Homework is a major part of going to school: It's your teachers' way of evaluating(评价)how much you understand of what's going on in class. {#blank#}1{#/blank#}Luckily, you can do a few things to make homework less work.

    Be sure you understand the homework.

    Write your homework down in your notebook or day planner if you need to. {#blank#}2{#/blank#}It's much easier to take a minute to ask the teacher during or after class than to struggle to remember later that night!

    Use any extra time in school.

    Many schools have study halls that are specifically designed to allow students to study. It's tempting(诱惑)to hang out with friends during study periods or unstructured(松散的) time. {#blank#}3{#/blank#}

    Take a break.

    {#blank#}4{#/blank#}So take some breaks while doing your homework. Sitting for too long without stretching or relaxing will make you less productive than if you stop every so often. Taking a 15minute break every hour is a good idea for most people.

    If you don't finish your homework during school, think about how much you have left and what else is going on that day, and then budget your time. Most highschool students have between 1 and 3 hours of homework a night. If it's a heavy homework day and it seems like you've got an assignment in every subject but gym and lunch, you'll need to devote more time to homework. It's a good idea to come up with some kind of homework schedule（日程）, especially if you are involved in sports or activities or have an afterschool job.

A.Pace yourself.

B.Settle down to do homework.

C.And it helps digest important concepts(概念).

D.Most people's attention spans(注意力持续时间)aren't very long.

E.Don't be afraid to ask questions about what's expected.

F.Once your homework is done, you can check over it if you have extra time.

G.But the more work you can get done in school, the less you'll have to do that night.

    It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong.

    Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas — all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me.

    Then November 1,1991 began her month-long stay in the hospital—she suffered from a rare infection (感染)called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess(脓肿), and Grandma even made it into a local medical journal. Her doctor called her “the brain lady”.

    Grandma celebrated her 85^th birthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother!

    On 20th July 1969, millions of people saw Neil Armstrong take his first steps in space on television. Armstrong got out of the spacecraft Apollo 11, touched the ground of the moon and said, “That's one small step for man, one giant leap for mankind.”

    A conspiracy(阴谋)theory has existed since the night of his lunar handing. Armstrong's achievements were considered amazing, but people wondered if it really happened. Many people believe that the scene on the moon wasn't real. Rumours spread throughout coffee shops, street comers, and newspapers, but it soon died down.

    But theories resurfaced in 2001 Suspicion began when an American television network aired a program called Conspiracy Theory: Did We Land on the Moon? The show argued that NASA did not have the money for such a voyage, and that the whole scene was probably filmed in a movie studio. Many critics say that there were no stars in the background during the lunar landing, so it must have been a fake. They also point out that the American flag that was posted was waving. How could that be if there is no wind on the moon?

    NASA(National Aeronautics and Space Administration)has denied these rumours many times. They explained that now photographers can capture the brightness of the astronauts with the dimness of the stars behind them. Also, they said that the flag was waving because the astronauts were pulling it back and forth trying to get it deeper into the rock. NASA also points out that the television program fails to mention that Armstrong and his team brought back 800 pounds of rock from the moon.

    Nell Armstrong is seen as a national icon in the US and his lunar landing is one of the most historic events in the country's history. But either way, this conspiracy theory still exists today.

    Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “Mum, I can't peel(削皮) potatoes. I have only one hand.”

    Mum never looked up from sewing. “You get yourself into that kitchen and peel those potatoes,” she told me. “And don't ever use that as an excuse for anything again!”

    In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod(杆) to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.

    That night I told Mum about it. She hugged me, and I saw her “we'll see about that” look. The next afternoon, she took me back to school. At the deserted playground, mum looked carefully at the bars.

    “Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other elbow. Day after day we practiced, and she praised me for every rung(横杠) I reached.

    I'll never forget the next time, crossing the rungs; I looked down at the kids who were standing with their mouths open.

    One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mum came into my room. “Mum,” I said, weeping, “none of the boys would dance with me.”

    For a long time, I didn't hear anything. Then she said, “Oh, honey, someday you'll be beating those boys off with a bat.” Her voice was faint and cracking. I peeked(偷看) out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.

    We've heard of robots and AI（Artificial Intelligence）taking human jobs, but I bet mayors（市长）don't really think their jobs can be threatened any time soon. They were wrong, and the AI running for the mayor of a Tokyo district was clear proof of that.

    AI can't legally nm for high-ranking public management positions yet, but one mayoral candidate from Tama City, Tokyo, intended to maximize the use of artificial intelligence in running city affairs. He was running his campaign （竞选运动） as "AI Mayor". Basically, he was suggesting replacing human public officials with AI and having them collect city data and create fair and balanced policies that will benefit everyone.

    "For the first time in the world, AI will run in an election," human candidate Michihito Matsuda announced on Twitter. "Artificial Intelligence will change Toma City. With the birth of an AI Mayor, we will conduct balanced politics."

    The AI Mayor was campaigning very much like its human competitors. Posters were shown all over Tama City and campaign trucks were blaring out（大声鸣响）promises of an AI utopia （乌托邦）and asking for support.

    Some people called Michihito Matsuda's campaign a stunt （噱头）, as a human would still be the one legally in charge. However, others said that they were excited about the future of AI running things in the background, adding that it had to be a better choice.

What will you do if you can't eat everything bought in the canteen(食堂)? {#blank#}1{#/blank#} According to a survey, what students waste every year could feed over 10 million people. 

{#blank#}2{#/blank#} According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people. 

Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the west, for instance, consumerism, the belief that it's good to use a lot of goods and services, is often to blame for food waste. {#blank#}3{#/blank#}Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil (辛劳) others go through in order to provide them with the food they eat. 

{#blank#}4{#/blank#}There are 925 million hungry people in the world. They don't have enough food to eat. And farmers work very hard to grow the crops. {#blank#}5{#/blank#}It's also important that everyone thinks about how they can do their bit to reduce food waste. Recently a campaign against food waste launched on line in China might make you think twice about being so wasteful.
