全国卷2019届高考英语一轮复习Unit4Astronomy:thescienceofthestars课时作业新人教版必修3

Unit 4 Astronomy:the science of the stars Ⅰ.阅读理解 A How often have you read a story that a friend or family member has sent you?Very likely you would have skipped the news had it not been pointed out to you. Traditionally newspapers and famous TV channels have been our source of authentic news.But these days with the popularity of social media,sharing stories is increasingly becoming a favorite source of news.In fact,research suggests that more than half the people get their news today from social media such as Facebook,Twitter and Google. Social media sites often aggregate contents for us to see based on trending topics—stories that have been viewed by many others as well as based on our own past searches and analysis of our lik es and dislikes.If you have liked kittens in the past,you may have noticed that you are seeing more news,blogs and analysis about kittens all of a sudden. While advocates of free speech do not want to control any voice,it is certainly harmful when it is difficult to separate truth from fiction.Imagine the influence of fake(虚假的) news when it begins to affect our own lives.Trus ting a piece of news,patients could very easily fall for wrong diagnosis; elders could give money to cheats and reputation of perfectly upright citizens could be easily ruined.What about when we research for a school project and base our analysis on false information or news? Mark Zukerberg has finally acknowledged the issue.Among several projects that the company is considering,Facebook is trying to take powerful measures to crack down on false news.This would include warning labels on fake contents.Fake news also makes a lot of profits from advertising.Google and Facebook have said they will limit advertising profits on their network from such sites. The bottom line—don't believe every word of what you read.Do more research from multiple (多样的) sources to ensure that the news is indeed true before you share with others. [语篇解读] 本文为一篇说明文。现在社交媒体充斥着大量虚假信息,这些信息的传播对人们的生活危害很大。为了治理这种现象,一些社交媒体已经采取了一些措施。 1.What does the underlined word “aggregate” in Paragraph 3 probably mean? A.Analyze. B.Cancel.

英语必修三Unit4Astronomy课文翻译

英语必修三Unit 4 Astronomy课文翻译 作者:未知来源:尚学苑2014-09-20 LIF HOW E BEGAN ON THE EARTH No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a "Big Bang" that threw matter in all directions.After that, atoms began to form and combine to create stars and other bodies. For several billion years after the "Big Bang", the earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were to make the earths atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface. Water had also appeared on other planets like Mars but, unlike the earth, it had disappeared later. It was not immediately obvious that water was to be fundamental to the development of life. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas. This produced a chain reaction, which made it possible for life to develop. Many millions of years later, the first extremely small plants began to appear on the surface of the water. They multiplied and filled the oceans and seas with oxygen, which encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others, called amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared for the first time. They produced young enerally by laying eggs. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed on the earth for more than 140 million years. However, 65 million years ago the age of the dinosaurs ended. Why they suddenly disappeared still remains a mystery. This disappearance made possible the rise of mammals on the earth. These animals were different from all life forms in the past, because they gave birth to young baby animals and produced milk to feed them. Finally about 2.6 million years ago some small clever animals, now with hands and feet, appeared and spread all over the earth. Thus they have, in their turn, become the most important animals on the planet. But they are not looking after the earth very well. They are putting too much carbon dioxide into the atmosphere, which prevents heat from escaping from the earth into space. As a result of this, many scientists believe the earth may become too hot to live on. So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.

第三方支付安全性及风险防范问题教案资料

第三方支付安全性及风险防范 一、第三方支付概念 第三方支付是阿里巴巴集团主席马云在2005年瑞士达沃斯世界经济论坛上首先提出来的,目前为止学术界还没有给出一个非常明确的概念。第三方支付是非金融机构从事金融业务的重要渠道,人民银行发布的《非金融机构支付服务管理办法》中将其定义为依托公共网络或专用网络,在收付款人之间作为中介机构,提供网络支付、预付卡的发行与受理、银行卡收单以及中国人民银行规定的其他支付服务的非金融机构。 从其形式上看,所谓第三方支付,就是具备一定实力和信誉的第三方独立机构提供的网络支付平台,它是以非银行机构的第三方支付公司为信用中介,以互联网为基础,通过与各家银行签约,使得其与商业银行间可以进行某种形式的数据交换和相关信息确认,实现持卡人或消费者与各个银行以及最终的收款人或者商家之间建立一个支付的流程。第三方支付通过其支付平台在消费者、商家和银行之间建立连接,起到信用担保和技术保障的作用,实现从消费者到商家以及金融机构之间的货币支付、现金流转、资金结算等功能。在网络交易中,买方选购商品后,使用第三方支付平台把货款支付给第三方,再由第三方通知卖家货款到达并要求卖家发货,买方收到商品并检验后通知第三方,由第三方将货款转至卖家账户。相对于传统的资金划拨交易方式,第三方支付可以对交易双方进行约束和监督,有效地保障货物质量、交易诚信、退换要求等环节,满足电子商务交易的安全性,为交易成功提供必要的支持。如支付宝、财付通等都属于此类平台。 与其他支付方式相比,第三方支付服务具有以下特征: (1)支付中介。第三方支付的具体形式是付款人和收款人不直接发生货款往来,借助第三方支付平台完成款项在付款人、银行、支付服务商、收款人之间的转移。第三方支付平台所完成的资金转账都与交易订单密切相关。 (2)中立、公正。第三方支付平台不直接参与商品或服务的买卖。公平、公正地维护参与各方的合法权益。
