About this time every year, I get very nostalgic(怀旧的)．Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air，children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end.When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become.Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors.

    It is hard for me to accept that many of my wonderful neighbors are growing old and won't be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to these people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever.

    The “comings and goings” of the younger generation of my street are now mostly “goings”as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world was the gutter at the end of the street. We got pleasure from playing night games or from a breathtaking ride on a tricycle. Things are different now, as my friends become adults and move on. Children who rode tricycles now drive cars. The kids who once played with me now have new interests and values as they go their separate ways. Some have gone away to college like me, a few got married, two went into the army, and one went to prison. Watching all these people grow up and go away makes me long for the good old days.

    Perhaps the biggest change on my street is the fact that the city is going to turn my precious hill into several lots for now homes. For sixteen years, the view out of my kitchen window has been a view of that hill. The hill was a fundamental part of my childhood life; it was the hub of social activity for the children of my street. We spent hours there building forts, sledding, and playing tag. The view out of my kitchen window now is very different; it is one of tractors and  dump trucks tearing up the hill. When the hill goes, the neighborhood will not be the same. It is  a piece of my childhood. It is a visual reminder of being a kid. Without the hill, my street will be just another pea in the pod.

    There was a time when my street was my world, and I thought my world would never change. But something happened. People grow up, and people grow old. Places changes, and with the change comes the heartache of knowing I can never go back to the times I loved. In a year or so, I will be gone just like many of my neighbors. I will always look back to my years as a child, but the place I remember will not be the silent street whose peace is interrupted by the  sounds of construction. It will be the happy, noisy, somewhat strange, but wonderful street I knew as a child.

    Before you were my teacher, I thought that teaching was the last thing I wanted to do. Why would someone want to come in every day and attempt to instruct students, many of whom couldn't care less, or to get paid very little compared with the work he or she put in?

    You may have thought that the only thing I was learning from you was the course, but that's not all l learned. From reference books to funny jokes, you made each class exciting. You always tried to make class charming so that we could be excited about learning. However, those days have gone by.

    Whenever I was confused and needed extra help, you were the exact one to turn to. I would walk into your room for help and there would be several kids. You ran from one student to the next helping each one through their confusion. You could have gone back home after the bell rang. Instead, you chose to Stay and care about what your students did.

    You didn't only care about my learning, but you also cared about other things I was involved in. At the beginning of the year, we wrote down our hobbies and interests. You remembered what we wrote, too. I had missed class for track meets (田径运动会)and when I came back the next day, you would ask me how it went. Many of the teachers never bothered to ask what I liked to do.

    These things showed me the value of teaching. They showed me how much of an influence a teacher can have on a student. I want to be the one that influences students and pushes them toward success. I want students to leave my classroom thinking that their time was worthwhile (值得的). I want to be the inspiration for them that you were for me. Whenever it gets hard for me to continue on this path, I'll remember you and what you did for me.

    Bees in a colony work with each other to gather food, and they try to find the most nectar (花蜜)in the least amount of time possible. A small number of bees work as searchers, but when a good flower patch (花丛) is found, how do they tell other bees where to find it?

    Bees communicate flower location using special dances inside the hive, where bees live. One bee dances while the other bees watch. The dancing bee smells like the flower patch, and also gives the watching bees a taste of the nectar she has gathered. Smell and taste helps other bees find the correct flower patch. Bees use two different kinds of dances to communicate information: the waggle (摇摆) dance and the circle dance.

    Waggle dance

    The waggle dance tells the watching bees two things about a flower patch's location: the distance and the direction away from the hive.

A. Distance

    The dancing bee waggles back and forth as she moves forward in a straight line, then circlesaround to repeat the dance. The length of the middle line, called the waggle run, shows roughly how far it is to the flower patch.

B. Direction

    Bees know which way is up and which way is down inside their hive, and they use this to show direction. How? Bees dance with the waggle run at a specific angle away from straight up. Outside the hive, bees look at the position of the sun, and fly at the same angle away from the sun.

    Circle dance

    The circle dance tells the watching bees only one thing about the flower patch's location: that it is somewhere close to the hive.

    In this dance, the bee walks in a circle, turns around, then walks the same circle in the opposite direction. Sometimes, the bee includes a little waggle as she's turning around. The duration of this waggle is thought to indicate the quality of the flower patch.

    Poetry is the artistic expression of the human thoughts and feelings in rhythmical and emotional language. Compared with prose (散文) , it lays more stress on rhythm, imagery (意象), emotion, and imagination. As its language is rhythmical, its sound is highly musical. We may say, "No rhythm, no poetry", no matter the rhythm of poetry is traditional as in metrical (格律的) style or "natural" as in free verse.

    So the poet must write carefully and reflectively in order to find words that not only fulfills the demands of meter and rhyme, but also expresses the meaning in a manner that complements the imagery and tone of the rest of the poem. This careful use of language is the most significant difference between ordinary prose and poetry.

    The ordinary prose writer neatly builds an argument using words the way a mason (石匠) builds a house using bricks; the poet is an artisan who creates a fieldstone hearth (大卵石壁炉炉床) — each stone or each word is turned over  examined, and often laid aside until it can be placed where its shape, weight, and color will contribute to the strength and beauty of the whole. Prose, according to Samuel Taylor Coleridge, is "words in their best order", and poetry is "the best words in their best order".

    The reader's chief delight in reading poetry comes from his response to its musical effect, which comes from many metrical patterns represented in conventional iambic (抑扬格) feet or from repetitions and parallel phrasing shown in free verse and from other elements of poetry.

    No matter which place you decide to visit in Spain, you'll find a beautiful beach waiting just for you. These popular beaches can meet the needs of people from all walks of life.

    Cala de Algaiarens, Minorea

    With soft golden sand and clear water, this beach is perfect for snorkeling (浅滩潜水) and visiting underwater caves. The beach belongs to a local man, so tourists have to pay a small entry fee. The waves here can sometimes be huge so the beach isn't safe for kids.

    Cala Tarida, Ibiza

    Besides the big music festivals and the exciting nightlife, Ibiza is home to some of the most beautiful beaches; one of them is Cala Tarida. Just relax on the white sand or go swimming in clear water. It is an ideal location to spend a sunny day if you are in Ibiza.

    Beach of La Concha, San Sebastian

    It has been called the best city beach not just in Spain, but also in Europe. It's so popular during the holidays that tourists have to struggle to get some space. Even though the beach is a 10- minute walk from the city, the white sand and the amzing clear waters do make the city a new world.

    Sotavento, Canary Islands

    As an ideal choice for travelers, Sotavento offers 17 miles of white sandy beach. It is blessed with strong water and winds, making it a paradise (天堂) for surfers and kite flyers. The beach also hosts the popular World Kite Surf Championship every August.

    Better known by his stage name Kun, Cai Xukun is, without a doubt, one of the most popular stars in China.

    On July 26, the 21-year-old dropped his new single Young. Within just 20 seconds, it reached 1 million views and in only 3 days topped the music charts of Tencent's QQ music.

    Cai wrote the song by himself to share his understanding of modern-day youth. The singer has mixed R&B with electronic music to make his new beat cheerful. One reviewer wrote on QQ Music: "When you listen to the song, you just seem to go back to youth again."

    August 2 is Cai's birthday, and the song was a gift to himself. The singer hopes that he can always have the courage to follow his love of music, ignoring what anyone says. "My works are like my children and I have put my best effort into them. I want every piece of my work to have my own spirit in it. I feel more enjoyment when I am performing my own work." He told the Global Times.

    To find new inspiration, Kun attends different kinds of musical performances－from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told i-D.

    With talent and dedication(专注) to music, Cai is expected by many to make his mark in the competitive Chinese music industry.
