【推荐1】Facial recognition（人脸识别）cameras are everywhere, including in your phone. Many people depend on this technology to unlock（解锁）, open doors or pay for things quickly, but there is a problem: everyone is wearing masks（口罩）.
Now, the companies have improved the facial recognition technology. It can now work well even if people are wearing a mask.
A company in Beijing named Hanwang has announced that their product can correctly recognize（识别）95 percent of people wearing masks. What’s the secret?
A professor at an American University studies facial recognition technology. “As getting older”, he said, “our faces change shape.”
Facial recognition software is about more than just unlocking your phone. It’s about public safety. For example, you don’t need to show an ID card, which can be lost or stolen. It also means that diseases aren’t spread by touching things. It has become especially important now because of the COVID—19. It helps with safety and peace of mind.
More than that, facial recognition can be used to fight crime（犯罪活动）. It can notice crime and terrorists. The technology is used by police in places like government buildings
There is also a weakness of this technology: it fails when people wear both a mask and sunglasses. In this situation, all of the key facial information is lost.

【推荐2】I'm not a fast reader and I don't read as much as many other people, but reading is something I enjoy. It opens new worlds to me.
Recently I found Kobo, an online book store that allows me to buy e-books and read them on a device(设备) of my choice. I'm a girl living in Indonesia, where e-books are not available and I had to buy physical books (有形图书) from Amazon in the past. There are two problems with it:
Shipping cost. Since I live far away from the United States, it costs a lot to Ship a book.
Shipping costs almost as much as the book itself.
Shipping time. It takes about three weeks for the books to arrive through postal mail.
Now with Kobo, I can eliminate those two problems. Not only does it cost less time and money to get the books, but also I prefer to read e-books this way than reading physical books. Here are three reasons why:
●I can easily bring the books everywhere. Since all the books are in my iPod touch, I can simply put the device into my pocket and bring it everywhere I go.
●The size is smaller. The size of the iPod Touch is smaller than a physical book. This makes reading more convenient(方便) for me,
●I can read in any position I want. The iPod has a light source, so I can read when I am in darkness. This means that I can read in practically any position and condition.
One more advantage I haven't mentioned is space. Physical books take space, but e-books don't.
