江西省九江市永修县第三中学2023-2024学年九年级下学期第一次质量检测英语试卷试题详情
请阅读下面短文，根据短文内容从每小题所给的A、B、C、D 四个选项中选出最佳选项。
Traditionally, we take the subway with our subway cards or by scanning QR codes（扫描二维码）on our smartphones. But now, people traveling on the Beijing Daxing Airport Express subway have a new way to take a ride: They can scan their palms.
To enjoy the service, people need to register their palm prints on machines in subway stations along the Daxing Airport Express subway line. Then they have to activate（激活）the palm﹣scanning function on their smartphones. Once they do this, they can scan their palms at ticket gates to pass through. After they finish the travel, the payment service on their smartphones will pay the money for their ride.
Many people welcome the new technology. They think it helps them to travel faster and more easily. They don't have to take out their subway cards or smartphones when they want to pass through the ticket gates. And they no longer have to worry when they forget to take their subway cards or when their smartphones run out of battery. What's more, the palm﹣scanning technology is very friendly to old people and those who have special needs. Those people may not use smartphones well. This technology makes it possible for them to take the subway without using smartphones.
In addition to Beijing, the palm﹣scanning technology is also in service in the subway station of Shenzhen.
And there are hopes that it can be used in more places like stores and restaurants in the future. （1）How can a passenger take the subway with the new system？
A. By swiping a subway card. B. By scanning a QR code.
C. By showing his ID card. D. By scanning his palm.
