10、for my teeth so that my parents cant say no to it?” With that in mind, Moore asked her dad if she could start her own candy company.

17、s satisfied The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they dont know. By next year, half of the calls we receive will be scams(欺诈). We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps a

18、nd approaches intended to prevent scammers from getting through. Unfortunately, its too little, too late. By the time these “solutions”(解决方案) become widely available, scammers will have moved onto cleverer means. In the near future, its not just going to be the number you see on your screen that wil

19、l be in doubt. Soon you will also question whether the voice youre hearing is actually real.Thats because there are a number of powerful voice manipulation(处理) and automation technologies that are about to become widely available for anyone to use. At this years I/O Conference, a company showed a ne

Armed with this knowledge, theyre able to carry out individually targeted campaigns to cheat people. This means, for example, t

22、hat 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 tellers, tricking you into “confirming” your address, mothers name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is s

23、till done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.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 commun

24、icating 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 communicationsusing apps like FaceTime or WhatsApp, which can be tied to your identity.Credibili

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, dependin

29、g 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 oceans appearance.Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while givin

30、g 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 oceans warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they n

31、eed not only sunlight and carbon dioxide to grow, but also nutrients.Stephanie Dutkiewicz, a scientist in MITs 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 colo

32、ur 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.”And why
