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.

    Can you understand this sentence? If you can't, don't feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on the Internet or cellphones. To newcomers, it can look like a completely foreign language.

    School teachers and parents say this new form of writing is harming (破坏) the English language. Increasing spelling and grammatical mistakes can be seen in students' writing. They fear the language could become corrupted (面目全非的).

    Everyone should just relax, say linguists (语言学家). They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nurnberg, from Stanford University, agrees. “People get better at writing by writing,” he says. “Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than, their parents.”

    Linguist James Milroy says, for centuries, it is believed without exception that young people are harming the language. And when today's teenagers become tomorrow's parents, they too will think this way. Milroy argues that languages do not and cannot become “corrupted”; they simply change to meet the new needs.

    However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, “I can understand Netspeak worries teachers and it's important that they tell their pupils that text messaging is for fun, but that learning to write proper English is a must for their future.”

    On August 5 just after 7.30 pm, Mike Estepa suffered a massive heart attack. The crazy cyclist was 40 kilometres into his Sunday ride when he stopped by the side of the road to text his family saying he'd be home in about 30 minutes. Moments later, he was lying in the ditch, unconscious.

    Larissa Arthur was driving back to Calgary from a hike in Field, B. C. with a friend. It was a warm and sunny day, and the two were chatting when a flush of yellow caught Arthur's eyes. She immediately pulled off the road.

    As Arthur approached the figure, she feared the worst: Estepa was covered in ants and exhibited no signs of life. There was no pulse and he wasn't breathing." says Arthur. A bystander called 911 and Arthur, a registered nurse, started chest compressions. She and two other drivers took turns carrying out CPR for the next 15 minutes before medical teams arrived and whisked Estepa away.

    Two days later, when Estepa woke up in the hospital, he was shocked to learn he had gone into cardiac arrest (心脏骤停). How did this happen, and, why was he lucky enough to have survived? He was full of gratitude and needed to speak with the woman who had saved him, whom he named his "angel".

    "It was emotional," says Arthur of her meeting with Estepa a few weeks later. Saving his life had extra importance for her: the bike she was returning from that day was one of 100 she's planned to honour her father, who died in 2017 after he fell during a hike that Arthur was meant to be on. "I couldn't save my father's life." Arthur says, "but this was a chance for me to save someone."

    My father loves his garden. He planted some seeds in it. But at that time I didn't understand why working in the dirt excited him so much.

    Unfortunately, in early May, my father was seriously injured in an accident. He had to stay in bed for a while. My mother had several business trips so she couldn't take care of the garden. I didn't want my father to worry, so I said that I would take care of his garden until he recovered. I assumed that the little plants would continue to grow as long as they had water, and luckily it rained fairly often so I didn't think much about the garden.

    One Saturday morning, my father said to me, "Christine, the vegetables should be about ready to be picked. Let's have a salad today!" I went out to the garden and was upset to see that many of the lettuce leaves and carrots had been half eaten by bugs. There were hundreds of bugs all over them!

    I panicked for a moment, but then I quietly went to the nearest store to buy some vegetables.

    When I gave the salad to him, he said, "Oh, Christine, what a beautiful salad! I can't believe the carrots are this big already. You must be taking very good care of my garden." I felt a little bit guilty.

    Coming home, my mother saw the bag from the supermarket in the kitchen. I was embarrassed and I admitted, "Dad wanted a salad, but the garden was a disaster. I didn't want to disappoint him so I went to the store." She laughed but promised to help me in the garden and weeks later I was finally able to pick some.

    I carefully made a salad and took it to my father. He looked at it with a hint of a smile. "Christine the carrots are smaller in this salad, but they taste better."

    Now, I better understand how putting a lot of effort into caring for something can help you appreciate the results more, however small they maybe. Perhaps this was one of the reasons for my father's love of gardening.
