Do you want to take time to get in touch with yourself, your feelings, your dreams, and a good, healthy life? Here are some tips:

    {#blank#}1{#/blank#} Sometimes it seems as if our culture has begun to view the need for sleep as a sign of weakness. But your body was genetically(基因地) programmed to spend a third of its life on sleep, and this affects thinking, memory, growth, your immune(免疫的) system and even your weight.

    Begin the day in thankfulness. {#blank#}2{#/blank#} Name each person and hold them in your thoughts. The sense of thankfulness you experience will set a peaceful tone for the entire day, and reduce a day's stress that can lead to sleeplessness that night.

    Strike a balance. {#blank#}3{#/blank#} Think about tai chi, prayer, yoga(瑜伽)—any daily activity that allows you to develop a peaceful center and a sense of balance.

    Play with friends. The "tend and be friend studies", as they are called, conducted by UCLA researcher, Shelly Taylor, Ph.D. indicate that when women are stressed, they tend to their children and play with other women. {#blank#}4{#/blank#}

    Use guided imagination. {#blank#}5{#/blank#} The tone of your voice, pacing, music, and pictures will persuade your nervous system that it's time to calm down.

    When it comes to the Internet, passwords which people often use are under fire. {#blank#}1{#/blank#} Research has shown that passwords are not a very good way to protect sensitive information.

    People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the more complex they become, the more people are likely to forget their passwords. The longer the passwords are, the more easily forgotten they are.{#blank#}2{#/blank#} 

    Google is trying to kill off the password on Android devices by introducing the Trust API, which does what simple passwords cannot. It gives developers a framework for securing their applications using a number of security systems and metrics (指标)on the device. A Trust Score will be generated based on the metrics the device gathers. {#blank#}3{#/blank#} 

    The Trust Score will be generated based on both metrics like your device location, face scanning, fingerprint and so on. Taken one at a time, these metrics arc not secure. But taken together, these metrics will help define the real "you".

    {#blank#}4{#/blank#}  This summer, Google will be running tests with some banks to see if Trust API meets their needs before rolling out to all developers later this year. It may take another year for apps and popular sites to start using the Trust API.

    This is a pretty exciting change. Passwords have been around for long and although the security of systems has been improved, the convenience of systems hasn't been improved much. {#blank#}5{#/blank#}  Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

A. Google appears to have the best of them.

B. Actually it's been under fire for a long time.

C. People tend to care more about its advantages.

D. Google has already been testing this on the real world.

E. Google has proved that the system is more convenient.

F. Therefore, they use the same password for each application.

G. It'll allow or refuse your application based on your trust score.

    A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.

    The system, called Driver Alert, aims to reduce deadly road accidents by 20%—40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.

    Driver Alert is based on a computerized wristband (腕带). The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver's response.

    Tiredness is directly related to a driver's response time. Usually, a watchful driver would use about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.

    In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver's response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.

    The device has been delivered to the department's laboratories for testing. If these tests, scheduled for six months' time, are successful, the makers will bring the product to market within about a year.

    When the dog named Judy spotted the first sheep in her life, she did what comes naturally. The four-year-old dog set off racing after the sheep across several fields and, being a city animal, lost both her sheep and her sense of direction. Then she ran along the edge of cliff( 悬崖) and fell 100 feet, bouncing off a rock into the sea.

    Her owner Mike Holden panicked and celled the coastguard of Cornwall, who turned up in seconds. Six volunteers slid down the cliff with the help of a rope but gave up all hope of finding her alive after a 90-minute search.

    Three days later, a hurricane hit the coast near Cornwall. Mr. Holden returned home from his holiday upset and convinced his pet was dead. He comforted himself with the thought she had died in the most beautiful part of the country.

    For the next two weeks, the Holdens were heartbroken. Then, one day, the phone rang and Steve Tregear, the coastguard of Cornwall, asked Holder if he would like his dog bark.

    A birdwatcher, armed with a telescope, found the pet sitting desperately on a rock. While he sounded the alarm, a student from Leeds climbed down the cliff to collect Judy.

    The dog had initially been knocked unconscious(失去知觉的)but had survived by drinking water from a fresh scream at the base of the cliff. She may have fed on the body of a sheep which had also fallen over the edge. “The dog was very thin and hungry,” Steve Tregear said, “It was a very dog. She survived because of a plentiful supply of fresh water,” he added.

    It was, as Mr. Holden admitted, “a minor miracle(奇迹)”.

    Weaving hammocks is an art that takes a sharp eye, a skilled hand and lots of patience. But in Lenwood Haddock's case, being blind works to his advantage. His trained, sensitive hands are acutely aware of every step of the process. Since beginning his craft in 1986, Lenwood has woven about 145, 000 perfect hammocks.

    Lenwood lost his sight in 1973, at age 18, during a hunting accident. “My whole working career has been blind,” he says. He first found a job as a woodworker, but when that organization closed, the North Carolina Division of Services for the Blind connected him with Hatteras Hammocks. On his first day of work. “I did a total of one hammock,” Lenwood recalls, laughing. “And then I came home and lay down to sleep. I lift weights, but I wasn't as tough as I thought until I started weaving.lt takes a lot of energy, and you're standing up all day.”

    In time, however, Lenwood found he had a knack (窍门) for the job. At first he worked on-site at the company, but after a year Lenwood moved his operation to the home workshop where he had worked for 10 years during his woodworking days.

    There, he creates dozens of hammocks each week from ropes in a variety of sizes. One day, he realized the step counter on his phone recorded him walking eight miles without ever leaving his shop.

    The process of weaving a hammock involves making and catching hundreds of loops (环). A single missed stitch (织针) creates a hole that can widen and make the hammock uncomfortable or even dangerous to use. Experienced weavers miss loops sometimes, but to his company's knowledge, Lenwood has never turned in a hammock with even one dropped stitch. Lenwood's skilled fingers are quick to catch and fix any mistakes.

    The company has acquired other brands and changed its name to The Hammock Source. Today, it is the world's largest maker and seller of hammocks, all built by hand.

    However, Lenwood's routine has changed little. He works his fingers back and forth across the rows, looping the rope and pulling it. With every hammock, Lenwood presents himself a perfect product. “I'm not sure how sighted people do it,” he admits.

    Getting stuck in a traffic jam is one of the most boring problems for people living in big cities. The fact that you're moving so slowly leads too stress, anger and the wish that your car could just fly over the traffic like an airplane.

    Soon, however, that wish could come true .On May 8, US car-renting company Uber showed off what it described as "the transportation mode of the future: on-demand air transport," reported ABC News.

    According to Nikhill Goel, head of products for Uber Air, the company's air taxi service may launch test flights in the US cities of Dallas and Los Angeles, as well as Dubai in the United Arab Emirates, as early as 2020. If everything goes according to plan, passengers will be able to fly to work by 2023.

    When the Olympics comes to Los Angeles in 2028. Uber "expects to have hundreds, if not thousands, of its aircraft in the skies." Goel told Newsweek.

    So what would Uber's flying vehicles be like?

    They are small, electric aircraft that take off and land vertically (垂直地) , and they give off zero emissions (排放) and are quiet enough to operate in cities .

    Just like an airplane, the vehicles will have fixed wings to help them glide. But while a helicopter has just one big fixed rotor (定量). Uber's vehicles will have multiple rotors , which will help increase fuel efficiency (效率) while reducing emissions and noise.

    Because of these fixed wines and multiple rotors. Uber's flying taxis "should be quieter and safer than a helicopter." reported ABC News.

    However, the service still has a long way to go before it's ready to accept passengers. For example, to avoid any potential accidents. Uber is working with NASA to study air traffic control problems associated with low-flying aircraft. But just as Dubai's Mayor Betty Price said in a news release. "This program is revolutionary and future -oriented (面向未来的)."
