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(衡量標(biāo)準(zhǔn))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.

1.What is implied in the underlined sentence in Para. 2?

A. Users make mistakes in using passwords.

B. Users should know the purpose of passwords.

C. Users have learnt to say no to their passwords.

D. Users misunderstand the meaning of passwords.

2.How is the key part of the Trust API generated?

A. By taking one metric at a time.

B. By combining various metrics.

C. By developing security systems.

D. By analyzing complex passwords.

3.What can we know about the Trust system from the text?

A. It needs to be improved in the future.

B. It hasn’t been proven to be effective.

C. It will be used on Android devices first.

D. It is secure and convenient for the users.

4.What would be the best title for the text?

A. How does Google develop the Trust API?

B. Will the Trust API meet the users’ needs?

C. Will passwords soon be a thing of the past?

D. How do passwords protect personal information?

After giving a talk at a high school,I was asked to pay a visit to a special student.An illness had kept the boy home,but he had expressed an interest in meeting me.I was told it would mean a great deal to him,so I agreed.

During the nine-mile drive to his home,I found out something about Matthew.He had muscular dystrophy（肌肉萎縮癥）.When he was born,the doctor told his parents that he would not live to five,and then they were told he would not make it to ten.Now he was thirteen.He wanted to meet me because I was a Gold-medal power lifter,and I knew about overcoming obstacles and going for my dreams.

I spent over an hour talking to Matthew.Never once did he complain or ask,"Why me?"He spoke about winning and succeeding and going for his dreams.Obviously,he knew what he was talking about.He didn't mention that his classmates had made fun of him because he was different.He just talked about his hopes for the future,and how one day he wanted to lift weights with me.When we had finished talking,I went to my briefcase（公文包）and pulled out the first gold medal I had won and put it around his neck.I told him he was more of a winner and knew more about success and overcoming obstacles than I ever would.He looked at it for a moment,then took it off and handed it back to me.He said,"You are a champion.You earned that medal.Someday when I get to the Olympics and win my own medal,I will show it to you."

Last summer I received a letter from Matthew's parents telling me that Matthew had passed away.They wanted me to have a letter he had written to me a few days before:

Dear Dick,

My mum said I should send you a thank-you letter for the picture you sent me.I also want to let you know that the doctors tell me that I don't have long to live any more,but I still smile as much as I can.I told you someday that I would go to the Olympics and win a gold medal,but I know now I will never get to do that.However,I know I'm a champion,and God knows that too.When I get to Heaven,God will give me my medal and when you get there,I will show it to you.Thank you for loving me.

Your friend,

Matthew
