The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator (发电机). The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity —roughly 15 minutes of cycling for someone of average fitness.

The Indian government may use 3D paintings as virtual speed-breakers on major highways and roads, in an attempt to check speeding and careless driving,and eventually make its deadly roads a little safer. “We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers,”India’s transport minister Nitin Gadkari tweeted.

The visual illusions (幻象) are supposed to encourage drivers to slow down automatically. Earlier this month, India had ordered the removal of all speed breakers from highways, which are considered to be a danger to safety for high-speed vehicles.

India has the highest number of road accident deaths in the world. According to the World Health Organisation, over 200,00 people are killed by road accidents due to poor application of road safety laws. This is considerably higher than its official figures of 141,526 for 2014.

The use of visual illusions as speed breakers was first pioneered in the American city of Philadelphia in 2008, as part of a campaign against speeding motorists. The technique has also been tried out in China to create floating 3D crossings.

In India, cities such as Ahmedabad and Chennai have already experimented with 3D zebra crossings in the last one year. In Ahmedabad for instance, two artists, mother and daughter have painted 3D crosswalks in the first few months of this year. The artists say their motto i s “to increase the attention of drivers”, and that the concept has been successfully tested in zones where accidents easily occur on a highway.

However, critics argue that once drivers know that these speed breakers are visual illusions, they may ignore th em. Others also point out that India’s decision does not consider the safety of a large number of walkers. In the end, the new policy may be just one step towards improving road safety.

29. Accoding to the passage, 3D paintings as virtual speed breakers in India aims to .

A. Repalce all speed breakers from highways.

B. Encourage essential requirements of speed breakers.

C. Check speeding and careless driving on all highways.

D. Remind divers to speed down voluntarily for road safety.

30. What caused the high number of road accident deaths in India?

A. Speeding motorists.

B. Floating 3D crossings.

C. Free use of visual illusions.

D. Bad application of traffic laws.

31. The author explains the experiment of 3D zebra crossings in India by .

A. giving examples.

B. analysing causes.

C. providing figures.

D. making parisons.

32. What’s the author’s attitude towards 3D zebra crossings?

A. Subjective.

B. Objective.

C. Supportive.

D. Critical.

D

Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh and the more reasons there are, the more powerful the joke will be.

I was attending a stand-up edy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn’t only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.

The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren’t jealous of him.

In short, we don’t laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person’s emotions, he will certainly like it a lot.

33. What did the author find out after studying psychology?

A. Only good jokes make people laugh.

B. Many factors lead to people laughing.

C. Funny things can make people laugh.

D. Laughter can make people healthy.

34. Why did the audience laugh loud at the pedestrians?

A. They played a trick on the pedestrians.

B. The pedestrians behaved in a funny way.

C. They could fe el the pedestrians’ happiness.

D. Their emotion was approved of by the show.

35. What does the underlined word “belittling” probably mean?

A. Praise.

B. Blame.

C. Look down on.

D. Make up to.

Dear Mike,

I’m very glad to have received the letter you sent me last week. I have been thinking about the question you asked me. From my point of view, you can choose to e to China after finishing your studies.

For one reason, China’s development over the past 30 years offers quantities of job opportunities for the young. What’s more, what you are studyi ng is badly needed in China nowadays. In fact, many big panies in our city are hoping to hire people like you.

For another reason, China is a country with so different cultures and traditions from the west that many foreigners enjoy living and working here. Why not e and join them? I’m sure you will adapt to the environment quickly. If you e here, I will do what I can to help you. So what are you waiting for?

I’m looking forward to your ing.

Best wishes.

C5的分解。CO2和O2在与R酶结合时具有竞争性相互抑制。下列分析正确的是 A.植物叶肉细胞内CO2的固定发生在叶绿体内膜上 B.R酶催化CO2与C5反应时需要[H]和ATP C.增大CO2浓度后,植物叶肉细胞内的C3/C5比值增大 D.增大O2/CO2的比值,有利于提高植物的净光合速率 5.将生理状态相同、大小相似的多只家兔均分为甲、乙2组,2组家兔分别注射一定浓度的胰岛素溶液和肾上腺素溶液,一段时间后检测发现甲组家免血糖浓度下降,乙组家兔血糖浓度升高。下列分析错误的是A.因缺少对照,该实验不能得出血糖浓度受激素影响的结论 B.实验开始前,应分别测量甲、乙两组小鼠的初始血糖浓度 C.实验过程中,甲组家兔可能会出现行动迟缓甚至昏迷等症状 D.肾上腺素可能具有促进肝糖原分解,升高血糖的功能 6.正常人16号染色体有4个A基因(基因型为AA/AA),均能独立编码正常肽链,a基因则编码异常肽链。每个血红蛋白分子均有2个上述肽链参与构成(异常肽链也能参与)。研究表明,当体内缺少1~2个A基因时无明显贫血症状,缺少3个A基因时有溶血现象,无A基因时,胎儿因无正常的血红蛋白造成胚胎致死。一对无明显贫血症状的夫妇婚后先后怀孕二胎,头胎胚胎致死,第二胎完全正常。下列分析错误的是 A.这对夫妇的基因型均为AA/aa B.这对夫妇的血红蛋白有2种类型 C.血红蛋白结构异常时可造成红细胞破裂 D.这对夫妇再生育完全正常孩子的概率为1/4 7.草莓在大棚内种植受光质影响较大。在大棚内总透射光照强度、温度、CO2浓度和湿度等相同的条件下,科研人员测得某品种香草莓在不同农膜(白膜为自然光质,对照组)大棚内,3个月后草莓叶片和果实的部分数据见下表,请回答下列问题: (1)与对照组相比,蓝膜、红膜大棚内草莓叶片细胞内色素含量对环境的适应性表现分别是 ______________________;依据表中数据,对蓝膜大棚内草莓叶片适应性变化的解释是_______________________。(2)依据表中光补偿点和光饱和点的数据分析,草莓在___________(填“白膜”蓝膜”或“红膜”)大棚中的生长反应是耐阴生性增强;为提高冬季大棚草莓的产量,除了选择适合的农膜颜色外,还可适当补充___________光源。

【全国百强校】河北省衡水中学2018届高三十六模理综生物试题(解析版)

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。)

Any type of hobby that you can think of can be found in Australia. The following are four top Australian pastimes. Fishing Fishing is probably one of the most popular free-time activities in Australia and many people love spending their free time waiting at the end of a rod for a fish to bite on their line. There is free public access to almost all beaches,canals and coasts,which means there are plenty of great places to fish. Surfing Another popular pastime of the Australians is surfing. Australia has a lot of beautiful surf spots,especially in Queensland. Queensland has some of the best surf beaches in the country such as Noosa Heads,Stradbroke Island,and Burleigh Heads,with the Gold Coast being the best known.
