题目

物联网连接的是物理世界和（ ）。 A . 现实世界 B . 虚拟世界 C . 信息世界 D . 人类世界 答案：CThese days shared bikes are becoming more and more popular in many cities. In my WeChat friend circle, many of my friends are sharing photos of themselves riding bikes, especially during the weekend in natural parks. I'm very happy that there are shared bikes on the road. They have saved us a lot of time during special situations, and on beautiful, clear days, people enjoy riding them outside the city. I tried shared bikes last week, and I didn't like it very much. I think shared bikes without baskets, are for sportsmen. They are hard to ride, and the seats are not comfortable. It makes me wonder whether people really like riding shared bikes or are just saying this to agree with others. A friend secretly told me she tried the bikes to take exercise. She doesn't like bikes and finds Beijing's roads too hard for bike riding. But these days, the only way to hang out with her friends is riding out of town together. To join them, she had to pick up bike riding again. Another friend told me that he started talking about and sharing photos on shared bikes just to appear modern and fashionable(时尚的) to friends. He started paying attention when shared bikes were first used. These views(看法) will give me something new to think about when I ride these bikes again.1.What does the writer think of shared bikes?A.
