It is easy to overlook the role that your body plays in influencing your mood(情绪). When you are 49 , you may find yourself blaming work pressures or an unknown future. However, it could just be that you’ve been sitting behind your desk too long.
One way to improve your mood is 50 . Psychologically, it provides you with a break from the stresses in your life. Also, in the process, you may aim for  51  goals, like a new personal running record or a better body shape. The achievement of a particular goal makes you feel good and contributes to your 52 . That is why exercise has been shown to 53 your self-respect.
You do not have to train yourself 54  to feel the psychological benefits of exercise. What really matters is 55 , not intensity(强度) of your exercise. You can try walking for 30 minutes five times per week or simply gardening on weekends.

Along the rivet banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken，eats green 1eaves has the stomach of a cow and has claws(爪)on its wings when young. They build their homes about 4.6m above the river，an important feature(特征)for the safety of the young．It is called the hoatzin．
In appearance，the birds of both sexes look very much alike with brown on the back and cream and red on the underside．The head is small，with a large set of feathers on the top，bright
eyes, and blue skin．Its nearest relatives are the common birds cuckoos．Its most striking feature，though，is only found in the young．
Baby hoatzins have a claw on the 1eading edge of each wing and another at the end of each wing tip．Using these four claws, together with the beak(喙)，they can climb about in the bushes,
looking very much like primitive birds must have done．When the young hoatzins have 1earned to fly，they lose their claws．
During the drier months between December and  March hoatzins fly about the forest in groups of 20 to 30 birds，but in April，when the rainy season begins，they collect together in smaller living units of two to seven birds for producing purposes.

For jet-setters, a new way to get a restful night
Many people hate the idea of having to sleep on a plane. But Swedish entrepreneur Oscar Dios thinks they can be persuaded otherwise and he has created a new kind of hotel to prove it.
Dios says it is the world’s first jumbo jet hostel, an actual jet-plane at’ Sweden’s main airport outside Stockholm which has been converted into a 25-robin guesthouse that sleeps as many as 72 people.
“I learned abo0t this plane that was-standing abandoned at Arlanda airport and I’ve been trying the concept of hostels in many different houses and buildings,” he told reporters. “I thought, ‘Why not a plane?’”
Jumbo Hostels opened for business on Thursday, giving customers the chance to check in and sleep in a room that can best be described as cozy.
“The most challenging part with this project is trying to build something inside a metal hull -- it’s just really, really tight.”
The jet, which was originally produced for Singapore Airlines, was taken out of service in 2002.
One thing the hostel has. going for it is price-a room starts al 35.0 Swedish crowns (about $4.1% which is a lot less than hotel rooms outside of major airports.
Another feature: customers can get married on the wing of the plane and reside in the plane’s more luxurious honeymoon room situated in the cockpit.
Instead of walking down the aisle, lovebirds can take what Jumbo Hotel calls the “wing walk,” where they can be joined in bliss at the wing tip. The hostel has someone ready to perform the ceremony.
But in some respects, this hostel remains a plane-most clients have to share the jet’s nine  bathrooms and staff only wear air steward and stewardess outfits. The only room that has its own bathroom is the honeymoon suite.
