행 자체를 위한 교육을 강조한다.
- 적절한 칭찬이 필요하다: 보상과 강화를 비판하는 지문의 취지와 반대다.
| Lead is a naturally occurring toxic metal found in the Earth’s crust. Its widespread use has resulted ①in extensive environmental contamination, human exposure and significant public health problems in many parts of the world. Young children are particularly vulnerable to the toxic effects of lead and can suffer profound and permanent ②adverse health effects, particularly affecting the development of the brain and nervous system. Lead also causes long-term harm in adults, including ③decreased risk of high blood pressure and kidney damage. ④Exposure of pregnant women to high levels of lead can cause miscarriage, stillbirth, premature birth and low birth weight, as well as minor malformations. |
문맥상 적절하지 않은 것은 "decreased"(감소한)로, "increased"(증가한)로 고쳐야 한다.
"Lead also causes long-term harm in adults, including …"은 납이 성인에게 주는 장기적 해악을 나열하므로 고혈압과 신장 손상의 위험이 커진다(increased risk)고 해야 한다.
- "in": "result in"(~을 초래하다)으로 광범위한 환경 오염을 초래했다는 뜻이 맞다.
- "adverse"(해로운): 어린이의 뇌·신경계 발달에 미치는 해로운 건강 영향을 가리켜 맞다.
- "Exposure"(노출): 임신부가 높은 농도의 납에 노출되면 유산 등을 일으킨다는 뜻에 맞다.
