A long time ago people thought that the sun went round the earth. In some countries people even said that the sun was a god(神). They thought the god drove across the sky each day on a golden horse. Now we know the earth goes round the sun. It takes the earth a year to go a circle(圈) round the sun. Today men even know how far it is for the earth to go round the sun. They tell us that the earth travels over a thousand miles a minute on its journey round the sun.

    The sun is really a star. It is much bigger than the earth and it is very hot. Some people have been to the moon but we know that no one can ever go to the sun. It is far too hot for people to live anywhere near it. The sun is three hundred thousand times heavier than the earth and more than million times larger.

    Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood. When I was a boy of 12, something happened to me that cured me forever of wanting to put any wild creature in a cage.

    We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. It's the most beautiful sound in the world.

     I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

    I finally succeeded in catching one and put it in a cage. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

    I had left the cage out on our back porch, and on the second day, my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see how my pet bird was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

    Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries(浆果). She thinks it better for her young to die than to live in captivity.”

    Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

    Do you like shopping? Or does the thought of wandering round the shops fill you with terror? For some of us, shopping is an enjoyable way of spending our spare time and our money. For me, it's something I would rather avoid. Thank goodness for the Internet! It's more convenient to buy CDs, electrical items, and even food from the comfort of your sofa. But that's not the only reason: price is an important factor. We can buy goods and services cheaper online. But sometimes the problem is knowing what to buy. This has led to a type of shopping called “showrooming”.

    Showrooming is something I've done. I will go to a shop to see, touch and try out products but then go home and buy them online at a knock-down price. I'm not alone in doing this. Research by a company called Foolproof found 24% of the people showroomed at Christmas in 2013.

    Amy Cashman, Head of Technology at TNS UK, says the reasons for this new shopping habit are that people are lacking time, lacking money and they want security about the products they are buying. She explains that consumers are not only shopping online at home but they are using the Internet in store or on their smart phones to shop around.

    But does this mean technology will kill shops? Certainly shops will change. They will have to offer more competitive prices or encourage people to buy more by giving in-store discounts or free gifts.

    We mustn't forget that buying in a shop means you can get expert advice from the sales assistant and you can get good aftercare. It's good to speak to a real human rather than look at a faceless computer screen, but at least by showrooming, you get the best of both worlds.

    When Hai started college, he weighed over 250 pounds Healthy food choices were difficult for him, and he was emotionally distraught (忧心忡忡). However, when he left home for college, he was able for the first time to start taking his life and weight into his own hands.

    He started by shopping at a local farmers' market, an experience that inspired him profoundly. The idea that a farmer's market represents local, sustainable, healthy food with a human connection where you can interact with the people that grow your produce was extremely appealing to him, and he began to think about the food that people at his university were eating. From what he saw at farmers' markets, Hai realized that dining hall food was not “real” food.A lot of it is frozen or processed, and has unhealthy additives. His ideas continued to develop as he started taking classes about food sustainability at university, and after the summer of 2014 during which he cooperated with other students9 he launched into his senior year at the University of California full force with the Real Food Challenge (RFC) campaign, a project he co-founded that aims to reinvest university spending in food that is “real”: ecologically-sound, community-based, humane, and fair; as opposed to those traditional purchases with those unhealthy additives and processed products.

    Not only has Hai started a movement of change across the university dining system, but he has also grown extremely as an individual，now with strong leadership abilities and great vision. In addition, after he started learning about food sustainability and taking action at university, Hai has lost over 100 pounds, and has been able to start enjoying activities such as backpacking and swimming that were not a possibility for him previously. He is confident instead of distraught now.
