Let children learn to judge their own. A child who learns to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Little by little, he makes the necessary changes to make his language like other people's, in the same way, children learn to do all the other things without being taught—to walk, run, climb, ride a bicycle—compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not. If it is a matter of right answers, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should our teachers waste time in doing such work? Our job should be to help the child when he tells us that he can't find the way to get their own understanding, how to know what they know or do not know.

    My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that ploughed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $1 a day, I worked eight hours straight, with no food breaks.

    It was very tedious work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I've never been late for any job since. I also learned about being respectful and faithful to the people you work for. More importantly, I earned my pay; it never entered my mind to say I was sick just because I didn't want to work.

    I was only six years old, but I was doing a man's job. Our family needed every dollar we could make because my father never earned more than $18 a week. Our home was a three-roomed wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem(自尊心), one of the most important things a person can have.

    When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed, so the golfers could find them. Losing a ball meant you were fired, so I never missed one. Some nights I would lie in bed and dreamt of making thousands of dollars by playing golf and being able to buy a bicycle.

    The more I dreamt, the more I thought. Why not? I made my first golf club out of guava limb(番石榴树枝) and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity. I learned working in the field—except now I was driving golf balls with a club, not oxen with a broomstick.

    Australia is a developed country and the future of its solar industry is looking bright after a record 3.5m panels (嵌板) were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (生产能力) in small-scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.

    Australia's solar power prosperity could almost double capacity in a year. The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solarchoice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.

    The regulator's executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions.

    “We are seeing a wide cross-section of Australians-households, community centers, schools, and small businesses-receiving rewards under the small-scale renewable energy scheme,” Williamson said. “Our data shows consumers are embracing renewable energy to take control of their electricity bills.”

    In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57%. “The data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength. It looks like 2018 will be another big year for the solar industry.”

    The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria's Latrobe Valley has a capacity of 2,200MW.

    I live in Mumbai, India, a big city, but I came from a remote Kerala village. When I was a boy, hardly anyone spoke English around me. So, at age nine, Dad sent me to Montfort, an exclusive boarding school. There, I had to speak English or be punished. My uniform was typical English public school: grey jacket，tie，and black leather shoes-so different from the clothes most people in my village wore. And our official school sport was cricket, something I'd never heard of, let alone played, before arriving.

    Montfort had been built for the children of the British officials who once ruled India, but by the time I arrived in 1961, nearly all the students were from powerful Indian families. Its English traditions, however, continued.

    When I returned home for the holidays still wearing my uniform, people stared at me like I was an alien. "Speak some English," they teased. Looking back, I unwittingly brought a bit of English culture to my village.

    But English and too much Western influence are precisely what many traditionalists and politicians fear. They ask: Will such influences finish off our own culture?

    Various leaders have tried to erase the British traditions, pulling down old British statues and replacing many British-rule city names with older native names. Some even suggest changing our weekly day of rest from the "Western" Sunday to the "Hindu" Tuesday.

    Extreme responses I say. You can't change history, and it's only natural for foreign influences to affect a nation's culture. So Indian culture, as it is today, is really a mixture derived from centuries of foreign invasions.

    Add to that the massive changes of the 20th century resulting from the television, jet-age travel, the Internet, etc.

    Everything from clothes and language to food keeps changing, yet we remain Indian. I believe that Asian cultures are too ancient and deep-rooted to be weakened by foreign influences.

    Allow me to illustrate my point. Some time ago, I took my visiting Singapore-born-and-raised cousin to a Chinese restaurant for dinner. Later, while driving home，I talked about the fine Chinese food we'd just had.

    "Was that Chinese food?" my cousin exclaimed. "Oh, I didn't know." It must have tasted too Indian for him to realize it.

    Meanwhile, like countless others, my village has transformed over the past decades. Many people wear modern clothes and TV brings cricket into local homes. There's even an English- language school, where you can hear kids giggling, yelling, flirting-all in English, but with an Indian accent. Just like the Chinese food you get in India.

    Are these foreign influences something to worry about? I don't think so. India's Chinese food tastes pretty good to me!

    I must have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don't remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.

    I always wanted to know what my mom was reading. Hearing mom say, "I can't believe what's printed in the newspaper this morning," made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.

    This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, "The C-A-N-D-Y is hidden on the top shelf," I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.

    Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A's on my tests. Sometimes, I would read a novel that was assigned, but I didn't enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract left too much room for argument.

    Now that I'm growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don't have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.

    We're taught to read because it's necessary for much of human understanding. Reading is an important part of my life. Reading satisfies my desire to keep learning. And I've found that the possibilities that lie within books are limitless.

    A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.

    Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.

    Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, "From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy."

    "It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone said.

    Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. "But there was no strong empirical data for that recommendation," Ambrosone said.

    So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy's effectiveness. They looked for evidence in an earlier study on diet, exercise, lifestyle and cancer results.

    In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.

    The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.
