We have wins and wehave losses and, occasionally, they are hard to tell apart. Some people understand this instinctively(本能地), while others struggle. For most of us, learning not to do the thing we’re u sed torequires effort and discomfort. However, we should remind ourselves that we sometimes makemean we’ve failed. We need to accept that things will sometimes gomistakes, and that this doesn’twrong.Indeed, failure is part of life.

We’d set up a plan for how he’d get him up outside the shop near his school at 3:30 pm and I believed this was a perfect plan.Unknown to me, very bad weather was on its way and I was unable to warn him to take shelter.With the combination of his dead phone battery and my dead car battery, I was running lateand unable to communicate that to him.

But a dog’s life is much shorter than humans, about 12 toevery dog owner has to go through the heartbreaking moment when their loving pet passes away.Why not make a clone of that dog then? This is the solution offered by a South Korean company, Sooam Biotech Research Foundation. The company has already successfully cloned atleast 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech has introduced its business to UK dog owners as well, offering them dogs that look just like their lost ones.To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died. Meanwhile, another dog is selected to supply an egg. Researchers then replace the DNA inthe egg with that from the skin cell and implant the egg into the womb(子宫)of a female dog. Theegg grows into a puppy over the following two months.The whole process takes less than a day, but it comes at a shockingly high price—around £63,000. But if you can’t afford it now, you can also save the cell in a laboratory and access it ata later date.However, magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect copy of the original one. Just like identical twins of humans, they share the exactly sameDNA but there will still be small differences between them. “The spots on a Dalmatian(斑点狗)clone will be different, for example,”Insung Hwang, head of Sooam Biotech, told The Guardian.Dog owners will also have to accept the fact that personality is not “clone-able”. A part from genes, personality is also determined by upbringing and environment, which are both random elements that cloning technologies simply cannot overcome, Professor Tom Kirkwood at Newcastle University, UK, told The Telegraph.Perhaps bringing our dogs back by cloning is not the best way to remember them after all.relationship with them Kirkwood, a dog owner himself, pointed out, “An important aspect of ouris coming to terms with the pain of letting go.”28. What service does Sooam Biotech Research Foundation offer?A. Making copies of pet dogs.B. Giving pet dogs identical twins.C. Helping dogs give birth to more puppies.D. Helping dog owners love their dogs more.29. Which order is correct in the dog cloning process?a. An egg is taken from another dog.b. A skin cell is taken from the pet dog.c. The egg grows into a puppy in two months.d. The egg is placed in the womb of a female dog.e. The DNA in the egg is replaced by the DNA from the skin cell.A. a→d→b→e→cB. a→e→b→d→cC. b→a→d→e→cD. b→a→e→d→c30. What can we learn about dog cloning from the passage?A. It has not been put into practice until recently.B. It is very popular among US and UK pet owners.C. It might not give the owners an exactly same dog.D. It is very expensive and usually takes half a year to complete.31. What does Kirkwood think of dog cloning?A. He disagrees with it.B. He supports it.C. He is curious about it.D. He thinks it unbelievable.DAre you a procrastinator(拖拉者)? It’s a common problem. And it can be harmful, as previous research has shown that people who procrastinate have higher levels of stress and lowerwell-being, reported the Association for Psychological Science in the US. But a new study hasfound a way to deal with this problem: Be more connected to your future self.Psychologists think that each person believes that they are really two people: “Present Me” needs and desires to those ofand “Future Me”. “People act as if they prefer their current selves’Daphna Oyserman.their future selves,” wrote psychologists Neil Lewis andexactly how Oyserman and Lewis decided to try to find a way to make “Present Me” imagine “Future Me” would feel the night before a big paper was due, though“Present Me” hadn’t started-off event as a number of days away, not months oryet. They made “Present Me” think about a faryears.seemed 16.3 Thinking about events in this way meant that something like a friend’s weddingdays sooner when considered in days rather than months and 11.4 months sooner when consideredin months rather than years.The researchers also tried to find out whether people would take action sooner if they weretold a certain event was happening in X days rather than years. For example, participants imagined they had a newborn child, and that the child would need to go to college in either 18years or 6,570 days. The researchers found those in the “days” condition planned to start savingon.four times sooner than those in the “years” conditiSo if you think of your life in days instead of years, you may get things done quicker.32. What did Oyserman and Lewis intend to do through their study?A. To work on a solution to test if someone is a procrastinator.B. To find out whether human beings usually have two different characters.C. To discover procrastinators are more likely to have a lower sense of well-being.D. To prove it’s helpful to connect our current selves more with future selves.in Paragraph 4 refers to “_________”.33. The underlined part “this way”A. setting up tough deadlinesB. following schedules strictlyC. counting in smaller units of timeD. imagining how your future self will feel34. What helps prevent people from procrastinating?A. Comparing their future selves with present selves.B. Considering their current selves’ needs and desires.C. Thinking about far-off events in days rather than years.D. Marking important events on a calendar as a reminder.35. What does the passage mainly talk about?A. A way to get things done in time.B. The harmful effects of procrastination.C. The reason to overlook future needs and desires.D. The way to reduce stress and improve happiness.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。

第I卷阅读题必考题【一】现代文阅读(9分,每题3分)阅读下面的文字,完成l—3题。

上世纪末,散文创作空前繁荣。

其中最火爆、最活跃的散文形式呈两极化进展:一方面是思辨化、大型化,即所谓“大散文”,如文化散文、思想随笔等;一方面呈情感化、软化、细化趋向,即所谓“小散文”,特点是侧重表现都市生活的细微感受,关怀世俗红尘中自身的瞬间体验。

“小散文”把散文的自由、随意和飘洒发挥到极致,但同时也在一定程度上消解了精深的生命探求,消解了文学的审美性,而呈现出一种所谓的“散文的消费性格”:短短的篇幅,甜甜的语言,浅浅的哲学,淡淡的哀愁。

也有人把它归纳成一种模式——温馨感人的小故事,加上娓娓倾谈的小情调,加上模糊不清的小感悟,给在快节奏、重功利、轻人情的现代生活中奔走的人们一种廉价的抚慰。

同样属于这一类型的,还有所谓“明星写作”。

它因作者本身的广告效应、读者的好奇心理和关于成名的期待与想象而拥有巨大的读者市场。

只是,就整个进展趋势看,“小散文”也好,“明星写作”也好。

轰动的热潮都可不能维持特别久。

相反的,那些表达着浓重的人文精神,表达着审美意识与历史感,深入人的心灵境域,抵选人性深处的思想随笔和文化散文,倒是有着长久的文学生命力。

它们或者采纳平实、自然的话体风格,抒写达观智慧的人生经验,使人感受到冬天炉边闲话、夏日豆棚啜茗的艺术氛围;或者表现为对传统文化的审视与反思,流露着一种浓酽的文化乡愁;或以理性视角、平常心理和世俗语言表选终极性、彼岸性的话题。

文化散文的兴起,有其现实的、社会的根源。

随着改革开放的深入进展,面时全球化的浪潮,加上西方现代主义文学艺术的妨碍,人的主体意识、探究意识、批判意识、超越意识大大增强,审美趣味发生变化,人们的文化观念、生活观念发生了重大变革,文学艺术的含义与功能随之也发生了转换。

AA month ago, I broke a nail. My other nails looked amazing, but now one was a mess. Clearly, there was no point in keeping the others, so I took out the nail scissors to cut them all off.“What are you doing, Mom? “my daughter cried. "Your nails look great! Don't cut them!”“But they're ruined, "I said, waving the broken one in her face.“They are not ruined, "she said. "You still have nine nails left!”I hesitated, with the scissors still in my hand. My nails certainly weren’t perfect anymore, and the opposite of "perfect "is "ruined”, right? I mean, this is how I think about most things: It's all or nothing. Take my finances for example.I can spend weeks being sensible and buying only essential items, such as food for my family. And then one day, I’ll see something expensive that I really like and buy it. Then, I think to myself "Well, I already spent $ 100 on that dress last week, so I may as well spend $50 on this lipstick(口红)” and give up saving entirely. I've thought about why I act this way, but I don't know what causes this behavior. I seem to go from "good " to "complete disaster" in a matter of moments. My brain only sees "perfect" or "disaster", which isextremely unhelpful.We humans are never just good or bad—we are far more complex. We have wins and we have losses and, occasionally, they are hard to tell apart. Some people understand this instinctively (本能地),while others struggle. For most of us,learning not to do the thing we're used to requires effort and discomfort. However, we should remind ourselves that we sometimes make mistakes, and that doesn't mean we've failed. We need to accept that things will sometimes go wrong.Indeed, failure is part of life. We all fall occasionally, and we normally get straight back up. And so, with my daughter’s words ringing in my ears, I decided to keep my nine nice nails. I feel annoyed every time I look at my hands, but I'm determined to live with my choice. It's a perfect exercise in imperfection. Maybe soon, I'll switch off my computer the next time I feel like I might buy something else I don' t need, although I may need my daughter there to guide me again.21. Why did the author want to cut off her nails?A. She got all of them ruined.B. She didn't like long nails at all.C. She didn’t want to have imperfect nails.D. She wanted to prevent them being broken.22. What is the author's problem with her life?A. She is rather crazy about shopping.B. She looks at life in an extreme way.C. She is too careful with her finances.D. She is unwilling to change her mind.23. What does the author think of failure?A. It is just a normal part of life.B. It can help people to be stronger.C. It can completely destroy our life.D. It is something we need to overcome.BMy son Sam is16 and autistic (自闭症的).There’s a lot going on in that beautiful and brilliant mind of his, but even on a good day he can be easily at a loss. Throw in some diagnosed anxiety, an inability to read social cues(信号)and an unexpected change to his daily routine, and you have the way to deal with a very public meltdown(崩溃).It was Sam's very first day at high school. We'd set up a plan for how he'd get hom e: I’d pick him up outside the shop near his school at 3: 30 pm and I believed this was a perfect plan. Unknown to me, very bad weather was on its way and I was unable to warn him to take shelter.With the combination of his dead phone battery and my dead car battery, I was running late and unable to communicate that to him. As a result, he was left alone and extremely frightened. He became very upset outside the shop, exactly where I’d told him to wait.This was when a beautiful older Vietnamese lady not only went to check on him, but took him inside her shop, calmed him down, got my phone number from him and called me.Five years later he continued to go into her shop every afternoon, bought a drink, had a chat and she sent him home with enough bread and rolls to feed a small nation.Sam will graduate this year, and I'm increasingly feeling the need to drop by the shop to let this wonderful lady know that she has saved Sam, and that she has saved me. I’m not sure if I can communicate all of this, but at least I will get to thank her.There are people I will not get to thank, though—the many kind strangers who have been there for Sam. And believe me, if you're wondering if this world is a complete mess right now, I'm here to say that it is not.So I guess this is a love letter to those of you who have helped a stranger out of the goodness of your heart. Please know you are appreciated, that your beautiful heart and kindness are appreciated, and that, perhaps unknowingly, you have made a great difference in someone's life.24. What can we learn about Sam from the first paragraph?A. He is rather slow with his studies.B. He can deal with sudden changes well.C. He has difficulty in dealing with things.D. He tries hard to learn how to read social cues.25. The undefined part "check on " in Paragraph 4 probably means “”.A. discoverB. visitC. recognizeD. examine26. What happened to Sam after his first day at high school?A. He could get on well with his classmates.B. He made good friends with the nice lady.C. He brought the lady some food to thank her.D. He became willing to communicate with others.27. What is the author’s purpose in writing the passage?A. To express her thanks to kind people.B. To remind us all to help autistic people.C. To show how difficult life is for autistic people.D. To tell us how to make a difference in others' lives.CIf you've ever had a dog, you know just how deep a connection you can develop with “man's best friend". But a dog's life i s much shorter than humans, about 12 to 15 years long, which means every dog owner has to go through the heartbreaking moment when their loving pet passes away.Why not make a clone of that dog then? This is the solution offered by a South Korean company, Sooam Biotech Research Foundation. The company has already successfully cloned at least 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech has introduced its business to UK dog owners as well, offering them dogs that look just like their lost ones.To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died. Meanwhile, another dog is selected to supply an egg. Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb (子宫) of a female dog. The egg grows into a puppy over the following two months.The whole process takes less than a day, but it comes at a shockingly high price—around £63,000. But if you can’t afford it now, you can also save the cell in a laboratory and access it at a later date.However, magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect copy of the original one. Just like identical twins of humans ,they share the exactly same DNA but there will still be small differences between them.“The spots on a Dalmatian(斑点狗)clone will be different, for example,” Insung Hwang, head of Sooam Biotech, told The Guardian.Dog owners will also have to accept the fact that personality is not " clone-able". Apart from genes, personality is also determined by upbringing and environment, which are bothrandom elements that cloning technologies simply cannot overcome, Professor Tom Kirkwood at Newcastle University, UK, told The Telegraph.Perhaps bringing our dogs back by cloning is not the best way to remember them after all. Kirkwood, a dog owner himself, pointed out, " An important aspect of our relationship with them is coming to terms with the pain of letting go.”28. What service does Sooam Biotech Research Foundation offer?A. Making copies of pet dogs.B. Giving pet dogs identical twins.C. Helping dogs give birth to more puppies.D. Helping dog owners love their dogs more.29. Which order is correct in the dog cloning process?a. An egg is taken from another dog.b. A skin cell is taken from the pet dog.c. The egg grows into a puppy in two months.d. The egg is placed in the womb of a female dog.e. The DNA in the egg is replaced by the DNA from the skin cell.A. a→d→b→e→cB. a→e→b→d→cC. b→a→d→e→cD. b→a→e→d→c30. What can we learn about dog cloning from the passage?A. It has not been put into practice until recently.B. It is very popular among US and UK pet owners.C. It might not give the owners an exactly same dog.D. It is very expensive and usually takes half a year to complete.31. What does Kirkwood think of dog cloning?A. He disagrees with it.B. He supports it.C. He is curious about it.D. He thinks it unbelievable.DAre you a procrastinator(拖拉者)? It's a common problem. And it can be harmful, as previous research has shown that people who procrastinate have higher levels of stress and lower well-being, reported the Association for Psychological Science in the US. But a new study has found a way to deal with this problem: Be more connected to your future self.Psychologists think that each person believes that they are really two people: “Present Me" and "Future Me". "People act as if they prefer their current selves’ ne eds and desires to those of their future selves, "wrote psychologists Neil Lewis and Daphna Oyserman.Oyserman and Lewis decided to try to find a way to make “Present Me" imagine exactly how "Future Me" would feel the night before a big paper was due, thou gh “Present Me " hadn't started yet. They made "Present Me "think about a far-off event as a number of days away, not months or years.Thinking about events in this way meant that something like a friend’s wedding seemed 16.3 days sooner when considered in days rather than months and 11.4 months sooner when considered in months rather than years.The researchers also tried to find out whether people would take action sooner if they were told a certain event was happening in X days rather than years. For example, participants imagined they had a newborn child, and that the child would need to go to college in either 18 years or 6, 570 days. The researchers found those in the “days” condition planned to start saving four times sooner than those in the “years” condition.So if you think of your life in days instead of years, you may get things done quicker.32. What did Oyserman and Lewis intend to do through their study?A. To work on a solution to test if someone is a procrastinator.B. To find out whether human beings usually have two different characters.C. To discover procrastinators are more likely to have a lower sense of well-being.D.

AA month ago, I broke a nail. My other nails looked amazing, but now one was a mess. Clearly, there was no point in keeping the others, so I took out the nail scissors to cut them all off.“What are you doing, Mom?” my daughter cried. “Your nails look great! Don’t cut them !”“But they’re ruined,” I said, waving the broken one in her face.“They’re not ruined,” she said. “You still have nine nails left!”I hesitated, with the scissors still in my hand. My nails certainly weren’t perfect anymore, and the opposite of “perfect” is “ruined”, right? I mean, this is how I think about most things: It’s all or nothing. Take my finances for example.I can spend weeks being sensible and buying only essential items, such as food for my family. And then one day, I’ll see something expensive that I really like and buy it. Then, I think to myself “Well, I already spent $100 on that dress last week, so I may as well spend $ 50 on this lipstick (口红)” and give up saving entirely.I’ve thought about why I act this way, but I don’t know what causes this behavior. I seem to go from “good” to “complete disaster” in a matter of moments. My brain only sees “perfect” or “disaster”, which is extremely unhelpful.We humans are never just good or bad — we are far more complex. We have wins and we have losses and, occasionally, they are hard to tell apart. Some people understand this instinctively(本能地), while others struggle. For most of us, learning not to d o the thing we’re used to requires effort and discomfort. However, we should remind ourselves that we sometimes make mistakes, and that this doesn’t mean we’ve failed. We need to accept that things will sometimes go wrong.Indeed, failure is part of life. We all fall occasionally, and we normally get straight back up. And so, with my daughter’s words ringing in my ears, I decided to keep my nine nice nails. I feel annoyed every time I look at my hands, but I’m determined to live with my choice. It’s a p erfect exercise in imperfection. Maybe soon, I’ll switch off my computer the next time I feel like I might buy something else I don’t need, although I may need my daughter there to guide me again.21. Why did the author want to cut off her nails?A. She got all of them ruined.B. She didn’t like long nails at all.C. She didn’t want to have imperfect nails.D. She wanted to prevent them being broken.22. What is the author’s problem with her life?A. She is rather crazy about shopping.B. She looks at life in an extreme way.C. She is too careful with her finances.D. She is unwilling to change her mind.23. What does the author think of failure?A. It is just a normal part of life.B. It can help people to be stronger.C. It can completely destroy our life.D. It is something we need to overcome.BMy son Sam is 16 and autistic(自闭症的). There’s a lot going on in that beautiful and brilliant mind of his, but even on a good day he can be easily at a loss.

26.(13分)赵述岛位于中国南海西北部,面积0.22平方公里。

200多位居民生活在岛上,缺水缺电一直是困扰岛上居民生活的主要问题。

以前靠轮船“送水”,后来用柴油机发电淡化海水,但仍未能很好解决岛上饮水问题。

2017年,江苏某公司生产的世界首台“风光储互补智能微电网海水淡化成套设备”建成运转,可日产淡水100吨,供600人一天使用,达到了国家桶装饮用水的标准,结束了当地“淡水贵如金”的历史。

2018年11月,美国加州发生特大山火,造成的保险赔偿或将达到130亿美元。

为防范火灾,在20世纪初,美国森林服务部门制定“火情抑制”政策,即在发现森林火情后,必须于当天上午10点前扑灭。

但近年来,当地林业部门开始采用“受控火烧”来提高耐火森林生境的质量。

所谓受控火烧是专业人员点燃小规模的山火,火焰较低并且在地表缓慢移动。

经过受控火烧,森林冠层火灾发生概率明显降低。

下图为“圣安娜风”示意图。
