Do you find yourself tired all the time although you get enough sleep Then maybe this is for you. When you’re feeling weak and tired, the worst thing to do is to take a short sleep.

Do you stay in the same small area without getting up to move around Does your job require that you sit down the whole day in front of a computer Any of all of these reasons might be the cause of your energy loss, keeping your energy level low.

{{B}}North Pole Explorations{{/B}}
If Santa Claus really does reside at the North Pole, he must live a lonely life. The North Pole isn’t what most of us would consider a hospitable place as the average winter temperature there is 40 degrees below zero Fahrenheit (华氏温度) (-40 Celsius). And while Santa’s reindeer are considered Arctic animals, not much life actually calls the North Pole its permanent home.
For adventurers, the North Pole is comparable to outer space: an unknown frontier that’s ripe for exploration--and exploitation. The region doesn’t belong to any one country, so there are always disputes about who can lay claim to the untapped natural resources there. And although the prospect of melting ice around the North Pole isn’t pleasant from a global warming standpoint, it could make those resources easier to reach.

Passage Five
First, the spotted owl was threatened by logging in the Pacific Northwest. Now it’s in danger from a new enemy, the barred owl. Barred owls have been moving to the Northwest from the eastern part of the United States. Stan Sovern has studied spotted owls. Now when he calls for spotted owls, barred owls are starting to appear. Sovern threw a mouse on the ground, and a barred owl grabbed it.

Professor Ned K. Brown of the University of California-Berkeley says, "In some areas of Washington, the barred owls moved into very dense, deep woods. The same kind of woods that are opened up, or destroyed by logging, that adversely influences the spotted owls."
