When my sister Gina was born, she had a problem with her heart. Her heart was pretty bad in the beginning and she stayed in the hospital for a month. The first few years were very difficult because she was very sick. She had five operations before she was three years old. She had trouble walking, playing with other children, and going to school.

    Although Gina couldn't laugh and talk, we all knew that she just needed love and care. Our parents wanted to take Gina to a special place in Florida where she could swim with dolphins. Gina was afraid of swimming with them because she had never been around dolphins before. We had also never traveled that far as a family.

    When we got to Florida, we saw where the dolphins lived. It was a place where kids with special needs like Gina could come and spend time. I thought it was going to be a vacation, but it wasn't. Gina had to work hard every day for a week.

    The trip was amazing .Gina laughed and clapped(拍手) when she saw the dolphin, and the dolphin splashed (溅起水花) when it saw Gina. They swam together all day. Gina was able to move her body more than she normally did at home. Mom and dad were proud of Gina. I was, too.

    One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem—inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical (相同的) to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

    Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. The dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般的) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words was held.

    I live in the center of the city and there is a largeparking lot full of parking spots nearby. Rain is a rare occurrence in LA,so cars easilycollect pollutants and dust. Together with my friends,I decided it shouldbe a kind gesture to surprise the owners with a car wash.So we bought carwashing supplies and brought out all the bath towels we could find.With all the suppliesin hand, wewere able to convince another roommate to help out as well and we beganwatering down the cars.

    Every once in a while, someone would come by and asked usseemingly stupid men, "Who told you to wash the cars?" or, even better, "who paid you to wash their cars?" Weexplained we just wanted to do something kind. But our response was often me with aneven more confused look.

    As the afternoon went on, some other friends that came byunderstood our goal of the spontaneous event and started helping out with someof the duties. Firstone friend then two, and by the time we had cleaned the entire lot,we had an entire carwashing crew with independent individually assigned tasks and duties.

    I wasn't cleaning cars to be able to afford a new phone.I was cleaning carssimply because I wanted to offer the car owners kindness.There was noequipment to weigh our value created. We couldn't measure our success indollars earned over the time spent washing cars when we could have been earningtwice as much at work.

    I now realize, first hand, that there is a special energy createdwhen you choose to think bigger than yourself and act in service of others andmaybe, likeme, you'llfind it's actually the greatest gift you' you'll ever get.

    ARCHAEOLOGISTS (考古学家) GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities, then declined and disappeared quietly beneath the dense tropical forest.

    Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.

    This was surprising says an archaeologist, because we had a tendency to romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.

    All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.

    Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.

    "You could walk over the top of a major ruin and miss it, "says an archaeologist who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.

    Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.

    Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. "We still need to dig and hack our way through the jungle, but now we have a very accurate map to guide us."

    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.

Lack of sleep among children and teenagers in China has worsened in the past decade, with more than 80 percent getting insufficient sleep on school days, a new report has found.

Chinese youngsters snooze 7. 8 hours a night on average on school days, down 0. 3 hours from 2009, according to the report released on Monday by the Chinese Academy of Sciences'Institute of Psychology.

Researchers surveyed more than 15,800 students from Henan, Hebei and Guangdong provinces from April to July, asking what time they go to bed and wake up on days they take offline classes on campus.

Only 46. 4 percent of them sleep for at least 8 hours, compared with 47. 4 percent in 2009.

According to an action plan laying out measures to be taken from 2019 to 2030 to promote the health of citizens, primary school students are recommended to get a minimum of 10 hours of sleep a night. For junior high school and senior high school students, the recommended sleep durations per night are 9 and 8 hours respectively.

By this set of standards, more than 95 percent of students from primary schools, nearly 91 percent at junior high and 84 percent at senior high, did not get enough sleep on school days, heightening the risk of them developing cognitive, mental and physical health problems, the report said.

Hou Jinqin, a researcher at the National Institute of Education Sciences who co-authored the study, suggested local authorities implement measures instructed by the Ministry of Education, such as lessening academic burdens, postponing start times at school and encouraging children to be enrolled at institutions closer to home, in order to prolong sleeping hours.

In terms of the COVID - 19 outbreak's impact on sleep, she said available research overseas shows school closures forced by the COVID - 19 epidemic have added two hours of sleep to young students studying-gat home.

In China, some studies have revealed no marked differences in sleeping patterns of students before and after school reopened, she added.
