Here comes a story that many years ago a man arrived at a village in India to catch monkeys so he could sell them to zoos. The monkeys, however, were very clever and every sort of trap he set failed. A young boy watched the man's pathetic efforts and laughed.

    The man said, “If you can catch me a monkey, I'll give you $ 2.” That was a huge amount of money then.

    The boy went to his home and took a clay pot with a narrow neck. He placed a few nuts around the pot and put lots of nuts inside. He then tied the pot to a tree and told the man, “We should have a rest in a few hours. Let's wait in the village. The monkey will call us when he is ready.”

    Certainly enough, a band of monkeys soon discovered the nuts and the pot. One slipped his hand in the pot and grabbed a handful of nuts, but he couldn't pull his hand out of the narrow opening of the pot because his fist(拳头) was clenched. The monkey feared and started making loud noises. Some of the other monkeys tried unsuccessfully to pull the pot off his hand.

    The boy and the man heard the noises and the boy got a big strong bag. As they approached the monkeys they all ran away except the one with its hand in the pot. The boy grabbed the monkey and the pot. The man was amazed and asked the boy the secret of his monkey trap, “Why was it so easy for the monkey to get his hand in but so hard to get it out?”

    The boy laughed and said, “The monkey could have easily got his hand back out and escaped, but he would have had to let go of the nuts in the pot and he just wasn't willing to let go. They never are.”

    What lessons can be learned from this story? Do people sometimes trap themselves by holding onto things that they should let go? Do you?

    Jealousy is such a powerful emotion that at least one study has characterized it as the third leading cause of non-accidental homicide(杀人) in all cultures. In a recently published study, researchers experimented with dogs to see whether they, like humans, have the nature of jealousy.

In an experiment, the authors took 36 dogs—along with their owners—and observed the dogs' behavior as their masters interacted with three non-living objects. One object was a children's book, which they read aloud; another object was a plastic pumpkin lantern; and the third was a mechanical stuffed dog that gave out a bark when the owner pressed a button.

    Former studies concluded that babies were probably capable of jealousy. In the experiment, their mothers showed attention to a life-like doll instead of their child, and other objects. The babies were reportedly more likely to respond with “negative” behavior if their mother turned to pay her attention to the doll.

    In the dog experiment, authors instructed the dog owners to push the bark button on the stuffed dog's head, and then speak to it sweetly, while ignoring their own dog. After that, they showed attention to the pumpkin lantern, and read the children's book, while also ignoring their dog.

    It is interesting to see the dogs were far more likely to act aggressively when their owners spoke to the stuffed dog than when they paid attention to the other objects. One-fourth of the dogs snapped at the stuffed dog, while only one dog snapped at the lantern or the book. The dogs were also more likely to push or touch their owners as they interacted with the mechanical dogs, and tried to get in between the owner and the stuffed dog more frequently than the other objects.

    “One possibility is that jealousy developed in species of many young relying on the parents, the young compete for parental resources such as food, attention, care, and affection,” the authors wrote.

    How far would you go for your kids education? That's a question many parents are asking in the wake of the college cheating scandal(丑闻)involving 38 wealthy parents around the country, including actresses Lori Loughlin and Felicity Huffman. Here's how far I went. In the fall of 2017 my husband and I lost our jobs. We had to tell our daughter, Casey, that we couldn't afford to send her back to school for her junior year at Fordham University. We decided the best choice for our family would be for Casey to sit out a year. We promised that we would get her back the following year. Casey decided to spend the year volunteering in South Africa On Sept 30, 2017, we put our oldest child on a plane halfway around the world. Casey worked as a tutor teaching kids math, English and music in Johannesburg. We did get Casey back in school in time. When she returned to the campus, she studied harder. She isn't what she used to be. Each day is marked by gratitude because she knows what it is like not to be able to get an education.

    I wonder why the college cheating scandal happened and I think it boils down to this: Parents want to create a comfort zone for their kids. Of course, we want the best for our kids but sometimes we forget that real growth doesn't happen in times of comfort; those valuable lessons come when we are forced to think in ways we otherwise wouldn't have.

    While I did less for my child than these wealthy parents did in terms of means, in other ways I did more. I taught her that disappointment is a part of life and we should face it bravely rather than avoid it. My husband and I showed Casey that her strength is in her struggle. That's how far I went for my kid s education. And I dare say she is wiser and better off for it.

    Many people like traveling, but they cannot take their dogs wherever they go. Some people let their dogs stay alone at home while others ask someone else to take care of their pets. If you're leaving your beloved pet at home for a holiday, it can turn into a bad experience. Luckily, you don't have to worry about your dogs anymore because Rover can cover for you while you are on leave. Rover is the latest service to offer at home dog boarding. It's a good alternative (替代物) to boarding your dog at a dog boarding kennel (狗舍) or your neighbor's house.

    The way Rover works is sort of like Airbnb. Dog owners surf the Rover website or app for pet sitters (照看者), which can be organized by zip code (邮政编码) and available dates. Information of pet sitters is provided, complete with many reviews, specific services and rates. Now Rover has over 25,000 pet sitters in more than 5,000 US cities. And they're all experienced pet sitters.

    After finding someone that meets your needs, just send messages to the pet sitter to arrange a meeting. Then, like Rover says, all that is left to do is relax! Rover's pet sitters are encouraged to send text and picture information throughout the day, and if there's a medical emergency, the site will send a vet (兽医). Besides, don't worry about a pet sitter who fails to help you, because someone else will soon take his or her place.

    Can you imagine a world without music? Studies show that public schools across the country are cutting back on music classes to save money. Even worse, some schools have never had music classes to begin with. But without them, students' academic (学术的) growth and spiritual health could suffer. In fact, music classes are necessary for all students in schools.

    Recent studies Brown University have shown that students who received music education classes were better in math and reading skills than those without music classes. Another study by The College Board found that students taking music and art classes got higher points. Students' academic success seems to depend on their taking part in music education.

    Music programs in public schools also help to add to a student's sense of pride and self-confidence. Teens today have too many learning tasks. Besides, they have family problems, self-confidence problems, relations hip troubles, and choices about smoke and alcohol (酒精). All of these can stop academic success, but music education can help. A study by The Texas Commission on Drug and Alcohol Abuse found that students who took part in school music programs were less likely to turn to smoke. Music programs encourage students to work together to produce an excellent performance.

    Music crosses language, class and culture. Music allows students from different countries to connect. For example, at a school talent show, a new Japanese student played a piano duet (二重奏) with an American classmate. Two students from different cultures worked as a team with self-confidence and common purpose through music.

    The gift of music is priceless. We need to be sure to have necessary music classes for all students. The world is losing its music, and putting music into schools is the first step to get it back.
