Your school asked parents about the social development in children in the last Parents' Meeting. Here are some opinions. Read following information and answer the questions.

    The human brain remembers negative experiences more easily than positive ones. Our brains have developed this way because threats, like dangerous animals, had a more immediate effect on our ancestors' survival compared to positive things like food or shelter. As a result, you likely know what makes you unhappy, but do you know what makes you happy?

    Research suggests that our level of happiness depends partly on factors we cannot control—our genes and our life circumstances. But our level of happiness is also shaped by the choices we make. If you've been chasing wealth, fame, good looks, material things and power, you may be looking for happiness in all the wrong places. Psychologists suggest that the following habits make people happier.

    People who form close relationships tend to be happier than those who do not. The number of friends we have is not important. What matters is the quality of our relationships. Relationships that bring happiness usually involve the sharing of feelings, mutual respect, acceptance, trust and fun.

    People who exercise regularly improve both their physical and mental well being. Some research has shown that exercise can be as effective as medication in treating depression.

    When we are so interested in an activity we enjoy that we lose track of time, we are in a state of flow. The activity could be making art, playing piano, surfing, or playing a game. People who experience flow in their work or hobbies tend to be happier.

    People are more likely to be happy if they know what their strengths are and use them regularly, People who set goals and use their strengths to achieve them tend to be happier. People are especially happy when they can use their strengths to serve the greater good.

    People who think positively by being grateful, mindful and optimistic are more likely to be happy. Being grateful means being thankful, Bejing mindful means being open to, focusing on and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

    Can dogs and cats get along well in the same home? People who are thinking about getting a dog as a friend for their cat are worried that they will fight. A recent research has found that if the cat is taken back home before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. In two-thirds of the homes cats and dogs have a good relationship.

    However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression(侵略，好斗) and fighting were found in 10% of the homes. One reason for this is probably that some of their body languages are just different. For example, when a cat turns its head away it means aggression, while a dog doing the same means submission(顺从).

    In homes with cats and dogs living peacefully, researchers found a surprising behavior. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk "Dog", and dogs can learn how to talk "Cat".

    What's interesting is that both cats and dogs have appeared to become smarter. They can learn to read each other's body languages, suggesting that the two may have more in common than was expected. Once familiar with each other's body language, cats and dogs can play together, and enjoy sleeping together on the sofa.

    The importance of this research on cats and dogs may go beyond pets — to people who don't get along well, including neighbors, colleagues at work, and even countries. If cats and dogs can learn to get along, surely people have a good chance.

    Forests are always losers at the Olympics, and that's unlikely to change anytime soon.

    For the winter games in PyeongChang, South Korea, virgin forest was destroyed on Mount Gariwang to accommodate ski runs. For the 2022 Winter Olympics in Beijing, a ski run is set to wipe out part of the Songshan National Nature Reserve And let's not forget the 240 acres of Atlantic Forest that were leveled for the 2016 games in Rio de Janeiro to make way for a golf course.

    For the upcoming Tokyo games, environmental and human rights advocates have been raising alarms about the use of tropical wood to build the New National Stadium. Activists have fought against such environmental destruction. The damage is often permanent, threatens endangered plants and animals and, in some cases, causes conflicts with native people But frequently the country's organizing committee, and the International Olympic Committee (IOC) have found ways to make it reasonable—despite a paragraph in the Olympic Charter that states that the IOC's role is to "encourage and support a responsible concern for environmental issues."

    As it stands now. the IOC has little authority over a city's local organizing committee, which finally plans the event, Chappelet, professor of public management at the University of Lausanne, told Earther. "Even if the IOC is dissatisfied with the way host cities have prepared for the games, they have no built-in systems to supervise (监督) them so that they strictly follow the Olympic Charter. The only thing they can do if they're not happy is to withdraw the right to organize the game. But the IOC could include more enforcement (执行) systems into the contract (合同) they make with the host city, he added. That contract must be signed and obeyed by everyone. Those who break it could be fined.

    Boykoff, the author of several books on the Olympics, suggested a similar solution. "The IOC could insist that host cities prioritize their ecological promises, but instead they look the other way, time and time again," he said.

    If you are ever in Connecticut, you need to be sure to take the family to Lake Compounce Theme Park. The park lies in Bristol, Connecticut. It has been opened since 1846 and is known as America's oldest park.

    In October, they open the park for an event called Haunted Graveyard which is open at night. The rates are $ 34.99 for regular tickets, $ 25.99 for kids and $17.99 for those over the age of 60. If you go before 5: 00 p. m., you only pay $17.99.Kids under the age of three are free and parking is $8.00.

    The rides at the theme park are so much fun. The ride liked by all is the Boomerang with the top speed of over 45 miles per hour. The drop on this ride is 125 feet. Another popular ride is the Pirate Ship. These two rides are great for thrill seekers because you actually feel as if you were falling out of your seat.

    The park also has plenty of water rides for those who love water fun, such as water guns and water slides. Lights Out is a fast water slide that is all in the dark. It goes around what looks like a lighthouse. Besides the rides, the park also has fun shows for the whole family. They have a great show and a cool circus. There are also some great places to eat at the park.

    You can stop at the entrance to get a map first. You won't be able to visit the whole park in a day so you should have your family choose what you want to and have fun!

    Doctors say you had better use it before you lose it. The more you sit each day, the more chance you have of getting sick.

    Richard Rosenkranz of Kansas State University was among the researchers. He said people who sat for long periods were at great risk of diseases when compared with those who sat less. He said that was especially true for some chronic (慢性的) diseases.

    Richard Rosenkranz studied the relationship between sitting and chronic diseases in middle-aged Australian men. He worked with researchers from the University of Western Sydney. They examined the health records of more than 63,000 men from New South Wales. The men were between the ages of 45 and 65. The men reported about what diseases they had, or did not have. And they kept record of the amount of time each day that they sat.

    The study also showed that exercising every morning for 30minutes did not reduce the health risk if you spend the next eight hours sitting at the desk. Mr. Rosenkranz said it was important to make sure you exercise. But he said it was also important to find ways not to sit so much during the day.

    Many jobs today require sitting and working at the desk all day. James Levine works at the Mayo Clinic in the United Sates. He suggests working while standing at high table some of the time instead of sitting at a desk. Dr. Levine also suggests standing while using the telephone or eating. Or he advises walking with the people you work with for an on-foot meeting. And he notes that if you spend more time on your feet, you may have muscle activity that helps burn fats and sugars in your body.
