    Many of us enjoy watching animals in the world. But do you know they can teach us?

    Geese(大雁), for example, teach us a very good lesson about 1. In the fall. Canada's geese fly to the warm south to get away from Canada's cold winter. They lift off in no order. Yet 2 they form a V shape, with one bird leading the group.

    This V shape allows geese to 3 energy. When the front bird moves its wings up and down, the resulting force of the air lifts the next one. This continues down the line. The bird in front has the 4 job. When it gets tired, it moves behind, and 5 bird moves into the lead By 6 the role, the group can travel great distances (距离).Geese flying in a V shape can fly 70 percent farther without rest than birds flying alone.

    7 the long flying travel, geese communicate with one another. They honk (鸣叫)to encourage the birds up front to 8 the speed. They also cheer each other 9 working toward a common goal.

    What have we learned from the lovely geese's experiences and skills? 10 together! Whether it is our personal lives or our jobs, we need other people. We need the spirit of teamwork!

    One morning, Ann's neighbor Tracy found a lost dog wandering around the local primary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day.

    Tracy took photos of the dog and printed off 400 FOUND fliers (传单) , and put them in mailboxes. Meanwhile, Ann went to the dollar store (一元店) and bought some pet supplies, warning her two sons not to fall in love with dog. At the time, Ann's son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old.

    Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her. As soon as she opened the door, riley dashed into the boy's room where Ann found Jack suffering from a heart attack. Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent.

    If it hadn't come to get me, the doctor said Jack would have died," Ann reported to a local newspaper. At this point, no one had called to claim (认领) the dog, so Ann decided to keep it.

    The next morning Tracy got a call. A man named Peter recognized his lost dog and called the number on the flier. Tracy started crying, and told him, "That dog saved my friend's son."

    Peter drove to Ann's house to pick up his dog, and saw Thomas and Jack crying in the window. After a few moments, Peter said, "Maybe odie was supposed to find you, maybe you should keep it."

    Kevin lived in a village in Africa. One morning, the teacher came into Kevin's classroom with a new girl. "Hi, guys! My name is Jenny. I am from America. I came to Africa with my dad. It's nice to meet everyone," the girl said.

    Kevin noticed (注意) that he looked different from Jenny. As soon as school was over, he ran home to ask his mother, "Mom, there is a new student Jenny in our class today. She comes from the US. Everyone in Africa has curly hair, right? Then, why is Jenny's hair straight?"

    Mom thought for a minute and said, "It's always hot in Africa. Curly hair is like a sponge (海绵) with many holes (洞), so the air can get in and out easily. If your hair was like Jenny's straight hair, you wouldn't be able to stand the heat (热). Our curly hair is necessary (必要的)!"

    For us humans, one of the greatest experiences is to taste all kinds of delicious food. But for penguins, they cannot get a taste of this happiness. That's because penguins can't actually taste the delicious flavors (味道) of their favorite food-fish!

    Scientists from the University of Michigan examined the genome (基因组)of five species of penguins. They found that no one can taste umami (鲜味),the flavor of meat or fish, the BBC reported.

    Many animals have five basic tastes: sweet, sour, salty, bitter and umami. But according to genetic data, penguins are believed to have only sour and salty tastes.

    These findings are surprising and puzzling. And scientists don't have a good explanation for them. But they have a few ideas.

    First, one of the umami genes doesn't work in cold temperatures. "It's about zero degrees when they eat cold fish," Zhang Jianzhi, the lead scientist, told the Daily Mail, so even if the penguins had a functional (功能的)gene, it might not work when they needed it.

    Second, penguins' tongues (舌头) are very special which may have something to do with their lack of taste. Instead of being covered with taste buds which help to taste food, penguins' tongues are very spiky. This is better for them to hold slippery (滑的) fish than tasting them. One study even showed that some types of penguins don't even have taste buds.

    However, penguins seem to be managing just fine.

    "Their behavior of swallowing food whole, and their tongue structure and function, suggest that penguins need no taste perception," said Zhang.
