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. 【2】

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. 【3】

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".

【4】 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. 【5】 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.

Building Trust in a Relationship Again
Trust is a learned behavior that we gain from past experiences.（1）Trust is a risk.But you can't be successful when there's a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.21·cn·jy·com
Unfortunately，we've all been victims of betrayal.Whether we've been stolen from，lied to，misled，or cheated on，there are different levels of losing trust.Sometimes people simply can't trust anymore. （2）It's understandable，but if you're willing to build trust in a relationship again，we have some steps you can take to get you there.
●（3）Having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well－being.
●（4）If you've been betrayed，you are the victim of your circumstance.But there's a difference between being a victim and living with a “victim mentality”．At some point in all of our lives，we'll have our trust tested or violated.
●You didn't lose “everything”．Once trust is lost，what is left？Instead of looking at the situation from this hopeless angle，look at everything you still have and be thankful for all of the good in your life.（5） Instead，it's a healthy way to work through the experience to allow room for positive growth and forgiveness.

In the early twentieth century, there were close to ten million elephants, and now the elephant number is as low as 252,000 and expected to drop down to 160,000 by 2025. Between 2007 and 2014, the elephant population fell by at least 30%, or 144,000 elephants. As researchers have traveled over the African plains, they only spotted one herd of 36 elephants in an area like the size of Mexico. It is clear that these gentle mammals are disappearing right before our eyes.

There are many reasons why the elephant population has been decreasing, one of which is their habitat. Humans are competing with elephants for living space, and as more and more humans clear the land that is being used by elephants, the elephants have less space. Elephant hunting or "poaching" has been a major factor for the disappearance of this species, and they are killed only for their valuable ivory tusks. Although the trade of tusks is illegal, it is still a common practice in many places.

Often, all the local people living among elephants would be farmers, and found that they could make more money by selling the tusks of one elephant, than doing manual labor for twelve years. That alone makes it really hard to prevent them from killing the elephants.

Some places such as Botswana, have put in extra effort to protect their wildlife from poachers by founding their Botswana Defense Force, which is made up of around 700 specially-trained soldiers that are stationed in 40 different areas.

However, that is not the point of this article. Two different natural disasters in two different parts of the world have happened in the past few weeks. One was a major flood that has hit Louisiana in the United States. The other was an earthquake that hit Amatrice, Italy. However, there is a major difference in the news coverage of the two tragedies.

As for the flooding in Louisiana, it is reported that this disaster is the worst to hit the United States since Super-storm Sandy and it'll cost at least $30 million. In only the first couple of weeks, 13 people had died. However, like me, many people did not hear about this tragic event. I did not learn about it until about three weeks after it happened.

In Italy, however, it covered all media instantly. The earthquake in Italy happened on Tuesday morning. That same day, I was on Twitter and that was all that was over the news feed. Every other post was about the earthquake. Some would have the opinion that Amatrice, Italy was one of the most beautiful towns in that country. I got in deep sorrow because there were more people killed in this quake than the flooding. So far, they have a total of 73 dead and over one hundred missing.

I understand that technically the earthquake in Italy was worse than the floods in Louisiana. However, I believe that if a natural disaster happens, they all should be equally covered and taken equally seriously. We are one world united and should be there for all of the people who are in need of help. We may not be able to accurately predict disasters but, we can surely lend a hand out for the needy.

【1】What really concerns the author about the two natural disasters?

A. The death and the injured. B. The media report.

C. The government's responsibility. D. Their economic loss.

【2】Why did the author learn about the flood so late?

A. He didn’t care about the flood.

B. He felt nervous about the news.

C. The media didn’t cover it in time.

D. The flood frightened the author a lot.

【3】What can be inferred from the passage?

A. Italy isn't good at predicting the natural disasters.

B. All natural disasters should be covered equally.

C. The world should be united into one instantly.

D. America should help Italy predict natural disasters.

【4】How is the text mainly developed?

A. By making a comparison. B. By following the time order.

C. By listing some examples. D. By analyzing the causes.
