Dolphin or not a dolphin? That is the question! You see, there are several types of dolphins. Some are saltwater dolphins while others are river dolphins.

    "What are the 32 types of dolphins?" When people are asking the question, they are actually referring to the saltwater dolphins in oceans and seas. The river dolphins living in fresh water are not included in these species. But what would be the answer in this case if we ask. "Dolphin or not a dolphin?" The answer would obviously be yes. River dolphins still belong to the dolphin family.

    Among the 32 types of dolphins do not actually wear the word "dolphin" in their names, such as the tucuxi, while others actually have the word "whale" as part of their names even if they are not whales but in fact, belong to the dolphin family, for example, the melon-headed whale and the killer whale. So what would be the answer to the question "Dolphin or not a dolphin?" in these cases? It would be yes. All these species do belong to the dolphin family.

    Another question that people ask is. "Are the sea animals that perform at aquariums(水族馆)all dolphins?" So ,it always seems to come back to the question, "Dolphin or not a dolphin?" Well the answer is no in this case. The sea animals that perform there are not all dolphins. The beluga which people tend to think belong to the dolphin family because they show what seems like a smile, like most dolphins, are in fact a species of the whale family.

    Now that you read these facts about dolphins, you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family but in either case, it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin. That is the question ！

    Honey (蜂蜜) from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest (巢) and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.

    The honey guide does not actually like honey, but it does like the wax (蜂蜡) in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.

    Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

    I began writing poems fifteen years ago while I was in college. One day I was in the library, working on a term paper, when I came across a book of contemporary poetry. I don't remember the title of the book or any of the titles of the poems except one: “Frankenstein's Daughter.” The poem was wild, almost rude, and nothing like the rhyme-and-meter poetry I had read in high school. I had always thought that poetry was flowery writing about sunsets and walks on the beach, but that library book contained direct and sometimes shocking poetry about dogs, junked cars, rundown houses, and TVs. I checked the book out, curious to read more.

    Soon afterward, I started filling a notebook with my own poems. At first I was scared, partly because my poetry teacher, to whom this book is written for, was a serious and strict man who could see the errors in my poems. Also, I realized the seriousness of my devotion. I gave up geography to study poetry, which a good many friends said offered no future. I ignored them because I liked working with words, using them to reconstruct the past, which has always been a source of poetry for me.

    When I first studied poetry, I was single-minded. I woke to poetry and went to bed with poetry. I memorized poems, read English poets because I was told they would help shape my poems, and read classical Chinese poetry because I was told that it would add clarity to my work. But I was most taken by the Spanish and Latin American poets, particularly Pablo Neruda. My favorites of his were the odes ― long, short-lined poems celebrating common things like tomatoes, socks and scissors. I felt joyful when I read these odes, and when I began to write my own poems, I tried to remain faithful to the common things of my childhood — dogs, alleys (小巷), my baseball mitt (手套) and the fruit of the valley, especially the orange. I wanted to give these things life, to write so well that my poems would express their beauty.

    I also admired our own country's poetry. I saw that our poets often wrote about places where they grew up or places that impressed them deeply. James Wright wrote about Ohio and West Virginia, Philip Levine about Detroit, Gary Snyder about the Sierra Nevadas and about Japan, where for years he studied Zen Buddhism (禅宗佛教). I decided to write about the San Joaquin Valley, where my hometown, Fresno, is located. Some of my poems are absolute observations and images of nature — the orange yards, the Kings River, the Sequoias (红杉). I fell in love with the valley, both its ugliness and its beauty, and quietly wrote poems about it to share with others.

    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.

    I was selfish as a teenager. I usually spent my time thinking about myself and taking care of my own needs. I let my older brother do most of the work around the house until he left for college. I let my mom and dad worry about our bills and problems while I read books, played, and lost myself in my own imagination. This didn't change even when I went to college either. I studied hard but only to make my own life better. Even when I started to explore my faith, it was only to increase my own happiness.

    I married after graduation and decided to start a family. Of course, I had no idea what hard knocks reality had in store for my selfish soul. Soon I found myself unemployed, deeply in debt, and with a new baby on the way. I found out that life has little sympathy for spoiled people. In fact, all of the struggles I was going through were beating the selfishness slowly out of me.

    Still, I didn't give up on happiness. I knew that there must be a way to find it. I finally realized, however, that it had to include more than just my own needs, wants, and desires. The answer began to make itself clear one night shortly after my baby boy was born. I got a bottle and held him in my arms. As I was feeding him I looked down and saw his big, innocent, trusting eyes. I smiled and talked to him. Then he smiled and I could feel my heart growing, expanding with love. I felt such peace and joy. At that moment I had a hint of the truth: it is by growing our hearts with love that we find our happiness.

    Carolyn Arends wrote:" The more people you let into your heart, the bigger your heart gets. The more love you get, the more love you have to give. It just keeps growing." So, keep loving, keep living and keep caring. Keep growing your heart today, tomorrow, and always.

    In Britain. Boxing Day is usually celebrated on December 26th, which is the following day after Christmas Day. However, strictly speaking, Boxing Day is the first weekday after Christmas. Like Christmas Day, Boxing Day is a public holiday. This means it's a non-working day in the whole of Britain. When Boxing Day falls on a Saturday or Sunday, the following Monday is the public holiday.

    The exact origin(起源)of the holiday is unclear. One of the thoughts is that during the Middle Ages, when great sailing ships were setting off to discover new land, a Christmas Box was placed by a priest(神父)on each ship. Those sailors who wanted to ensure a safe return would drop money into the box. It was sealed up and kept on board until the ship came home safely. Then the box was handed over to the priest in exchange for the saying of a mass of thanks for the success of the sailing. The priest wouldn't open it to share the contents with the poor until Christmas.

    One more thought is about the "Alms Box" placed in every church on Christmas Day. Worshippers(做礼拜的人) put gifts for the poor into it. These boxes were always opened the day after Christmas. That is why that day became known as Boxing Day.

    Today, many businesses, organizations and families try to keep the traditional spirit of Boxing Day alive by donating(捐赠) their time, services and money to aid Food Banks, providing gifts for the poor, or helping families in need. Besides, spending time with family and shopping are popular Boxing Day activities now.
