Ways Your Cell Phone Affects Your Body and Mind
First, some good news. Your phone can keep you safer. A study found that 137 more lives were saved per 100,000 patients when people called 911 from a mobile phone rather than from a fixed one.
Scanning your phone right before bed can cause sleep disorder. To avoid that, make a habit of not using your phone for at least 30 minutes before you close your eyes.
When you are awake, a single sound on your phone can signal the coming news. However, this can weaken your ability to focus on a task.
Memory suffers too.
It would be easy to avoid all these problems by simply putting down your phone. The problem: It isn’t so easy.
| A．But there are plenty of worries too. |
| B．Your phone can do damage to your eyes. |
| C．Silence your phone or simply put it away can help. |
| D．Walking with your face in your phone can be dangerous. |
| E．People may feel painful when separated from their phones. |
| F．Your hand may feel painful when you hold your phone too long. |

Get organized. By becoming more organized, you can reduce your stress level. Make a daily schedule of all your activities. Another way to become more organized is by getting your supplies and desk in order. Arrange your notes and assignments by topic or date so you can easily find information.
Don’t put off. Delaying doing your schoolwork will only make you more stressed. If you get an assignment that is due in a month, and you don’t have any other assignment to finish, go ahead and begin working on it.

【推荐3】If you’re afraid to fly, you’re in good company. About 40% of Americans feel some fear at the thought of flying.
Exposure therapy is the idea that being exposed to something you’re afraid of over and over again calms down your limbic system so it doesn’t fire up as fast. That could mean less anxiety in the long run.

【推荐1】Apple users who were easily upset about handing over their fingerprints now face an even more personal proposition (议题): unlocking their smart-phones with their faces. With Face ID, an iPhone X user simply holds up the device and it recognizes his or her face. “Nothing has ever been simpler, more natural and effortless,” said Phil Schiller. “Face ID is the future of how we unlock our smart-phones and protect our sensitive information.” It is convenient but perhaps a bit horrible.
The system relies on an advanced set of tech packed into the front of the new phone. The dot projector sends out more than 30,000 invisible infrared (红外线) dots, and the infrared camera seizes an image. Apple uses the infrared image and dot pattern and pushes them through neural(神经) networks to create a mathematical model of your face, and then it checks that mathematical model against a stored image seized earlier. Once it detects a match, the phone unlocks. Schiller said Apple took more than a billion images and multiple neural networks to create Face ID. iPhone X will come with an A11 bionic neural engine to process faces.To set it up, hold your iPhone X in front of your face and move your head slowly around. That will become the stored version on your phone.
Face ID is advanced enough to work in the dark, and to learn your face under different circumstances -- so go ahead and wear those fashionable glasses or grow that fashionable beard. Schiller said Apple also worked hard to ensure the technology can’t be easily tricked by things like photographs. “They’ve even gone and worked with professional mask makers and makeup artists in Hollywood to protect against these attempts to beat Face ID,” he said. The tech also requires users’ attention to unlock -- your eyes have to be open, and you can't be looking away, meaning your device should remain safe even if you’re asleep.
1. Face ID enables users _______.| A．to hold up the device with less difficulty |
| B．to unlock their smart-phones much easier |
| C．to protect the iPhone X from being stolen |
| D．to make it convenient to store information |
| A．What the facial recognition is. | B．Why iPhone X is very popular. |
| C．How iPhone X’s Face ID works. | D．Where the system create images. |
| A．expose it to the strong light | B．keep yourself wide awake |

【推荐2】You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot.
Xiaoice, Microsoft’s latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions young Chinese now exchange with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.
“People loved to talk with Xiaoice for her incredible learning ability,” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.
Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM’s latest artificial intelligence program serves as an academic consultant at Australia’s Deakin University, answering students’ questions about course schedules and financial aid. Apple’s Siri and Amazon’s Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.
These programs are expected to move beyond smartphones, into televisions, cars and living rooms, The New York Times pointed out. However, it may take decades before scientists develop a “Samantha”, the advanced chatbot seen in the fiction film Her. In the film, Samantha sparks a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers are enthusiastic about this fantasy of virtual soul mate.

【推荐3】Amazon will let customers at some Whole Foods stores pay with a simple wave of their hands.
The company announced it is bringing palm scanners (掌纹扫描仪) to one of its Whole Foods stores in Seattle, with plans to roll out the new payment system to eight stores in the Seattle area in the coming months. Customers will hold their hands above the scanner for a contact-free payment method.
The scanners are already available (可用的) at one of those Seattle stores — its Madison Broadway location. Amazon plans to increase availability further after this first test run. “We’re always looking for new ways to improve the shopping experience for our customers,” said Arun Rajan, chief technology officer at Whole Foods.
To make use of the new service, customers will give Whole Foods their bank card information to make a connection with their palm print. They can choose to use a different payment method, such as cash, check or other bank cards, in later visits.
Amazon has already tried the system, which it calls Amazon One, at some of its own stores in Seattle, including Amazon Go and Amazon Go Grocery, which have allowed customers to pick the things they want and then leave the store without checking out, as sensors (传感器) and cameras track their purchases.
That checkout-free technology has been criticized (批评) as a way to avoid the need for workers.
Whole Foods said this new palm scanner will not have any effect on employment in the stores where it is offered.
“Amazon One is an additional payment choice at checkout, and Whole Foods Market Team Members will continue to maintain all of their present responsibilities,” said the company’s statement.
1. What will happen in the next few months?| A．Amazon will open more Whole Foods stores. |

According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer－a single code consisting of a long series of numbers and letters－to record the computer user's age, gender, location, favorite movies and hobbies.
The newspaper reports that Lotame Solutions Inc., a New York company, uses an advanced software called “beacon” to capture what people are typing on a website.
Lotame packages that data into profiles (个人资料) about individuals, only without their names, and sells the profiles to companies seeking customers. Batches of such data may be sold for a few dollars.
The Wall Street Journal survey discovered that spying on Internet users is one of the fastestgrowing businesses on the World Wide Web.
The “cookie”－a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news. There are new and more complex tools such as “beacon” which scan in real time what people are doing on a webpage. These beacons instantly assess the Internet user's location, income, shopping interests and even medical conditions.
Millions of Internet users around the world also face unprecedented (空前的) threats. Private, sensitive, personal and business information is being gathered and sold without their knowledge.
Companies insist the information they gather is anonymous(匿名的) and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don't know that they were installing intrusive files on visitors' computers. These include MSN.com and Yahoo.com.
Next time you visit a webpage and find an ad banner advertising something you've been planning to buy, don't be amazed that your computer can read your mind.

【推荐3】E is a teen with special needs. Often, she feels that she is targeted by her schoolmates. She complains of dirty looks, eye rolling and whispering when she walks through the halls. This time, she saw A whispering and thought it was about her.
And E had power to hit back-on Facebook. As soon as she got home, she logged on and demanded that her friends unfriend A, and choose between the two of them. She teased them for talking to A at school, and called A “ugly” and “fat”, “She is smelly.” E wrote, “and she uses her Mum to fight her battles.” You can only imagine the comments.
However, E didn’t know that her Facebook privacy setting was set to the public which meant that anyone-including A-could read her posts. In a matter of hours, E was the cyberbully.
And here’s the thing about cyberbullying: It can become real-life trouble. This can often be heard. “You bother me online. I will bother you up on the bus.” It can start with a misunderstood comment or an inappropriate post meant as a joke, And for a teen with special needs, words can take on literal meanings, crcating an cnvironment that’s frightening. Combine that with a lack of control of online privacy and virtual social skills and you may have an ill outcome.
Social media can open doors to new friendships and social circles that are inaccessible in real life. But we, as adults, often give our children access to this virtual world without guidance and boundaries, while counting on them to use it with ease and wisdom. We expect too much with little direction. The advice that I give parents is to set clear rules and stay consistent, even repeated.
