As a boy, Charles Robert Darwin(达尔文) collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him.

    His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin's interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin's great life.

    As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.

    Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin's great book “On the Origin of Species by Means of Natural Selection”(《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.

    Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was still working on 17, April, 1882. He was dead two days later.

    I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled（贴标签）everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

    War broke out one evening. Kate came into the room. Soon, I heard her screaming. “Take your shoes away! Why under my bed!” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

    The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled（爬）under her covers, sobbing.

    Obviously, that was not something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart.

    Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, “Thanks.”

    Kate and I stayed roommates for the rest of the year. We didn't always agree, but we learned the key to living together: giving in, cleaning up and holding on.

    Doctors in Britain are worried because British teenagers eat lots of fried potatoes, sweets and fat food. Most teenagers don't have enough fruit or vegetables and more than one million British school children are overweight.

    Some teenagers say that they don't have time to eat good food, but kids who have a poor diet often have health problems when they are older.

    Americans have been with fast food for a long time, and it was born there. American fast food is now a part of life far beyond the stores of the United States. McDonald's, Pizza Hut, and KFC have restaurants all over the world.

    No one can say no to the fact that fast food at a fair price has its place around the world. It is popular now, and it is giving a hand to a country's economy (经济).

    A diet of hamburgers, fries and soda may seem happy, but it won't give your body things you need to stay healthy. Fast food has little of many important things our bodies need.

    Some parents are saying no to the fast food restaurants where people eat junk food and doctors are giving young people books and games about a good diet. Having a healthy and well-balanced diet can help you feel better and live longer.

    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.

    Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.

    The findings contradict research published earlier this year showing that returning adult children trigger a significant decline in their parents' quality of life and wellbeing.

    The young adults taking part in the study were "more positive than might have been expected about moving back home—the shame is reduced as so many of their peers are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often slipping back easily into teenage patterns of behaviour, the study found.

    Parents on the whole were more uncertain, expressing concern about the likely duration of the arrangement and how to manage it. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.

    The families featured in the study were middle-class and tended to view the achievement of adult independence for their children as a "family project". Parents accepted that their children required support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out and get on the housing ladder.

    "However", the study says, "day-to-day tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates".

    Areas of disagreement included chores, money and social life. While parents were keen to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple—eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be the so–called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV—where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too. The researchers added, "Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start."

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, "This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful."
