Dogs can tell how other dogs are feeling from the way their tails are wagging (摇摆), according to researchers who monitored the animals’ heart rate as they watched dogs’ movies. The Italian team found that dogs had higher heart rates and became more anxious when they saw others wag their tails more to the left, but not when they wagged more to the right, or failed to wag at all.
The curious form of communication is probably not intentional, or consciously understood, but is instead an automatic behavior that arises from the structure of the brain, said Giorgio. “It’s not something they clearly and exactly understand,” Giorgio told The Guardian. “It’s just something that happens to them.”
Giorgio traces the effect back to the way the two halves of the brain process different experiences. In a previous study, his team showed that when a dog had a positive experience, activity rose in the left side of the brain, bringing about more tail wagging to the right. Or else more tail wagging to the left. The effect is barely visible to the human eye because dogs tend to wag their tails too fast, but it can be seen with slow motion video, or in some larger types.
In the latest study, the researchers wanted to find out whether the direction of tail wagging had any effect on other dogs. To get an answer, they fitted dogs with vests that recorded their heart rates, and played them movies of other dogs wagging their tails one way and then the other. To ensure the dogs reacted only to tail wagging, and not appearance, they repeated the experiment with dogs that appeared only as shadows.
“When dogs saw other dogs wagging their tails to the right, there was quite a relaxed reaction and no evidence of an increased heart rate. But when the wagging was to the left we saw an increase in heart rate and a series of behaviors typically associated with stress, anxiety and being more watchful,” Giorgio said. The anxious animals held their ears up, breathed, and kept their eyes wide open. The study appears in the latest issue of Current Biology.

Some of my fondest memories with my family are from when I was in middle school， when the three of us enjoyed trips that I remember vividly to this day. But during my younger days， like 4 or 5 years old， we vacationed in places like Cancun， Jamaica and Hawaii and I can't tell whether I actually recall those memories or whether I'm filling in the gaps through photo albums.
A frequent discussion I have with my coworkers and friends，' who are also in their 20s， is how we wish our parents had taken us on more vacations when we were much older. What I suggest is to hold off on those grand vacations until your kid is about 12， when they can begin to understand what a privilege is， and you can save the international travel until they're in high school. Of course， I do understand that sometimes， it's not the kids but the parents who just want to enjoy a vacation. But in other cases， when the main goal is to create family memories， you can still accomplish that in other ways.
It wasn't until college that I realized how important travel is， and I can't tell you how many times I've thought about wanting to redo those family trips now. Especially during a time in my life when an international trip is outside of my budget， I think about how much money my parents spent on our vacations that ended up being a complete blur.
I'm not telling you to deprive （剥夺） your children of fun family memories， either. I'm simply arguing that you should travel locally or within your state. Although your little ones might not care about the destination， they will remember that you are all together and have a great time. That's the most important thing， anyway.

When Joshua Coombes got off the bus in Washington, D.C., on this past February, he didn’t set off for the usual tourist attractions along the National Mall. Instead, the London-based hairdresser (理发师) headed for the marble fountain where homeless people gather outside. Most travellers walk by without a second glance. So what Coombes did next may well have surprised them: He chatted with them, pulled out his scissors and gave them haircuts, free of charge.
Whether in London, New York or Washington, D.C., homelessness can seem like a problem too huge and difficult to deal with. But Coombes realised that he didn’t have to solve all of everyone’s problems to make an impact. Sometimes, a small luxury such as a haircut can go a long way in boosting someone’s dignity, he told The Washington Post.
Two years ago, he founded the campaign Do Something For Nothing. His mission: to make a positive impact by giving haircuts to homeless people he meets on city streets, connecting with them on a human level and sharing their stories on social media. So far he has cut the hair of hundreds of homeless people, including a few women.
For Coombes, the campaign is about the importance of human connections. He wants to bring people together, regardless of what their relations are, and he sees the simple act of conversation as a step toward strengthening ties between people. In an age when virtual interactions can replace a real sense of community, Coombes finds haircuts to be a simple but important way to connect with people physically and emotionally.
Coombes’s world travels are partially funded through companies and NGOs that commission him to speak about his campaign. As he devotes more time to it, he has steadily decreased the hours he spends in the salon at home. His most recent trip to the US was sponsored by Leesa Sleeps, a Virginia-based mattress company. He will leave for Barcelona soon and plans to return to the US in the next few months.

A.The homeless people. B.The tour guides.

2.What is the purpose of Coombes’s founding the campaign?
A.To make the homeless people more beautiful.
B.To increase the connections with homeless people.
C.To bring the homeless people together to the shelters.
D.To help the homeless people change the real sense of community.
3.What do we know about Coombes?
A.He dislikes usual tourist attractions.
B.He travels around the world with his own expenses.
C.He thinks people can take action to positively affect others’ life.
D.He goes away from home in order to travel around the country.
4.What is the main idea of the text?
A.A hairdresser travels with homeless people.
B.Homeless people are connecting together.
C.Companies work together to help homeless people.

One day on my way to home, I saw a boy hit by a motorcycle. I rushed to him rescue immediately. I lifted him gentle in my arms, stop a car and sent him to a nearby hospital. Know he only suffered minor injuries, I smiled in relief. This evening I got home very late, and my heart was full of joy and peace. Not until then did I understand meaning of the proverb: “Helping others are the source of happiness.” This may be one of the most unforgettable memory of my life.
