After suffering through many months of unemployment  (失业). my wife and I moved this week from Colorado to Ohio. where she was starting a new job. Not knowing anybody there. we were pretty concerned about how we'd get our entire home unloaded (卸下) without killing ourselves.

    We made a phone call to hire (临时雇用) a couple of college students to help with all the heavy lifting once we got there. But one neighbor after another stopped by to help us. What ? Have we moved to some other country ? Maybe we've died and gone to heaven!     

    Unloading actually became fun and joy because there were so many wonderful new friends to help when we worked. The more people helped. the easier the work became. We were afraid the job might take days for the two of us alone. but it was finished in a few hours. Many total strangers would either walk by the sidewalk or drive by to ask us if we were moving in. Many were happy that this old house that had sat empty for so long was coming to life again. We were invited to an outdoor meal yesterday by neighbors on the same street.

    All the time. my brain was resting on this new sense of hope that people can be so friendly to strangers. Among all the conversation were lots of offers to help each other in all kinds of ways. It's wonderful to live in such a kind little town. I feel so grateful to be here. and wish the rest of the world could see how an entire community can model  (做榜样) what it's like to help each other.

    Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (蜷伏)with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which. ”

    Before age 11, children like to tell their parents what's on their minds. “In fact, parents are first on the list.” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”

    Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

    Many animals recognize their food because they see it.So do humans.When you see an apple or a piece of chocolate you know that these are things you can eat.You can also use other senses when you choose your food.You may like it because if smells good or because it tastes good.You may dislike sonic types of food because they do not look,smell or taste very nice.Different animals use different senses to find and choose their food.A few animals depend on only one or their senses,while most animals use more than one sense.

    Although there are many different types of food,some animals spend their lives eating only one type.The giant panda eats only one particular type of bamboo.Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage,even though there are plenty of other vegetables in the garden.However,most animals have a more varied diet.The bear eats fruits and fish.The fox eats small animals,birds and fruits.The diet of these animals will be different depending on the season.

In countries such as France and Britain,people eat foods with too much sugar.This makes them overweight,which is bad for their health.Eating too much red meat and animal products,such as butter,can also be bad for the health. Choosing the right food,therefore,has become an area of study in modern life.

    Hollywood's only Chinese-American superhero has stirred up heated debate on social media after she spoke out against discrimination in American show business.

    Chloe Bennet, a Chinese-American actress who stars in Marvel's trending TV series Agents of S.H.I.E.L.D., explained on social media why she changed her last name from Wong to Bennet, arguing that Hollywood is “racist” and wouldn't cast her with a last name that made them “uncomfortable.”

    “Changing my last name doesn't change the fact that my BLOOD is half Chinese, that I lived in China, speak Mandarin, or that I was culturally raised both American and Chinese,” replied Bennet.

    Bennet's remarks come after Ed Skrein stepped down from his role as Major Ben Daimion in the upcoming Hellboy movie for fear that his participation would be “whitewashing” a character of Asian descent(后裔).

    Racial barriers have been an essential problem in Hollywood. According to research conducted by the University of Southern California in 2015, nearly three-quarters of all characters in the top 100 films of 2014 were white, while only 5.3 percent of Asian artists can share the same privilege. In another report released in 2017, only 3.4 percent of over 1,000 surveyed films had an Asian director.

    “Asian artists can hardly stand out in Hollywood. Most roles starred by Asians are fixed and stereotyped, as if all Asians are good at math and martial arts. There is an invisible discrimination lurking(潜伏) in show business, as the difference of your skin color may bring disparity in your income and opportunities,” said Alex She, a New York-based Chinese-American photographer and movie maker.

    Bennet's experience has led to heated debate on both Chinese and foreign social media.

    While Jennifer was at home taking an online exam for her business law class, a monitor a few hundred miles away was watching her every move.

    Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked－remotely－to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?

    In the battle against cheating，this is the cutting_edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system，to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid—that students haven't just searched the Internet to get the right answers.

    Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of “open online courses.” Private colleges, public universities and corporations are jumping into the online education field. Spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.

    Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone numbers they once used.

    Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.

    February 14th is Valentine's Day! In China, it is only a day for boyfriends and girlfriends. But my teacher and my friends in America told me that Valentine's Day is a public day.

    This was my first Valentine's Day in America. I didn't understand the customs clearly. Maybe I didn't need to send any gifts. I watched others to see what they did, so next time I can understand.

    On that day, when we began the reading class, Mr. Peters gave every student some chocolates and said, “Happy Valentine's Day!” I was very happy. The teacher gave his students gifts and blessings! I never saw that in China. Maybe American teachers are very different. I didn't buy a gift for the teacher, so I owed a gift to the teacher. Anyway, I want to say, “Thank you teacher, and I'm sorry.”

When we had a break, one of my classmates gave me a Pokemon card. It was very funny. I felt we were children. I thought I owed a gift again, but I felt thankful. It was another gift, but it was from my new classmate.

    When we were moving to our grammar class, suddenly I heard someone calling me, “Shelly!” I stopped. Another classmate who had only been in our class one day gave me some chocolates. She said, “These for you and your friends. Have a good day!” I was looking at her leaving and thinking she spoke Arabic. We were in the same class only one day, but now we are friends. That's very good, but I owed a gift again.

    When I came home, my Chinese friend sent some roses and chocolates. I was surprised and happy because I had never received roses in my past life, but I hoped it was the last gift. I didn't want to owe more gifts.
