It’s often said, “You can’t live only on air.” But now the Chinese scientists can tell you: Maybe you can.
Recently, some Chinese scientists have made a big breakthrough (突破). They turned CO2 into starch (淀粉).
Starch is the main part of rice and corn that we eat every day. Usually, it’s created by plants with CO2, water and sunlight. According to the team’s director Ma Yanhe, it takes the plants nearly sixty steps to produce starch. But now, the team, after six years of hard work, has found a simpler way to do this, with only eleven steps.
“Our study shows that creating something like starch is possible in a laboratory, and this technology may be helpful in many areas,” said Ma.
The scientists first turned CO2 and hydrogen (氢气) into methanol (甲醇). Then they made these methanol molecules (分子) into bigger and more complex (复杂的) molecules. Finally the starch came out.
This method makes it possible to produce food in factories instead of traditional farming. This will not only help make plenty of food, but also save water and land. It may also help recycle CO2 to deal with climate (气候) change, according to China Daily.
The study can be helpful in space, too. Astronauts may no longer need to worry about their food as they travel in space. They may simply turn the CO2 they breathe out into the food they eat!

China’s First Step in Man-made Food |
One year ago, I worked at a Chinese traditional medicine store. Business was not bad. Every day we mixed (混合）medicinal herbs(中药) for patients, so the store was always full of a strong herbal smell. After I had worked there for a time, a boy of 13 or 14 started coming and sitting on the stairs outside the store for a while every day. It seemed strange to me.
“Do you like the herbal smell?” I asked him one day.
“I grew up with this kind of smell,” he said. He told me that his mother took herbal medicine for years, so he could mix herbs for his mother when he was very young. He mixed the herbs with deep love, hoping his mother would get better as soon as possible.
“Is your mother well now? I asked.
He shook his head. “My mother passed away（去世）three years ago.” Looking up into the sky, he went on: “When I first passed by here and smelled the herbs, I thought of my mother. It is comforting to remember those days when she was alive. So I come here every day to sit for a moment.
