《凉州词》（王昌龄）《现代文阅读：南州六月荔枝丹荔枝大小，通常是直径三四厘米，重十余克到二十余克。
20世纪60年代，广东调查所得，有鹅蛋荔和丁香大荔,重达四五十克。
还有四川合江产的“楠木叶”，四川果树良种图谱》说它重19克左右，《中国果树培学》则说大者重60克，不知哪一本书记载正确。
所谓膜如紫绡，是指壳内的一层通常白色而紧贴壳的内壁的薄膜。
说它“如紫绡”，是把壳内壁的花纹误作膜的花纹了。
明代徐渤有一首《咏荔枝膜》诗，描写吃荔枝时把壳和膜丢落在地上，好似“盈盈荷瓣风前落，片片桃花雨后娇”，是夸张的说法。
荔枝的肉大多数白色半透明，所以说它“莹白如冰雪”。
有的则微带黄色。
从植物学的观点看，它不是果肉，而是种子外面的一层膜发育而成的，特称假种皮。
真正的果肉倒是前面说的连同果壳丢弃的那一层膜。
荔枝肉的细胞壁特别薄，所以入口一般都不留渣滓。
味甜微酸，适宜生食。
有的纯甜。
早熟品种则酸味较强。
荔枝晒干或烘干，肉就成红褐色，完全失去洁白的面貌。
荔枝不耐贮藏,正如白居易说的:“一日而色变,二日而香变,三日而味变,四五日外,色香味尽去矣。
”在21摄氏度的环境里，可贮藏一二星期。
人们一直在设法延长贮藏期，以利于长途运输。
早在1800多年前，即东汉和帝时，唐羌曾谏阻从南方向洛阳贡献生荔枝和龙眼。
唐代杜牧诗云：“长安回望绣成堆，山顶千门次第开。
一骑红尘妃子笑，无人知是荔枝来。
”当时是“昼夜奔腾，有毒虫猛兽之害”（宋蔡襄），“颠坑仆谷相枕藉”，“惊尘溅血流千载”（宋苏轼）。
为了封建统治者个人口腹之好，竟如此劳民伤财！但也足见当时荔枝贮藏与运输的不易。
荔枝的核就是种子，长圆形，表面光滑而色棕褐，少数品种为绿色。
优良的荔枝，种子发育不全，形状很小，有似丁香，也叫焦核。
现在海南岛有无核荔枝，核就更加退化了。
（选自贾祖璋《南州六月荔枝丹》）30.节选部分的说明顺序是（）A.由远及近B.由表及里C.由实及虚D.由虚及实31.下列对荔枝的特征描述不正确的一项是（）A.荔枝的大小一般在二十克左右，如果达到四十克以上，就称得上“大荔”了。
B.白居易在《荔枝图序》中说“莹白如冰雪”的荔肉是荔枝的假种皮，并非荔肉。
真正的荔肉其实早在食用之前，就被人扔掉了。
C.荔枝不耐贮藏，所以古代君主若是想吃荔枝，须用快马飞骑日夜传递。
D.优良的荔枝，种子发育不全，形状很小，因而不能种植。
32.文中引用诗词典故，下列对其作用表述正确的一项是（）A.作者引用明代徐勃的一首《咏荔枝膜》，是为了进一步印证白居易所言“膜如此绡”的正确性。
B.作者引用杜牧的《过华清宫绝句》，既从侧面写出了荔枝不耐贮藏的特点，又含有凭吊古代和讽刺唐代统治者的意味。
C.作者多次引用白居易的《荔枝图序》，既有助于说明荔枝的有关特征，又增强了说明的生动性和艺术性。
D.作者引用《四川果树良种图谱》和《中国果树栽培学》中有关荔枝大小的内容，意在表明自己博学多识，是有关荔枝种植方面的专家。
英语部分：Passage1Let us all raise a glass to AlphaGo and the advance ofartificial intelligence.AlphaGo,DeepMind’s Go-playing AI,just defeated the best Go-playing human,Lee Sedol.But as wedrink to its success,we should also begin trying to understandwhat it means for the future.The number of possible moves in a game of Go is so huge that,in order to win against a player like Lee,AlphaGo was designed to adopt a human-like style of gameplay by using a relatively recent development—deep learning.Deep learning uses large data sets,“machine learning”algorithms(计算程序)and deep neural(神经的)networks to teach the AI how to perform a particular set of tasks.Rather than programming complex Go rules and strategies into AlphaGo,DeepMind designers taught AlphaGo to play the game by feeding it data based on typical Go moves.Then, AlphaGo played against itself,tirelessly learning from its own mistakes and improving its gameplay over time.The results speak for themselves.Deep learning represents a shift in the relationship humans have with their technological creations.It results in AI that displays surprising and unpredictable menting after his first loss,Lee described being shocked by an unconventional move he claimed no human would ever have made.Demis Hassabis, one of DeepMind’s founders,echoed this comment,“We’re very pleased that AlphaGo played some quite surprising and beautiful moves.”Unpredictability and surprises are—or can be—a good thing.They can indicate that a system is working well,perhaps better than the humans that came before it.Such is the case with AlphaGo.However,unpredictability also indicates aloss of human control.That Hassabis is surprised at his creation’s behaviour suggestsa lack of control in the design.And though some loss of control might be fine in the context of a game such as Go,it raises urgent questions elsewhere.How much and what kind of control should we give up to AI machines?Howshould we design appropriate human control into AI that requires us to give up someof that very control?Is there some AI that we should just not develop if it means any loss of human control?How much of a say should corporations,governments,experts or citizens have in these matters?These important questions,and many others like them,have emerged in response,but remain unanswered.They require human,not human-like,solutions.So as we drink to the milestone in AI,let’s also drink to the understanding thatthe time to answer deeply human questions about deep learning and AI is now.33.What contributes most to the unconventional move ofAlphaGo in the game?A.The capability of self-improvement.B.The constant input of large data sets.C.The installation of deep neutral networks.D.The knowledge of Go rules and strategies.34.Apotential danger ofAI is________.A.the loss of human control C.the fierce competitionB.the friendly relationship D.the lack of challenge35.How should we deal with the unpredictability ofAI?A.We should stopAI machines from developing even further.B.We should call on the government to solve these problems for us.C.We should rely on ourselves and come up with effective solutions.D.We should invent even more intelligent machines to solve everything.36.What’s the author’s attitude towards this remarkable advance in AI?A.Supportive.B.Optimistic.C.Doubtful.D.Cautious.Passage2Why Doesn’tAnybody CopyApple?Apple’s products are the envy of the world.They have been spectacularly successful and are widely imitated,if not copied.The minute Apple crystallizes aproduct,everyone knows how to compete.This idea that the basis of competition isset by Apple and then the race is on to climb the path of improvement is unquestionable.When Apple releases a product that defines a category or dramatically changes the structure of an industry,it becomes obvious what needs to be built.Butwhat I wonder is why everyone wants to copy Apple’s products but nobody wants to copy being Apple?I can think of two reasons.Firstly,Apple is not worth copying because it’s not successful;secondly,Apple’s success cannot be copied because it is a magical process.There is a great deal of evidence for the first hypothesis.The idea of Apple being successful is not something reflected in its stock price.Being valued lower than the average company in the S&P(标准普尔)500indicates that to whatever degree Apple was successful in the past,it’s not seen by the vast majority of observers as successfulin the future.Why should one bother copying Apple if it results in being punishedwith a low valuation?If one works really hard at innovation and then that innovation becomes commoditized(商品化)very quickly,why should one bother?When innovation practitioners are asked what makes Apple successful,the answers regarding the cause of this success border on the mythical.The climax of this hypothesis is the“chief-sorcerer”theory of success which places one magician,like Steve Jobs,in charge of casting all the right spells(符咒).What about Apple’s own opinion of what makes it tick?Tim Cook refers to agreat team and integration of hardware,software and services as unique Apple advantages.It’s a better explanation.Integration is something that can take a long time,but it is possible with great effort.A few companies are starting to make movesin that direction,but efforts are half-hearted.There is no“move the Earth”panic to become an integrated company from Samsung,Google or Microsoft.My own suspicion is that Apple is more aware of what makes it special than itlets out.However,as Tim points out,it’s not a formula.It’s complex,it’s subtle,butit’s not magic.It’s a process that requires a degree of faith and courage.37.When a new product ofApple comes out,often it____.A.ruins an industry dramaticallyB.starts a revolution of an industryC.puts itself in an unbeatable positionD.is soon overtaken by imitated products38.According to the passage,other companies don’t“copy being Apple”because____.A.Apple is not a successful companyB.they have no access to relevant resourcesC.it’s hard to find a magician like Steve JobsD.being Apple takes more than time and efforts39.We can infer from Para.5that____.A.other companies are dedicated to integrationB.Apple itself is fully aware of its unique advantagesC.Apple will hold the leading position in this industryD.other companies don’t have a great team as Apple does40.What does the author think of Tim Cook’s statement?A.Convincing. C.Unquestionable.B.Disappointing.D.Acceptable.科学部分：41.太平洋正在如何变化（）A、变小B、变大C、不变D、有时变小有时变大42.经线和纬线之间的夹角是（）A、60°B、90°C、45°D、30°43.下列有关潮汐的说法正确的是（）A、地球站在太阳和月球连线上时，会发生小潮B、月球站在太阳和地球连线上时，会发生小潮C、每天每个地方一定会有两次高潮和两次低潮D、太阳、地球和月球成直角时，会发生小潮44.如果地球只有一个苹果那么大，那么大气的厚度相当于（）A、果皮B、果肉C、果核D、果皮上的水汽45.以下哪个不是液体表面张力造成的现象？（）A、船漂在水面上B、树叶上的水滴C、小虫在水面上行走D、针漂在水面上46.以下哪个是玻璃不可能具备的特点？（）A、耐加热B、熔化后可以吹成不同的形状C、比沙子熔点低D、结晶体47.水分在人体内最重要的角色是以下哪一个？（）A、容器B、反应物C、溶剂D、催化剂48.如果你受伤了，以下哪种血液组分会帮助你止血？（）A、红细胞B、白细胞C、血小板D、血浆49.保温瓶的双层玻璃夹层里被抽成真空加以密封。
