考试用时120分钟。

第一部分阅读理解(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从短文后每题所给的A、B、C和D四个选项中,选出最佳选项,并在答题卡上将该项涂黑。

AQuestioning the existence of aliens is something that scientists have done for decades. In fact, most people do believe that aliens exist in some fashion. The main necessities for life are water and some form of energy source. Not surprisingly, there are some planets, exoplanets and moons that fit the bill. Here are several best chances at finding life in the universe.◆TRAPPIST-1TRAPPIST-1 is a planetary system a few dozen light-years away, whose discovery was announced in early 2017. This system consists of seven Earth-like exoplanets orbiting an "ultra-cool" star, and it is one of our shots at finding possible life beyond our own solar system.◆TitanTitan is the largest moon of Saturn, the sixth planet from our Sun. This moon could potentially harbor life but possibly not in the sense that we think. Titan does not exactly fit the description of being in a typical habitable zone.Titan has water, and it has liquid. It just doesn't have liquid water. The water on this moon is completely solid because of the extremely cold temperature.◆EuropaEuropa is one of Jupiter's moons here in our own solar system. It is another candidate due to its potential to hold liquid water. Europa is thought to have all the necessities for life including water, energy sources, and the right chemical build-up.◆MarsThe Red Planet, the fourth from the Sun, is probably one of the most talked-about potential candidates for extraterrestrial(地球外的) life and even for human colonization. Despite some different voices, finding extraterrestrial life on Mars really is a serious possibility.We know by now that we won't find little green men or any intelligent form of life that we understand. However, there is evidence that there was and may still be microscopic life on the small red planet.1. The common point of these celestial bodies is that _______.A. solid water exists on them respectivelyB. life might exist on each of themC. they all contain liquid waterD. each of them has living things on it2. Which celestial body could have life different from human imagination?A. TRAPPIST-1.B. Titan.C. Europa.D. Mars.3. Which of the following statements is TRUE?A. Europa is the most talked-about potential candidate for extraterrestrial life.B. TRAPPIST-1 is the only body that contains life beyond the solar system.C. All the scientists do believe that aliens exist in some manner.D. There is proof that life existed on the celestial body Mars.BAbout a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. “I want to apply to work with you at Facebook,” she said. “Instead of recommending myself, I wan t toask you: What is your biggest problem, and how can I solve it?”My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for th emselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.4. Why did Lori make the call?A. She helped Facebook to solve the biggest problem.B. She wanted to make a business deal with Facebook.C. She tried to ask for a pay rise in Facebook.D. She wanted to become an employee in Facebook.5. What impressed “I” by Lori?A. Lori was good at running recruiting.B. Lori attached great importance to Facebook’s needs.C. Lori jumped in Facebook with no adequate experience.D. Lori was skilled in marketing at eBay.6. What can we infer from the passage?A. Now all people don’t tend to climb the ladder.B. None on the ladder can enjoy the great views.C. Jungle gyms offer limited exploration for employees.D. A pregnant woman, jobless, benefits little from the jungle gyms.7. What is the best title of the passage?A. It’s a Jungle Gym, Not a Ladder.B. Facebook’s Biggest Problem.C. Applying for a Job in Facebook.D. A Jungle Gym is Better than a Ladder.CCareers in zoology are extremely varied and unique, and can provide incredible learning and work opportunities for anyone devoted to animal studies and welfare. Zoology, or the study of animals, is a wide field with many specialties, including research, conservation, veterinary (兽医的) medicine, and the care of animals. For people with a love of animals and some training, dreams of careers in zoology may come true.Some careers in zoology focus on research and scientific studies. These careers may allow those with a good theoretical science background to develop and run studies that improve human understanding of the animal world. Research in zoology can help create safer and more effective products for animals or can teach humans more about animal behavior in order to aid in conservation, breeding programs, and habitat preservation.Careers in zoology that focus on conservation attach great importance to the continued survival and increased protection of animal species. Conservationists may work with political groups or governments to help make laws to protect and preserve animals, or may work in the field gathering information on potential threats to the health of global ecosystems. Someconservationists work in educational fields, trying to improve human efforts to save animals from extinction.Animals are subject to illness and injury, and some careers in zoology help to create a safe, stable animal population. Veterinary medicine is an important specialty field, and may take several years of intensive training to qualify as a certified veterinarian. While many veterinarians focus on the small-animal practice of domestic pets, vets in rural areas often work with large farm animals and more adventurous veterinarians may work with exotic species in zoos and wildlife preserves. .Humans love to observe animals, and modern-day zoos and wildlife preserves help meet that interest while providing facilities to assist with conservation programs. Zoology careers in zoos can range from overseeing breeding programs, to creating the proper diet for a deer, to cleaning the tiger’s cage. Many volunteer and entry-level jobs are available for people that love animals.8. What is the purpose of researching on animals in zoology?A. To help governments make laws.B. To improve researchers’ scientific knowledge.C. To create safe and effective products for humans.D. To educate people to protect animals.9. What can careers in zoology that focus on veterinary medicine help?A. Better understand animals.B. P rotect animals’ health.C. C lean the animals’ cages.D. Increase the number of animals.10. Which of the following shows the structure of the whole passage?(P1=paragraph 1; P2= paragraph 2; P3= paragraph 3; P4= paragraph 1; P5= paragraph 5;)11. What does the passage mainly present?A. V olunteers’ passion for zoology.B. A new idea of careers in zoology.C. Different types of careers in zoology.D. Effective measures of animal protection.DNEW YORK-A massive winter storm paralyzed much of the US East Coast on Thursday and Friday, dumping as much as 46 centimeters of snow from the Carolinas to Maine. It also caused flooding on the streets of Boston due to swelling storm tides, forced the cancellation of nearly 5,000 flights and closed businesses, offices and schools.Some meteorologists (气象学家) classified the storm as a "bomb cyclone" for its sharp drop in atmospheric pressure would be followed immediately by a blast of cold air that could break records in more than two dozen cities and bring wind chills as low as -40℃during the weekend.From Baltimore, Maryland, to Caribou in Maine, efforts were underway to clear roadways of ice and snow as wind chill temperatures were to plunge during the day, reaching -40℃in some parts after sundown, according to the National Weather Service.Utility companies across the East worked to repair downed power lines early on Friday as about 21,000 customers remained without electricity, down from almost 80,000 the day before, and issued warnings that temperatures may become dangerously low."If the temperature in your home begins to fall, we recommend taking shelter elsewhere until service can be restored. You can find warming centers by contacting local authorities," National Grid power company, which serves Massachusetts, said on Twitter.Airlines canceled 4,000 flights on Thursday and hundreds more on Friday, according to, an online tracking service.Mayor Bill de Blasio said it could feel like -30℃on Friday and Saturday nights with the wind chill. "This is a serious, serious storm, and may be the most severe in 2018," he said at a news conference.New York Governor Andrew Cuomo declared a state of emergency for the southern part of the state, while New Jersey Governor Chris Christie declared a state of emergency for several counties.12.Which of the following is NOT the consequence of the massive winter storm?A.Breakdown of the US coastB.Flooding in Boston.C.Cancellation of nearly 5,000 flights.D.Closure in business, offices, and schools.13.Why did some meteorologists classify this winter storm as “bomb cyclone”?A.Because it will cause changeable atmospheric pressure.B.Because the scale of this storm could break records in lots of cities.C.Because of the deadly and destructive effects of this storm.D.Because of the extremely cold air and the wind chills in this storm.14.Which of the following best explains the underlined word “plunge” in P3?A. decline steadilyB. drop dramaticallyC. fluctuate violentlyD. fall moderately15.About the rescue work, which of the following statements is INCORRECT?A.People were making great efforts to rid roadways of ice and snow.B.About 101 thousand people were left without electricity on Thursday.C.Residents can stay in warming centers until heating service is restored.D.Aviation service hasn't been brought back to normal yet until Friday.第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项, 并在答题卡上将该项涂黑。

29.(10分,除特殊说明外,每空2分)
(1)有氧呼吸(第二阶段)生成二氧化碳(Cl8O2),二氧化碳(Cl8O2)再参与暗反应(光合作用)生成有机物(CH218O) [共4分,“有氧呼吸(第二阶段)”、“二氧化碳(Cl8O2)”、“暗反应(光合作用)”、“有机物(CH218O)”为给分点,漏答1项或错答1项即扣1分,扣完为止] 小于0
(2)A TP的合成需要原料ADP,Pi,能量。

(1分)植物细胞中有ADP,Pi,无氧呼吸第一阶段有少量能量释放出来,所以可以合成少量A TP,(2分)无氧呼吸第二阶段没有能量产生,因此没有ATP生成(1分)。

[共4分,“原料ADP,Pi,能量(1分)、”、“第一阶段释放少量能量(2分)”、“第二阶段没有能量释放(1分)”为给分点,漏答1项或错答1项即扣对应分,扣完为止] (共4分)
30.(9分,除特殊说明外,每空2分)
(1)大脑皮层(2分)
(2)皮肤毛细血管舒张和通透性增加,(1分)血浆中蛋白质和液体渗出,(1分)引起组织间隙液体增多。

(1分)[共3分,“毛细血管舒张和通透性增大”、“蛋白质和液体渗出”、“组织液增多”为给分点,漏答1项或错答1项即扣1分,扣完为止] (共3分)
①通过刺激皮肤冷感受器,引起血管收缩,改变血管通透性,达到止血、减轻水肿及渗出作用;
②解除充血肿胀压迫神经所致的疼痛。

[共2分,“血管收缩”、“缓解肿胀压迫神经所致的疼痛”为给分点,漏答1项或错答1项即扣1分,扣完为止](2分,答对一项得1分)(言之有理可酌情给分)
(3)②阻断神经冲动的产生和传递[补充答案:抑制神经递质的释放](其他合理的答案酌情给分)(2分)
31.(10分,除特殊说明外,每空2分)
(1)抵抗力营养结构变简单,自我调节能力降低
(2)生产者就地
(3)生态系统所具有的保持或恢复自身结构和功能相对稳定的能力[共2分,“保持或恢复”、
“结构和功能”为给分点,漏答1项或错答1项即扣1分,扣完为止]
32.(10分)
(1)实验思路:选择①×②杂交组合,分别得到F1和F2,(2分,杂交组合正确得1分,分别得到F1和F2得1分)
预期实验结果和得出结论:若杂交组合的F2中出现三种表现型,且比例为1∶2∶1,则可确定这二对等位基因位于一对染色体上;若出现其他结果,则可确定这两对等位基因不是位于一对染色体上。

[共3分,“F2中出现三种表现型”、“比例为1∶2∶1”、“结论正确且合理”为给分点,漏答1项或错答1项即扣1分,扣完为止]
(2)实验思路:选择③×④杂交组合进行正反交,观察F1雄性个体的表现型。

(2分,杂交组合正确得1分,观察F1雄性个体的表现型得1分)
预期实验结果和得出结论:若正交得到的F1中雄性个体与反交得到的F1中雄性个体均为有眼刚毛,则证明这两对等位基因都位于XY的同源区段。

若出现其他结果,则可确定这两对等位基因不是都位于XY的同源区段。
