Regarded as one of the English language's most gifted poets, John Keats wrote poetry that concentrated on imagery, human nature, and philosophy. Although Keats didn't receive much formal literary education, his own studies and passion brought him much success. Additionally, his own life situation influenced his poetry greatly.

    Growing up as a young boy in London in a lower middle-class family, the young John didn't attend a private school, but went to a public one. His teachers and his family's friends regarded him as an optimistic boy who favored playing and fighting much more than minding his studies. After his father's death in the early 1800s, followed by his mother's passing due to tuberculosis (肺结核), he began viewing life differently. He wanted to escape the world and did so by reading anything he could get his hands on.

    At around the age of 16, the teenage John Keats began studying under a surgeon so that he too might become a doctor. However, his literary appetite had taken too much of his fancy, especially with his addiction to the poetry of Ehmund Spenser. He was able to have his first full poem published in the Examiner in 1816, entitledO Solitude!If I Must With Thee Dwell. Within two months in 1817, Keats had written an entire volume of poetry, but was sharply criticized by a magazine. However, the negative response didn't stop his pursuit of rhythm.

    John Keats' next work was Endymion, which was published in May 1818. The story involves a shepherd who falls in love with the moon goddess and leads him on an adventure of one boy's hope to overcome the limitations of being human. Following Engymion, however, he tried something more narrative-based and wrote Isabella. During this time, John Keats began seeing his limitations in poetry due to his own limit in life experiences. He would have to have the “knowledge” associated with his poems. His next work wasHyperionthat would attempt to combine all that he learned. However, a bout (发作) with tuberculosis while visiting Italy would keep him from his work and eventually take his life in 1821.

    When you are travelling, whether on business or for pleasure, you often need to stay in a hotel. The kind of hotel you choose probably is decided above all according to how much money you want to spend. There are small hotels with very few services, where the prices are low, or there are large hotels with all the very latest comforts, where you could spend all the money you have in the bank for one very comfortable night.

    There are several different kinds of people who go to hotels. Some want to live, rather than just stay, in a hotel; the hotels which are designed to meet their needs are called residential hotels. However, most people who stay in hotels are either business people or tourists on holiday.

    In most hotels, there are two kinds of rooms: single rooms, for the use of one person, and double rooms, for the use of two people. In addition, in large hotels, there are also suites(套房), which include two or more rooms connected together—perhaps a bed-room and a living room. They are for people who are very rich or very important.

    It's that time of year when people need to lock their cars. It's not because there are a lot of criminals running around stealing cars. Rather, it's because of good-hearted neighbors who want to share their harvest. Especially with this year's large crop, leaving a car unlocked in my neighborhood is an invitation for someone to fill it with zucchini（西葫芦）.

    My sister, Sharon, recently had a good year for tomatoes. She and her family had eaten and canned so many that they had begun to feel their skin turn slightly red. That's when she decided it was time to share her blessings. She started calling everyone she knew. When that failed, she began asking everyone in the neighborhood, eventually finding a neighbor delighted to have the tomatoes. "Feel free to take whatever you want, "Sharon told her. Later that day, Sharon found that her garden had indeed been harvested. She felt happy that she could help someone and that the food didn't go to waste.

    A few days later, Sharon answered the door. There was the neighbor, holding a hot loaf of bread. The neighbor smiled pleasantly, "I wanted to thank you for all of the tomatoes, and I have to admit that I took a few other things and hoped you wouldn't mind. "

    Sharon couldn't think of anything else in her garden that had been worth harvesting and said so. "Oh, but you did, "the neighbor said. "You had some of the prettiest zucchini I've ever seen. "

    Sharon was confused. They hadn't even planted any zucchini. But her neighbor insisted that there really were bright-green zucchini in her garden. Sharon felt curious and decided to go to see where the zucchini had grown. The two of them walked together into the backyard. When the neighbor pointed at the long green vegetables, Sharon smiled. "Well, actually, those are cucumbers（黄瓜）that we never harvested, because they got too big, soft and bitter for eating. "

    The neighbor looked at Sharon, shock written all over her face. She gulped（哽住）a few times, and then, smiling, held out the bread, part of a batch she had shared all over the neighborhood. "I brought you a nice loaf of cucumber bread. I hope you like it. "

    Beyoncé Knowles can do something that many humans struggle with: sing and dance at the same time. But, it turns out this great ability is not unique to humans. The superb lyrebird, already known to be a gifted singer, can perform coordinated(协调的)song­and­dance routines(一套舞蹈动作)that put most humans to shame.

    The superb lyrebird is one of only two lyrebird species living in Australia, the other named Albert's lyrebird. Male lyrebirds have tails in the shape of an ancient musical instrument when spread out. Like most animals with beautiful body parts, the males use their tails to attract females. Each one sets up a small mound(小丘)on the forest floor, where he walks around proudly and sings. He also shows his tail by holding it over his head.

    Lyrebirds are gifted mimics(模仿者), so their songs combine their own calls, the songs of other species, and sounds they have heard in the forest. That would be enough showing off for other animals, but male superb lyrebirds also dance.

    Anastasia Dalziell of the Australian National University in Canberra filmed 12 lyrebirds in the wild. She found that males only danced during four song types, and that each song type was accompanied by a specific move. “Lyrebirds match different dance styles to different types of songs, ”she says. For example, when the male sang a series of rapid notes he also stepped to the side and held his tail wide. Another song type was accompanied by jumping and moving up and down, with the tail held narrow.

    “Our results suggest that the coordination between song and dance—like movements we see in humans can occur in other animals,” says Dalziell. Female lyrebirds might prefer males that are better at coordinating song and dance, although there is no evidence of that yet.

    The idea of turning recycled plastic bottles into clothing is not new. During the last five years, a large number of clothing companies, businesses and environmental organizations have started turning plastics into fabric to deal with plastic pollution. But there's a problem with this method. Research now shows that microfibers could be the biggest source of plastic in the sea.

    Dr. Mark Browne in Santa Barbara, California, has been studying plastic pollution and microfibers for 10 years now. He explains that every time synthetic (合成的)clothes go into a washing machine, a large number of plastic fibers fall off. Most washing machines can't collect these microfibers. So every time the water gets out of a washing machine, microfibers are entering the sewers and finally end up in the sea.

    In 2011, Browne wrote a paper stating that a single piece of synthetic clothing can produce more than 1, 900 fibers per wash. Browne collected samples from seawater and freshwater sites around the world, and used a special way to examine each sample. He discovered that every single water sample contained microfibers.

    This is bad news for a number of reasons. Plastic can cause harm to sea life when eaten. Studies have also shown that plastic can absorb other pollutants.

    Based on this evidence, it may seem surprising that companies and organizations have chosen to turn plastic waste into clothing as an environmental "solution." Even though the science has been around for a while, Browne explains that he's had a difficult time getting companies to listen. When he asked well-known clothing companies to support Benign by Design—his research project that seeks to get clothes that have a bad effect on humans and the environment out of the market, Browne didn't get a satisfying answer. Only one women's clothing company, Eileen Fisher, offered Browne funding.

    The English language has a lot of words which can be used in many different ways and in many different expressions.

    One such example is the word matter. In fact, matter can mean just about anything. It could be one of the most useful words in the English language.

    Let's get to the heart of the matter—a matter of principle (原则).

    If someone says that you owe (欠) him $50, but you don't, a friend might say, "Well, you could pay him the $50. It's not that much money. Then you won't have to hear him say it anymore." But if you do not owe him the money, do not pay him the money. It's a matter of principle.

    There is another way to use the word matter. But be careful with your choice of words.

    If you ask someone, "What's the matter?" it shows you are worried about the other person. But saying, "What's the matter with you?" has a completely different meaning. And it usually sounds rude (粗鲁的). In fact, when you say, "What's the matter with you?" you are suggesting that the person did something wrong or stupid.

    Another expression that could sound rude is to say, "It doesn't matter to me." Here, it depends on the context, and how you say it.

    Let's say you tell someone that a friend just got a big raise at work. That person answers with, "It doesn't matter to me." Here, it means he or she does not care. And it sounds rude.

    But saying, "Oh, you pick where we eat dinner. It doesn't matter to me." does not sound rude. In this situation, "it doesn't matter" shows you are easy-going (随和的).

    No matter how you look at it and what you say, matter is a very useful word. And it's only a matter of time before you will become an expert on the use of matter.
