We have noticed our life becoming a little easier these days. Now, when you go to a certain shopping mall, you can enjoy its free WiFi there. When you want to take a taxi, you can book one with your phone. In fact, all these can be seen as the basic parts of a smart city.

The idea of a smart city was brought up by US company IBM in 2010.Gernally, a smart city is a city that uses digital(数字的) technologies such as the Internet to improve city planning, save money and resources, and make our life convenient. How smart can a city be? Here are great examples that we can learn from.

In 2009, Dubuque became the first smart city in the US. The city used smart water meters to take the place of traditional water meters. They can examine water waste and leakage(泄露) and send data to let the house owner know. The same system is used for other city resources like electricity and natural gas. This way, people know how they use their resources and are glad to help reduce waste.

Santander in Spain also gives us a look at the future. If people point a phone toward a nearby bus stop, the phone quickly shows all bus lines that serve the stop as well as their arrival times. The government organized a research team and provided an App that collects data on almost everything: light, temperature, and the movements of cars and people. Opening the APP near a supermarket provides immediate information on special offers.

My name is Jack. I’m a Chinese student living in the United States. When my family moved to America in 2016 from a small village in Guangdong, China, we brought not only our bags, but also our village rules and culture. One of the rules is that young people should respect(尊敬) the elderly. Unluckily, this rule led to my very first embarrassment(窘迫) in the United States.

I had a part-time job as a waiter in a Chinese restaurant. At one time, when I was serving food to an old couple(夫妇), the wife asked me how I could serve the food so quickly. I told her that I tried to get their food quickly because I respected the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and told me about how sensitive Americans are and how they dislike the description “old”. I then walked back to the table and said sorry to the wife. After the couple heard my reason, they understood that cultural differences caused the problem, so they laughed and were no longer angry.

In my village in China, people are proud of being old. Not so many people live to their seventies or eighties, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.

However, in the United States, people think “growing old” is a problem since “old” shows that a person is too weak to work or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises, and women put on makeup, hoping to look young. When I told the couple in the restaurant that respected the elderly, they got angry because this caused them to feel they were not able to stay young. I told them something they didn’t want to hear.

After that, I changed the way I had been with older people. It is not that I don’t respect them any more, I still respect them, but now I don’t show my feelings through words.

3.The word “sensitive” in Paragraph 2 probably means “________ ”.

4.What is the main purpose of the passage?
