Some years ago, writing in my diary used to be a usual activity. I would return from school and spend the expected half hour recording the day's events, feelings, and impressions in my little blue diary. I did not really need to express my emotions by way of words, but I gained a certain satisfaction from seeing my experiences forever recorded on paper. After all, isn't accumulating memories a way of preserving the past?

    When I was thirteen years old, I went on a long journey on foot in a great valley, well-equipped with pens, a diary, and a camera. During the trip, I was busy recording every incident, name and place I came across. I felt proud to be spending my time productively, dutifully preserving for future generations a detailed description of my travels. On my last night there, I wandered out of my tent, diary in hand. The sky was clear and lit by the glare of the moon, and the walls of the valley looked threatening behind their screen of shadows. I automatically took out my pen…

    At that point, I understood that nothing I wrote could ever match or replace the few seconds I allowed myself to experience the dramatic beauty of the valley. All I remembered of the previous few days were the dull characterizations I had set down in my diary.

    Now, I only write in my diary when I need to write down a special thought or feeling. I still love to record ideas and quotations that strike me in books, or observations that are particularly meaningful. I take pictures, but not very often—only of objects I find really beautiful. I'm no longer blindly satisfied with having something to remember when I grow old. I realize that life will simply pass me by if I stay behind the camera, busy preserving the present so as to live it in the future.

    I don't want to wake up one day and have nothing but a pile of pictures and notes. Maybe I won't have as many exact representations of people and places； maybe I'll forget certain facts, but at least the experiences will always remain inside me. I don't live to make memories—I just live, and the memories form themselves.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some degree our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person's intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

    It is easy to show that intelligence is to some degree something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligent. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.

    In my life, my grandfather has influenced me a lot. Ever since I was a little kid, I have always loved sports, especially football. My grandfather also enjoys sports and really loves football. He received a couple of awards in football matches. Through my three years so far in high school, my grandfather has helped me become a better player.

    Another reason why I admire my grandfather so much is because of his strong work ethic(道德). Ever since I was a little boy, my grandfather has taught me and shown me what good work ethic means. He is a good example. When he was a young man, his family owned a small store. He often helped his father run the store. He has also done several jobs in his life. He owned his own store when my mother was a young girl; he helped on a farm; he then had his own painting business. Now he is working at a Wal-Mart.

    Responsibility(责任) is something that I have struggled with in the past. My grandfather, on the other hand, is a very responsible person. That's why I am very responsible now, because of him. When he was in school, he was almost a straight A student. I, on the other hand, don't do so well. One day he had a talk with me about being more responsible. He helped me in school and made me realize how important grades are. Now I get almost As and Bs.

    Now you can see why I admire and respect my grandfather as much as I do. He is the best role model I have, and I will always look up to him.

    When a child says their first word, it's an event to remember. But when a girl with nonverbal autism (自闭症) does it, it's a reason to ugly cry in a parking lot. And that's exactly what happened to Briana Blankenship from Athens, Alabama. Doctors said her daughter, Taylor, might never speak. But just days ago, the 5-year-old girl challenged it and proved them wrong.

    “I had basically accepted that I would never hear her voice,” Briana said.

“We communicate with limited sign language and gestures,” Briana said, “We also have an iPad that is locked so that the only program she can access is a communication program called LAMP. LAMP is what she uses to complete work in school and because of this, she is excellent at spelling especially for a 5-year-old.” Taylor is also in the “inclusion” Kindergarten class where she receives occupational therapy (治疗) to help with her fine motor skills. “Her dad and I also pay for her to go to gymnastics every week and it has helped her stop her tiptoe walking”.

    However, when Briana was taking her daughter to a gymnastics class, the impossible happened. “We were on our way there- running late- so I had to go through the closest drive-thru to grab her something that she would actually eat We rarely eat fast food so she recognized that she was about to get her favorite food, French fries, and started getting excited and giggling (咯咯笑) in the back seat. That's when I heard her say it. I whipped my head around and asked “Did you just say Momma?” and she looked at me and said it again.

    I broke down into tears. “I parked my car after getting our food and immediately called my husband and then my mother. I didn't have time to call anyone else before class started so I quickly posted the video to my Facebook page.” Instantly, people flooded Briana's inbox. “We have had so many messages from people that we are giving them light for their loved ones, or that we are making them feel less alone in the daily battles of parenting a nonverbal child.

    Edward Latter, five, thought his dog Morse was gone for ever after cruel thieves took him away when the dog escaped from his home.

    The 10-month-old dog had been missing since December and the broken-hearted boy even wrote a heartbreaking letter to Santa and posted it to Lapland asking for his pal back for Christmas.

    A ￡10,000 reward was offered by millionaire Simon Cowell after he read about the horrific theft. Cowell said: "It's heartbreaking to see a little boy's Christmas ruined. Dogs are so important to many of us. We just hope it helps lead to the safe return of Morse."

    His parents, Amanda Hopkins and Richard Latter, had given up hope of ever seeing their pet again, until they got a call on Friday night. A couple 20 miles away from their home in Marden, Kent, had found a muddy dog walking through their street and thought it could be missing Morse. They brought the Morse in, washed him, and then called Mr Latter who was unsure until he was sent a photo, and then drove the family to the village of Meopham.

    The theatre carpenter, 40, said: "Amanda and I were still quite sceptical, but Edward saw him and recognised him straight away. He was absolutely over the moon. He said: 'I can't believe it, I have my best friend back. It's too late for Christmas but this is the best present ever.' We were still unsure if it was him though—as he wasn't responding to his name or coming to us."

    "We spent about an hour and half over there and we still were not sure, so we took him home to get his chip scanned. It was only when we took him to the vets on Saturday morning and got his chip scanned that we found out for sure. We instantly broke down in tears. We were just hugging each other, hugging Edward and hugging the dog." Added Richard.

    The family who found missing Morse said they hadn't yet heard from Simon Cowell about the ￡10,000 reward hut were happy to get him home.

    Most Americans see their pets as family members, surveys show. Those with dogs are more likely to call themselves pet "parents" than pet "owners". There are more of these parents than ever. In big cities such as San Francisco and Seattle,(owned) dogs outnumber children.

    The ways in which companies are profiting from the trend are also becoming various. Kinds of dog food and various pet mattresses (垫子) are always in hot sale. And it is not surprising that, for pets, Americans spent more than $400 million only on Halloween costumes this year. Overall, annual spending on pet food and products in America has risen by around 40% over the past ten years.

    Now a pack of startups have sensed a fresh opportunity.

    Much as Airbnb has offered travelers another choice instead of staying in a hotel, two firms, Recover and DogVacay, want to give pet owners an alternative to kennels (养狗场) when away from home. The cost is around $30 a night, with the majority of that going to the sitter, who takes care of the dog, and around a fifth to the company﹣much less than you would spend to check your dog into a kennel.

    The other big sellingpoint is that pets will receive better treatment. There are ways, apparently, to vet (审查) dog hosts to the real pet lovers: only around 15% of those who apply to serve as sitters are passed. Besides offering more attention and room, Rover has launched a feature that helps customers to see how far their dog has been walked via the GPS in the host's phone. Like Airbnb, both DogVacay and Recover insure stays against accidents.

    Another advantage of the model is that consumers often use dog-sitting services many times a year, and they tend to be loyal. That has helped DogVacay and Recover attract a lot of money﹣around $140 million between them.

    But firms that connect pets with hosts will face great competition as they try to go global. Companies offering homestays for dog rapidly appear in many different countries, including Australia, Brazil and Britain. And unlike Airbnb, which pulls in customers thanks to its presence in lots of markets that people want to travel to, the network effect for services like DogVacay is local.

    Despite having predicted the trend early, such firms may never achieve the same scale as an Airbnb. But then no one ever said it was easy to be top dog.
