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.

Summer Camps

    83-year-old Antonio Vicente has spent the last four decades of his life fighting against the current. As Brazilian landowners cut down rainforests to make room for profitable (盈利的) plantations and cattle grazing grounds, he struggled to bring the thick jungles of his childhood back to life.

    In 1973 Antonio took up the challenge of restoring the forest on a 31-hectare piece of land that had been destroyed for cattle grazing. Ironically enough, he bought the land in Brazil's Sao Paulo region, using credits（贷款）that the military government was giving out to promote deforestation(砍伐森林) and agricultural technology. But Antonio didn't use the money to promote the national agriculture but wanted to revive the forest.

    "You are stupid. Planting trees is a waste of land. You won't have income. If it's full of trees, you won't have room for cows or crops," Antonio's neighbors told him. But he knew the damage caused by deforestation was far greater than financial profit. Antonio had grown up on a rural farm, and watched his father and the other villagers cut down forests at the owners' orders, either for charcoal production or to clear land for grazing cattle. He had watched the ancient water sources dry up and people struggling to survive.

    With only some donkeys and a few hired workers Antonio brought back the forest to his land. What started out as a weekend hobby soon became a permanent way of life. Antonio often recalls spending days and nights in his young jungle, surrounded by rats and foxes, and eating banana for breakfast, lunch and dinner.

    As the forest grew, the water returned, and Antonio says that there are now over 20 water sources on his land that were no longer there when he bought it. Then the animals started making a home there. Today, the forest is alive with sounds of birds and insects living there, and more species are settling in every year.

    Over the past few years I've had an uncomfortable sense that someone, or something, has been making changes to my brain. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Involving myself in a book or a lengthy article used to be easy. That's rarely the case any more.

    I think I know what's going on. For over a decade, I've been spending lots of time online. The Web has been a godsend to me as a writer. Research that once required days in the rooms of libraries can now be done in minutes by a few Google searches. Even when I'm not working, I'm scanning headlines or just tripping from link to link.

The Net is becoming a universal medium where information flows through my eyes and ears and into mind. The perfect recall of silicon memory (硅制存储器) can be a blessing to thinking. But that comes at a price. As the media theorist Marshall Mcluhan pointed out, media are not just passive channels of information. They supply the stuff of thought, but they also shape the process of thought. And what the Net seems to be doing is weakening my ability for concentration. Once I was a driver in the sea of words. Now I zip along the surface like a flying swallow.

I'm not the only one. When I mention my troubles with reading to acquaintances, Bruce Friedman, a blogger, also has described how the Internet has changed his mental habits. His thinking has taken on a "staccato (破碎)" quality. "I can't read War and Peace any more" he admitted, "I've lost the ability to do that."

A recently published study suggests that when reading online, we tend to become "more decoders (解码器) of information". We are not only what we read; we are how we read.

    My teacher, Mr. August J. Bachmann, was the most influential teacher I ever had.

    I had gotten into trouble in his class: Another student had pushed me for fun, and I became angry and began to hit him. Mr. Bachmann stopped the fight, but instead of sending me to the office, he sat me down and asked a simple question, "Penna, why are you wasting your life？Why aren't you going to college?"

    I didn't know anything about colleges or scholarships. No one had ever considered that a fatherless boy from the poorest neighborhood had a future. That day, instead of rushing off for lunch, he stayed and explained possible education options to me. At the end of our talk, he sent me to see a secretary who had a child at a state college. This was in 1962 at Emerson High School in Union City, New Jersey.

    Well, 55 years have passed, and what have I done with the knowledge he gave me？I gained a PhD from Fordham University when I was only 29.I taught English and social studies and then moved up the chain of command from teacher to principal(校长).

    I've sat on the board for Magnet Schools of America and represented that organization at the United Nations. I've won a number of great educational awards. But where would I be if a truly caring teacher had not taken the time out of his lunch period to speak to me? It was without question only his confidence in me that helped me forward.

    I have repaid his kindness hundreds of times by encouraging misguided youngsters to aim higher. If I have saved any children, it is because of him. If I have been a successful educator, it is because I had a great role model in Mr. Bachmann.

    The morning after an evening struggle to care for my three-year-old daughter, I couldn't wait to get her to school. I, as a mother, was tired from the anger and her inability to communicate because of her slowed language development.

    As I accompanied her into the car, I felt desperate. Nothing was right with our world. She'd been born around the same time when the nation was witnessing the birth of another Great Recession. My job and my house had been victims. Then this happened. My child's language delay was identified, but doctors struggled to properly help her, I felt like we both needed to he rescued.

    I returned that afternoon as disenchanted with the little girl 1 loved as when 1 left. Walking slowly toward the school's playground gate, I found her preschool teacher racing to greet me.

    “You should have seen her today!” His breathy words were supported by excitement. I didn't interrupt. “See that climber.” He pointed to a wooden piece of playground equipment that looked like a rock wall. I nodded. “Well, every day since she started school, she's tried and failed to make it to the top.” He took a breath. “And today she did it!”

    He expressed his joy just as he'd witnessed her conquering Mount Everest! “She cheered and celebrated! I wish I'd recorded it!” His words comforted me. My daughter had conquered her mountain.

    As she ran toward me, I recognized something I hadn't before. I saw her perseverance(毅力). I saw her strength. I saw a Hero.
