When it comes to the Internet, people talk about the password most. Actually, it's been under fire for a long time. 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 longer and more complex passwords become, the more people are likely to forger them. Therefore, they use the same password for every service or application. These are all big no-noes and essentially defeat the purpose of a password.

    Google is trying to kill off passwords on Android devices by introducing the Trust API, which does what simple passwords cannot and gives developers a framework for securing their application using a number of security systems and metrics(衡量标准)on the device. A Trust Score will be generated based on a number of metrics including your device location, face scanning, fingerprints, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not secure. But taken together, these metrics will help recognize the real “you”.

    The good news is that Google has already been testing this on real world data. Google has proven the Trust API works. Next Google will run tests will some banks to see if the Trust API meets their needs before rolling out the system on Android phones later. 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 a lone time. Although the security of systems has been improved, the usability of systems hasn't been proved much. Google appears to have the best of them. Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

    Modem zoos are different from those built fifty years ago.At that time zoos were places where people could go to see animals from many parts of the world.The animals lived in cages with iron bars（栅栏）.Although the zoo keepers took good care of them,many of the animals did not feel comfortable,and they often fell ill.

    In modern zoos,people can see animals in more natural conditions.The animals are given more freedom in larger places so that they can live as they would in nature.Even the appearance of zoos has changed.Trees and grass grow in cages,and water flows through the places the animals live in.There are few bars;instead,there is often a deep ditch（沟）,filled with water,which surrounds a space where several sorts of animals live together as they would naturally.In an American zoo,the visitors can walk through a special huge cage that is filled with trees,some small animals and many birds,and large enough for the birds to live naturally.In a zoo in New York,with the use of special nights,people can observe certain animals that are active only at night,when most zoos are dosed.Some zoos have special places for visitors to watch animals that live in the desert or under water.

    Modern zoos not only show animals to visitors,but also keep and save rare animals.For this reason,fifty years from now,the grandchildren of today's visitors will still be able to enjoy watching these animals.

    Thomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius,” Edison said. He said that what people called genius was mostly hard work.

    But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.

    Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.

    Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work,” he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

    Around the world, 62 million girls are not in school. The White House's Let Girls Learn effort aims to change that.

    At 13, Hawa Abdulai Yorke left her family's home, in Ghana, Africa, to live with an aunt who promised to send her to school. Instead, the aunt put Yorke to work as her maid. Determined to go to school, Yorke returned home and began selling water in a nearby city to raise
money for her education. She did that for three years. What hurt most was that her father had the money to pay the school fees. But he chose to spend the money on a motorcycle.

    Yorke's story is familiar to girls growing up in Ghana. There, a girl's place is in the home. Educating girls is considered a waste of money.

    “It happens more than it should, where parents have money to send their girls to school but choose not to,” says Ryan Roach, a Peace Corps volunteer in Ghana, where nearly 55% of girls are not enrolled in secondary school. “Cultural beliefs say education is not a wise investment(投资)”

    The White House's Let Girls Learn is working to change this view of girls' education, in Ghana and in countries worldwide. First Lady Michelle Obama says parents have to be persuaded that girls' education is a better investment than marriage or household labor. A World Bank study backs that up. It shows that for every year of secondary-school education, a girl's earning power increases by 18%.

    Today, Let Girls Learn works in 13 countries, and there are plans to expand the program. Recently, Let Girls Learn hosted a 24-hour event at which girls in different parts of Ghana joined Peace Corps volunteers, tech experts, and university students to brainstorm creative solutions for the barriers to girls' education. Yorke's team came up with an idea for an app that sends a recorded message to parents' phones from a Ghanian celebrity about the benefits of girls 
attending school.

    Yorke, now 22, is about to finish high school. Thanks to Let Girls Learn, she plans to attend college and study computer science. She says working alongside women college students at the Let Girls Learn event strengthened her determination. “I'm focused on my books,” says Yorke. "I know if I study hard, I, too, can go to the university and live a happy life."
