My mother died in August 2005.Eight months later,I began to come out of the fog of sadness and depression to find a new purpose for my life.

Like many of my generation,I had lived only for myself —traveling,acquiring possessions,rising to a position of importance and seeking financial rewards.I was“charitable”and“volunteered”for various causes,but really didn’t give of myself.

In the spring after my mom’s death,I found myself waking in the middle of the night with one thought.I felt forced to offer myself as a living kidney donor.My husband Robb had received the gift of life through a kidney transplant(移植)from a dead donor in 1999,so I was familiar with the enormous need for donors and knew several people who were waiting for a lifesaving transplant.I decided to offer myself to be matched with the most compatible(互不排斥的)person on the waiting list at my local transplant center.

I was paired with 71-year-old Dee from New Jerse who had survived for six years on peritoneal dialysis(腹腔透析).At her 70th birthday,her family threw a big party as they did not expect her to live much longer.Dee has become my very good friend.Almost two years after the transplant,I was privileged to celebrate her 50th wedding anniversary with her husband,their five children and their extended family.

In donating my kidney,I extended myself in a way far beyond what I ever believed was possible.I did so in honor of my mother who sacrificed so much for me and my sisters,and in memory of my husband’s donor who extended her 1ife through him.

I encourage all who enjoy the gift of good health to share with others,either as a living donor or by appointing organ donation upon death.By extending yourself through organ donation,you will live on through others in an extraordinary way and give comfort to your loved ones.

25.What does the underlined phrase“give of”mean?

A.Relieve.B.Devote.C.Appreciate.D.Forgive.

26.What can we infer from Paragraph 4?

A.Dee was the author’s old friend.

B.The author attended Dee’s birthday party.

C.Dee treated the author as a family member.

D.The author’s donation made Dee live six years longer.

27.What would be the best title for this text?

A.An old lady benefited from organ donation

B.The memory of my beloved mother

C.The deep meaning of love

D.Extend yourself

C

Our modern working lives are ruled by the concept of competence.The idea that lies behind competence is quite simple:that one can state what people should do in behavioral terms,and then measure whether a person has succeeded in meeting that task or not.We rarely have a second thought about whether the idea of measuring and achieving competence is a good one or not.In fact,it is a controversial one.

Humans do not learn or work in ways that can be measured by the concept of competence.Take the example of a barista(咖啡师)who is being trained to make coffee.The job title of“barista”suggests a degree of skill in making coffee.However,baristas in large coffee chains are usually trained through competence-based qualifications.One part of these qualifications is to produce a cup of coffee to meet a minimum standard.It might have to achieve a certain taste and appearance.This might seem perfectly reasonable,but there are two reasons why such an approach to training baristas does not work.First,the production of a cup of coffee to a certain standard is a binary(二次元的)outcome.The baristas can either produce a coffee of a certain standard or they cannot.If they happen to produce the best cup of coffee in the world,it does not matter,as competence-based training does not reward outstanding performance.Likewise,producing the worst cup of coffee would be a fail in the same way as producing a cup just below the standard.In fact,competence is not interested in the process of producing a coffee at all—only the final binary outcome.

Second,if the barista does produce a coffee to a certain standard,competence is not interested in why the barista can do that.But humans are not machines that simply produce binary outcomes.We have bodies and minds which change through learning.

Yet we are increasingly forced to achieve competence in our schools and workplaces.We are not empty machines that simply produce binary outcomes.If we want to be true human in our learning and our workplaces,we need to be creative and special.Learning and innovation(创新)involve failure in aiming for something that is unusually good.Such things simply cannot be judged by the standard of competence

where the mediocre is the gold standard.

28.Why is the approach to training baristas unreasonable in the author’s eyes?

A.It makes the outcomes rather unexpected.

B.It encourages low standards in workplaces.

C.It can’t improve baristas’motivation in work.

D.It ignores the fact that humans are not machines.

29.How does the author argue his main point?

A.By giving an example and explaining.

B.By criticizing the opposite point.

C.By examining differences.

D.By offering statistics.

30.What does the underlined word“mediocre”in the last paragraph probably mean?

A.Special skill. B.Great creativity.

C.Average quality.D.Outstanding ability.

31.What is probably the main purpose of the author in writing the text?

A.To introduce new forms of learning and training.

B.To explain how people learn and work nowadays.

C.To state human beings’advantages over machines.

D.To deny the general rule of measuring competence.

D

They say the average person makes 35,000 decisions a day.Yet in her new book,How Woman Decide,Therese Huston explores a widespread phenomenon that many women fail to notice.“There’s a huge double standard when it comes to how men and women are viewed as decision makers,”explains Therese,a psychologist from Seattle University.Therese decided to write the book after looking at her bookshelf:At one end,there were bestselling books about how to be a brilliant decision maker—all written by men and featuring interviews with men like athletes.At the other end were books aimed at women on gaining leadership skills and confidence.

“Once those women are at the table,will their decisions be taken as seriously as men’s?”Therese wondered.“Men are respected as decision makers more than women,especially in the workplace,largely because there’s this cultural belief that women are unable to make smart choices at work.”

So,Therese set out to pick apart the stereotypes(固有印象)to see what scientific research had found.“Scientific research shows that men and women struggle with decision-making equally.The only disadvantage I found was that during the teenage years-teenage girls are more indecisive than teenage boys.Otherwise,there’s little difference between the genders(性别).”

However,there are some differences.“Women are more collaborative(协作的),”says Therese.“A female boss is more likely to ask the opinions of those around her when making a choice.Women ask for input,which helps make better decisions.However,this is often seen as a

weakness rather than a strength.”

Therese also found that during times of stress,men and women make different choices,and the outcomes are often better when women are involved.

Study after study backs this view up.Neuroscientists Mara Mather and Nicole Lighthall from the University of Southern California studied the way men and women make decisions and found that in times of stress,they react very differently.

During their study,which involved playing a virtual gambling(赌博)game,they found that when the females became stressed,they made smart decisions—quitting while they were ahead or taking safe bets.But when the men became stressed,they did the opposite,risking everything for a slim chance of a big win.

32.Why did Therese Huston write her book How Women Decide?

A.Women are less respected as decision makers.

B.Women are not equally treated in workplaces.

C.Women are unable to make smart choices.

D.Women are poor at making big decisions.

33.What is women’s weakness in decision—making according to Therese Huston?

A.Men can make quicker decisions than women.

B.Women easily get stressed when making decisions.

C.Women are likely to ask for input when making decisions.

D.Teenage girls are 1ess able to make decisions than teenage boys.

34.What can we infer from the last paragraph?

A.Women show less confidence in times of stress.

B.Men tend to make risky in times of stress.

C.Men demonstrate great bravery in times of stress.

D.Women quit making decisions when ahead in games.

35.What’s Therese’s final conclusion according to the text?

A.Women are brilliant as decision makers.

B.Men are weaker in making smart decisions.

C.We should give up all cultural beliefs about gender.

D.Great difference exists between the two genders in decision—making.

河北省衡水中学2018届高三十六模理综 生物试题 一、选择题 1. 下列关于细胞内含磷化合物的叙述,错误的是 A. 为生命活动直接供能的“通货”是含磷化合物 B. 对细胞代谢具有催化作用的酶都是含磷化合物 C. 组成细胞膜、核糖体、染色体都有含磷化合物 D. 人体维持内环境pH的稳定有含磷化合物参与 【答案】B 【解析】为生命活动直接供能的“通货”是ATP,为含磷化合物,A正确;对细胞代谢具有催化作用的酶,大多数是蛋白质,少数是RNA,其中蛋白质不一定含有磷,B错误;组成细胞膜的磷脂分子、组成核糖体的RNA、组成染色体的DNA都是含磷化合物,C正确;人体维持内环境pH的稳定有含磷化合物参与,如缓冲物质磷酸氢二钠和磷酸二氢钠,D正确。 2. 下列有关细胞内物质含量比值的关系,正确的是 A. 细胞内结合水/自由水的比值,种子萌发时比休眠时高 B. 人体细胞内02/C02的比值,线粒体内比细胞质基质高 C. 神经纤维膜内K+/Na+的比值,动作电位时比静息电位时高 D. 适宜条件下光合作用过程中C5/C3的比值,停止供应C02后比停止前的高 【答案】D 【解析】种子萌发时细胞代谢旺盛,自由水含量多,细胞内结合水/自由水的比值比休眠时低,A错误;人体细胞在进行有氧呼吸时,每分解1摩尔的葡萄糖,则在线粒体基质中产生6摩尔的CO2,在线粒体内膜上消耗6摩尔的O2,人体细胞在进行无氧呼吸时,既无CO2的产生有无O2的消耗,B错误;神经细胞内K+浓度明显高于膜外,而Na+浓度比膜外低,静息电位的产生与维持主要是由于K+外流,动作电位产生的机制是Na+内流,所以K+/Na+的比值,动作电位时比静息电位时低,C错误;光合作用的暗反应阶段,首先发生CO2的固定,即CO2与C1化合物结合生成C2,随后在光反应产生的ATP提供能量的前提下,C2被光反应的产物[H]还原,所以适宜条件下光合作用过程中C1/C2的比值,停止供应CO2后比停止前的高,D正确。 【考点定位】细胞代谢 3. 科技工作者在广西发现了可能是现代栽培水稻祖先的万年野生稻,它们不但抗病、抗虫害能力特别强,一穗可达千粒果实,而且可与近缘栽培水稻杂交产生可育子代,以提高栽培水稻的抗逆性和产量。下列叙

河北省衡水中学2018届高三年级七调考试【答案打印版】

河北省衡水中学2018届高三上学期七调考试 语文试题参考答案 2018年3月30日1.B(A.“这说明审美价值重于实用价值”。原文句子“中国的陶瓷闻名遐迩,丝绸远销世界,古代建筑令人陶醉,皆因实用价值与审美价值相得益彰。”C.错在“说到底就是为了增强科技产品的竞争力”。原文说“凝聚着美……给人更多便利感受和美的体验”。D.错在“多些技术的诗意,实质正是遵守技术伦理,把创意和人文有机融合。”偷换概念。)2.B(错在“是为了说明人文要素比效率、性能更重要”。两者之间是相得益彰,互不缺少的关系。缺少“效率、性能”的科技,没有使用价值。而缺少“人文要素”的科技创新美感。) 3.A(错在此句表述本身就是错误。“某些技术成果缺少良好的用户体验的根本原因在于设计者在“贪多求快的浮躁心理驱使下主动放弃了对诗意的探求”。) 4.A(牧羊人对“我”的怀疑和不相信,是因为汉人疯狂采伐石头,不仅对当地地貌造成不可逆转的破坏,也对当地游牧民族人们的价值观带来了冲击,起了贪念的是疯狂采伐石头的汉人。) 5.答案:①人类疯狂开采石头,对戈壁滩的地貌造成了极大的伤害,但所开采的石头制作成商品后在城市售卖,价格却十分廉价。②人类因贪婪对大自然造成了不可逆转的伤害,这种伤害让人感到“哀凉无望”。③现代文明对游牧文明的价值观带来了冲击。(第一、二点,每点2分,第三点1分。) 6.答案:因为“我”深深认识到: ①“我”虽然喜爱石头,但不能把“喜爱”变成“贪婪”而去占有不属于自己的石头; ②触碰石头不仅会改变一只虫子的命运,甚至可能会改变更多——季节、气候、降雪量等,从而造成各种自然灾害。 ③戈壁玉的确美丽,但一旦离开荒野,离开纯粹的蓝天和粗砾的大地,它的美丽便迅速枯萎(每点2分。) 7.A(本题考查文本内容的理解分析。本题要求找出不属于该书观点的一项。题中A 错在遗漏信息,林风眠被誉为“百年巨匠”之一的原因很多,“奠定了中国现代绘画的基础”和“培养了很多大师级的名家”等也不可忽视。) 8.B、E(本题重点考查学生把握文章内容和筛选文章信息的能力。找到答题区间,筛选关键词句,概括形成答案。A.林风眠从小接受了良好的教育,既在学校接受了系统的文化学习,又在梁伯聪、南洋回来的朋友等人的影响下关注西方的艺术世界,这为他日后进行中西调和的创新打下了基础。C.为接受了“西方现代艺术和思想的双重启蒙”,中国传统艺术的启蒙他幼时就接受了。D.无中生有,林风眠出国留学、在国外艺术展上一举成名并未提到他的爱国情怀。) 9.①保持好奇心,善于学习。无论是中国的传统艺术、西洋插画,还是西方的艺术理论与思想,林风眠都兼收并蓄。 ②善于创新,能打破传统。林风眠不一味地做守规矩的“好学生”,才能在复兴东方岂术和调和东西艺术方面走出了一条自己的路。 ③贴近生活,保持人味。他的画作直接描述生活,拷问人性,富有活力。 ④耐住寂寞,专心创作。林风眠在上海不问世事埋头作画,最终让自己的艺术达到前所未有的高度。 ⑤有师友亲人的帮助。梁伯聪将林风眠引向了艺术的新天地,蔡元培的任人唯贤,父亲的影响,等等,都促成了林风眠的成功。 10.C(抓住关键主语“帝”“言官”和关键词“使”“再”。) 11.D(“汉武帝”是谥号。谥法制度有两个要点:一是谥号要符合死者的为人,二是谥号在死后由别人评定并授予。君主的谥号由礼官确定,由即位皇帝宣布,大臣的谥号是朝廷赐予的。谥号带有评判性,相当于盖棺定论。) 12.B(“余懋衡和王基洪等御史官先后把这件事上奏皇帝弹劾梁永”与文中内容不符。由原文“永虑军民为难,召亡命擐甲自卫。御史王基洪声言永必反,具陈永斩关及杀掠吏民状。巡抚顾其志颇为永讳,永乃藉口辨。帝疑御史言不实。”可以推测。)
