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.

Think Positive and Feel Positive

    When you're in a stressful situation, are you confident or unsafe? Do you react positively or negatively?

    {#blank#}1{#/blank#}A study by researchers at the University of Notre Dame found that negative thinking, and depression coming from it, can be catching in certain circumstances.

    For example, the researchers studied 103 freshman college roommates who'd been paired casually.{#blank#}2{#/blank#}Specifically, the researchers measured the subject's likelihood to see negative events as a reflection of their abilities and disadvantages.

    After only six months, it became clear that thinking patterns and styles can be catching.{#blank#}3{#/blank#}And students paired with more positive thinking roommates were more likely to become more positive in their thinking and report less depression.

    {#blank#}4{#/blank#}So they might be particularly accessible to adopting the thought and behavior patterns of people around them — perhaps more so than people in less intense situations at other stages of life.

    But maybe not. Other research has shown that, in general, people are affected by how those around them think.{#blank#}5{#/blank#}

A. The answer may depend in part on whom you're around.

B. Now college freshman are in a unique, life changing environment.

C. However, think positive and feel positive is quite important for college students.

D. Students paired with a negative-thinking roommate “caught” that style and became more depressed themselves.

E. They measured each roommate's cognitive weakness, or tendency to give in to negative thinking and depression.

F. So surrounding a negative, depressed person with people who think positively could be a powerful form of treatment.

G. But what was to the researchers' embarrassment was that the subjects never talked with each and stayed apart from each other for most of the time.

    Please wear loose clothing, mostly cotton. It is obvious that wearing clothing that is loose rather than tight is welcomed in summer. {#blank#}1{#/blank#}. This carries away the warmth that your body produces and allows cooler air to flow back in.

    {#blank#}2{#/blank#}. When it's really hot out, materials that “breathe” — allowing the flow of air through the fabric (衣料) itself — also work to keep you cool. Cotton and linen are among the most breathable fabrics，so look for clothes made of those substances.

    Your body controls its temperature via a small peanut-shaped section of the brain known as the hypothalamus (下丘脑). {#blank#}3{#/blank#}. It turns the temperature up or down based on various factors — such as how cold or hot the skin is.

    Certain parts of the skin have a larger influence than others. {#blank#}4{#/blank#}. They get their name because you can feel your pulse there, and the reason you can do that is because vessels are so close to the edge of your skin that one can easily hear or feel the flow of blood.

    When you want to lower your body temperature, cooling those pulse points with cold water or ice sends a signal to the brain that says, “Turn cold.” {#blank#}5{#/blank#}. Focus on pulse points that are easy to reach: the insides of your wrists, the area around your temple, and your neck. Holding an ice pack or even a cold washcloth against the skin on these regions will make your entire body feel cooler.

A. It allows air to flow past the skin

B. Sweating helps to cool off the skin

C. These areas are called pulse points (脉冲点)

D. The type of fabric you wear has an influence, too

E. This fools your brain into turning down its thermostat (恒温器)

F. This region works almost like a thermostat in a home

G. Exercising in extreme heat is usually not recommended

    Word travels quickly in the small fishing village of Port Washington, Wisconsin. So when Mardy McGarry wanted to build a playground for kids with special needs, she knew it wouldn't take long to create interest in the project. But she never expected that a third of the town people would join in it.{#blank#}1{#/blank#}

    "A lot of learning comes through play," says McGarry, a special education teacher for 28 years. She'd seen the wood chips and sand of traditional playgrounds stop wheelchairs dead in their tracks.

    When a piece of land became available, the city council agreed to choose a part for a playground.{#blank#}2{#/blank#}She asked classrooms of kids for their wish list. She also asked experts for help. And she brought on board her friend Sue Mayer, whose eight-year-old son, Sam, has a serious disease.

    Her Kiwanis Club chapter came through with $ 7,000, and that's when the grassroots movement really got started. One woman gave $ 25,000 and had her company donate the same amount.{#blank#}3{#/blank#}There were silent auctions(拍卖) and T-shirt sales. The local Pieper Family Foundation offered to donate half of the remaining $170,000 balance if McGarry could raise the rest. The $ 450,000 covered materials, but the actual construction would cost an additional $ 900,000. Not a choice. But the community could build it.

    On September 16, 2008, the first day of construction, they came. Two women heard about the project on the radio on the way to work and took the day off to help.{#blank#}4{#/blank#}Ten-year-olds sanded surfaces.

    Today, Possibility Playground is one of the most popular destinations in Ozaukee County. There's a giant pirate ship, a rock-climbing wall, high and low rings, monkey bars, sandboxes, swings, slides, bridges and so on.

    {#blank#}5{#/blank#}It's exactly what McGarry wanted. People used to ask why she wanted to build a playground just for children with disabilities. "They didn't get it. It's only when you build a playground for children with disabilities that you build one for all children," she said.

A. Soon smaller businesses were helping.

B. All children play shoulder to shoulder.

C. But her students were too often left out.

D. Everyone thought it was really a great wonder.

E. A couple in their 80s operated their own trucks.

F. McGarry started researching play equipment and contacting design firms.

G. They rolled up their sleeves and used their weekdays to bring her idea to life.

    The history of writing instruments, with which humans have recorded and conveyed thoughts and feelings, is the history of civilization itself. This is how we know about our ancestors and their life.

    The handy sharpened-stone was adapted into the first writing instrument. Around 24 000 BC, the cave man started drawing pictures with the stone onto the walls of his cave. {#blank#}1{#/blank#} Walls at the Apollo site in Namibia are believed to be the oldest rock paintings to date.

    Before paper came along, people used clay or wax tablets on which they wrote with sharp objects such as metal sticks or bones. Around 6000 years ago, the Egyptians invented the first paperlike material called papyrus. The word "paper" actually comes from the word "papyrus".

    {#blank#}2{#/blank#} Bones or metal sticks were no longer useful as the papyrus could not be scratched. So the Egyptians created a reed-pen perfect for the papyrus. {#blank#}3{#/blank#} And thus, ancient Egyptians transformed bamboo stems (茎) into an early form of a fountain pen.

    Another writing instrument that remained active in history for a long period was the quill (鹅毛) pen. Introduced around 700 AD, the quill was a pen made from a bird feather. Goose feathers were most common. {#blank#}4{#/blank#} For making fine line drawings, crow feathers were the best.

    When writers had better inks and paper and handwriting had developed into both an art form and an everyday occurrence, man's inventive nature once again turned to improving the writing instrument. {#blank#}5{#/blank#}

A. Now something was needed to write upon the papyrus.

B. The papyrus became the most popular material at that time.

C. Swan feathers were of a high quality, being rare and most expensive.

D. Bamboo stems were better and much more expensive than goose feathers.

E. This led to the development of the modem fountain pen in the 19th century.

F. These were mostly the stems of grasses, especially from the bamboo plant.

G. These drawings showed events in daily life like the planting of crops or hunting victories.
