Someone's always watching you online...

How do they get my information? Did you know that when you surf the Web, many websites put secret software on your computer? The software collects a large amount of information about you and sends it to Internet companies. The Internet companies sell it to other businesses. Your personal information can also be collected from social media（媒体）sites. There are many ways your information can be used.

What information do they collect and why? First, companies collect your information. The companies find out where you live, what websites you visit, and what you do online. With this information, they can guess other things about you. For example, they can guess if you are male or female, how old you are, and your interests. The companies use this information to decide which advertisements（广告）are best for you. Two people can go to the same website, but they will see different advertisements. For example, someone who likes sports could see an advertisement for sneakers, and someone who like films might see an advertisement for movie.

What do they do with my information? Your personal information could also be sold. Some companies collect information just so they can sell it to other businesses. A business that collects and sells personal information is called a data broker. When data brokers sell your information, a lot of different companies will know your online habits. Then these companies will advertise products or other websites to you.

What online habits are tracked（追踪）? Another way your personal information can be collected is through social media. When your information is on social media, a lot of people can see it. Even if you don't use social media, a friend might post a picture or video of you with your name on it. Pictures and videos can be shared for free on social media, which is one of the great benefits（福利）. However, that same act of sharing could be problem for your own security（安全）. If someone knows too much about you, they can steal your identity（身份）. Then they can buy things online and post messages while pretending（假装）to be you.

Conclusion. All of your online habits can be recorded. Studying people's online habits is big business. Your personal information is very valuable to companies. That is how they know who to send their advertisements to. The Internet reaches almost every corner of the world, but the danger is that your personal information might travel that far, too.

正确的，涂A：错误的，涂B。

1.All businesses collect a large amount of information about you online.

2.People who go to the same website may see different advertisements.

3.Data brokers collect your personal information for money.

4.If you don’t get online, your information will be safe.

5.Your personal information can go anywhere with the Internet.

Close friends, think alike?

"What! You, too? I believed I was the only one." Have you ever said something like this to someone? 1.

It seems that similarity often helps form friendship. The Greek thinker Aristotle once said, "People regard friendship as a matter of similarity; they say that we love those who are like our-selves." 2. Scientists from University of California said friends have similar behaviors, Scientific American reported.

The scientists invited 42 university students to take part in a test. Each student watched the same set of videos, which included a comedy, a discussion and a soccer match. 3.According to their scans, friends who watched the same video reacted in similar ways. Similar parts of their brains lit up while watching the videos, especially parts that are connected with motivation(动机), learning and memory. 4.

"Seeing one's friends have similar behaviors will reinforce(强化)one's own values, opinions, and interests," lead scientist Carolyn Parkinson told Business Insider. 5. Scientists from the University of Leipzig, Germany, found that friendship is also based on how physically close you are to someone. The scientists did a test with first-year college students the first time they met in class. In this test, students who sat in neighboring seats were more likely to become friends.

A.Now, there is some science behind this idea.

B.If so, you may have ended up becoming friends with this person.

C.Friends share a lot of similarities, though there are some differences.

D.But brain similarity is not the only thing that can result in friendship.

E.However, people who weren't friends had different reactions to the same videos.

F.At the same time, scientists scanned their brains and recorded their brain activity.

What’s going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10-30 years from now, according to the BBC.

Bionic（仿生的）Eyes

They are no longer something, only in a science fiction movie. People who are blind may have a chance to see things clearly—by wearing bionic eyes.

A blind eye can no longer sense sight, but a bionic eye can use a camera to “see” the environment and send information to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A bionic eye with very clear pictures could be just in a few years away.

Digital Money

We used to pay with cash for everything we bought. Now we can use Wechat Pay or Alipay to shop, money is spent without seeing it. That means we are already using digital money. People only need to take a mobile phone wherever they go. Using these ways is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.

It is reported that people in Sweden completely stopped using cash last year, and the US might be the next.

Self-driving Cars

Unlike a human driver, a self-driving car won’t be influenced by a phone call, the radio or something outside the window. Sensors（探测器）and cameras on the car would allow it to follow the rules of the road strictly and keep a safe space from other cars. This would greatly make the number of road accidents smaller. You can even take a short rest while the car drives itself. In the future, driverless cars would be widely accepted.
