五、(2025·常州期末改编)阅读理解。〔人与社会——人际交往〕
In small villages, people often say hello to their neighbours in stores, on the streets, or outside their homes. But in cities, many people don’t greet their neighbours, even when they are standing in line at a supermarket. A recent study shows that greeting neighbours, especially up to six people a day, is really good for you.
The study has found that greeting others can make you happier. The magic number is six. When you greet up to six people, your happiness score goes up. After that, the score shows no further rise. The study got replies from more than 4,000 people. It tested people’s social happiness, physical happiness, community happiness and more. People who greeted six neighbours had a much higher happiness score than those who didn’t greet anyone.
You might think that saying hello is only about social happiness, but that’s not true. Regular(经常的) greetings also improve your physical and community happiness. That’s because all of these are joined together. If you feel your community is safe, it’s more possible for you to talk to people. Walking around your neighbourhood can make you feel better physically.
Dan Witters, the leader of the study, said, “We don’t mean that you should know the person well. Just stop and talk to them. The more people you greet, the more chances you have to start a conversation.”
Remember, saying hello regularly is a good way to improve your own happiness.
