D.To evaluate musicals.ⅡMost people find sugar hard to resist. Our big brains need lots of energy and sugary foods provide plenty of it. But when calories are too readily available, it is easy to overdo it.There has been no shortage of research on sugar substitutes that trigger a sweet sensation without the calories, but these alternatives also taste slightly bitter for many people. W hat’s more, evidence from animal and human studies has linked some to glucose intolerance and weight gain.One promising alternative is found in the fruit of Synsepalum dulcificum (奇妙果), a plant native to West Africa. These miracle berries don’t taste suga ry themselves, but if you try something sour afterward, it will taste miraculously sweet. In Benin, the fruit is eaten fresh and is mostly used as a sweetener to have with sour foods and drinks. The berry is appreciated by local consumers, especially the kids and people with diabetes who use it as a substitute for synthetic sugar.The chemical, a protein named miraculin, was identified in 1968 and a team in Japan discovered how it works in 2011. At neutral pH, miraculin is an antagonist to our sweet taste receptors, meaning it blocks the taste of sweetness. But in the presence of an acid, miraculin changes shape and is able to activate the receptors.Despite the miracle berry’s promise as a sugar substitute, it is only produced on a smallish scale and isn’t available worldwide. The berries don’t travel well and the plant is slow to grow and mature.To create an alternative source of miraculin, researchers in Japan have genetically engineeredtomatoes to produce the protein, while another team is working on increasing the production of miracle berries in West Africa. Earlier 202X, a team in China published the genome of Synsepalum dulcificum. A Spanish start-up plans to promote sustainable cultivation of the plant in Ghana and market the dried berries as a food supplement.;4.What is special about Synsepalum dulcificum as a sugar alternative?A.It contains many calories itself. B.It makes sour food taste sweet.C.It will gain weight and cause disease. D.It does good to kids and diabetic patients.;5.How do the miracle berries work on sour food?A.By changing the pH of a food. B.By increasing its sugar content.C.By producing shape-variable miraculin. D.By weakening the sweet taste receptors.;6.What does the underlined word “antagonist” probably mean in Paragraph 4?A.Enemy. B.Assistant. C.Factor. D.Receiver.;7.Why are the miracle berries hard to get?A.They are only locally available. B.They cannot be grown elsewhere.C.It is expensive to transport them. D.It takes long to harvest a small amount.二、七选五阅读How to make a successful apology. Have you done something that you feel bad about? Is there a person who you have treated badly? Do you need to say “I’m sorry” to someone? Here are five things you can do to have a successful apology.● Make your apology real. 8 People can tell if you take responsibility for what you did or if you are lying.● Do not make excuses. 9 It is saying that you were wrong to do it.● 10 An apology should show that you have learned from what you did. Show that you mean what you say.● Make it clear that you are apologizing. Just saying “I’m sorry” is not enough. Talk about what you did and then say that yo u feel bad about doing it. 11● Be prepared for the unexpected. Be prepared for it to take some time for you r apology to be accepted. This may be a long moment, a few minutes, or even days or weeks. The person may stay angry with you. 12A.Be patient and hopeful.B.Make a promise to change.C.Choose the right time to apologize.D.An apology will be better accepted if it is sincere.E.An apology is not explaining why you did something.F.You can give your apology to the other person as a letter.G.It is important that the person knows you are apologizing.三、语法填空阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确情势。

1、阅读下面的文字,完成下列小题。
材料一:中国政府控制着中国三大移动运营商,并一直在指导它们在北京、上海等城市部署大规模 5G 测试网络。
投资分析师克里斯莱恩表示:“中国运营商将自己的工作视为执行政府政策,而大多数全球电信公司试图平衡竞争因素,因此自然会放慢投资步伐。
” 中国政府还承诺向中国运营商提供大量 5G 频谱。
与美国和许多其它国家的运营商相比,这种安排要宽松得多,在这些国家,运营商向监管机构支付数十亿美元,以获得使用频谱碎片的权利。
为中国移动运营商建设基础设施的中国塔公司表示,在政府分配频谱后的 3 年内,该公司将有望实现 5G 覆盖中国。
在美国,这一进程可能会慢得多,因为需要建设更多基础设施。
诺基亚全球 5G 技术开发主管迈克墨菲表示,中国运营商将主要使用与 3G 和 4G类似的频段,这将使它们能够重用一些现有的基站。
但在美国,美国电话电报公司和威瑞森计划使用一种高频频段,这种频段的信号传输距离较短,所需的基站数量是 4G 的 3 至 4倍。
运营商需要与每个城市就安装这些站点的合同进行谈判,一些城市已经发出了抵制的信号。
(摘编自《中国为何在 5G 领域遥遥领先》)材料二:5G 的“领跑”优势,来之不易,凝聚着中国企业坚持科技创新所付出的艰辛和汗水。
以中兴通讯为例,2013 年至 2017 年,中兴通讯研发投入达 23.18 亿元人民币,占营业收入比例约 12。
2018 年 1-9 月,研发投入为 85.26 亿元人民币,占营业收入比例为 14.5。
专利数字更为直观。
截至 2018 年 6 月 30 日,中兴通讯专利累计超过7.3万件,全球授权专利累计超过 3.5 万件,其中 5G 专利申请超过 3000 件。

1、阅读下面的文字,完成下面小题。
所谓“元典精神”,是指一个民族的“文化元典”所集中体现的原创性精神。
这种典籍因其首创性及覆盖面的广阔性、思考的深邃性,而在该民族的历史进程中成为生活的指针。
印度的《华陀经》、波斯的《古圣经》,柏拉图、亚里斯多德等先哲的论著,犹太及基督教的《圣经》、伊斯兰教的《可兰经》,都被相关民族视为“圣典”或“元典”。
在中华文化系统中,堪称元典的是“六经”,与之相关的《论语》《孟子》《老子》等典籍也具有“元典”性质。
文化元典是特定时代、特定地域的产物,当以历史文献视之,“六经皆史”即此之谓也。
同时,元典的某些基本精神又能观照久远的岁月,反复被后人重新刻勒,对该民族的价值取向、行为方式、审美情趣、思维定式造成深远而又长期的影响。
元典的这种超越性并非某种神秘因子所造成,乃是由其基本特质所致:它们的思考指向宇宙、社会和人生的普遍性问题,而这些问题是各个时代的人类所始终关心的,也就是说,元典讨论的是不朽的主题,同时,元典在回答这些始终困扰着人类的普遍性问题时,提供的是一种哲理式的框架,而并非实证性的结论;是一种开放式的原型,而并非封闭式的教条,这使元典不致因内容和形式的时代局限沦为明日黄花,而以一种灵感的清泉,赢得不朽性,一再发挥巨大的启迪功能。
从文化史角度审视,近代文明既是对中世纪文明的继承和发展,同时也是对中世纪某些束缚社会进步的制度和精神的否定。
近代文明实现这种对中世纪的否定,往往借助于对古代文明某些因素的“复归”。
当然,这种复归并非复古,而是一种螺旋式上升的进程。

1、阅读下面的文字,完成下面小题。
驮马施蛰存我第一次看见驮马队是在贵州,但熟悉驮马的生活则在云南。
那据说是所谓“果下马”的矮小的马,成为一长行列地逶迤于山谷里,就是西南诸省在公路出现以前唯一的交通和运输工具了。
当我乘着汽车,从贵州公路上行过,第一次看见这些驮马队在一个山谷里行进的时候,我想,公路网的完成,将使这古老的运输队不久就消灭了罢。
但是,在抗战三年后的今日,因为液体燃料供应不足,这古老的运输工具还得建立它的最后功业,这是料想不到的。
西北有二万匹骆驼,西南有十万匹驮马,我们试设想,我们的抗战乃是用这样古旧的牲口运输法去抵抗人家的飞机汽车快艇,然而还能支持到今日的局面,这场面能说不是伟大的吗?因此,当我们看见一队驮马,负着他们的重荷,在一个峻坡上翻过山岭去的时候,不能不沉默地有所感动了。
一队驮马,通常是八匹十匹或十二匹。
每一队的第一匹马,是一个领袖。
它是比较高大的一匹。
它额上有一个特别的装饰,常常是一面反射阳光的小圆镜子和一丛红绿色的流苏,项颈下挂着一串大马铃。
当它昂然地在前面带路的时候,铃声咚咙咚咙地响着,头上的流苏跟着它的头部一起一落地耸动着,后边的马便跟着它行进了。
或是看着它头顶上的标帜,或是听着它的铃声,因为后面的马队中,常常混杂着聋的或盲的。
倘若马数多了,则走在太后面的马就不容易望到它们的领袖。
你知道,驮马的行进,差不多永远是排列着单行的。
管理马队的人叫做马哥头,他常常管理着四五个小队的驮马。
这所谓管理,实在不很费事。
他老是抽着一根烟杆,在马队旁边,或前或后地行进着。

一、现代文阅读 (36分)(一)论述类文本阅读(本题共3小题,9分)阅读下面的文字,完成1~3题。
张彦远《历代名画记》成书于九世纪中期,是中国历史上第一部绘画通史著作,集画史、画论、画家小传于一体,具有里程碑式的意义。
张彦远收集整理晚唐之前的画论史传,别出机杼,分章别类,考察绘画相关的诸多问题,为中国绘画史写作立下规范。
《历代名画记》共有十卷,前三卷为品学专论文章,后七卷皆为画家小传,记载许多画家的生平及其评价。
张彦远的画学成就及原因可以作如下的概括:“ (张彦远)高祖以下入则为相,出则历典名郡,搜藏历代书画极富,因战乱丧失殆尽。
至彦远时,虽所余无几,但因其精于鉴赏,烂熟历代文献典故,故能成此规模空前、亦史亦论的画学专著。
”正因为张彦远的家学渊源和个人学养,促成了这部史论俱佳的画学专著。
到目前为止,《历代名画记》的研究成果主要集中在整理校注和绘画思想研究上,大都未涉及其中蕴含的文学价值。
《历代名画记》的文学价值可分为三个部分:第一,《历代名画记》卷四至卷十的画家小传中,许多画家兼及诗人的身份。
尽管唐之前画家小传多采自前人所著画传史书,但唐代画家小传多出张彦远自己之手,对唐代具备绘画才能的诗人生平考订多有裨益,有些文本和逸事甚至仅存于《历代名画记》中。
且由于张彦远出自“三相张家”,门第崇高,见闻既广,又熟诗文,众多文学史料赖其保存。
故张彦远《历代名画记》中的画家小传有助于唐代绘画诗人生平的考订,载录的诗文有助于文学史料的保存,更可以通过画家小传的记载考察唐代绘画、文人和唐代社会的互动关系。

城上青山如屋里,东家流水入西邻。
闭户著书多岁月,种松皆作老龙鳞。
(注)①新昌里:在长安城内。
吕逸人即吕姓隐士。
②凡鸟:据《世说新语·简傲》记载,三国魏时的嵇康和吕安是莫逆之交,一次.吕安访稀康未遇,康兄嵇喜出迎,吕安于门上题“风”字而去,嘲讽稀喜是“凡鸟”。
③看竹:事见《晋书·王羲之传》。
王羲之之子王徽之闻吴中某家有好竹,坐车直登其门观竹,“讽啸良久”。
1.下列对这首诗的赏析,不正确的一项是A.首联借《桃花源记》中的世外桃源比况吕逸人的住处,写吕逸人不染风尘的超俗节操。

I’ll tell you why, after a bit of 11 .I spent my first 20 years in the mountains of the Carolinas, one of the places God 12 when he looked at his creation and said, “Oh my.”For the next three decades, I lived on the 13 of Califo rnia, another “oh my” kind of place, in a house near the beach with three headstrong children and their basketball 14 father.Then the children 15 up to be headstrong adults, and we lost the coach to cancer. SoI spent some years 16 in m y “family museum” with four bedrooms, five sets of dishes, a17 basketball court and a whole lot of great memories. During those years, to my 18 , I discovered that “alone” can also be an “oh my” kind of place. With an abundance of blessings, I was humbled, grateful and happy. I had no need, no plans to 19 it.My life went on 20 until one day, I met a good man who makes me laugh and slow down to watch sunsets—I’m living a new 21 of my life. I fell in love again. I remarried and moved with my new husband to the 22 place on Earth I ever dreamed I’d call home: the desert outside Las Vegas. Perhaps you’re wondering what sort of woman grows up in the Bible Belt, raises her children in Paradise, and 23 on the outskirts of Sin City?That would be me, a woman who has tried, no matter what happened, to 24 her heart wherever it may lead. Growing up, if I was 25 , my grandma would say: “Honey, follow your heart. It’s a good heart. Trust it.”I had no idea what she meant, not 26 today. But in Sunday school, I learned that the heart is a container for love—the love of God, the love of family and friends, the love of all that we hold dear—and that it speaks to us with the voice of love, always in a whisper.27 , I learned to listen for that whisper. It’s hard to hear it sometimes over other voices—logic, anger, envy, jealousy, insecurity and such. They don’t whisper. They 28 . But listen closely. You can spot it.So why do I feel lucky? Here I am in a n “oh my” kind of place on an “oh my” kind of day. I followed my heart from the mountains to the coast to the desert. I miss family and friends and mountains and beaches and 29 , especially fall. But I visit them often, if only in mind.Yesterday is 30 . Tomorrow’s a dream. All we have is this one, sweet, lovely “here and now.” Here’s wishing for all of us an “oh my” kind of life.11.A. thought B. music C. wine D. background12.A. argued B. meant C. ignored D. stressed13.A. coast B. farm C. river D. hill14.A. playing B. watching C. judging D. coaching15.A. stood B. lived C. grew D. rose16.A. alone B. alive C. away D. apart17.A. huge B. small C. silent D. noisy18.A. regret B. surprise C. disappointment D. satisfaction19.A. accept B. change C. face D. avoid20.A. quietly B. rapidly C. naturally D. slowly21.A. page B. chapter C. level D. stage22.A. last B. first C. best D. worst23.A. steps up B. joins up C. comes up D. ends up24.A. melt B. follow C. read D. open25.A. at ease B. at a loss C. in panic D. in trouble26.A. before B. till C. even D. only27.A.

If a driver makes any of these offences, the points will be recorded. When the driver gets a certain number of points, he will be forbidden to drive for a certain amount of time.What are the purposes of this system?This is a system designed to make road much safer. It can improve standards of driving and reduce the accident rates.Which traffic offences will result in Driving Offence points?Of course, not all traffic offences are covered by this system. Only those that have directIf you have got 10 points or above, but still less than 15 points, you will receive a warning letter from the Transport Department. This letter will tell your recode of driving Offence Points and remind you of the result of getting more points. It is hoped that this warning will change your driving behavior for the better.What will happen if you have got 15 points?If you have got 15 points or more within two years, a court will take away your driving license. The first time you are found guilty you will not be able to drive for three months, but if you are caught a second time you will not be able to drive for six months.31.

You will have to give up driving for 3 months.D. You will be defined as guilty. 四.任务型阅读Few people need to be told not to overspend on credit or debit cards or to curb impulse shopping. You know you shouldn’t, even if you always do. What you need are solutions. Whatever your problems with money, you can change—but it’s going to take work. After all, you’re trying to break lifelong patterns. Start with these strategies.Strategy 1A lot of people set themselves up for failure because they have a mindset of either indulgence (放纵) or deprivation (克制). If you try to deprive yourself of too much, where you spend almost nothing, then you end up giving up, and you indulge, and then you overspend. So if you have an unrealistic plan, you’re probably going to lose control. Good habits happen when planned; bad habits happen on their own.Strategy 2Changing your mindset is effective in solving the problem. Take Smith-Acuna for example. She says she had a couple in therapy who constantly quarreled about what she feels has become a monetary cliché. They would always argue about how much money they were spending at Starbucks. The wife loved capping off each workday with a drink. Ultimately, the wife ended up quitting her Starbucks habit. Instead of replacing her drink with nothing, she got something else, something free, in return.Strategy 3It’s a good start if you switch from paying for merchandise and services with a debit or credit card to paying with cash. It’s easy when you’re using plastic to mindlessly swipe and fall into a pattern o f not thinking or noticing how much you’re actually spending. You can divide up your money and put it into envelopes, marking down on the envelopes what each pile of money is for. That can make it easier to see where your money is going.Strategy 4Get a receipt for every purchase. Breaking up your expenses into categories like food, clothing, housing, medical care and so on, but also labeling each expense as a need or a want. Be realistic as to what is really necessary. A need is something where you would die or go to jail if you didn’t spend the money or ruin your credit. At the end of the month, total up all the categories.Do this, and you’ll be more educated about how much money you actually have, and how much you have left over for fun stuff.Strategy 5There is probably a reason you developed bad habits, which are often adopted on the road easier traveled. So if you’re suddenly balancing your bank account every day, or you’re regularly putting money into an emergency fund, plan to give yourself some sort of prize for the past two五.书面表达请根据你对以下两幅图的理解,以“Being a civilized passenger on the bus”为题,用英语写一篇作文。
