1 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

9 . Have you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating(冬眠) .It’s too bad that humans can’t hibernate. In fact, as a species, we almost did.
Apparently, at times in the past , peasants in France liked a semi-state of human hibernation . So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold people all over France shut themselves away and practiced the forgotten art of doing nothing at all for months on end.
In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed fundamentally since the invention of artificial(人造的) lighting and the electric bulb.
When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though.   Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’ uninterrupted sleep is a modern invention.
In the past , without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight. The late night period was known as ”The Watch” It was when people actually kept watch against wild animals ,although many of them simply moved around or visited family and neighbours .
According to some sleep researchers, a short period of insomnia(失眠) at midnight is not a disorder .It is normal . Humans can experience another state of consciousness   around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning .This period can be an extraordinarily creative time for some people .The impressive inventor, Thomas Edison , used this state to hit upon many of his new ideas.
Playing with your sleep rhythms can be adventurous   ,as anxiety may set in. Medical science doesn’t help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural ; however, according to Warren’s theory，it is really the opposite of what we need.
