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.

    What makes a gift special? Is it the price you see on the gift receipt? Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?

    This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

    I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood, I felt that this was a gift that my father would truly appreciate.

    Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.

    Dubai(迪拜)is one of the economically richest places in the world. With its numerous malls, hotels, and beautiful beaches, Dubai has always been a popular holiday destination. This city was visited by around 5 million tourists each year. The government wanted to increase this number to 15 million. However, Dubai has only 45 miles of coastline, which is nowhere enough for so many people. To solve this problem, an island that looked like a palm tree was built in 2006, and named the Palm Jumeirah.

    The plan for the island was extraordinary. It was to host several hotels, shopping malls, restaurants, and homes. Although the initial plan was to build the island from concrete(水泥), a decision was taken to create it from sand and gravel(砾石), so as to give it a natural look.

    To make sure that this project was a success, the best engineers from across the world were employed. Engineers from Holland formed the majority in this group. To begin with, the engineers calculated the strength of storms at sea, and also the expected amount of rise in water levels due to global warming. And then they found that, the proposed location for the island was neither very wide nor deep.

    One of the difficulties the engineers came across was to put sand on the sea bed to create the breakwater(防浪堤).Finding the right sand for the project was also a daunting task, as the sand from Dubai's deserts was too fine. Instead, sand from the sea was used, as it was coarser(粗糙). Once the breakwater was built, construction of the island began.

    The Palm Island are really impressive in terms of engineering. However, these projects are so large that they may have changed the ecology of the region. Also, an immense amount of money and resources go into maintaining the islands, which is a major concern at the moment. Only time will tell if building the Palm Islands was actually a good decision.

    There are numerous amusement parks all over the world. A famous magazine, Amusement Today, does a survey among park lovers every year both in the US and overseas, based on which, "Top 5 List of the Best Amusement Parks in the World" has come out as follows:

    Are you looking for some new and exciting places to take your kids to? Try some of these places:

    Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand-made pieces, traveling exhibits, book signings(签名) by children's favorite writers, and even musical performances and other arts.

    Head to a natural history museum. This is where kids can discover the past from dinosaur models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared for kids and any special events that are coming up.

    Go to a Youtheater. Look for one in your area offering plays for child and family visitors. Pre-show play shops are conducted by area artists and educators where kids can discover the secret about performing arts. Puppet (木偶) making and stage make-up are just a couple of the special offerings you might find.

    Try hands-on science. Visit one of the many hands-on science museums around the country. These science play-lands are great fun for kids and grown-ups alike. They'll keep your child mentally and physically active the whole day through while pushing buttons, experimenting, and building. When everyone is tired, enjoy a fun family science show, commonly found in these museums.

Why do Chinese people love hot pot so much? As the winter months are coming in, more and more people are sitting around a table enjoying this kind of traditional meal. I find myself wondering what it is about this traditional meal, which has existed for more than 1, 000 years. What makes it a Chinese food favorite? It seems that the answer lies beyond the dish itself.

Hot pot isn't just designed to keep you warm during the cold months; it's also a social experience. It's a "theater" cooked food that turns a meal into an event. There is a lot of fun for everyone to have in adding some foods to the hot pot.

Hot pot is eaten over two to three hours. For this reason, it is often considered an evening's entertainment, and a time to spend with friends and families. However, many Westerners would be put off by the idea of other people sticking chopsticks in their food. When we come to eat at the table in the UK, we often have our own shares, although the experience is still a social one.

A similar experience to the hot pot can be found in Korean barbecue restaurants，which let you cook your own meat. This allows people to have their meat done however they want.

For most Westerners, the idea of going to a restaurant to cook their own food is very strange. But having a go, I find it's now one of my favorite meals in Beijing. The steam from the pot left my clothes smelling of food when I got home, but perhaps this was also part of the experience. When the cold wind is blowing outside, I am sitting around with my good friends, eating and drinking. For me it's like a dinner party where my taste buds (味蕾) and my appetite are equally satisfied in the warm company of friends.
