北京卷2019英语

19年北京考英语卷和全国英语卷，哪个难？我觉得应该是全国英语比较难

The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams. We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it's too little, too late. By the time these “solutions" become widely available，scammers will have moved onto cleverer means. In the near future, it's not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real. 自动语音电话的问题已经变得如此严重，以至于许多人现在拒绝接听陌生号码的电话。到明年,我们收到的电话将有一半是诈骗电话。我们终于意识到问题的严重性，支持并开发了一组工具、应用程序和方案，用来阻止骗子打通电话。不幸的是，太少而又太晚。当这些“解决方案”被广泛使用，骗子就会采用更高明的手段。在不久的将来，不仅在屏幕上看到的电话号码有疑问，而且很快你会怀疑你听到的声音是不是真的。 That's because there are a number of powerful voice manipulation and automation technologies that are about to become widely available for anyone to use .At this year's I/O Conference ,a company showed a new voice technology able to produce such a convincing human–sounding voice that it was able to speak to a receptionist and book a reservation without detection. 这是因为有很多强大的声音处理和自动化技术将广泛投入使用。今年的I/O大会上,一家公司展示了一种新的声音技术，能够产生令人信服的人类发出的声音，可以和接待人员对话，预订房间而不被察觉。 These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches of personal information has led to a situation where scammers can easily learn your mother 's name, and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means. for example，that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller 's, ricking you into "confirming " your address，mother's name，and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually. 骗子追逐金钱，因此公司将受到最严重的打击。很多业务仍然是通过电话进行的，其中很多是基于信任和现有关系。语音处理技术可能会逐渐削弱这一点。 这些发展可能会使目前的自动语音电话问题变得更糟。自动语音电话令人头痛的原因与其说是数量，不如说是准确性。十年来个人信息的数据泄露导致骗子可以很容易地知道你母亲的名字，甚至更多。有了这些，他们能够进行有针对性的活动来欺骗你们。这意味着。例如，一个骗子可以用一个你看起来很熟悉的号码打电话给你，用一个听起来很像你银行出纳员的声音和你说话，让你“确认”你的地址、母亲的名字和卡号。骗子紧跟着就会骗钱，公司将受到最严重的打击。许多业务仍然是通过电话完成的，其中许多是基于信任和现有的关系。语音处理技术可能会逐渐削弱这一点。 We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications—using apps like FaceTime or WhatsApp, which can be tied to your identity. 我们需要解决电信网络的不安全性。电话运营商和消费者需要共同努力，找到方法确认电话内容是真实的并且沟通也是真实的。这可能意味着要开发一种统一的方法来标记视频和图像，显示何时何人所作，或者干脆放弃电话，转向基于数据的通信——使用FaceTime或WhatsApp等应用，这些应用可以与你的身份绑定。 Credibility is hard to earn but easy to lose, and the problem is only going to harder from here on out. 信用很难获得，但容易失去，从现在开始，问题只会变得更加严重。

By the end of the century，if not sooner，the world's oceans will be bluer and greener thanks to a warming climate，according to a new study. 根据一项新的研究，到本世纪末，如果没有更早的话，由于气候变暖，世界海洋将变得更蓝更绿。 At the heart of the phenomenon lie tiny marine microorganisms called phytoplankton. Because of the way light reflects off the organisms，these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue，depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas，while reducing it in other spots，leading to changes in the ocean's appearance. 这种现象的核心是被称为浮游植物的海洋微生物。由于光从生物体反射的方式，这些浮游植物在海洋表面形成了五颜六色的图案。海洋的颜色从绿色到蓝色不等，这取决于浮游植物的种类和浓度。气候变化将在某些地区助长浮游植物的生长，而在其他地区则会相反，这导致了海洋外观的变化。 Phytoplankton live at the ocean surface，where they pull carbon dioxide into the ocean while giving off oxygen. When these organisms die，they bury carbon in the deep ocean，an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean's warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth，since they need not only sunlight and carbon dioxide to grow，but also nutrients. 浮游植物生活在海洋表面，在那里它们将二氧化碳吸入海洋，同时释放氧气。当这些生物死亡时，碳就会埋在深海中，这是一个有助于调节全球气候的重要过程。但浮游植物很容易受到海洋变暖趋势的影响。变暖改变了海洋的主要特征，并可能影响浮游植物的生长，因为它们的生长不仅需要阳光和二氧化碳，还需要营养物质。 Stephanie Dutkiewicz，a scientist in MIT's Center for Global Change Science，built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃，it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters，such as those of the Arctic，a warming will make conditions riper for phytoplankton，and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ”she said，“but the type of phytoplankton is changing. ” 麻省理工学院全球变化科学中心的科学家斯蒂芬妮·杜特凯维奇建立了一个气候模型，预测整个世纪海洋的变化。在一个温度升高3℃的世界里，会发现海洋的颜色发生多重变化。该模型预测，目前几乎没有浮游植物的蓝色区域可能会变得更蓝。但在一些水域，如北极水域，变暖将使浮游植物生长条件更加成熟，这些地区将变得更加绿色。”不只是海洋中浮游植物的数量在变化，”她说，“浮游植物的种类也正在改变。”
