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.

    Recently I had a conversation in Beijing with an adult Chinese friend who was complaining how difficult it was to study English. No surprises there. It is a difficult language to master, just like Chinese. I made a few suggestions based on my experience. One involved a very valuable fact which I learned from my high school Latin and Greek teacher, Dr. Smith．He is a gifted linguist （语言学家），and has an amazing ability to remember things, like poetry, essays, speeches, etc．His advice to us students is that for memorization purposes, there is forty minutes each day in which our memory is more acceptable than it is during the other 23 hours and 20 minutes.

    This 40-minute "super memory" period is divided into two parts: the 20 minutes before we sleep, and the 20 minutes after we first awake. The theory supporting this is pretty simple. First, the last information we input into our brain before bed has a better chance of taking root than information gained during the noisy daytime; and second, our mind is free of disturbance(干扰) when we first awake in the morning一so more receptive to inputs, like a blank slate（石板）．

    I took the advice to heart and it served me well in my school years. In my university days, our Chinese teacher would assign us 200 new vocabulary words each day, on which we would be quizzed（测试）the following day. Without the "magic" 40-minute technique, there's no way I would have passed those daily quizzes.

    As far as language study goes, it's not only useful for memorizing vocabulary. It's also a very useful window of time to listen to the language we're studying even with background noise, and even if it's at a level we find difficult to understand. It might be audio（声音的）language study, aids, or just radio, TV or whatever.

    Beyond our years of formal(正式的) education, memory skills are hugely important in any career. How many times have we heard a speaker read their speech from a prepared text, or read the word-by-word content of a PowerPoint presentation as they present each slide（投影片）? These are annoying, boring, and less effective ways of communicating. They are almost guaranteed(保证) to lose the audience's close attention and interest, let alone persuade or inspire anyone to do anything. And yet lots of people still make this mistake.

    If we use the 40-minute technique, we may not succeed in memorizing our presentation content on a 100% word-by-word basis, but we'll be familiar enough so that we can spend much more time making eye contact with our audience. We will get them in the process, while looking at our text instead of staring at it. This will also free up our hands and arms to convey some extra messages through gesture．

    As you see, the technique really works, but like many things, it takes practice to perfect it. Therefore, we'd better find ways to use the language outside of the classroom, as regularly and frequently as possible. One basic rule of language learning is, "Use it, or lose it·”

Seize the forty-minute learning window and we'll bring in a rich harvest of language learning.

    It may sound strange, but cutting down a real tree for Christmas is actually greener than going with the artificial kind, one scientist says.

    “It is a little confusing to people,” said Clint Springer, a biologist at Saint Joseph's University in Philadelphia. Because of concerns over deforestation（砍伐森林）around the world, many people naturally worry that buying a real tree might contribute to that problem. But most Christmas trees for sale these days are grown not in the forest but on tree farms for the purpose of being cut.

    Moreover, from the viewpoint of greenhouse gases, real trees are “the obvious choice”. Live trees actively release oxygen as they grow, and meanwhile remove carbon dioxide from the atmosphere. After they have been cut and Christmas is over, they're usually cut into smaller pieces for mulch（覆盖物）. As mulch, the bits of trees very slowly release carbon dioxide back into the atmosphere. So in the end, a real Christmas tree is carbon neutral, putting the same amount of carbon dioxide back into the air as it took out (although much more slowly).

    The tree farms that grow the trees also replant after the trees are cut.  Artificial trees, on the other hand, don't come out even in the carbon balance. Petroleum（石油）is used to make the plastics in artificial trees and lots of carbon dioxide-creating energy is required to make and transport them. Because these trees just end up in the places where waste is buried under the ground after use, “those greenhouse gases are lost forever,” Springer said.

    All people need to sleep. Sleep is a restorative(恢复健康的) process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.

    Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use the bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the possibility of your sleep being poor is rather high. Bedrooms should be designed, decorated and used for sleep only. TVs, computers and other things should not be in your bedroom if possible.

    Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before you go to bed. Develop a regular exercise program. Proper exercise and nutrition will help improve sleep patterns. However, avoid exercising 2 hours before bed, since this may stimulate your body and make it more difficult to fall asleep.

    Establish a pre-bedtime rule that will help you focus on sleep. You can try meditation(沉思), reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is best for you.

    Things such as room temperature, noise and light levels and even your bed mattress(床垫) can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interference(干扰).

    You probably know the basics of how comparatives(比较级) and superlatives(最高级) work in the English language. When comparing something, you often add an "-er" to the end of the comparative adjective. The general rule is that one-syllable(音节) words get the suffix(后缀), and polysyllabic words get "more" or "most." That is, unless the two-syllable word ends in a "y"; if that's the case, you will add the suffixes and change the "y" to an "i".

    But what about the word "fun"? This simple adjective only has one syllable, so you'd think you'd add suffixes on it to create superlatives. But if you were to say "I think Magic Kingdom is a funner park than Epcot." or "Disney World was the funnest vacation ever!" you might get some strange looks. It doesn't sound quite right. But…why? "Fun" is one syllable, so why do we choose "more fun" as the comparative—especially considering that the similar word "funny," which has more syllables than "fun," uses the suffixes with no problem?

    Well, the problem comes from the fact that the word "fun" was not originally an adjective. Until the early 19th century, it was mostly just a noun, and it gained its meaning as "amusement" in the 18th century. But as early as the 1800s, people began using it as an adjective, the way we'd describe "a fun time" or "a fun place" today.

    Basically, language is still developing. Grammarians have mostly come around to the use of "fun" as an adjective (though some dictionaries still call it informal). There was (and remains) an agreement of "Fine, you can use ‘fun' as an adjective…but, like, it's not really one, so it can't follow the rules of real adjectives." So they also agree that the answer to "is funner a word?" is yes. If you want to consider "fun," as an adjective, then "funner" is indeed a word, as is "funnest". But this doesn't mean that "more fun" and "most fun" are incorrect, though; in fact, in formal writing, you'll probably still want to use those instead of "funner" and "funnest."

    The English language is chock-full of uncertain grammar rules; there's no need to insist that a word breaks the common rules of language just because we didn't used to use it in a way we do now.

    What is the number one favorite pet in the UK? If you think the answer is dogs, you are wrong. There are 8.6 million cats and 8.3 million dogs in Britain according to recent figures. But experts predict that there will be more dogs than cats next year as dogs become more and more popular.

    Dogs as decorations

    We like to spend time with our pets. The Queen is famous for her affection for dogs and is often photographed with them. Nowadays some dog owners are more extreme — a few TV celebrities even take their dogs shopping or to restaurants. Chihuahuas are especially popular as "handbag dogs" because they are so tiny.

    Dog holidays

    People are also giving their pets holidays. Many UK hotels and holiday parks now welcome dogs as guests. What about owners who go abroad? They can leave their pets at a dog hotel or dog spa while they are away. Some even provide their dog guests with a TV.

    Dogs are for life

    The British charity, Dogs Trust, finds homes for thousands of lost and abandoned dogs every year. Their famous slogan "A dog is for life and not just for Christmas" was created in the 1970s to teach people about the responsibility of owning a dog. Dogs Trust told British people not to give dogs as gifts or treat them like toys.

    Dogs on TV

    Victoria Sitwell is the host of the popular TV programme called "It's me or the dog". In the show Victoria helps dog owners with their pets' bad behaviour. She tries to find solutions to problems such as a Dalmatian who thinks he owns the house and won't let the family sit on the sofa, dogs that will only eat ice cream and biscuits and even a bulldog who uses the owner's bed as a toilet.

    Fashion for dogs

    You can shop online or on the high street for the latest in dog clothes and accessories. Specialist shops sell items such as dog boots, dog fancy dress costumes, dog coats, dog dresses and dog pants.
