In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame (驯化的) fox population. Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk, in Russia, he sought to find the evolutionary pathway of tame animals. His test subjects were silver-black foxes, a melanistic (带黑色的) version of the red fox that had been bred in farms for the color of their fur.
He selected the animals based on how they responded when their cage was opened. About 10% of the foxes displayed a weak “wild-response”, meaning they were docile around humans. Those that hid in the corner or made aggressive voices were left in the farm. Of those friendly foxes, 100 females and 30 males were chosen as the first generations of parents.
When the young foxes were born, the researchers hand-fed them. They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. If the young foxes continued to show aggressive response, even after significant human contact, they were thrown away from the population—meaning they were made into fur coats. In each selection, less than 10% of tame individuals were used as parents of the next generation.
By the fourth generation, the scientists started to see dramatic changes. The young foxes were beginning to behave more like dogs. They wagged their tails and “eagerly” sought contact with humans. By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could “read” human hints and respond correctly to gestures or glances.

Many teens in high school want to try out for sports. A lot of them try out because they think it will make them popular or get them more dates. While this may seem like a silly reason, there are lots of other benefits to sports that your children may fail to notice.
With TV, movies, computers and video games becoming more and more popular, it has become so much easier for teens to be by themselves rather than going out with friends. Kids used to go hang out at the mall or drive around town; now they just sit at home. Getting your teens into a sport gives them a chance to go out and spend time with other people socially. While they may not find a new best friend, they will learn how to communicate with one another and work as a team and they’ll find something useful later in life.
More and more kids are becoming overweight. Joining a team sport will help teens get out and get some exercise without feeling pressured to lose weight or get in shape. What’s more, if your teens see that their physical condition is causing them to under-perform, they may be encouraged to do other activities to get healthy. By the time your children reach their teenager year, part of good parenting will be providing them with direction and encouragement and continuing to help them develop a healthy style of living.
These days, it’s becoming harder to show your teenagers that you love and support them. A great way to do this is by showing up to their game, helping them practice, and helping with team fundraisers. These are also great ways to spend time with your kids and talk to them.
You may think “but my teen isn’t good enough to make their school team”. There are plenty of other places besides school to play team sports. You can always check out “for-fun” teams. You could look into more unknown sports that you may not have thought of, did you know that bowling is a NCAA team sports If you do a little research, you’re sure to find something your teen will enjoy.
Team sports are a great way for teens to get out of the house, get moving, make friends, and even get a scholarship to college. So why not talk to them about getting into sports today

Have you ever had a headache during a test? Have you ever been too worried about something that you have a headache or even can’t sleep at night? If so, then you know that stress is.
Not all stress is bad for you. Some kinds of stress can help you get things do better, like when you are running towards the finishing line or when you are being asked to give a speech to your class. Stress sometimes can help push you to make full preparation for a test. However, too much stress can result in anger, depression and other related problems, which we need to take serious.
There are many things in our life what might cause stress ------ having too much homework, taking a difficult test, and having economic problems.
It’s impossible to live in a life completely free of stress, so you should learn to deal with stress. The best way reduce stress is to have a balance life. If you get enough sleep, eat properly, take more exercise and have enough fun time, you’ll probably feel less stressed.
I remember the occasion when mother sent me to the main road, about twenty yards away from our house, to invite a passing group of seasonal work-seekers for a meal. She1.(instruct) me to take a basket along and collect dry cow dung(牛粪) for making a fire. I was then to prepare the meal for the group of work-seekers.
2. thought of making an open fire outside at midday,and3.(cook)in a large three-legged pot in that intense heat, was sufficient to upset even an angel. I did not manage to hide my feelings from my mother and, after serving the group, she called me to the veranda(走廊)4. she usually sat to attend to her sewing and knitting.
5. straight into my eyes, she asked “Why did you get angry6. I requested you to prepare a meal for those poor people?”7. my attempt to deny her blame,using the heat of the fire and the sun as an excuse for my rude behavior, mother, she gave me a firm look,8.(say), “You cannot detect what trouble may lie ahead of you.”
I9. (sudden) realized that if I had refused to offer this group of people a meal,10. would be impossible that in my travels some time in the future,I would get these individuals' help.
