Forget your password? Well, you'll never forget your face. Using your face is quicker and (convenient) than using your password. You could take the subway or board a flight with just your face alone. This is facial recognition(人脸识别)works.

, like all new technologies, facial recognition technology can be used for good or for bad. There are now no laws to regulate (规范 ) the collection and use of facial information, according to famous researcher at China University of Political

★Imagine taking a flying taxi to the airport, or jumping over crowded city streets at rush hour, getting where you want to go far faster than you could in a car. Believe it or not, you might be able to do these things in an air taxi sooner than you think.
An air taxi is something like a helicopter that can carry people from place to place. Air taxis don't need a long runway like planes do. They can go straight up and down.
In June, the government of America agreed to allow a company to start testing their new air taxi. This is the first time they' ve tested a taxi that's been built in a factory. Before that, all their taxis were made by hand.
By 2025, the company hopes to start carrying passengers for money. They' ve teamed up with Delta Air Lines to create a program to fly people from their homes four other passengers. They can go around 100 miles before the electric batteries need to be recharged.
Compared with helicopters, the director of the company says their air taxis are both quieter and cheaper. The company expects to charge about $3 a mile at first. But over time, they hope to bring the price down to less than $1 a mile.
And as exciting as the idea of flying taxis is, some people are still concerned about them. The air taxis may be quieter than helicopters, but they' ll still be adding noise and traffic to our skies. Some people worry that only rich people will be able to afford to use them.
It seems likely that air taxis will be part of the future of travel. But there's still a lot to do before air taxis become common.
(1)、How does the writer begin the passage?A、By asking a question. B、By imagining a scene. C、By presenting a picture. D、By making a comparison.(2)、What are the main features of the air taxi?A、Traditional and expensive. B、Convenient and inexpensive. C、Advanced but space-taking. D、Safe but energy-consuming.(3)、Which of the following is TRUE about the new air taxi?A、It's made by hand. B、It can fly 100 miles per hour. C、It looks like a helicopter. D、It can carry four people in all.(4)、What is Paragraph 6 mainly about?A、The concerns about the new air taxi. B、The noise created by the new air taxi. C、The traffic rules to be made soon. D、The high price of taking the new air taxi. -

If you look around the room you are in right now, you'll probably notice a number of electronics. But can you imagine if they all had to be joined together by wires(电线) ? Picture the wire snaking along the floor, for example, from your smartphone to your speaker, or connecting your game controller to the computer screen, meaning you could never sit more than a couple of meters away from it. A world of electronics connected by wires wouldn't just be untidy, but a possible danger, too. That's where Bluetooth comes in. We've all heard of it—but what exactly is it?
Bluetooth is a method of short-distance ( 短 距 离 的 ) wireless communication between electronics that makes use of the power of radio waves. The idea was first thought of by Dr. Jaap Haartsen at a Swedish mobile company in 1994. Things really stepped up in September 1998 when the Bluetooth Special Interest Group(SIG)was set up to develop and spread the technology. Bluetooth 1. 0 came out in 1999, and a year later it began to be used in mobile phones and desktop computers. Now Bluetooth has become an increasingly popular way of solving the problem of more and more electronics needing to be connected, without having to connect everything together with wires.
But if you look at the remote control(遥控器)you use to choose the program on TV, you might rightly ask yourself why Bluetooth was such a big deal. After all, connecting objects with infrared signals(红外信号)which can't be seen had been done before. The problem with remote controls is that they need to keep what is called "line of sight" . If something is standing between the remote control and the receiver, it won't work. Because Bluetooth uses radio waves, the things standing in the way are no longer a problem.
Since its creation in the late 1990s, the technology has become more and more improved and widely used, with the 4 billionth Bluetooth object shipped in 2020.
(1)、How does the writer lead in the topic "Bluetooth" in Paragraph 1?A、By describing scenes. B、By comparing facts. C、By telling stories. D、By explaining reasons.(2)、With the setting up of SIG, Bluetooth ____.A、started to be used in cars B、made radio waves known to people C、improved and spread quickly D、was able to connect all electronics(3)、From Paragraph 3, we mainly get to know the ____ of Bluetooth.A、development B、popularity C、background D、advantage(4)、Who will most probably be interested in this text?A、Phone sellers. B、Technology fans. C、Newspaper reporters. D、History lovers. -
