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.

    “I could see a huge flow (流动) of water, coming down fast from very high. I had no idea of shape, or situation, or anything. It was just so big.”

    These are the words of the great English writer Charles Dickens. He wrote them when he was visiting Niagara Falls. This waterfall is on the border (边界) of the United States and Canada. It is one of the largest in the world, and the largest in North America.

    Niagara Falls is on the Niagara River. The river divides just before the waterfall, and there are actually three waterfalls. On the American side are American Falls and Bridal Veil Falls. Horseshoe Falls is mostly on the Canadian side. The name comes from its shape — like a horseshoe, in a half circle. Horseshoe Falls is the widest of the three.

    People mainly know about Niagara Falls because of its size and natural beauty. However, the Niagara River is also an important source of electricity.

    In the 1890s, the Westinghouse Electric Company built a large power system (电力系统) on the river. Many other companies also hoped to use the land around Niagara Falls for factories and power systems. However, around the same time, many people began to work to protect the natural area. Soon, the governments of the United States and Canada got involved with it. They protected the land around Niagara Falls. They made parks — green, natural areas. No one could buy this land for factories. For hundreds of years, millions of people have visited Niagara Falls to enjoy its beauty.

    At times my mom has been uncomfortable seeing these qualities in me. For example, when I was 12, I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my plane take off.

    But despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space to grow and learn even when it might have been difficult for her. When I reached my senior year, I decided to move away for college. Once again I found that I differed from my peers: while many of them wanted to stay close to home, I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of me going away, she was supportive and excited for me.

    One big thing I realized during my senior year, as my mom granted me more freedom, was that she actually believes in me and trusts me. That means a lot. Most of my life, and especially when I was little, the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards; getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's.

    I know that her high standards have helped me stay focused on what's important, like education, and made me who I am. I am thankful for her support and involvement in my life. Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

    In the online world, it's very difficult to talk to Chinese people without using emojis. However, did you know that people in different age groups have totally different preferences for choosing their emojis? The result is based on a report released by Tencent's WeChat, China's most popular messaging app, on its official weibo account on Wednesday.

    Specifically, for users who were born in the 2000s, their favorite WeChat emoji would probably be the widely used "facepalm", rumored to be based on the famous Hong Kong movie star Stephen Chow. They also may be a night owl without much sleep, while iced beverages and desserts are their cup of tea.

    For China's post-90s WeChat users, they are likely to get out of bed later in the morning compared with other groups, and the emoji "face with tears of joy" may rule their online social life. Also, their reading materials have shifted from entertainment and gossip three years ago to the current relationship and lifestyle pieces.

    For those born in the 1980s, their tastes have remained the same, as they are still fond of reading news on national affairs. And "smiling widely" is their emoji of the year.

    WeChat users born in the 1970s are called the optimistic group, who like to use the emoji "laughing quietly" and go through their moments frequently every day. Their bed time usually takes place around 11:30 pm.

    Users over 55 are the early-bird group with rich entertainment activities in WeChat platforms, such as looking through moments, reading and shopping. They like to cheer up other age groups, so their favorite emoji is "giving a thumbs-up".

    The report also indicates that WeChat boasts more than 1.08 billion active users with 45 billion messages being sent and 410 million calls getting through the app each day in 2018. In addition to covering users' socializing, WeChat has gradually come into our daily lives. Compared to the year before, people used WeChat 4.7 times more to purchase public transport tickets, and 2.9 times more to pay for medical expenses. Also, the app was used 1.5 times more over the previous year to pay for meals, with Beijing, Guangzhou and Shenzhen ranked as the top three cities in dining purchases through WeChat.

    Yesterday I went to the nursing home to visit my grandma. She just got out of the hospital recently where she had some serious operations. I wanted to surprise her after work so I stopped by for a quick visit.

    When I got there she was happy to see me. We hugged, kissed and exchanged greetings. Then I heard a woman crying. It was my grandma's roommate. The curtain was drawn so I could not see her. She started calling out a name that wasn't mine but she was certainly talking to me, begging me to go to her side of the room.

    I ignored her at first and continued visiting with my grandma. Then she started begging and saying, "Please, come to see me!" So I went to see her.

    When I drew the curtain back she looked so old but flashed me the biggest smile! She opened her arms wide for me to hug her so I bent low and gave her a hug. I sat on her bed and talked with her for a few minutes. She kept calling me by the other name but I did not correct her. She told me stories as if I had been there when they happened.

    Finally I went back to talk with my grandma. Then the other woman started crying again, saying, "Please, come back." She finally slept.

    I stopped by the nurse's station and the nurse told me that the lady suffers from Alzheimer's. I mentioned the name she had called me. The nurse told me it was the lady's daughter's name. Then I understood why she wanted me to go to talk with her.

    We will all get old someday. Some of us will have broken minds like my grandma's roommate and some of us will have broken bodies like my grandma. As I was leaving I promised I would go back and visit the lady, even after my grandma moved back to her home.

Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is worth our trust? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.

The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guilt-proneness (内疚倾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given 1, which they can choose to give to Player 2. Any money given to Player 2 is then automatically increased to 2.50. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a part of the money to Player 1. The researchers found more guilt-prone people were more likely to share the money with Player 1. Actually, in follow-up studies, guilt-proneness predicted trustworthiness better than other personality qualities the researchers measured.

Why might guilt lead to trustworthy behavior? The researchers found people who were guilt-prone also reported feeling a must to act in ethical (合乎道德的) and responsible ways while interacting (互动) with their partners in the game. People who are guilt-prone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again.

Then, how can we use this research to ascertain whether someone is trustworthy? "One way to do this might be observe how they respond to experience regret," lead author Emma Levine, assistant professor at the University of Chicago Levine, explains. Another way is to ask them to describe a difficult dilemma they faced in the past, suggests co-author Taya Cohen, associate professor at Carnegie Mellon University. This is particularly effective, Cohen and her colleagues have found, because it allows us to see if they're concerted about the effects their actions have on others.
