Before birth, babies can tell the difference between loud sounds and voices. They can even distinguish their mother’s voice from that of a female stranger. But when it comes to embryonic learning (胎教), birds could rule the roost. As recently reported in The Auk: Ornithological Advances, some mother birds may teach their young to sing even before they hatch (孵化). New-born chicks can then imitate their mom’s call within a few days of entering the world.

This educational method was first observed in 2012 by Sonia Kleindorfer, a biologist at Flinders University in South Australia, and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs. When the eggs were hatched, the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me!” call.

To find out if the special quality was more widespread in birds, the researchers sought the red-backed fairy wren, another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analyzing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks, ranking them by similarity.

It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs, the more similar were the babies’ begging calls. In addition, the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom’s voice were rewarded with the most food.

This observation hints that effective embryonic learning could signal neurological (神经系统的) strengths of children to parents. An evolutionary inference can then be drawn. “As a parent, do you invest in quality children, or do you invest in children that are in need?” Kleindorfer asks. “Our results suggest that they might be going for quality.”

58.The underlined phrase in Paragraph 1 means“”.

A.be the worst

B.be the best

C.be the as bad

D.be just as good

59.What are Kleindorfer’s findings based on?

A.Similarities between the calls of moms and chicks.

B.The observation of fairy wrens across Australia.

C.The data collected from Queensland’s locals.

D.Controlled experiments on wrens and other birds.

60.Embryonic learning helps mother birds to identify the baby birds which .

A.can receive quality signals

A new commodity brings about a highly profitable, fast-growing industry,urging antitrust(反垄断)regulators to step in to check those who control its flow. A century ago, the resource in question was oil. Now similar concerns ares being raised by the giants(巨头)that deal in data, the oil of the digital age. The most valuable firms are Google, Amazon, Facebook and Microsoft. All look unstoppable.

Such situations have led to calls for the tech giants to be broken up. But size alone is not a crime. The giants’ success has benefited consumers. Few want to live without search engines or a quick delivery. Far from charging consumers high prices, many of these services are free (users pay, in effect, by handing over yet more data). And the appearance of new-born giants suggests that newcomers can make waves, too.

But there is cause for concern. The internet has made data abundant, all-present and far more valuable, changing the nature of data and competition. Google initially used the data collected from users to target advertising better. But recently it has discovered that data can be turned into new services: translation and visual recognition, to be sold to other companies. Internet companies’control of data gives them enormous power. So they have a “God’s eye view” of activities in their own markets and beyond.

This nature of data makes the antitrust measures of the past less useful. Breaking up firms like Google into five small ones would not stop remaking themselves: in time, one of them would become great again. A rethink is required — and as a new approach starts to become apparent, two ideas stand out.

The first is that antitrust authorities need to move form the industrial age into the 21st century. When considering a merger(兼并), for example, they have traditionally used size to determine when to step in. They now need to take into account the extent of firms’data

assets(资产) when assessing the impact of deals. The purchase price could also be a signal that an established company is buying a new-born threat. When this takes place, especially when a new-born company has no revenue to speak of, the regulators should raise red flags.

The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them. Companies could be forced to consumers what information they hold and how many money they make form it. Govemments could order the sharing of certain kinds of data, with users’ consent.

Restarting antitrust for the information age will not be easy But if govemments don’t wants

a data oconomy by a few giants, they must act soon.

61.Why is there a call to break up giants?

A. They have controlled the data market

B. They collect enormous private data

C. They no longer provide free services

D. They dismissed some new-born giants

62.What does the technological innovation in Paragraph 3 indicate?

A. Data giants’ technology is very expensive

B. Google’s idea is popular among data firms

C. Data can strengthen giants’ controlling position

D. Data can be turned into new services or products

63.By paying attention to firms’ data assets, antitrust regulators could .

A. kill a new threat

B. avoid the size trap

C. favour bigger firms

D. charge higher prices

64.What is the purpose of loosening the giants’ control of data?

A. Big companies could relieve data security pressure.

B. Governments could relieve their financial pressure.

C. Consumers could better protect their privacy.

D. Small companies could get more opportunities.

D

Old Problem, New Approaches

While clean energy is increasingly used in our daily life, global warning will continue for some decades after CO2 emissions(排放)peak. So even if emissions were to begin to decrease today, we would still face the challenge of adapting to climate change. Here I will stress some smarter and more creative examples of climate adaptation.

When it comes to adaptation, it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard, but to a constantly shifting set of conditions. This is why, in part at least, the US National Climate Assessment says that: “There is no ‘one-size fits all’ adaptation.” Nevertheless, there are some actions that offer much and carry little risk or cost.

Around the world, people are adapting in surprising ways, especially in some poor countries. Floods have become more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that serve as floating libraries, schools, and health clinics, and are equipped with solar panels and other communicating facilities. Rezwan is creating floating connectivity(连体)to replace flooded roads and highways. But he is also working at a far more fundamental level: his staff show people how to make floating gardens and fish ponds prevent starvation during the wet season.

Elsewhere in Asia even more astonishing actions are being taken. Chewang Norphel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers(冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel’s inspiration came from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves, Norphel calculates that he has stored about 200, 000m3 of water. Climate change is a continuing process, so Norphel’s ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.

Increasing Earth’s reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.

In Peru, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the life-giving ice. The outcome is still far from clear. But the World Bank has included the project on its of "100 ideas to save the planet”.

More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense. But some suggestions for adapting are not. When the polluting industries argue that we’ve lost the battle to control carbon pollution and have no choice but to adapt, it’s a nonsense designed to make the case for business as usual.

Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.

65. The underlined part in Paragraph 2 implies .

A. adaptation is an ever-changing process

B. the cost of adaptation varies with time

C. global warming affects adaptation forms

D. adaptation to climate change is challenging

66. What is special with regard to Rezwan’s project?

A. The project receives government support.

B. Different organizations work with each other.

C. His organization makes the best of a bad situation.

D. The project connects flooded roads and highways.

67. What did the Ice Man do to reduce the effect of global warming?

A. Storing ice for future use.

B. Protecting the glaciers from melting.

C. Changing the irrigation time.

D. Postponing the melting of the glaciers.

68. What do we learn from the Peru example?

A. White paint is usually safe for buildings.

B. The global warming tread cannot be stopped.

C. This country is heating up too quickly.

D. Sunlight reflection may relieve global warming.

69. According to the author, polluting industries should .

A. adapt to carbon pollution

B. plant highly profitable crops

C. leave carbon emission alone

D. fight against carbon pollution

70. What’s the author’s preferred solution to global warming?

A. Setting up a new standard.

B. Reducing carbon emission.

C. Adapting to climate change.

D. Monitoring polluting industries.

Population Change

Why is the world’s population growing? The answer is not what you might think. The reason for the explosion is not that people have been reproducing like rabbits, but that people have stopped dropping dead like flies. In 1900, people died at the average age of 30. By 2000 the average age was 65. But while increasing health was a typical feature of the 20th century, declining birth rate could be a defining one of the 21st.

Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays. Furthermore, around 50% of the world’s population live in regions where the figure is now below the replacement level (i.e. 2.1 births per woman) and almost all

developed nations are experiencing sub-replacement birth rate. You might think that developing nations would make up the loss (especially since 80% of the world’s people now live in such nations), but you’d be wrong. Declining birth rate is a major problem in many developing regions too, which might cause catastrophic global shortages of work force within a few decades.

A great decline in young work force is likely to occur in China, for instance. What does it imply? First, China needs to undergo rapid economic development before a population decline hits the country. Second, if other factors such as technology remain constant, economic growth and material expectations will fall well below recent standards and this could invite trouble.

Russia is another country with population problems that could break its economic promise. Since 1992 the number of people dying has been bigger than that of those being born by a massive 50%. Indeed official figures suggest the country has shrunk by 5% since 1993 and people in Russia live a shorter life now than those in 1961. Why is this occurring? Nobody is quite sure, but poor diet and above all long-time alcoholism have much to do with it. If current trends don’t bend, Russia’s population will be about the size of Yemen’s by the year 2050.

In the north of India, the population is booming due to high birth rates, but in the south, where most economic development is taking place, birth rate is falling rapidly. In a further twist, birth rate is highest in poorly educated rural areas and lowest in highly educated urban areas. In total, 25% of India’s working-age population has no education. In 2030, a sixth of the country’s potential work force could be totally uneducated.

One solution is obviously to import foreign workers via immigration. As for the USA, it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010—2030. Moreover, the USA has a track record of successfully accepting immigrants. As a result it’s likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term.

2017年高考试题大气部分

【2017全国卷I】我国某地为保证葡萄植株安全越冬,采用双层覆膜技术(两层覆膜间留有一定空间),效果显著。图中的曲线示意当地寒冷期(12月至次年2月)丰、枯雪年的平均气温日变化和丰、枯雪年的膜内平均温度日变化。据此完成1—3题。 1.图中表示枯雪年膜内平均温度日变化的曲线是 A.①B.②C.③D.④ 2.该地寒冷期 A.最低气温高于-16℃B.气温日变化因积雪状况差异较大 C.膜内温度日变化因积雪状况差异较大D.膜内温度日变化与气温日变化一致 3.该地可能位于 A.吉林省B.河北省C.山西省D.新疆维吾尔自治区 【答案】1.B 2.C 3.D 【解析】 1.四条曲线分别是当地寒冷期(12月至次年2月)丰、枯雪年的平均气温日变化和丰、枯雪年的膜内平均温度日变化。首先膜内有保温作用,应高于当地的实际温度。排除③④。枯雪年,降水少,总体温度低,昼夜温差大。丰雪年降水多,云层厚温差小,所以选②。 2.由上题判断可知,①表示丰雪年膜内平均温度日变化,②表示枯雪年膜内平均温度日变化; ③表示丰雪年平均气温日变化,④表示枯雪年平均气温日变化。由图可知,①②两曲线上下差异大,③④两曲线上下差异小,故膜内温度日变化因积雪状况差异较大,膜内温度日变化与气温日变化不一致。材料给的是平均气温,不是最低气温。 3.由图表可知,该地寒冷期最低气温可以接近-16℃,说明地理位置上较靠北,可能为华北北部、东北或西北;该地达到一日之内温度最高的时间是北京时间16时左右,而当地时间应为14时左右,且寒冷期(12月至次年2月)的日平均气温达到-16℃左右,所以应位于我国西北地区,即该地可能位于新疆维吾尔自治区。 考点:影响气温日变化和日较差大小的因素;经度与地方时。 【点睛】解答此题的关键是经度的确定,地方时的计算,一天中气温最高一般位于午后2点左右,当地地方时14点,从图中可以看出此时北京时间为16点左右,可知该地与北京的经度差30°,即该地大致位于东经90°,由此可以大致确定该地的地理位置。

(完整word)2019年江苏高考数学压轴题技巧

2017年江苏高考数学压轴题技巧 虽然我们认为最后一题有相当分值的易得分部分,但是毕竟已是整场考试的最后阶段,强弩之末势不能穿鲁缟,疲劳不可避免,因此所有同学在做最后一题时,都要格外小心谨慎,避免易得分部分因为疲劳出错,导致失分的遗憾结果出现。 2017年江苏高考数学压轴题技巧 1. 复杂的问题简单化,就是把一个复杂的问题,分解为 一系列简单的问题,把复杂的图形,分成几个基本图形,找相似,找直角,找特殊图形,慢慢求解,高考(微博)是分步得分的,这种思考方式尤为重要,能算的先算,能证的先证,踏上要点就能得分,就算结论出不来,中间还是有不少分能拿。 2. 运动的问题静止化,对于动态的图形,先把不变的线段,不变的角找到,有没有始终相等的线段,始终全等的图形,始终相似的图形,所有的运算都基于它们,在找到变化线段之间的联系,用代数式慢慢求解。 3. 一般的问题特殊化,有些一般的结论,找不到一般解法,先看特殊情况,比如动点问题,看看运动到中点怎样,运动到垂直又怎样,变成等腰三角形又会怎样,先找出结论,再慢慢求解。 需要掌握的主要的数学思想: 1. 方程与函数思想 利用方程解决几何计算已经不能算难题了,建立变量间的函数关系,也是经常会碰到的,常见的建立函数关系的方法有比例线段,勾股定理,三角比,面积公式等 2. 分类讨论思想

这个大家碰的多了,就不多讲了,常见于动点问题,找等腰,找相似,找直角三角形之类的。 3. 转化与化归思想 就是把一个问题转化为另一个问题,比如把四边形问题转化为三角形问题,还有压轴题中时有出现的找等腰三角形,有时可以转化为找一个和它相似的三角形也是等腰三角形的问题等等,代数中用的也很多,比如无理方程有理化,分式方程整式化等等 4. 数形结合思想 高中用的较多的是用几何问题去解决直角坐标系中的函数问题,对于高中生,尽可能从图形着手去解决,比如求点的坐标,可以通过往坐标轴作垂线,把它转化为求线段的长,再结合基本的相似全等三角比解决,尽可能避免用两点间距离公式列方程组。切记先用几何方法,实在做不出再用解析法。

一、2017新课标高考英语考试范围及考试结构 2017年高考英语科目从考试要求、考试形式和卷面结构来看均与2016年保持基本一致。最值得我们留心的仍然是完善新题型、突出考查综合语言运用能力。 【第一部分:听力】略 【第二部分:阅读理解】 2017年针对阅读依然是传统的四篇单选阅读加一篇七选五任务型阅读,重点考察考生对文章内容的细节理解、推力判断、词义猜测、主旨归纳以及文章逻辑的处理能力。 【第三部分:语言知识运用】 第一节:完形填空取材于现实,题材为记叙文。通过记叙的方式文章讲述了作者在大学期间学习手语的经历。 第二节:语法填空通过提示词和无提示词两种方式着重考察考生对实词和虚词的综合考察。 【第四部分:写作】 第一节:短文改错延续8:1:1的改错原则,8个改词,1个多词,1个缺词。考察重点和方式与往年区别不大。 第二节:书面表达整体中等难度,弘扬中国传统文化——唐诗。考察应用文中时间、地点及其他方面对遣词造句能力的综合表达能力。 二、2017年新课标高考英语试题命题特点 纵观2017英语试题,本次题目创新上比较少,整体中规中矩,没有出现偏难偏怪的题目,选项基本上平时强化练习都会涉及到。书面表达也比较容易,作答时不会出现太费力的地方。并且阅读题中设置的难点区分度并不是特别明显。因此整体上来说今年全国卷I英语整体难度较去年略有下降,但个别题目较新颖,考察灵活有设置适量陷阱。 三、2014-2017年新课标高考英语高考点分布及对比分析
