Half an hour into a cooking competition at Green Street Academy, Tyana Givens, 15, dipped a plastic spoon into a pot with tomatoes, bell peppers, onions, garlic and mushrooms over a burner in a science classroom. She and the two other students, Kalimah Ball and Maya Smith, were making meat sauce.

    The girls had spent the past five weeks learning how to grow their own produce using food computers-tabletop greenhouses controlled by computer programs-at Green Street Academy, a charter school in Baltimore. The course, which weaved together lessons on programming, food systems and agriculture, ended with an “Iron Chef”-style cooking contest.

    With the help of instructor Melanie Shimano, the girls finished their contest successfully using the food they planted in tabletop greenhouses. The tabletop greenhouses can control temperature, light and water inside using the computer code that the students wrote by themselves. Shimano, a 26-year-old entrepreneur, piloted(试行)the course as part of Green Street Academy's junior biotechnology class in the spring and will expand the program to other schools in the fall.

    “Technology is not something that a lot of teachers have a lot of resources for all the time, but it's something that's not difficult to do with a relatively low amount of funding,” Shimano said. “Baltimore is a center for startups and food, so kind of fostering that culture of being into technology and into design and seeing all the pieces fit together is really cool.”

    While her course is unique to Baltimore, it's part of a broader program born at the Massachusetts Institute of Technology's Media Lab called the Open Agriculture Initiative, or OpenAg, which aims to create inventive, sustainable food systems through open-source technology. In addition to 10 full-time staff and researchers, OpenAg is primarily an online community of about 1,400 educators, growers, chefs and retailers in 47 countries, according to Hildreth England, OpenAg's assistant director.

    “The interest level across the board generally comes from folks who are concerned about food systems and concerned about the environment, and it's usually a combination of the two,” England said.

    People all need friends because nobody wants to be lonely and a friend can help you in good and bad times. You've made friends since childhood, but you still don't know who your true friends are. Here are some signs to tell you if your friend is a true friend：

Always honest

    Honesty is important to keep a relationship alive. A true friend always tells you the truth. It may be hard sometimes but lying can destroy a friendship. It is important that your friend speaks honestly and never makes up stories.

    _________________

    There are always periods in your life when you have problems or difficulties. A true friend will always have time to listen to your problems and give advice. He or she may not be able to offer a solution to your problems but the fact that your friend made time to listen is a sign he/she cares for you. Your friend is not a true friend if he/she can never make time for you when you are in trouble. You also need to be reasonable and accept that your friend also has other things to do so he/she can't always listen immediately to your problems.

    Always respectful (尊敬的)

    A true friend will always respect your opinion no matter whether he/she agrees or not. Your true friend may disagree but never insists that he/she is correct.

    Always understanding

    It is possible that some problems will arise between you and your friend. A true friend will always be forgiving (体谅的) and understanding，even if it isn't his/her fault. We are all different people and we all make mistakes. A true friend is always forgiving and understanding because he/she doesn't want to take the risk of losing his/her best friend.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old son. Suddenly a crow (乌鸦) landed on their window.

    The father asked his son, "What is that?"

    The son replied, "That is a crow."

    After a few minutes, the father asked his son for the second time, "What is this?"

    The son said, "Father, I told you just now. It's a crow."

    After a little while, the father asked his son the same question for the third time, "What is this?"

    This time, the son said to his father in a low and cold tone, "It's a crow, a crow."

    After a moment, the father yet again asked his son for the fourth time, "What is this?"

    This time his son shouted at his father, "Why do you keep asking me the same question again and again? I have told you already, 'IT IS A CROW'. Are you not able to understand this?"

    A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page.

    Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn't at all feel angry, but instead felt affection for my son.

    If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. From today say this aloud, "I want to see my parents happy forever. They have cared for me ever since I was a little child. They have always showered me with love. I will take care of my old parents in the best way no matter how they behave."

    People in South Korea who feel they can no longer bear the stress of everyday life now can choose to stay in a prison to relax and think deeply.

    In a society where pressure to do well in school and find highly-paid jobs is intense, a former lawyer came up with an extreme relaxation idea. Kwon Yong-seok created the "Prison Inside Me" —a stress-reduction center with a punishment theme. People come here to cut themselves off from the outside world and pay to be kept in 60-square-foot (5.6-square-meter) cells (囚室).

    Located on the outskirts of Hongcheon, about 58 miles (93 km) northeast of Seoul," Prison Inside Me" came to life after Mr. Kwon voluntarily asked to spend time behind bars for" healing reasons," but his request was turned down." I didn't know how to stop working back then," he said." I felt like I was being swept away against my will, and it seemed I couldn't control my own life." So, Kwon and his wife Roh Ji-hyang decided to take matters into their own hands, and designed and built a prison-like spiritual center. The construction was completed in June last year and cost about 2 billion won ($19 million).

    The facility includes 28 cells, furnished with only a toilet, a sink and a small table, where guests can spend time alone, thinking about life and enjoying private thinking periods. Moreover, guests can also join group thinking periods in the hall, where they are given instructions on how to free themselves from what Mr. Kwon calls the "inner prison" to find inner peace.

    According to the Wall Street Journal, hundreds of stressed South Koreans are checking in at the stress-reduction facility to think about their lives and regain control of it. A two-night stay at" Prison Inside Me" costs 150,000 won ($146).

    Mr. Kwon and his wife explained that at the beginning they had a different plan for the" relaxation center," and imagined a longer stay for their guests, but, given that people weren't able to take more time off, they had to reduce the length of stays to just two days.

    Park Woo-sub, a guest at" Prison Inside Me," said the experience helped him a lot." This is my third time in prison. Being kept in a prison makes me hard to breathe, but it also offers time to focus only on me and spend some quiet time with myself."

    Others said the experience would have been more helpful if the conditions had been poorer, like in a real prison.

    Sandi Patty has been a name synonymous (同义的) with Gospel music because of her singing ability since she released her first album in 1979.

    Patty's newest book. The Voice, takes a deep dive into parts of her life she's kept private for years. Surprisingly, The Voice is not primarily concerned with Patty's singing voice. Patty was always a talented singer. However, she struggled to find her inner voice and speak up for herself. "I was a shy kid. Words were hard for me," Patty said.

    One of the reasons why Patty found it so difficult to use her voice was a traumatic childhood experience. At age six, she was abused by a friend, an experience she opened up for the first time in the book.

    She is sharing the story of her experience now, hoping it will help other people feel less alone. "Feeling alone keeps everybody silent about the tough times in our lives, so we think we're the only ones," Patty said. She wrote in The Voice that she felt like it was her job to make everyone feel better.

    Friendships were essential for helping Patty find the courage to speak up. They reminded her that she didn't need to make others feel better because the people she loved didn't doubt she cared for them.

    Friends and family were crucial for helping Patty confront another struggle she faced—shame. She felt unpleasant for insecurities about her weight and her divorce. "I've heard it explain that guilt tells us we have done something wrong and shame says we are wrong," Patty said.

    "I want people to know that their stories and their voices matter," Patty said. "We have to figure out a way to take our pain away and put it where it needs to be, without letting it guide our lives. Pain is a part of our story. It describes us, but it doesn't need to define us."

    Last night, when I went to see my grandmother, she was sitting alone at the nurse station with her word search book. My grandmother was sitting at the desk with her book but no pencil just staring at the letters as if she was trying to find the word. I came to her and said hello.

    Usually, she at least knows I am connected to her somehow but this time, she looked at me with doubt. I introduced myself and told her that I was her granddaughter. "I don't know who you are," she said." Do you want to go outside?" I asked. "okay," she said.

    We got her things and I wrapped it all in a blanket we would use as a tablecloth. I asked her if she could hold it while I pushed her wheelchair and held her cup of tea.

    She held her hands out and I placed the cloth bundle (捆) on her lap. I put the cloth on the table and she helped smooth it down-then I put the rest of the items on the cloth.

    Now she was just staring at me as if confused, as if trying to figure me out. "Do you know who I am?" I asked. She said, "I don't really know." "I am your granddaughter," I said. "I am not sure what that is. I don't know, I don't know you," she said.

    I think of my friend whose mother has not known him for years, has no recollection (记忆), and doesn't speak any more. It is a painful sight for all those living who remember. I am grateful that my grandmother is still so present. I have a sinking feeling that our days are numbered.

    For now, she is still here, still says thank you, and still loves me from a deep and secret place. Tomorrow, I will see her and she may or may not know me-and that will be okay. I still know her.
