第1821期:Astronauts eat space-grown food

Astronauts have been growing crops in space for years but this is the first time they’ve eaten the produce while still in orbit. It took the crew on the space station 33 days to grow the red romaine lettuce under LED lamps.多年来，宇航员一直在太空种植农作物，但这是他们第一次在轨道上吃到这些农产品。空间站的工作人员花了 33 天时间才在 LED 灯下种植红色长叶莴苣。Before they could eat the leaves they had to wipe them with sanitising cloths and then they added a little oil and vinegar. The verdict: "Good stuff", said one of the crew, saving a few leaves for the two Russian cosmonauts who were on a spacewalk while the feast was happening.在他们吃叶子之前，他们必须用消毒布擦拭它们，然后加入少许油和醋。结论：“好东西”，其中一名机组人员说，为在盛宴举行时正在进行太空行走的两名俄罗斯宇航员留了几片叶子。Nasa believes the experiment will help develop ways of making crews self-sufficient for longer journeys to places such as Mars. For now their judgement: one small bite for a man, one giant leaf for mankind.美国国家航空航天局相信，该实验将有助于开发方法，让宇航员能够自给自足地进行前往火星等地的长途旅行。目前他们的判断是：一个人咬一小口，人类一大片叶子。词汇表crops 农作物produce 农产品sanitising cloths 清洁布feast 丰盛的筵席self-sufficient 自给自足的judgement 判断，结论
