任务四：任务型阅读（10分）
Today, QR codes are everywhere in our lives. However, scanning (扫描) them a lot might sometimes feel like a burden (负担). Is scanning QR codes for everything really convenient? What do you think?
Some people think using QR codes is convenient for us. We can scan a QR code to get on the bus without using cash. When you're at a store, you just need to show the QR code on your phone. Then you can pay for your toys or snacks. You don't need to worry about getting the numbers wrong. Also QR codes help us get lots of information, and it's all fast and right. For example, in the zoo, there are QR codes everywhere. Scan them and you can learn all kinds of amazing facts about animals, like having a personal tour guide right on your phone.
But some people think scanning QR codes feels like a burden now in our everyday lives.
First, it takes more time. Back in the day, ordering food at a restaurant was simple—just talk to the
waiter! Now, you might need to take out your phone and scan a QR code to follow a restaurant or an official account (公众号). If there's no internet, you can't even do that. Also when you scan some QR codes, there might be pop-up (弹出的) ads. They may take you to some other pages. Or you need to share more of your information. Later, you may get calls and junk messages.
21. How can we get on the bus without using cash?
22. Back in the day, what was simple to do at a restaurant?
23. What can people learn by scanning the QR code of the zoo?
24. What may happen if you share your own information?
25. What do you think of using QR codes in your daily life? Why or why not?
