Article: At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot. There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can't fly into the air from the ground. Their wings don't produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can't run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight. During the hours when most enemies are active, bats gather where few animals would think to look and most can't reach. This allows them to disappear from the world until night comes again. There's also little competition for these resting spots, as other flying animals don't have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract several muscles in your arm, which are connected to your fingers by tendons ;as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat's talons close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn't have to do anything to hang upside down.

Article: Give people a chance before you judge them because you really never know what's going on beneath the surface. I am always reminded that judging a person by what others say or my first impression is usually wrong. It's so easy to make assumptions and expectations about someone, just to find out they were completely false. The shy girl turns out to be one of the funniest girls I've ever met; the mean girl is actually very sensitive and loving; the _ guy is unsure of himself, etc. I hope there is a world where we stop judging a person by what they wear, their hairstyle, their job, their car; we simply love and accept them for who they are. Someone may have untidy hair because they over slept, or their clothes don't match because their house burned down and lost everything. All I'm saying is, "can we focus more on what's going on inside a person rather than the outside?" There are so many people who seem like everything is just fine on the outside, but the inside is angry or hurting. They don't know how to just be themselves or they're afraid to because they may be seen as the "crazy" or "strange" persons. I truly believe everything begins with ourselves. Before we can really stop judging others by the outside, we must stop judging ourselves. We must know how to treat ourselves first. Let's stop getting in our own way and accept ourselves and others as we are.

answer:
When we judge a person, we should pay more attention to _ .

Article: Would you like to be a king or queen? To have people waiting on you hand and foot? Many Americans experience this royal treatment every day. How? By being customers. The American idea of customer service is to make each customer the center of attention. Need proof? Just listen to the commercials. Most of them sound like the McDonald's ad: "We do it all for you." Actually, not all stores in America roll out the red carpet for their customers. But wherever you go, good customer service means making customers feel special. People going shopping in America can expect to be treated with respect from the very beginning. Most places don't have a "furniture street" or a "computer road" which allow you to compare prices easily. Instead, people often "let their fingers do the walking" through the store hot lines. From the first "hello", customers receive a satisfying response to their questions. This initial contact can help them decide where to shop. When customers get to the store, they are treated as honored guests. Customers don't usually find store clerks sitting around watching TV or playing cards. Instead, the clerks greet them warmly and offer to help them find what they want. In most stores, the clear signs that label each department make shopping a breeze. Customers usually don't have to ask how much items cost, since prices are clearly marked. And unless they're at a flea market or a yard sale, they don't bother trying to bargain. When customers are ready to check out, they find the nearest and shortest checkout lane. But as Murphy's Law would have it, whichever lane they get in, all the other lanes will move faster. Good stores open new checkout lanes when the lanes get too long. Some even offer express lanes for customers with 10 items or less. After they pay for their purchases, customers receive a smile and a warm "thank you" from the clerk. Many stores even allow customers to take their shopping carts out to the parking lot. That way, they don't have to carry heavy bags out to the car.
