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 are 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.

    Maybe you are an ordinary student. {#blank#}1{#/blank#}This is not necessarily so. Anyone can become a better student if he or she wants to. Here's how:

    Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First arrange your time for eating, sleeping, dressing, etc, then decide a good, regular (有规律的) time for studying. {#blank#}2{#/blank#}A weekly schedule may not solve all your problems, but it will force you realize what is happening to your time.

     Make good use of your time in class. {#blank#}3{#/blank#} Listening carefully in class means less work later. Taking notes will help you remember what the teacher says.

    Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day, read that material.{#blank#}4{#/blank#}  If you do these things regularly, the material will become more meaningful, and you will remember it longer.

    Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. The world won't end if you don't pass a test, so don't be over worried.

    {#blank#}5{#/blank#} You will probably discover them after you have tried these.

A. This will help you understand the next class.

B. You probably think you will never be a top student.

C. Don't forget to leave enough time for entertainment (娱乐).

D. No one can become a top student unless he or she works hard.

E. There are other methods that might help you with your study.

F. Take advantage of class time to listen to everything the teacher says.

G. Make full use of spare time to take note of what the teacher says in class.

    Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student, they always say, “My spoken English is poor.” {#blank#}1{#/blank#} I would like to suggest that there may be some reasons for their problems with spoken English.

    First, they fail to find suitable words to express themselves due to a limited vocabulary. {#blank#}2{#/blank#}However, you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow you as long as you use the words that you know.

    {#blank#}3{#/blank#}Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate following the rules for grammar and using the right words and spelling them correctly. However, in speaking your aim is fluency. You want to get your message across, to talk to someone in English, as quickly and as well as you can, even though sometimes you may use a wrong word or tense, but it doesn't matter. {#blank#}4{#/blank#}

    The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All that hearing is necessary for you to start speaking.

    Fourth, most Chinese students are reactive rather than proactive(主动的) language learners. Instead of actively seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them and wonder why their English always remains poor. {#blank#}5{#/blank#}

A. The person you are speaking to will understand you and make allowances for any mistakes he hears.

B. Obviously the better answer is to expand their vocabulary.

C. They may try to avoid making similar mistakes next time.

D. If you have this proactive outlook, then you will see English opportunities wherever you go.

E. Second, they are afraid of making mistakes.

F. However, their spoken English does not have to remain “poor”!

G. The second reason lies in the reluctance of using what has just been learned.

    {#blank#}1{#/blank#} According to a new survey by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

    {#blank#}2{#/blank#} Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal. But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

    "More children are going to bed with TVs on, and there are more opportunities to stay awake, with more homework, the Internet and the phone," says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. {#blank#}3{#/blank#} Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

    Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. {#blank#}4{#/blank#} Students parents and teachers are pleased with the results.

A. How much sleep you need depends a lot on your age.

B. Other experts say part of the problem is chemical.

C. Getting less sleep has become a bad habit for most American kids.

D. what homework waiting for kids might always affects them sleep well every night.

E. Raising the minimum sleep is identified as a key way to help solve the problem.

F. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am.
