And guess what？ It's fun! You don't have to give up the foods you love or do regular exercises. It's about balancing calories(平衡卡路里) in tiny ways that add up to big benefits (好处). You just use some tricks the "naturally thin" people do. Pick the ones you like, stick with them, and you'll lose weight and be strong!

Researchers from Yale and the University of Connecticut followed 600 middle-schoolstudents as they developed from fifth to seventh grade, nothing their weight and if they had zerobreakfast, breakfast either at home or at school, or breakfast in both places. They found thatweight gain among second-breakfast eaters was no different from the average gain seen amongall students.

It should be noted that only about one in ten children inthe study ate two breakfasts.

For reasons of safety and ease of maintenance, Washington and dozens of other communities are building rubber sidewalks made 76 ground-up tires of cars and bikes. The rubber squares are up to three times more expensive than concrete squares but 77 longer, because tree roots and freezing weather won't crack them. That, 78 , could reduce the number of slip-and-fall complaints made 79 uneven pavements. The shock absorbing surface also happens to be easier on the joints of slow runners and more forgiving when someone slips or falls, and the rubber sidewalks are considered more environmentally friendly.

Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals. The camel can lose up to 30 percent of its body weight as water without harm to itself, whereas human beings die after losing only 12 to 13 percent of their body weight. An equally important adaptation is the ability to replenish (Sheik) this water loss at one drink. Desert animals can drink huge volumes in a short time, and camels have been known to imbibe (吸收) over 100 liters in a few minutes. A very dehydrated person, on the other hand, cannot drink enough water to rehydrate at one session, because the human stomach is not sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication. The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain food from grazing sparse pastures. Desert-adapted mammals have the further ability to feed normally when extremely dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst.
What is the passage mainly about？
A．Animals developed different strategies to survive.
B．Large animals can take strategies to reduce the effect of extreme heat.
C．Animals can tolerate the loss of body water.
D．A very dehydrated person can drink enough water to rehydrate.
