A5 Secrets of Web Travel SitesBooking a trip on an online travel site is convenient, but comes with its own set of problems.1. They know who's on a Mac and who's on a PC and who's going to spend more.仔细审题、认真作答．试题习题、尽在百度Last year, US travel research company Orbitz tracked people's online activities to test outwhether Mac users spend more on travel than PC users. On average, Mac users lay out US$20—30 more per night on hotels and go for more stars, according to the Wall Street Journal. As a result, online travel sites show these users more expensive travel options first. To avoid inadvertently paying more, sort results by price.2. Their software doesn't always hook up to the hotel's system.A guaranteed reservation is almost impossible to come by anywhere—but the risk of yourflight or hotel being overbooked increases with third－party providers. The middle－man's software isn't immune to system errors, so always call the hotel or airline to make sure your booking was processed.3. Don't be fooled by packages: Often, they're low－end items grouped together.Ever notice how travel sites recommend a hotel, a rental car, and tour package all in one click? These deals usually feature travel that no one wants, like flights with multiple layovers. Check the fine print.4. You could miss out on loyalty points.Third－party providers can get between you and frequent flyer miles or points. Many hotel loyalty programmes don't recognise external sites, others award only minimum points and exclude special offers, like double points on hotel stays.5. Once your trip is purchased, you're on your own.An online travel agency can't provide assistance the same way an agent can if a flight is cancelled or a room is substandard. Basically, when you arrive at the airport or hotel, you're just another client who booked at the lowest rate.()56. Which of the following is TRUE?A. Third－party providers can ensure your reservation.B. Mac users are likely to spend more money than PC users.C. An online travel agency functions the same as an agent.D. Packages usually provide travelers with satisfactory programmes.()57. What's the purpose of the passage?A. To encourage readers to book a trip on an online travel site.B. To make an advertisement about several travel sites online.仔细审题、认真作答．试题习题、尽在百度C. To convince readers not to book a trip on an online travel site.D. To warn readers of some problems with booking trips online.BWant to add some hours to your day? OK, you probably can't change the fabric of time. But anew study suggests that the way you feel about your goal can change your concept of time and that some simple strategies could make you feel less rushed.In a series of experiments, Jordan Etkin, a professor of marketing at Duke, and her co－authors, Loannis Evangelidis and Jennifer Aaker, looked at what happens when people see theirgoals as conflicting with one another. In one, they asked some participants to list two of their goals that they felt were in conflict, and others simply to list two of their goals. Those who were forced to think about conflicting aims felt more time pressure than those who weren't. In anotherexperiment, the researchers gave participants a similar prompt regarding goal conflict, but this time measured their anxiety levels as well as their attitudes toward time. They found that participants who thought about conflicting goals had more anxiety than those who didn't, and that this, in turn, led to feelings of being short on time.“Stress and anxiety and time pressure are closely linked concepts，” D. Etkin explained. “When we feel more stress and anxiety in relation to our personal goals, that manifests(表现) asa sense of having less time.”Technological advances that allow people to do lots of things at once may increase thefeeling of goal conflict, she said.“I think the easier it is for us to try to deal with a lot of these things at the same time，”she said, “the more opportunity there is for us to feel this conflict between our goals.”She isn't the first to suggest that actual busyness isn't the only thing that can make us feelbusy. At the Atlantic, Derek Thompson wrote that “as a country, we're working less than we did in the 1960s and 1980s”. He offered a number of possible reasons some Americans still feel so overworked, including “the fluidness(不固定性) of work and leisure”. As he put it：“The idea that work begins and ends at the office is wrong. On the one hand, flexibility isnice. On the other, mixing work and leisure together creates an always－on expectation that makes it hard for white－collar workers to escape the shadow of work responsibilities.”And Brigid Schulte writes in her 2014 book Overwhelmed: How to Work, Love, and Play仔细审题、认真作答．试题习题、尽在百度When No One Has the Time that some researchers believe “time has no sharp edges. What often matters more than the activity we're doing at a moment in time, they have found, is how we feel about it. Our_concept_of_time_is,_indeed,_our_reality.”Fortunately, Dr. Etkin and her team did find ways of making us feel better about time—or, at least, of reducing the negative influence of goal conflict. When participants performed a breathing exercise that reduced their anxiety, the impact of such conflict on their perception of time was less pronounced. Reframing anxiety as excitement (by reading the phrase “I am excited！”aloud several times) had a similar effect.Breathing and reframing may not solve everyone's time problems—Ms. Schulte writes thatsome Americans are indeed working more than they used to. She cites the work of the sociologists Michael Hout and Caroline Hanley, who have “found that working parents combined put in 13 more hours a week on the job in 2000 than they did in 1970. That's 676 hours of additionally paid work a year for a family. And that's on top of all the unpaid hours spent caring for children and keeping the house together.”Sometimes, we may feel short on time because we actually are. However, Dr. Etkin believes her findings suggest we may “have the ability to influence our experience of time more than we think we do”．“We're all going to have times in our lives when our goals seem to be in more conflict than others，”she said. But with techniques like the ones her team tested, “we really can help ourselves feel like we have more time.”()58. What makes people feel rushed today?A. Goal conflict.B. High pressure.C. Too much expectation.D. Lack of exercise.()59. Which of the following statements is TRUE according to the passage?A. Most people are having less work to do nowadays.B. People under a lot of stress have a better sense of time.C. Technological advances allow people to feel less stressed.D. The flexibility of work increases white－collar workers' pressure.()60. The underlined sentence “Our concept of time is, indeed, our reality.”means________．A. we should make full use of time仔细审题、认真作答．试题习题、尽在百度B. we value time more than the way we liveC. we can feel better about time if we want toD. we don't have the time to enjoy life in realityC“Over the years the unthinkable has become thinkable and today we sense we are close to being able to alter human heredity(遗传)．”These were the words of David Baltimore of the California Institute of Technology, on December 1st, when he opened a three－day meeting in Washington to discuss the morality and use of human gene editing. Dr Baltimore is an old hand at these sorts of discussions, for he was also a participant in the Asilomar conference, in 1975, which brought scientists together to discuss a safe way of using the then－new technology of recombinant DNA, and whose recommendations influenced a generation of biotechnology researchers.Four decades on, the need for a similar sort of chin－wag has arisen. The InternationalSummit on Human Gene Editing has been held by the national scientific academies of three countries —America, Britain and China. They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line, something Dr Baltimore described as a deep and troubling question. Like those of Asilomar, the conclusions of this meeting will not be binding. But the hope is that, again like Asilomar, a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves, rather than having politicians and civil servants do it for them. The meeting is being held against a backdrop of rapid scientific advance. Since 2012 research into a new, easy－to－use editing tool called CRISPR－Cas9 has blossomed. This technique involves a piece of RNA (a chemical messenger, which can be used to recognise a target section of DNA) and an enzyme(酶) called a nuclease that can snip unwanted genes out and paste new ones in.Public interest was aroused in April, when Chinese scientists announced they had editedgenes in non－viable(无活力的) human embryos, and again in November when British researchers said they had successfully treated a one－year－old girl who had leukaemia(白血病), using gene－edited T－cells. T－cells are part of the immune system that attack, among other things, tumour cells. The researchers altered T－cells from a healthy donor to encourage them to recognise and kill the patient's cancer, to make them immune to her leukaemia drug, and to ensure仔细审题、认真作答．试题习题、尽在百度they did not attack her healthy cells.In another recent development, a firm called Edit as Medicine, which is based in Cambridge, Massachusetts, has said it hopes, in 2017, to start human clinical trials of CRISPR－Cas9 as a treatment for a rare genetic form of blindness known as Leber congenital amaurosis(伯氏先天性黑蒙). Though other companies are already testing gene－editing therapies, these employ older,clunkier forms of the technology that seem likely to have less commercial potential. Moreover, researchers at the Broad Institute, also in Cambridge, said this week that they had made changes to CRISPR－Cas9 which greatly reduce the rate of editing errors —one of the main obstacles to the technique's medical use.On the subject of germ－line editing, Eric Lander, the Broad's head, told the meeting itwould be useful only in rare cases and said it might be a good idea to “exercise caution”before making permanent changes to the gene pool. The need for caution is advice that might also be heeded by those pursuing work in animals other than people, and in plants —subjects not being covered by the summit.()61. Which of the following is TRUE about CRISPR－Cas9?A. It has fewer side effects.B. It can modify human gene.C. It can protect immune system.D. It has less commercial potential.()62. The underlined word “chin－wag”in Paragraph 2 can be replaced by________．A. discussionB. negotiationC. argumentD. comparison()63. What can be inferred from the passage?A. Dr. Baltimore started his research on modifying gene in 1975.B. Scientists' opinions about the use of gene editing are consistent.C. CRISPR－Cas9 has been applied to cure Leber congenital amaurosis.D. More research should be made before the technology comes into wide use.()64. This passage is most probably a ________．A. science fictionB. scientific reportC. conference summaryD. commercial advertisementDBefore the law sits a gatekeeper. To this gatekeeper comes a man from the country who asks仔细审题、认真作答．试题习题、尽在百度to gain entry into the law. But the gatekeeper says that he cannot grant him entry at the moment.The man thinks about it and then asks if he will be allowed to come in sometime later on. “It is possible，”says the gatekeeper, “but not now.”①The gate to the law stands open, as always, and the gatekeeper walks to the side, so the man bends over in order to see through the gate intotheinside.Whenthegatekeepernoticesthat,helaughsandsays:“If_it_tempts_you_so_much,_try_going_inside_in_spite_of_my_prohibition._But_take_note._I_a m_powerful._And_I_am_only_the_most_lowly_gatekeeper._But_from_room_to_room_stand_gat ekeepers,_each_more_powerful_than_the_other._I_cannot_endure_even_one_glimpse_of_the_third.”The man from the country has not expected such difficulties: the law should always be accessible for everyone, he thinks, but as he now looks more closely at the gatekeeper in his fur coat, at his large pointed nose and his long, thin, black Tartar's beard, he decides that it would be better to wait until he gets permission to go inside. The gatekeeper gives him a stool and allows him to sit down at the side in front of the gate. There he sits for days and years. He makes many attempts to be let in, and he wears the gatekeeper out with his requests. The gatekeeper often interrogates him briefly, questioning him about his homeland and many other things, but they are indifferent questions, the kind great men put, and at the end he always tells him once more that he cannot let him inside yet. The man, who has equipped himself with many things for his journey, spends everything, no matter how valuable, to win over the gatekeeper. The latter takes it all but, as he does so, says, “I am taking this only so that you do not think you have failed to do anything.”②During the many years the man observes the gatekeeper almost continuously. He forgets the other gatekeepers, and this first one seems to him the only barrier for entry into the law. He curses the unlucky circumstance, in the first years thoughtlessly and out loud; later, as he grows old, he only mumbles to himself. He becomes childish and, since in the long years studying the gatekeeper he has also come to know the fleas(跳蚤) in his fur collar, he even asks the fleas to help him persuade the gatekeeper. Finally his eyesight grows weak, and he does not know whether things are really darker around him or whether his eyes are merely deceiving him. But he recognizes now in the darkness a ray of light which breaks out of the gateway to the law. Now he no longer has much time to live.仔细审题、认真作答．试题习题、尽在百度Before his death he gathers in his head all his experiences of the entire time up into onequestion which he has not yet put to the gatekeeper. He waves to him, since he can no longer liftup his stiffening body. The gatekeeper has to bend way down to him, for the great difference has changed things considerably to the disadvantage of the man. ③“You are insatiable(不知足的)．”“Everyone strives after the law，”says the man, “so how is it that in these many yearsno one except me has requested entry？”The gatekeeper sees that the man is already dying and,in order to reach his diminishing sense of hearing, he shouts at him, “Here no one else can gain entry, since this entrance was assigned only to you. I'm going now to close it.”④()65. Which can best describe the man from the country?A. Brave but innocent.B. Loyal but ridiculous.C. Tolerant but stubborn.D. Trustworthy but childish.()66.

A close relationship is formed between the gatekeeper and the man.()69. Why is the man from the country eager to have access to the law continuously?A. Because he is anxious to explore the nature of law.B. Because no one can gain entry into the law except him.C. Because the gatekeeper promises him entry into the law.D.

A major function of the family is to socialize new members of a culture. As children are raised in a family setting, they learn to become members ofthe family as well as members of the larger culture. The family provides the model for all other relationships in society. Through the observations and modeling of the behavior of other family members, children learn about the family and society including the values of the culture. Familystructure and their inherent relationships and obligations are a major source of cultural difference. The family is the center of most traditional Asians' lives. Many people worry about their families' welfare, reputation, and honor. Asian families are often extended, including several generations related by blood or marriage living in the same home. An Asian person's misdeeds are not blamed just on the individual but also on the family—including the dead ancestors. Traditional Chinese, among many other Asians, respect their elders and feel a deep sense ofduty toward them. Children repay their parents' sacrifices by being successful and supporting them in old age. This is accepted as a natural part of life in China. In contrast, taking care of aged parents is often viewed as tremendous burden in the United States, where aging and family support are not honored highly.The Vietnamese family consists of people currently alive as well as the spirits of the dead andof the as－yet unborn. Any decisions or actions are done from family considerations, not individual desires. People's behavior is judged on whether it brings shame or pride to the family. Vietnamese children are trained to rely on their families, to honor elderly people, and to fear foreigners. Many Vietnamese think that their actions in this life will influence their status in the next life.Fathers in traditional Japanese families are typically strict and distant. Japanese college students in one study said they would tell their fathers just about as much as they would tell a total stranger. The emotional and communication barrier between children and fathers in Japan appears 仔细审题、认真作答．试题习题、尽在百度very strong after children have reached a certain age.Although there has been much talk about “family values”in the United States, the family is not a usual frame of reference for decisions in U．S. mainstream culture. Family connections are not so important to most people. Dropping the names of wealthy or famous people the family knows is done in the United States, but it is not viewed positively. More important is a person's own individual “track record”of personal achievement.Thus, many cultural differences exist in family structures and values. In some cultures, thefamily is the center of life and the main frame of reference for decisions. In other cultures, the individuals, not the family, is primary. In some cultures, the family's reputation and honor depend on each person's actions; in other cultures, individuals can act without permanently affecting the family life. Some cultures value old people, while other cultures look down on them.—Adapted from R. L. Oxford & R. C. Scarcella, “A Few Family Structures and Values Around the Globe”。

2018年高三数学预测及最后一讲一、填空题：2018年填空题8-14题总体难度过大. 2018年会控制难度，减少3-4道难题，按6道容易题+6道中等题+2道难题的要求命制.填空题只填结果而不要过程，这个结果可以象做解答题那样，由逻辑推理，计算而得到（演绎推理）. 但由于不要过程，也可将一般情形特殊化后再求结果（类比推理)，还可从个别事实中归纳出一般性的结论（归纳推理），所以解填空题的基本策略是要在“准”、“巧”、“快”上下功夫巧；解题的要领是：快——运算要快，力戒小题大作；稳——变形要稳，不可操之过急；全——答案要全，力避残缺不齐；活——解题要活，不要生搬硬套；细——审题要细，不能粗心大意.常用的方法有：①直接法，②特例法，③合理猜想法，④图象法. 数学填空题，绝大多数是计算型(尤其是推理计算型)和概念(性质)判断型的试题，应答时必须按规则进行切实的计算或者合乎逻辑的推演和判断。

解题时，要有合理的分析和判断，要求推理、运算的每一步骤都正确无误，还要求将答案表达得准确、完整. 合情推理、优化思路、少算多思将是快速、准确地解答填空题的基本要求.【解法推介】（一）、直接法这是解填空题的基本方法，它是直接从题设条件出发、利用定义、定理、性质、公式等知识，通过变形、推理、运算等过程，直接得到结果.例1．设,)1(,3)1(j m i b i i m a -+=-+=其中i ，j 为互相垂直的单位向量，又)()(b a b a -⊥+，则实数m = .（二）、特殊化法当填空题的结论唯一或题设条件中提供的信息暗示答案是一个定值时，可以把题中变化的不定量用特殊值特殊值（或特殊函数，或特殊角，特殊数列，图形特殊位置，特殊点，特殊方程，特殊模型等）代替，即可以得到正确结果.例2．在△ABC 中，角A 、B 、C 所对的边分别为a 、b 、c 。

若a 、b 、c 成等差数列，则=++CA C A cos cos 1cos cos .例3.一个四棱锥和一个三棱锥恰好可以拼接成一个三棱柱，这个四棱锥的底面为正方形，且底面边长与各侧棱长相等，这个三棱锥的底面边长与各侧棱长也都相等．设四棱锥、三棱锥、三棱柱的高分别为1h ，2h ，h ，则12::h h h =___________.例4．坐标原点为O ，抛物线22y x =与过焦点的直线交于A 、B 两点，则OA OB ∙=34- . （三）、数形结合法对于一些含有几何背景的填空题，若能数中思形，以形助数，则往往可以简捷地解决问题，得出正确的结果.例5．如果不等式x a x x )1(42->-的解集为A ，且}20|{<<⊆x x A ，那么实数a 的取值范围是 .例6．设等差数列{}n a 的前n 项和为n S ，若410S ≥，515S ≤，则5a 的最大值为________.（四）、等价转化法通过“化复杂为简单、化陌生为熟悉”，将问题等价地转化成便于解决的问题，从而得出正确的结果.例7．不等式23+>ax x 的解集为（4，b ），则a= ，b=例8.下列表中的对数值有且仅有一个是错误的：请将错误的一个改正为lg = ．（五）、归纳猜想法例9．已知()1(1)()1f nf nf n-+=+(n∈N*)，2)1(=f，则f（2018）= _______（六）、几种开放型填空题1：开放型填空题之多选型填空题例10．若干个能唯一确定一个数列的量称为该数列的“基量”。
