Most animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.

    Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals(珊瑚) of the sea. In their skins they have tiny plants which act as “dustmen”, taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.

    The African elephant, the largest land animal remaining on earth , is of great importance to African ecosystem(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原)surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat(栖息地).

    It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

    Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

    What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

    Mr.Bean is an internationally recognized comedy character on TV and in films. He constantly gets into awkward and absurd situations, which greatly amuses audiences regardless of their nationalities or culture. The humor is always made clear through a series of simple and funny acts that rely purely on body language, which is universal.

    One of the remarkable shows is that Mr.Bean has a meal in a fancy restaurant. After being seated at his table, Mr.Bean takes out a card, writes a few words on it, seals(密封) it in an envelope and places it on the table. After a moment, he looks back at the envelope but this time he looks surprised, as if he did not know it was there. He opens it to find a birthday card and delightedly puts it on the table for everyone to see.

    When he looks at the menu, an astonished look swiftly appears on his face. He takes all the money out of his wallet, counts it and puts it in a saucer(茶托)．He then looks from the menu to the money with concern until he finds one thing that makes him smile. Then he orders a dish called "steak tartare". When the dish arrives, he is shocked to discover that "steak tartare" is actually raw hamburger. He makes an attempt to eat it, but it is clear from the look on his face that he finds the taste truly disgusting. He cannot hide his feelings, except when the waiter asks if everything is all right. When this happens, he smiles and nods, indicating that everything is fine. When the waiter is not looking, however, he busies himself hiding the raw meat anywhere he can reach-the sugar bowl, the tiny flower vase, inside a bun(小圆面包) and under a plate. He becomes so desperate in the end that he even hides some inside the purse of a woman sitting near him and throws some down the trousers of the restaurant's violinist!

    These days, North Kickapoo Street in Shawnee, Oklahoma, is a four-lane road leading out to the highway, and lined with all kinds of places to eat and shop. But in the mid-1950s, it was just a gravel(砂砾) country road, the perfect place for our daddies to teach us how to drive.

We didn't have driver's education at Shawnee High School. We were on our own. Mom took me to pick up an instruction handbook. I was the oldest of my friends, so we were excited at the prospect of a whole new world opening up. We'd have freedom to get around. Best of all, we could go to the Starlite Drive—In theater on 50-cents-a-carload night. We'd have it made.

    Mom let me back our 1949 Ford out of the garage a few times to get used to the clutch (离合器) and gearshift (变速排挡杆). I got familiar with the motion but was hardly ready for my road test.

    Finally, the day came for Daddy to give me a real lesson. He drove out to the end of the paved section of Kickapoo Street and across to where the gravel started. My daddy had come from a family of 10, and they had been farmers in a poor area in Oklahoma. There was only one way to do things, and that was the right way.

Praises were rare, so when he expressed his approval it was special. I didn't want to experience his glare if I ground the clutch or the car shook as I tried to get it going.

    I took a deep breath, slowly let out the clutch, pushed the stick into second gear, eased down the road, and then carefully moved into third gear. He had me stop and repeat the procedure two or three more times until I came to the end of the section. I was feeling pretty good as I came to a stop and looked to Daddy for approval.

He glared at me and then barked, “You've been driving, haven't you?” He must have thought I'd been practicing in somebody else's car. I quickly explained that my training was all done on the Ford.

    That was 60 years ago. I can still see the nod he gave me when he said, "Well, you did a good job."

    A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.

    Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.

    A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company's co-founder. He explains how they turn plastic into soft material for women's feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers arc then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe arc then attached to the shoe's outer part, called the sole (鞋底).This outer sole is also made from environmentally friendly material: responsibly responsibly sourced no-carbon rubber.

    Rolhy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. "We're not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled material to make other products.

    For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.
