Light travels at a speed which is about a million times faster than the speed of sound. In one second, light travels about 300,000 km, but sound travels only 344m. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the Starter, you can see smoke come from his gun before the sound reaches your ears.
     This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays (光线) left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute. In some cases the light from one of tonight's stars started on its journey to you before you were born.

    Thus, if we want to be honest, we cannot say “The stars are shinning tonight.” We have to say, “The stars look pretty. They were shining four years ago but their light has only just reached Earth.”

    Anaya Elick was born without hands – she has stubs（残端）where most people's wrists begin.

    To hold a pencil, she must balance it between her wrists, then use her arms to push it along the page. But that didn't stop her from winning a national handwriting contest when she was in first grade.

    In the two years since, she has taken on greater challenges. Last week, she won another national handwriting contest, this one for cursive（草书）. And by all accounts from her teachers at Greenbrier Christian Academy, she has become an accomplished artist.

    Anaya isn't one to boast about her successes. She unwillingly says they make her proud but adds that they come from “lots of practice.”

    Her friends at school said, “She inspires everybody by what she does and how she does it” child to fail, and raising one who was born with a disability can heighten that protective instinct.

    Before Anaya was born, doctors knew about her condition, although not its cause. Other than having no hands, she is a regular 9-year-old girl.

    Anaya succeeds because she is not afraid to fail, Middleton said. The two began practicing cursive last year, when Anaya was in second grade. She struggled sometimes, because unlike traditional penmanship, which allows for breaks after each letter, cursive words are written straight through – and added effort for someone who must balance rather than hold the pencil.

    Middleton could see her daughter thinking through the challenge, figuring out how she could do better. She'd get frustrated at times, but she never hesitated to do things as often as it took to get them right.

    “I don't think I've ever heard Anaya say I can't do something,” Middleton said.

    That attitude carries over to her other interests.

    Recently, Anaya and her classmates sat in Cheryl Leader's art room, working on an exercise. The goal was to get them thinking about different concepts, like color combinations and how an image can be formed by fully coloring inside straight and diagonal lines.

    I grew up with a group of pets. As a mother, I was determined to provide my daughter with the same joyful experiences. Indeed, by the time my daughter was in elementary school, our house was known as "the neighborhood zoo". Now that she is a teenager, we've reduced the number of animals in our home, but we still live with two dogs. I can't imagine life without them.

    Regardless, I have become increasingly uncomfortable with the word "pet". When I came upon the conclusion by the University of Tennessee zoologist Gordon Burghardt that the best we can do for pets is a life of "controlled deprivation (剥夺)", I wished I had never bought Lizzy, our leopard gecko(豹纹守宫). I felt a pit in my stomach when I learned that Lizzy's constant clawing at the glass wall of her tank was most likely a signal of stress. It is perhaps not surprising that she died after only two years, despite our efforts to give proper care.

    The problems with the various small creatures we put into cages and tanks are relatively clear-­cut. More challenging moral questions, in my view, arise in relation to our closest furry friends: dogs and cats. Unlike animals that must spend their entire life in a cage or that must struggle to adapt to a human environment, most cats and dogs have it pretty good. Yet it is likely that our dogs and cats may be suffering in ways we don't readily see, because even the most well meaning owner doesn't always provide what an animal needs.

    It may be hard to recognize the harmful aspects of pet keeping when all we hear is how beloved pets are and how happy they are to be in our company. Advertisements showing golden­-haired children playing with golden-­haired puppies and YouTube videos of cats doing funny things make pet keeping look ever so precious.

    Yet if we really care about animals, we ought to know animals are not toys — they are living, breathing, feeling creatures.

    Keeping fit often means sharing a busy pathway with cyclists, runners and walkers, but imagine facing the task of doing it all without being able to see or hear. It is a challenge many disabled athletes face, unless someone agrees to be their eyes and ears.

    Newly formed group Achilles Brisbane pairs vision－and hearing－impaired（视觉和听觉受损的）athletes with a person who would like to guide them.

    “When we go out, we're always going out into an unknown course,”said Achilles Brisbane president Jane Britt, who is both vision and hearing impaired. “It's much less frightening to have someone beside you that has full hearing to listen for you and tell you what's there.”

    Ms. Cullen and Ms. Britt meet up most Saturday mornings to take part in the free five－kilometer Southbank park run. Their partnership is built on trust, but Ms. Britt said that it took time to develop.

    Ms. Britt said it took an unexpected storm for her to trust Ms. Cullen completely. “There was violent rain, my glasses were broken and we were walking together,”she said. “I suddenly had to tell her I couldn't see anything, and I was going to have to completely trust her. From that time I knew it was going to work because she was so good about dealing with the special situation we both found ourselves in. ”

    Isabella Allen and her seeing-eye dog Tatum are two new additions to the Achilles programme. Ms. Allen kept active by running and cycling but found it difficult to keep going as her vision became worse. After nearly giving up completely, she worked up the courage to ask Brisbane to find someone to share a boat with her.

    Ms. Alien said the fear of not finding anyone to row with almost stopped her from reaching out to Achilles Brisbane. “But, they found people and matched me to them.”she said, “It's the best thing I've ever done. ”

    Christmas is a great time with family and friends. One of the best ways to bond with (团结)one another is through games. So why not play some great Christmas party games?

    Present pickup is a great game for both young and young at heart. It can be played inside or outside. To prepare for the game, you will need to have some small boxes and some small gift bags. This is a great way to use the paper from last year. There should be as many presents as players. You'll also need four or more candy canes(甘蔗). Two large boxes can be used to drop the presents in.

    Two ropes will be needed. Take one rope and make a starting line. The other rope will mark the finish line. Place the large boxes at the finish line. Equally divide the presents into two groups. It's best to have an equal number of boxes and bags on each side to make it fair.

    The first player on each team will take two candy canes. When it's time to start, they'll pick up the presents only using the candy canes. Each player must run his present to the box or finish line and drop it in. If it's dropped on the way, the player starts over. After they drop their presents, the players will run the candy canes to the next players. This continues until all the presents have been picked up. The first team to finish wins.

    To play kids against adults, you may want to put easier presents in a group for the kids and more difficult ones for the adults. There are many variations to the game, so have some fun and come up with your own.

Recently I read Nineteen Eighty-Four,a novel by George Orwell set in a state where even the language they use is controlled.Adjectives are forbidden and instead they use phrases such as "ungood","plus good" and "double plus good" to express emotions.As I first read this I thought how impossible it would be in our society to have such vocabulary.However,the more I thought about it,the more I realised in its own way it's already happening.I type messages to my friends and alongside each is the emoji.I often use it to emphasise something,or to not seem too serious,or because this specific GIF conveys my emotions much better than I ever could using just words.And I wonder,with our excessive use of emojis,are we losing the beauty and diversity of our vocabulary?

English has the largest vocabulary in the world,with over one million words,but who's to say what it'll be like in the future?Perhaps we will have a shorter language,full of saying "cry face" if something sad happens or using abbreviations(缩写) like LOL(laugh out loud) or BRB(be right back) instead of saying the full phrase.So does this mean our vocabulary will shrink?Is it the start of an exciting new era?Will they look back on us in the future and say this is where it all began—the new language?Or is this a classic case of the older generations saying,"Things weren't like that when I was younger.We didn't use emoticons to show our emotions"?

Yet when you look back over time,the power of image has always been there.Even in the prehistoric era they used imagery to communicate,and what's even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later.Pictures have the ability to transcend time and language.Images,be it cave paintings or emojis,allow us to convey a message that's not restrictive but rather universal.
