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.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation. {#blank#}4{#/blank#}Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

    Learning a foreign language can be interesting. {#blank#}1{#/blank#} In order to increase your chances of success, it is important to consider which method of language learning will provide you with the most benefits. So think about the three ways of learning a language: self­study at home, attending classes and online courses.

    The main disadvantage of learning by yourself is that there is no one available to answer your questions. One way to deal with this is to make a list of your questions and ask for the help of a native speaker of the language regularly. {#blank#}2{#/blank#}

    Learning a foreign language in a classroom is probably the most popular choice. The regularity(规律性) of the lessons will encourage you to attend classes. {#blank#}3{#/blank#} In most cases, the enthusiasm of the other students may also encourage you to make progress.

    Online learning is the newest method of learning a foreign language. It suits both the students who prefer to learn alone and the students who may prefer to attend a class but are unable to do so. {#blank#}4{#/blank#} It is also possible to ask questions and to communicate with other students online.

    Whichever method you choose, keep in mind the reasons why you are learning the language. {#blank#}5{#/blank#} This will help you stay focused throughout the learning process.

A.Many students prefer to learn by themselves.

B.But it can also be difficult, frustrating and boring.

C.You should also make sure you will benefit from it.

D.You will be able to ask the teacher questions face to face.

Should schools allow Halloween celebrations?

    Halloween is one of the most celebrated holidays in the United States. {#blank#}1{#/blank#} Many schools also celebrate the holiday by having kids dress up in costumes, take part in costume shows, and join in a variety of activities relating to Halloween. On October 31, the halls of schools across the country will be filled with princes, princesses, and superheroes. In addition to costumes, school Halloween celebrations often include classroom parties and trick-or-treating.

    {#blank#}2{#/blank#} They also say that dressing up in costumes allows kids to express themselves and show off their creativity.

    {#blank#}3{#/blank#} Officials at many of those schools say the celebrations are too time-consuming (费时的) and take away class time. They also point out that kids who can't afford costumes or who don't celebrate Halloween for cultural reasons feel left out. For example, Seth Boyden Elementary School in Maplewood, New Jersey, canceled(取消)its Halloween celebration last year. Officials at the school said that in the past, many students stayed home on that day.

    {#blank#}4{#/blank#} Bree Picower, a Professor of Early and Elementary Education at Montclair State, said, "Maplewood is a wonderful example of a school being responsive to society. Many schools plan to learn from it. Schools are places where students should feel included."

    Parents in Maplewood had different opinions of this policy. Some said that the new no-Halloween policy was a welcome change. {#blank#}5{#/blank#}

A. It brings a lot of safety problems.

B. Experts say Maplewood is not alone.

C. Many people dislike these costumes.

D. Each year there're millions of Americans celebrations the holiday.

E. But more and more schools have canceled(取消)Halloween celebrations in recent years.

F. Many teachers, parents, and students see these celebrations as a fun break from the school day.

    Do you have a place you've always wanted to visit? If the answer is yes, have you ever considered taking a trip alone there just for a few days?

    {#blank#}1{#/blank#}Although seeing the world on their own has always been a dream in their hearts since childhood, most people have repeatedly been told that the outside world is dangerous. The thought of going on a trip alone excites and terrifies them at the same time. Few end up stepping out of their comfort zone and going on meaningful adventures.

    It is normal to have some trouble traveling alone. {#blank#}2{#/blank#} For example, being alone on the road, you might have to ask strangers to take your photo wherever you go. If you join a tour halfway, you may be asked why you don't have friends or family around. {#blank#}3{#/blank#}

    First, traveling alone gives you a good opportunity to do everything you wish to do without worrying about others' needs and wants. If you want, you can read on a bench beside a river for the whole afternoon without being disturbed (打扰). You are free to walk around on different streets. {#blank#}4{#/blank#} You can also remove that dull daily routine (常规) that always makes you feel tired.

If you make good use of it, traveling alone can also be a wonderful journey of self-discovery, as you'll finally have time to think about your life.

    {#blank#}5{#/blank#} All you need to do is pack your bags, take your passport, gather up your courage and go somewhere. Go out and enjoy being alone, explore the unknown, make some friends, read a book, and get to know more about yourself and the world.

G. Traveling alone helps us figure out what we really want to fight for in this big world.
