There's a biological reason why a lot of our bad habits are so hard to break-they get1（wire） into our brains."Why are bad habits stronger? You're fighting against the power of an immediate reward." Says Dr. Nora Volkow, director of the National Institute on Drug Abuse and an authority on the brain's pleasure pathway."We all as creatures are behaving that way, to give greater value to an immediate reward as opposed to2is delayed, " Volkow says.How this bit of happiness turns into a habit involves a pleasuresensing chemical named dopamine. It causes the brain3（pursue） that reward again and again strengthening the connection each time-especially when it gets the right hint from your environment.People tend to overestimate their ability to resist temptations around them,thus4（destroy） attempts to give up bad habits. Even scientists who recognize it5show weakness. "I know popcorn is not healthy. But every time I go to the cinema, I have to eat it, " Volkow says. "It's fascinating."A movement to pay people for behavior changes may exploit that connection, as some companies offer employees outright payments for insurance for adopting better habits.6well paying for behavior plays out, researchers say there are still some steps that may help fight your brain's hold7newly-established habits.Repeat, repeat, repeat the new behavior-the same routine at the same time of day. You decide to exercise. Doing it at the same time of the morning, rather than fitting it incasually,8（make） the striatum （终脑皮层） recognize the habit. Therefore, if you don't keep doing it, you will feel frustrated.Exercise itself raises dopamine levels, so eventually your brain will get a feel-goodhit9your muscles protest.Besides, try to reward yourself with10that you really desire. For instance, if you exercise all week or stick to your diet, you could try a fancy restaurant-safer perhaps than a box of cookies because the price inhibits the quantity.二、选词填空（共10小题，每题1分，满分10分）2、【来源】 2018年上海静安区高三二模第31~40题As the increased amount of carton dioxide in the atmosphere, heat stress, longer droughts （干旱）, and more intense rainfalls linked to global warming continue to upset our daily weather, we often forget they also1the quantity, quality, and growing locations of our food. Many foods have already2top spots on the world's "endangered foods" list, indicating their possibility to become scarce within the next 30 years.To start with what is3in many people's lives, we are disappointed to find that coffee plantations in South America, Africa, Asia, and Hawaii are all being threatened by rising air temperatures and erratic （不稳定的） rainfall patterns, which invite disease and invasive speciesto4the coffee plant and beans. The result? Significant cuts in coffee output.And Coffee's culinary cousin, cacao （aka chocolate）, is also suffering stress from global warming's rising temperatures. But for chocolate, it isn't the warmer climate alone that's the problem. Cacao trees actually prefer warmer climates as long as that warmth is paired with high humidityand5rain. However, the problem is that the higher temperatures projected for the world's leading chocolate-producing countries are not expected to be6by an increase in rainfall. Therefore as higher temperatures take more moisture from soil and plants, it's unlikely that rainfall will increase enough to make up for this loss.A notably nutritious plant, the peanut grows best when it gets five months of continuous warm weather and 20 to 40 inches of rain. Anything less and plants won't survive. That isn't good news when most climate models agree that the climate of the future will be one ofthe7including droughts and heatwaves.The world has already caught a glimpse of the peanut's future fate when last year a serious drought across the peanut-growing. Southeastern U.S. led many plants to die. According to a financial report, the dry8caused peanut prices to rise by as much as 40 percent!Finally, in the world of sea, as air temperatures rise, oceans and waterways absorb some of the heat and undergo warming of their own. The result is the9in fish population. Wanner waters also encourage vicious marine bacteria, like Vibrio, to grow and cause illness in humans.And that satisfying "crack" you get when eating crab （蟹） couldbe10as shellfish struggle to build their calcium carbonate （碳酸钙） shells, a result of ocean acidification.A. necessaryB. infectC. extremesD. refreshedE. spellsF. impactG. accompaniedH. sufficientI. shrinkJ. silencedK. earned三、完形填空（共15小题，每题1分，满分15分）3、【来源】 2018年上海静安区高三二模第41~55题"Don't get sick in July!"This is a common concern in teaching hospitals in the U.S. It's driven by the academic calendar: July is when the new interns, fresh out of medical school, start work. In other words, it's when everyone is most1. The theory is that this disadvantage leads to mistakes.So is medical experience good or bad? Well, in most cases, your doctor's experience is very helpful, allowing her to pick up on a（n）2symptom early in a disease process, when machines still can't take a hand. She can also determine the right treatment when your condition falls outside of what is in the3, where newbies get most of their ideas. For many medical treatment, there's a direct connection between physician experience and your treating outcome.In a variety of situation? though, experience can backfire. The reason issimple4. Doctors are humans too andthey5tricks of the mind-like believing that an ineffective treatment really works. In fact, entire fields of research are devoted to understanding why these errors of thought occur. They6from so-called cognitive prejudice that can misleadeven7practitioners into making the wrong decisions.Doctors are usually locked onto a diagnosis early and disregard newand8information. For example, a patient may be diagnosed with a quickly fatal cancer, but then ends up trying various herbal remedies and lives for 30 more years. Instead ofanalyzing the9diagnosis, the patient, and maybe even the doctor, may assume that the herbal remedies cured the cancer.Also, some experienced doctors tend to believe evidence when it supports their previous opinion while subconsciously ignoring information opposing it. Let's say your doctor is pretty certain you have ill digestion and orders a test to10the suspicion, which produces negative result. But she treats you for ill digestion anyway because she was11with the prior diagnosis by experience.In fact, there are clearly many benefits to having a highly experienced doctor, such as technical proficiency. But there may actually be some unexpected benefits to having a less-experienced one too. She may have a more up-to-date education, boundless energy and perhaps is less vulnerable to biases, freed from the same12for years.To safeguard yourself as a patient, one thing you should always do is13. It may not always be possible to determine that your doctor has met with ah unconsciousthinking14. But asking questions does force your doctor to think twiceand15her decision about your case.A. innocentB. productiveC. inexperiencedD. prohibitedA. slightB. objectiveC. complexD. sustainableA. psychologyB. traditionC. realityD. textbookA. psychologyB. educationC. procedureD. priorityA. take advantage ofB. make sense ofC. fall victim toD. play fire withA. springB. departC. benefitD. distinguishA. highly-motivateB. well-seasonedC. deeply-offendedD. wide-eyedA. moderateB. visibleC. conflictingD. permanentA. initialB. toughC. multipleD. privateA. evaluateB. operateC. confirmD. reviseA. preoccupiedB. labelledC. associatedD. concernedA. professional circleB. thinking patternC. academic backgroundD. operating orderA. investigatingB. questioningC. monitoringD. observingA. obstacleB. trapC. horizonD. struggleA. practiceB. accommodateC. justifyD. remove四、阅读理解（共11小题，每题2分，满分22分）4、【来源】 2018年上海静安区高三二模（A篇）第56~59题Last October I was on a diving holiday in the Philippines with seven other advanced divers. I dived off the boat slowly sinking to about 20m.After nearly 45 minutes, the sound of my breathing was drowned out by a low rumble like an engine and I felt deep powerful vibrations （震动） as if a big boat with a propeller was passing overhead. The dive instructor's eyes were wide with confusion too. We both swam next to each other staying close to the side of the reef （礁石） . The situation felt sinister.Then we were enveloped by clouds of white sand that mushmoomed up around us. Could it be a giant turtle （海龟） racing past us? They are normally slow movers so this was very weird behavior. The vibration became so intense that I could feel it in my homes and then the sound turned into a deafening roar. Suddenly, a few meters below us, breaks began forming and the sand was sucked down. That's when I got what it was. The noise was the sound of the earth splintering open and grinding against itself.The instructor and I held hands and looked into each other's eyes. I felt comforted by his presence. I was numb （麻木的） for terror but clear-headed. My body went on high alert, ready to react. But I have no power over whatever this is. The only option is to stay very still and let it do whatever its going to do.It took enormous willpower to resist the urge to swim to the surface, which is not sensible as situation on the surface at that time was ambiguous with potential threats pending. Soon we saw other divers.The sound and vibration lasted only two or three minutes and when they stopped I heard the swoosh of sand falling over the seabed. We all held hands before resurfacing to avoid decompression sickness, which can be fatal. When up, it was a huge relief to see all the divers and we all shared incredulous looks before pulling out our breathing tools and shouting, "What was that? "Back on the boat, we rushed to check the news and confirmed we had witnessed a huge earthquake, measuring 7.2 on the Richter scale. It released more energy than 30 Hiroshima bombs, though it seemed that we were not at the epicenter （震中） . I was high and felt lucky surprisingly not because of my recent survival miracle, but to have experienced nature at its most stunning and its most frightening.(1) How did the author realize that they met with an earthquake?A. By feeling the violent shake under the sea.B. By witnessing a normally-slow turtle quickly moving by.C. By seeing the seafloor crack.D. By checking the news and be informed of the event.(2) Why didn't the author rise to the surface before the vibration stopped?A. Because the instructor gestured him not to rise.B. Because he was numb in body.C. Because he could sense the unclear water situation.D. Because he tried to avoid unexpected danger above.(3) Which of the following statements is TRUE according to the passage?A. At the beginning of the event, a big boat passed by causing big vibration.B. All the divers used the reef as the protection against the violent vibration.C. I felt relieved as the instructor was experienced in handling situations like this.D. Powerless to fight nature, I was tame when under the water.(4) Why did the author feel fortunate on the boat?A. Because he was not at the epicenter of the earthquake.B. Because he finally survived a huge earthquake.C. Because he could witness a rare natural phenomenon.D. Because he didn't suffer from decompression sickness.5、【来源】 2018年上海静安区高三二模（B篇）第60~62题Amazon is presenting to you our weekly bestsellers in the fiction section.Twilight WhispersLinked for years through friendship and intermarriage, the Warren and Whyte families find their charmed world marred when Mark Whyte and his wife Deborah Warren are murdered. Police detectives, hearing about TAL#NBSP dissension of the families, set out to examine the mystique behind their superficial rapport.Katia Morell, daughter of the Whyte's housekeeper, is drawn back to her growing place and is forced to face her life-long love for Jordan Whyte. As many secrets are uncovered, especially about Katia's biological father, the two young people from rival families are encountering fierce family objection in their search for happiness.The New ColossusNellie Bly, blessed with courage and reportage skill, lands two front-page stories on the widely-read newspaper, Joseph Pulitzer's NEW YORK WORLD.Pulitzer is so impressed that he assigns her to murder case confusion the police—the death of Emma Lazaru. Her investigation leads to tense encounters with some powerful and ruthless men of the time, when evils run wild on unregulated upper class. Bly has one real ally: a doctor who uses scientific techniques to establish criminal behavior. As the pieces fall into place, Bly uncovers layers of corruption （腐败） . The essential connection between the murder case and the prevalent greed and darkness of the society finally emerges.The Last Days of NightA young lawyer name Paul Cravath, takes a case that seems impossible to win. Paul's client, George Westinghouse, has been sued by Tomas Edison over a billion-dollar question: Who invented the light bulb and holds the right to power the country?The case affords Paul entry to the heady world of high society—the glittering parties and the dark dealings behind closed doors. The task is beyond daunting. Edison is a dangerous opponent with vast resources at his disposal—private spies, newspapers. Yet this unknown lawyer shares with his famous opponent a compulsion to win at all costs.In obsessive pursuit of victory, Paul receives favors from Nikola Tesla, a brilliant inventor holding the key to defeating Edison.Bones Don't LiePrivate investigator Lance Kruger was just a boy when his father vanished twenty-three years ago. Since then he's lived under the weight of that disappearance for over 20 years—until his father's car is finally dragged out from Grey Lake. It should be a time for closure, except for the skeleton found in the trunk. A missing person case gone cold has become a murder.For Lance, the investigation yields troubling questions about a man he thought he knew. But memories can play dirty tricks. For his partner attorney Morgan, uncovering each new lie comes with a disquieting fear that someone is out there watching, killing every witness tied to this decades-old crime.(1) In which way is The Last Days of Night different from the other three novels?A.

In The Last Days of Night, Paul finally wins the law case because of his client Westinghouse's vast resources at disposal.D. In Bones don't lie, Lance Kruger's father was confirmed by the police as the murdered when Lance was a boy.(3) The underlined word TAL#NBSP dissention is closet in meaning to.A. financial worseningB. the loss of powerC. silenceD. conflict6、【来源】 2018年上海静安区高三二模（C篇）第63~66题If what we did were simply work to live, the reality of our everyday existence would be equivalent to that of stone age man. All of human achievement that makes modern life possible has happened because of the time that has been freed up from the work of everyday survival.For most of the human species on earth man and woman have been occupied with the simple business of staying alive in as much relative comfort as possible. Hunting and gathering, finding or building shelter, defending the little that one has from plunder （抢夺）, surviving long enough to have offsprings of a mature enough age to contribute to the welfare of the group—this was initially the main business of living. It has only been comparatively recently, since the agricultural and industrial revolutions that used emerging technologies to free human beings from the TAL#NBSP drudgery of day-to-day survival, that time has become available to do other than simply survive.However, living to work is a luxury that we should not take for granted, for even now still most of the human race couldn't be blessed with the pearl.When we live to work we enjoy what we are doing, otherwise we wouldn't be doing it. The term "live to work" implies choice. Working to live denotes the exact opposite: anything will do that pays the bills. Anyone in the latter situation will attest to the undesirability of being in such a position. Living to worksuggests exhilaration in one's calling; it summons images of freedom and excitement in the prospect of what each new day will bring, whereas working to live suggests little choice if any. "What do you want to do when you grow up? " is a question with which most children will be familiar, perhaps even bored. It is a question of what even a young adult can often not be sure of until they have had experiences of many different jobs, or at least the ones they thought to try. But to be forced to work at a task that one does not enjoy day after day for survival would be last choice on anyone's list. Enlightened humanity, while acknowledging that some undesirable jobs must be done regardless, would acknowledge that if one is motivated in his work, the work will be so much better accomplished.(1) The underlined word drudgery is closest in meaning to.A. imaginationB. hard laborC. draggingD. familiarity(2) It is implied in the text that human beings.A. have been satisfied by contributing to the welfare of the group.B. stayed alive in much possible comfort for centuriesC. made little progress before the emergence of technologiesD. were addicted to hunting, gathering and building shelters.(3) Which of the following statements is TRUE according to the passage?A. Human achievements facilitating modern life are done during the leisure time freed from survival work.B. The major early business of humans is to seek chances for technological developments.C. In modern society, most people have enough comforts to make individual choices for work.D. Most adults can answer confidently questions concerning what jobs they want to do.(4) The best title for the passage would be.A. Technology, a driving force to push humans ahead.B. Working to live, a basic condition for pleasant living to work.C. Different desires and prospects people have for different kinds of work.D. Working to live or living to work, a choice distinguishing joy from suffering.五、信息匹配（共4小题，每题2分，满分8分）7、【来源】 2018年上海静安区高三二模第67~70题Most people don't need science to appreciate the importance of a mother's love. But to understand how early maltreatment can derail a child's development requires careful study.In a famous research, Harry Harlow had demonstrated that proper psychological and physical development of infants requires nurturing and attention from a parent.1In that research, socially isolated monkey babies that were removed from their mothers were found to be clinging to a cloth-covered surrogate （替代的） mother for comfort.Such experimentations sound cruel. They, however, have.been critical in helping change policies in human orphanages （孤儿院） in the U.S. For centuries some orphanages treated infants equally inhumanely. Despite early evidence that orphanage infants were far more likely to die than others, supporters argued that it didn't matter whether children had "parents" specially devoted to them at the orphanage.2Orphans were supposed to be in positive mental and physical health until adoptive parents were found. Babies, they said, couldn't remember anyway.The harrowing consequences of these theories were most vividly brought to light in Romania in the 1980s and '90s. A ban on abortion （流产） led to a surge in orphanage babies. Simply being fed and changed without individualized affection, some babies present serious problems. Many developed violent behaviors, repetitively rocking or banging their heads. Some were cold and withdrawn or indiscriminately affectionate.3Their head sizes were especially small. They even had problems with attention and compression. The longer these children were left alone, the more damage was seen.The lack of a secure attachment relationship in the early years has destructive consequences for both physical and mental health later in life, with long-lasting effects. The persistence of these effects emphasizes the need to intervene early in life. The Nobel-prize-winning economist James Heckman, has long argued that investing in early childhood education provides a greater return for society than virtually any other type of spending. It is obviously reflected in increased educational success and productivity. The reduced crime, addiction, distress and disorder point to the same theory. Early life conditions critically affect adult life.4Remove it and the harm is great.A. The appropriate feeding and caring styles were greatly rewarded in all aspects.B. It was claimed that simply feeding and changing them would be adequate.C. Some, however, demonstrate little influence with roughly ordinary behavior pattern.D. Maternal attachment plays a fundamental role in shaping who we are.E. Necessities are not just the availability of food and water.F. And they simply didn't grow like normal infants.六、翻译句子（共4小题，每题2分，满分8分）8、【来源】 2018年上海静安区高三二模第71~75题Directions: Translate the following sentences into English, using the words given in the brackets.(1) 听到学校篮球队赢球的消息，我们都很兴奋。

(16 分)中国怎样成了中国人的中国①公元前7500 年左右,中国开始出现农作物和家畜,还有陶器和打磨的石器。

中国是世界上最早的动植物驯化中心之一。

中国广大的幅员和生态的多样性造就了许多不同的地区性文化。

在公元前第四个千年期间,这些地区性文化在地理上扩张,它们开始相互作用,相互竞争,相互融合。

文化多样性地区之间的交流,丰富了中国的文化和技术,而交战的酋长管辖地之间的激烈竞争推动了规模更大、权力更集中的国家的形成。

②虽然中国的南北梯度妨碍了作物的传播,但这种梯度在中国不像在美洲或非洲那样成为一种障碍,因为中国的南北距离较短;同时也因为中国的南北之间既不像非洲和墨西哥北部那样被沙漠阻断,也不像中美洲那样被狭窄的地峡隔开。

倒是中国由西向东的大河(黄河、长江)方便了沿海地区与内陆之间作物和技术的传播,而中国东西部之间的广阔地带和相对平缓的地形最终使这两条大河的水系得以用运河连接起来,从而促进了南北之间的交流。
