Back in 2001, Pen Hadow and I traveled to the North Pole. One morning we'd just taken down our tent and started skiing. Pen was in front, and I was following him. Suddenly I got a strange feeling that something was behind us. I stopped,looked back and saw a polar bear, walking towards us.
Pen and I planned to stay where we were, try and look big, and frighten it away. Pen had a shotgun that we'd bought in Russia. That was his job. My job was to take off my skis,hold the skis in the air, make lots of noise, and frighten away the bear. Pen raised the gun and fired into the air. However,it jammed and failed to work.
The bear was walking towards us. Pen tried again, but again it didn't work. Then he walked towards the bear, and I thought, "Wow, Pen's gone completely mad. He's going to get eaten. What should I do "
I thought maybe I could throw a ski at it or stab(刺）it with a ski pole or something. Suddenly, the bear stopped.
Pen stopped. Bang. The gun went off. There was a big cloud of smoke that I thought surprised Pen and me more than it surprised the bear. The animal looked up, looked down,turned around and walked off. Pen turned around and said,"Quick, get the camera and take a photograph," and that was when suddenly I felt really nervous. I couldn't even undo the zip on our bag.
That was the morning of the second day of this journey. We were out there for about two months-fifty-nine days,but we never saw another bear that close.

Humans have little difficulty recognizing one another. And we know that no two faces are exactly alike. Even identical twins have slightly different faces. Each human face is truly unique, and now we've invented machines that are able to recognize faces for numerous purposes.
Governments, employers and security and police services are increasingly using facial recognition technology. This allows them to quickly confirm an individual's identity. Systems are becoming so advanced that a wanted criminal can instantly be picked out of a crowd of thousands of people. All that's required is an image in a database to compare with the image of any number of people in a crowd. Ordinary people, too, are using facial recognition to unlock their phones, their computers and other devices.
Personal facial recognition protection has several benefits. It is instantaneous, and it relieves us of the need to memorize passwords. However, a device will require a password in the rare event that it doesn't, for whatever reason, recognize the user's face.
There are numerous concerns about the use of facial recognition. Primarily, the concern is that it threatens privacy. The installation of more and more cameras in public and private places is now part of everyday life. This means people can be observed and recognized wherever they go. Cameras may make public spaces safer, but keeping law-abiding(守法的) citizens under constant watch is disturbing to many.
In the age of the coronavirus and the widespread wearing of masks, facial recognition systems are having some difficulty. A mask covers many of the facial data points used by recognition software to confirm a person's identity. In response, facial recognition systems are being trained to use less facial data. That could affect how dependable it is as a method of identity detection.
8. What's the author's purpose of writing Paragraph 2
A. To further explain the importance of facial recognition.
B. To describe the powerful functions of facial recognition.
C. To list in detail various advantages of facial recognition.
D. To state the unique advanced features of facial recognition.
9. Why are some people worried about the cameras
A. The cameras may be occasionally out of order.
B. Too many cameras disturb people's daily life.
C. People's personal life might be exposed to others.
D. The cameras make law-abiding citizens feel stressful.
10. In what aspect will facial recognition systems be improved
A. Getting more accurate with less information.
B. Becoming faster with more facial data.
C. Protecting personal information if necessary.
D. Responding more quickly to unexpected events.
11.What is the text mainly about
A. The wide popularity of facial recognition.
B. The rapid development of facial recognition.
C. The benefits of facial recognition.
D. The introduction to facial recognition.
D
While most human identification technology companies choose to focus on facial recognition, one Chinese start-up claims to have developed a much more accurate identification system based on micro features of veins(静脉)within human hands.
Developed by MELUX, AirWave is an incredibly efficient identification system that is said to be a million times more accurate than facial recognition technology. There are only 80 to 280feature points on a face that artificial intelligence can assess when scanning an individual, but AirWave is able to scan more than a million micro-feature points in the palm(手掌)of the hand within 0.3 seconds, making it virtually impossible to cheat. A simple scan of the palm over a special sensor is all that's required to get an ultra-accurate identification in real time.
"The AirWave full-hand-vein technology, based on artificial intelligence, is capable of sensing millions of micro-feature characteristic points, from major veins to the smallest organs,with just a single wave of the hand, enabling users to remain in motion while being identified and authorized," Xie Qinglu, founder and chairman of MELUX, recently told China Daily.
"The major veins and the smallest organs under skin are individually unique, and they are at the five-micrometer level and even more complex than road systems in a big city," Xie added."The AirWave technology can identify one hand out of a billion accurately in less than three-tenths of a second."
Right now, China's cashless society relies on facial recognition, QR codes and password systems to authorize(投权)mobile payments.MELUX considers current approaches to be either exploitable by weberime experts, or unfriendly to senior citizens. Privacy concerns are also well-founded, especially where facial recognition is concerned, so AirWave is considered much more efficient and secure, easy to use by anyone, and less attacked.
Published in 2018, AirWave technology has been making waves in China over the past year, and is already being in several cafeterias and government public service areas in South China's Guangdong Province.
12. What do we know about the recognition system based on veins
A. It can make cheating almost impossible.
B. Most people choose to make use of it now.
C. It runs more quickly than facial recognition.
D. It is based on 280 feature points within the hand.
13. How many recognition systems are mentioned in the text
A. Five. B. Four. C. Three. D. Two.
14. What's the purpose of developing the vein recognition system
A. To make China step into cashless society.
B. To replace the out-of-date facial recognition.
C. To develop a more advanced recognition system.
D. To make people free from being cheated completely.
15.What is the best title of the text
A. Chinese Recognition Systems
B. Future Trend of Recognition Systems
C. Cashless Society: Recognition Systems
D. A New Recognition System Based on Veins

【答案】A
【解析】细节理解题。根据第二段中的”AirWave is able to scan more than a million micro-feature points in the palm(手掌) of the hand within 0.3 seconds, making it virtually impossible to cheat"可知,基于静脉的识别系统使得欺骗几乎不可能发生。选项中的"impossible""cheating"为词汇复现。
13. How many recognition systems are mentioned in the text
A. Five. B. Four. C. Three. D. Two.
【答案】B
【解析】细节理解题。根据第五段中"facial recognition, QR codes and password systems to authorize(授权)mobile payments”可知,有面部识别系统、二维码识别系统和密码识别系统,再加上静脉识别系统,总共四种。
14. What's the purpose of developing the vein recognition system
A. To make China step into cashless society.
B. To replace the out-of-date facial recognition.
C. To develop a more advanced recognition system.
D. To make people free from being cheated completely.
【答案】C
【解析】推理判断题。根据第五段中的”current approaches to be either exploitable by webcrime experts, or unfriendly to senior citizens"和"Privacy concerns are also well-founded ... AirWave is considered much more efficient and secure, easy to use by anyone, and less attacked"可知,MELUX 公司认为目前的可用的识别系统要么易被网络犯罪老手利用,要么对老年人不友好,而且用户还需担心隐私安全问题,AirWave被认为是更高效、更安全,任何人都容易使用,不易被攻击的;由此可推知,开发静脉识别系统的目的就是为了研发更先进的识别系统。
15.What is the best title of the text
A. Chinese Recognition Systems
B. Future Trend of Recognition Systems
C. Cashless Society: Recognition Systems
D. A New Recognition System Based on Veins
【答案】D
【解析】主旨大意题。第一段引出静脉识别技术,第二、三、四段介绍了这种技术的工作原理及使用方式,第五段讲了开发这种技术的原因,最后一段说这种技术已经在广东有所应用了。文章主要介绍了一家中国初创公司开发的基于微观特征的更精确的识别系统—静脉识别系统,故D项”基于静脉的新识别系统”为最佳标题。
