In order for that to happen, you need to do two very simple things: put yourself in such situations that you can experience happiness there, and then find a way to savour the experience and let it sink into you.To put yourself in the position of experiencing happiness every day, Lahna Catalino, Ph.D., at the University of California, San Francisco, recommends an approach called “prioritizing positivity”—organizing your daytoday life on purpose so that it contains situations which naturally give rise to positive emotions. It involves both carving out time in your daily routine to do things that you really love and heavily weighing the positive emotional consequences of major life decisions, like taking a new job, and you will regularly find yourself.Then how can we find a way to savour the happy experience and let it sink into you? Here is what psychologist Rick Hanson, the author of Buddha's Brain explains.Let a good fact become a good experience.Often we go through life and some good thing happens—a little thing, like we checked off an item on our To Do list, w e survived another day at work, the flowers are blooming, and so forth. Hey, this is an opportunity to feel good. Don't leave money lying on the table: Recognize that this is an opportunity to let yourself truly feel good.Really enjoy this positive experience.Practice what any school teacher knows: If you want to help people learn something, make it as intense as possible—in this case, as felt in the body as possible—for as long as possible.When sinking into this experience, sense your intention that this experience is sinking into you.Sometimes people do this through visualization, like by sensing a golden light coming into themselves or a soothing balm inside themselves. You might imagine a jewel going into the treasure chest in your heart—or just know that this experience is sinking into you, becoming a resource you can take with you no matter where you go.It might seem a little cliche(陈词滥调) to say “stop and smell the roses，”but it's moments like those that can be stored in your happiness bank and withdrawn later. Living a happy life can be assimple as accepting the happiness that's already around you. If you want more, it's ok to go out andReally enjoy the positive experience as long as possib。

Is it the price you see on the gift receipt? Or is it the look on the recipient’s face when they receive it that determines the true value? What gift is worth the most?This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood, I felt that this was a gift that my father wouldtruly appreciate.Christmas soon arrived. The minute I saw the look on my dad’s face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.56. The idea for a special gift began to form when the author was _________.A. doing shoppingB. having a debaterC. reading a messageD. leaving for Wyoming57. The author’s inspiration for the gift came from _________.A. a photo of a flowerB. a story about a kidC. a call from the motherD. a text about Christmas58. The underlined word “it” in Paragraph 3 refers to a poem by _________.A. the fatherB. the authorC. William BlakeD. Edgar Allan Poe59. The author made the gift by _________.A. searching for the poems onlineB. drawing the background by handC. painting the letters in three colorsD. matching the words with pictures60. What is the main purpose of the passage?A. To show how to design images for gifts.B. To suggest making gifts from one’s heart.C. To explain how computers help create gifts.D. To describe the gifts the author has received.阅读表达I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day. But I became invisible, absent from the conversation.The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Recently I was in a car with three friends. The driver told us to be quiet because he could not hear the person on the other end of his cell phone. There we were, four friends going down the highway, unable to talk to one another because of a tool designed to make communication easier.Why is it that the more connected we get, ________________________ ?

Or being relieved that voice mail picked up because I didn’t really have time to talk.

高一语文限时训练(六)
高一语文限时训练（六）一、现代文阅读（本题共4小题，16分）阅读下面的文字，完成下面小题。
追我魂魄（节选）云杉电话是资料室的管理员打来的。
“那张照片的作者找到了，他叫穆易。
”“是不是去柬埔寨的那个穆易？嗨，要他的照片可真难。
”管理员在电话那头笑了起来。
“他就在这儿，你来一趟吧！”资料室在地下室。
宽阔深邃的大厅里排满了20世纪60年代那种深黄色的木柜。
一上了年纪的男人站在书柜的中间，和管理员说话。
我站在那儿等了一会儿，从塑料夹子里取出那张照片，我猜想这个人就是穆易。
他转脸看见了我。
他脸上有一种沧桑的、聪颖的神情，这种特别的气质使他与众不同。
如果一个人经历了几十年里发生的几乎所有战争，他一定会有什么变化。
“这是1942年拍的，没错。
”他把照片翻过来，上面有一行变成黄色的钢笔字：培蕊，1942年5月，太行山，年17岁。
①“这些字是，我写的。
”我们走到书柜后面，那里有一张书桌和两张单人沙发。
“她是鲁艺的文工团员，唱歌的。
”他非常肯定地说。
“如果照片已经无法送给本人，我就会记下来姓名、地址等等。
”培蕊，1942年5月，太行山，年17岁。
这些字迹确实散发着伤感的气息。
“我是那年5月遇见她的，当时我是晋察冀军区的报道员，去太行山采访，回来的时候在山下遇见了鲁艺文工团的一大群女孩子。
其中一个对我说：‘嗨，记者同志，给我留个影吧！’她就是培蕊。
很年轻，她回头招呼别的人，②那些人笑着不过来，她也在笑，她的笑容很灿烂。
我的底片已经用完了，但是还有我们称为‘尾巴’的一小块空白，我决定试一试。
我问她：‘要是照片洗出来了，怎么给你？’她笑着招招手说：‘到前线见！’我也说：‘前线见！’那时我们非常年轻，非常快乐，觉得生命很长，③而且会充满许多快乐的相见。
”“她死了，是吗？”“你听说过八路军总部被袭事件吗？”穆易看见我一脸茫然，就说，“1942年5月，侵华日军总司令冈村宁次调集了三万精锐部队包围了八路军总部，被包围的人都是机关、后勤、学校、文艺团体的人员，培蕊的剧团也在其中。

Though they live in different times, they still have something in common.BEight years before his death in 1986, Alfred Nobel was surprised to read an obituary(讣告) inthe local newspaper. This was a strange obituary, for it told Alfred Nobel, the man who was readingit, that he was dead. The newspaper had confused Alfred with his brother, Ludwig, who had recentlydied.Nobel was shocked to read that he had passed away, and he was even more annoyed by the titleof the obituary: The Merchant of Death Is Dead. Alfred was a very rich and successful armaments manufacturer.(武器制造商)。

高二语文阅读限时训练(解析版)第6课 《兼爱》
第6课兼爱一、立足文本（一）阅读下面文言文，回答小题。
兼爱①天下之人皆不相爱，强必执弱，富必侮贫，贵必敖．贱，诈必欺愚。
凡天下祸篡怨恨，其所以起者，以不相爱生也。
是以仁者非之．。
②既以非之，何以．易之？子墨子言曰：以兼相爱、交相利之法易之。
然则兼相爱、交相利之法将奈何哉？子墨子言：视人之国若视其国，视人之家若视其家，视人之身若视其身。
是故诸侯相爱则不野战，家主相爱则不相篡，人与人相爱则不相贼，君臣相爱则惠忠，父子相爱则慈孝，兄弟相爱则和调。
凡天下祸篡怨恨可使毋起者．，以相爱生也。
是以仁者誉之。
③然而今天下之士君子曰：“然！乃若兼则善矣；虽然，天下之难物于故也（1）。
”子墨子言曰：天下之士君子，特不识其利、辩其故也。
今若夫攻城野战，杀身为名，此天下百姓之所皆难也。
若君说．之，则士众能为之。
昔者．晋文公好士之恶衣，故文公之臣皆牂羊之裘（2），韦以带剑，练帛之冠，入以见于君，出以践于朝。
是其故何也？君说之，故臣为之也。
昔者楚灵王好士细要（3），故灵王之臣皆以一饭为节，胁息（4）然后带，扶墙然后起。
比期年，朝．有黧黑之色。
是其故何也？君说之，故臣能之也。
昔越王勾践好士之勇教驯其臣私令人焚．．．．．．．．．．．．．．．．．舟失火试其士曰越国之宝尽在此．．．．．．．．．．．．．．！越王亲自鼓其士而进之，士闻鼓音，破碎（5）乱行，蹈火而．死者左右百人有余。
越王击金而退之。
④是故子墨子言曰：乃若夫少食恶衣，杀身而为名，此天下百姓之所皆难也。
若苟君说之，则众能为之。
况兼相爱、交相利，与此异矣！夫爱人者，人亦从而爱之；利人者，人亦从而利之；恶人者，人亦从而恶．之；害人者，人亦从而害之。
此何难之．有焉？特士不以为政，而士不以为行故也。
（取材于《墨子·兼爱》，有删节）[注]（1）“虽然”句谓：这样虽然好，但却是天下难以办到的事。
（2）牂(zāng)羊之裘：羊皮做的朴素衣服。
（3）要：通“腰”。
（4）胁息：屏气。

Williams was impressed with Benjamin and gave him two classic books on painting to take home. The books were long and dull.Benjamin could read only a little,having been a poor student.But he later said,＂Those two books were my companions by day,and under my pillow at night.＂While it is likely that he understood very little of the books,they were his introduction to classical paintings.The nine-year-old boy decided then that he would be an artist.1.What is the text mainly about?A.Benjamin’s visit to Philadelphia.B.Williams’influence on Benjamin.C.The beginning of Benjamin’s life as an artist.D.The friendship between Benjamin and Pennington.2.What does the underlined sentence in paragraph3suggest?A.The cat would be closely watched.B.The cat would get some medical care.C.Benjamin would leave his home shortly.D.Benjamin would have real brushes soon.3.What did Pennington do to help Benjamin develop his talent?A.He took him to see painting exhibitions.B.He provided him with painting materials.C.He sent him to a school in Philadelphia.D.He taught him how to make engravings.4.Williams’two books helped Benjamin to_____________.A.master the use of paintsB.appreciate landscape paintingsC.get to know other paintersD.make up his mind to be a painterBGetting less sleep has become a bad habit for most American kids.According to a new survey(调查)by the National Sleep Foundation,51%of kids aged10to18go to bed at10pm or later on school nights,even though they have to get up st year the Foundation reported that nearly60%of7-to12-year-olds said they felt tired during the day,and15%said they had fallen asleep at school.How much sleep you need depends a lot on your age.Babies need a lot of rest:most of them sleep about18hours a day!Adults need about eight hours.For most school-age children,ten hours is ideal(理想的).But the new National Sleep Foundation survey found that35%of10-to12-year-olds get only seven or eight hours.And guess what almost half of the surveyed kids said they do before bedtime?Watch TV.“More children are going to bed with TVs on,and there are more opportunities(机会)to stay awake,with more homework,the Internet and the phone,”says Dr.Mary Carskadon,a sleep researcher at Brown University Medical School.She says these activities at bedtime can zxxk get kids all excited and make it hard for them to calm down and sleep.Other experts say part of the problem is chemical.Changing levels of body chemicals called hormones not only make teenagers’bodies develop adult characteristics,but also make it hard for teenagers to fall asleep before11 pm.Because sleepiness is such a problem for teenagers,some school districts have decided to start high school classes later than they used to.Three years ago,schools in Edina,Minnesota, changed the start time from7:25am to8:30am.Students,parents and teachers are pleased with the results.5.What is the new National Sleep Foundation survey on?A.American kids’sleeping habits.B.Teenagers’sleep-related diseases.C.Activities to prevent sleeplessness.D.Learning problems and lack of sleep.6.How many hours of sleep do11-year-olds need every day?A.7hours.B.8hours.C.10hours.D.18hours.7.Why do teenagers go to sleep late according to Carskadon?A.They are affected by certain body chemicals.B.They tend to do things that excite them.C.They follow their parents’examples.D.They don’t need to go to school early.CFLORENCE,Italy—Svetlana Cojochru feels hurt.The Moldovan has lived here seven years as a caregiver to Italian kids and elderly,but in order to stay she’s had to prove her language skills by taking a test which requires her to write a postcard to an imaginary friend and answer a fictional job ad.Italy is the latest Western European country trying to control a growing immigrant(移民) population by demanding language skills in exchange for work permits,or in some cases, citizenship.Some immigrant advocates worry that as hard financial times make it more difficult for natives to keep jobs,such measures will become more a vehicle for intolerance than integration(融合).Others say it’s only natural that newcomers learn the language of their host nation,seeing it as a condition to ensure they can contribute to society.Other European countries laid down a similar requirement for immigrants,and some terms are even tougher.The governments argue that this will help foreigners better join the society and promote understanding across cultures.Italy,which has a much weaker tradition of immigration,has witnessed a sharp increase in immigration in recent years.In1990,immigrants numbered some1.14million out of Italy’s then 56.7million people,or about2percent.At the start of this year,foreigners living in Italy amounted to4.56million of a total population of60.6million,or7.5percent,with immigrants’children accounting for an ever larger percentage of births in Italy.Cojochru,the Moldovan caregiver,hoped obtaining permanent residence(居住权)would help her bring her two children to Italy;they live with her sister in Moldova,where salaries are among the lowest in Europe.She was skeptical that the language requirement would encourage integration.Italians always＂see me as a foreigner,＂an outsider,even though she’s stayed in the country for years and can speak the local language fluently,she said.8.Why does Cojochru have to take a language test?A.To continue to stay in Italy.B.To teach her children Italian.C.To find a better job in Italy.D.To better mix with the Italians.9.Some people worry that the new language requirement may____________.A.reduce Italy’s population quicklyB.cause conflicts among peopleC.lead to financial difficultiesD.put pressure on schools10.What do we know about Cojochru?A.She lives with her sister now in Italy.B.She enjoys learning the Italian language.C.She speaks Italian well enough for her job.D.She wishes to go back to her home country.二、七选五How to Do Man-on-the-Street InterviewsThe man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the spot.11.But with these tips,your first man-on-the-street interview experience can be easy.When your boss or professor sends you out to do man-on-the-street interviews for a story, think about the topic and develop a list of about ten general questions relating to it.For example,if your topic is about environmental problems in America,you might ask,“Why do you think environmental protection is important in America?”12.Hit the streets with confidence.13.Say,“Excuse me,I work for XYZ News,and I was wondering if you could share your opinion about this topic.”This is a quick way to get people to warm up to you.Move on to the next person if someone tells you she is not interested.Don’t get discouraged.14.Each interview that you get on the street shouldn’t be longer than ten minutes.As soon as you get the answer you need,move on to the next person.Make sure that as you go from interview to interview,you are getting a variety of answers.If everyone is giving you the same answer,you won’t be able to use it.A safe number of interviews to conduct is about six to ten.15.If your news station or school requires interviewees to sign release forms to appear on the air, don’t leave work without them.A.Limit your time.B.As you approach people,be polite.C.If you don’t own a camera,you can buy one.D.For new reporters,this can seem like a challenging task.E.To get good and useful results,ask them the same question.F.That number of interviews should give you all the answers you need.G.With a question like this,you will get more than a“Yes”or“No”reply.。

手惰市安逸阳光实验学校专题限时集训(二十) 阅读理解训练6 词义猜测题A(2016·乌鲁木齐诊断)I took a deep breath and walked through Mom's front door，my arms full of groceries.A challenge lay ahead of me：cooking the Easter Sunday feast.Me，someone who could barely boil water.What if I made everyone sick? It could truly be our family's last supper.Making the holiday meal was my brother's job，not mine.I could never fill his shoes.Peter had died in September at the age of 45 from a heart attack，but he'd been a natural in the kitchen all his life.He planned every course in detail，from the crescent rolls to the Dutch apple pie.My family was lost without him.We went out to dinner for Thanksgiving and ordered in pizza for Christmas.By the time Easter rolled around，though，I couldn't bear the idea of another holiday surrounded by takeout(外卖食品) boxes.Peter would have hated that.To him，there was nothing more important than a meal made with love.So I convinced Mom that we should cook Easter dinner together.Only，we were terrible cooks.What had I been thinking cooking for Easter dinner? I'd bitten off more than I could chew. No one could do this half as well as Peter.I stepped into the family room.Mom was still at church，but her newspaper was opened on the coffee table，to the sports section，as usual.She was a huge Notre Dame women's basketball fan，and the featured story was about forward Devereaux Peters，who was graduating.I read the headline and nearly dropped my grocery bags，Filling Peters' Shoes.That afternoon，cooking in the kitchen，I didn't feel so alone.Mom and I pulled together the Easter feast just fine.The ham may have been a little dry，but it was all made with love—just like Peter would have wanted.本文是一篇记叙文。

How to Be CreativeMost of us think that creativity is a quality belonging only to artists, writers, or dancers, rather than ourselves. 5 The following tips are a great beginning for developing our creativity.1. Get out of your comfort zoneWe eagerly accept the familiar and fear the unknown. Break out of your usual patternsand welcome creativity into your life. As stated earlier, the human brain was designed to recognize patterns. 6 In fact, our comfort zone is nothing more than a collection of patterns. As we become more efficient at recognizing and using patterns, we rely less on creativity to find new paths. We should force ourselves out of our comfort zones and open up new possibilities.2. Try different thingsIf you always do what you’ve always done, you’ll always get what you’ve always got. We are creatures of habits and routines, and creativity hates routines. If you usually drive to work, take the subway for a few days. 7 Interrupt your routine, experiment and try something new. New things are often creative, but the same old thing never is.3. 8Having a great idea is not enough, you must work to make it a reality. Have you ever seen a new product and realized that you thought of the same thing long ago? Yet someone else is making money with “your” idea. 9 The difference between a dreamer and a doer is action. Do whatever it takes to bring your ideas to life. If you can put them into practice, you are well on your way to improving your creativity in all areas of your life.A. Take actionB. Seek several optionsC. Thi nk from the other person’s point of view.D. If you normally eat in the office, have lunch under a tree.E. The truth is that we are all born with the capacity to be creative.F. We continue to create patterns and routines for almost everything we do.G. We all have great ideas sometimes, but only a few people turn their ideas into reality.二、语法填空（共20小题；每小题1.5分，满分30分）阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

高一英语下学期第六次限时练试题
中牟县第一高级中学2021-2021学年高一英语下学期第六次限时练试题第一卷第一局部：听力〔略〕第二局部：阅读理解〔一共两节，满分是40分〕第一节〔一共15小题；每一小题2分，满分是30分〕AWhen you eat out in a restaurant, it is not unusual to hear people yelling, “Let meget this one!〞 and sometimes see them pushing or arm wrestling(抢) to fight for the privilege(特权) of paying the bill.These fighters are often very loud and active. Each person involved shows an honest desire to pick up the bill, and in the end, all the people at the table givethe winner praise and gratitude.In fact, figuring out who will get the bill is always a headache for Chinese people at formal meals. Although the people hosting the meal are very likely to pay the check,it is a common practice to make a token(装样子的) effort to pay the bill, but you will embarrass them if you do end up actually chipping in some cash(凑钱).In recent years, going Dutch (AA 制) has been embraced by many young people. But older generations who fear “losing face〞 still find it embarrassing and stingy (小气的) to calculate each person’s share of the bill. As travel guide brand Lonely Planetnoted, it is considered “the height of unsophistication (不懂人情世故)〞.But these days, thanks to digital payment apps, splitting the bill electronicallyis becoming a widely-accepted idea. Even people from older generations may be temptedto do so.By scanning a QR code and paying the share via social networking tool WeChat and e-commerce app Alipay on their smartphones in one easy click, urban Chinese are finding it easier to save them the embarrassment of figuring out each person’s payment when they order a meal.This function “has made going Dutch less hassle (费事) and more fun in China〞, CNN noted.“Because of their convenience, many of us are never without our phones.〞 And person-to-person mobile payment services are incredibly easy to use and savethetrouble of dealing with change,〞 said 18-year-old student in China. “You can also leave funny notes using emoji (表情符号) like a bowl of rice or a cup of tea to describea meal that you have shared.〞21.What is the article mainly about?A.The Chinese tradition of dining out with friends.B.A new trend of splitting the bill in China.C.How social networking tools have influenced our daily lives.D.Why people in China argue over who pays the bill when dining out.22.Many Chinese people make a token effort to pay the bill because________.A.They don’t want to be considered unsophisticatedB.They want praise and gratitude from their friendsC.They consider it an honor to host the meal and pay the billD.They find it hard to work out how much each person needs to pay23.According to the article, what are the advantages of using digital payment apps tosplit the bill?a.T hey’re easier to use and more interesting.b.T hey save the trouble of dealing with change.c.T hey make it easier to figure out how much money each person had to pay.d.T hey make people less embarrassed to split the bill.A. a, bB. b. cC. a, b, dD. b, c, dBHave you ever made your life look a little more charming than it actually is by posting truths on social media? If so, you may be damaging your mental health.The posts we make on social media platforms allow us to look back and see what we did on a given day. But what happens when, in an effort to(企图) impress our online friends, photos and videos we post become beautified versions of the things we did?A young girl named Sophia went out to a romantic anniversary dinner with her boyfriend, had a near relationship-ending fight during dessert, then came home and posted, “Had the best time out with the love of my life!〞— even with a photo ofthe meal. No surprise, but according to a new study, Sophia was by no means unique. Two- thirds of users admit lying about their lives on social media with 20 percentof young people between the ages of 18 and 24 stating that they edit their own storiesby frequently lying about relationships and promotions(升职).By beautifying our online stories, we are harming our memories. We start believing the stories we tell rather than remembering what really happened. Soon, the real experience is lost and all that remains is the beautified version of history.Scientists fear that these edited stories will end up changing our memories.It’swell confirmed through research that our own memories are often unreliable and canbe easily controlled. Writing down one’s life in the form of a journal, or even on social media can help us keep our memories undamaged, but only if we tell the truth.So recording our experiences through whatever medium, to later recall lessons we learned, is not only acceptable but desirable. In fact, looking back at our own past- however embarrassing or uncomfortable - is not just healthy but can be enjoyable.24.Why did Sophia post her story with a photo of the meal?A.To make her post attractive.B.To show his photography skill.C.To convince others of her story.D.To show how enjoyable the meal was.25.In what kind of tone did the writer write the text?A. Encouraging.B. Critical.C. Humorous.D. Enthusiastic.26.The last paragraph implies that many people don’t realize ________.A.recalling the unpleasant past can also be enjoyableB.writing down our life on social media does no good to usC.recording experiences through media is unacceptableD.recording our experiences through media is beneficial27.What a lesson can be drawn from the text?A.Leaving others a good impression is desirable.B.Editing our online stories weakens our memory.C.Posting our experiences on social media is risky.D.Beautifying our history ends up hurting ourselves.CThe world's richest man might seem to have it all, but Bill Gates has one regret. The self-made billionaire said he felt stupid for not knowing any foreign languages. Speaking in his third Ask Me Anything question-and-answer session for online forum Reddit(红迪网), the Microsoft founder said that he wished he spoke French, Arabicor Chinese.He said, "I took Latin and Greek in high school and got As and I guess it helpsmy vocabulary. I keep hoping to get time to study one of these—probably French becauseit is the easiest. I did Duolingo for a while but didn't keep it up."Gates, who is worth $79.3 billion, praised Facebook founder Mark Zuckerberg for surprising an audience in Beijing when he spoke fluent Chinese. "Mark Zuckerberg amazingly learned Chinese and did a Q & A with Chinese students—unbelievable, isn't it?" he said.This isn't the first time for Gates to admit his regret over language. He also showed his habits at home and personal insights.Last February, Gates said he likes to do the dishes himself—to his own special standards every night and also told the interviewer that his wife, Melinda, would likely want Samuel L. Jackson to play her husband in a biopic(传记片).He also admittedthathe would pick up a $100 bill if he found it on the street.As he took the top spot on Forbes(福布斯) 28th Annual Billionaires list last year for the fourth time, he said he is pretty basic when it comes to spending on clothesand food, but that he enjoys investing in shoes and rackets(球拍) when he plays tennis.When asked a life lesson he had to learn the hard way, the billionaire said staying up too late is a habit he is still trying to break. "Don't stay up too late even ifthe book is really exciting. You will regret it in the morning. Pam is still workingon this problem," he said.28.Which of the following can be the best title for the passage?A. An Interview with Bill GatesB. How Bill Gates SucceededC. Bill Gates' RegretD. The Richest Billionaire29.The underlined part in paragraph 8 may actually mean that _______.A.it is important to lay a good foundation of lifeB.food and clothing are basic needs for people's lifeC.he never cares about buying food and clothingD.he doesn't spend much money on food and clothes30.What advice did Bill Gates give?A.Do the dishes yourself at home.B.Be a good language learner.C.Avoid staying up too late.D.Pick up the $100 bills in the streets.31.Which of the following is true according to the passage?A.Bill Gates is also the founder of Facebook.B.Bill Gates was good at learning languages in high school.C.Bill Gates topped the list of Forbes 28 times.D.Bill Gates' wife wants Samuel to play a game with Gates.DBelieve it or not, we all have an inner-child living inside of us. One of the greatest problems is people’s desire to silence the inner-child. Instead, welcomingthis voice to the conversation can be very beneficial and help you in many areas of your life.Why is it so important to listen to your inner child?Do you remember you wanted to be an adult more than anything else when youwere young? But now y ou’re an adult, and do you ever find y ourself thinking, “I wish I were a kid again?〞That’s where your inner-child comes in. That’s the voice inside of you telling you to have fun, be silly and let loose. Adult life is fullof important responsibilities, but once in a while you just have to let go and havefun like a child. It’s healthy and good for the soul to not take things so seriouslyall the time.We can tell bad choices and mistakes of the past, but unless you help your inner- child heal and recover, planning for the future will always be difficult. Theinner-child will relive these painful experiences until you learn to accept them, forgive and let go. We must show love and acceptance to our inner-child, as this isthe only way to heal, move on and not continue to suffer from the pain of these unpleasant times. This is the opportunity to go back in time and let you know justhow wonderful, beautiful and special you truly are.One of the most common times your inner-child is likely to appear is when y ou’re facing a decision you are unsure about. Naturally, when we were children, doubt and uncertainty scared many of us. So, it’s no surprise that when faced with these momentsas adults, the inner-child decides to show up. Don’t let this scare you; instead,listen to that voice as it is trying to guide you in the decision-making process. Ask it questions, speak with it.When you can start to see your inner-child as your partner who helps guide you through this crazy life, it’s amazing what can happen. Don’t fight it. Go with it and see how it changes your life for the better.32.What do people usually do to the inner-child?A. Stop it.B. Welcome it.C. Rescue it.D. Blame it.is it always hard to plan for the future?A. We have no fun in our life.B. We always make bad choices.C. We don’t help inner-child recover.D. We always experience unhappy times.34.When will inner-child probably come up?A. When we make decisions.B. When we enjoy ourselves.C. When we make mistakes.D. When we feel unpleasant.35.What may happen if we accept inner-child?A. We may feel more painful.B. We will make more mistakes.C. We will take things more seriously.D. We may have a better life.第二节〔一共5小题；每一小题2分，满分是10分〕根据短文内容，从短文后的选项里面选出能填入空白处的最正确选项。
