問題詳情
閱讀測驗Do you want something different for dinner? Try some space food. Scientists are experimenting withways to grow food in space. Scientists think that in 20 or 30 years, astronauts will be able to live in spacecolonies off the planet. Already many scientists are living for months on the International Space Stationhigh above the earth. It’s too expensive to carry food to feed people living in space colonies. People inspace colonies will need to grow food for themselves. But how can they grow food without soil andsunlight?Today, we already have hydroponic vegetables. These are vegetables you can grow without soil. Thefood can grow in an artificial environment. The science of hydroponics is not new. Many writers believethat the Hanging Gardens of Babylon were actually a large hydroponic system. This system could haveused fresh water that was rich in oxygen and minerals for the plants. Hydroponic systems need light. Inaddition to sunlight, hydroponic farms can use artificial lights. Instead of soil, hydroponic farms can usespecial material, such as charcoal and mixtures of chemicals, to feed the plants. And in addition to anatural climate, most hydroponic farms often use greenhouses. One advantage of hydroponics is thatdiseases and insects that travel through the soil are eliminated. Another advantage is that there are noweeds to pull out.Nutrition scientists at Cornell University in New York are experimenting with recipes that use thesehydroponic vegetables. The National Aeronautics and Space Agency (NASA) is paying for this nutritionresearch. The scientists are trying to develop new systems that will increase the flavor and the vitamincontent of the foods they grow. Some of the Cornell experiments in cooking are unusual. They makeimitation meat dishes, such as carrot drumsticks, made from carrots, peppers, onions, garlic, herbs, andbread crumbs, instead of chicken. They make dishes made from tofu and seitan (a wheat protein) insteadof meat. How do these unusual foods taste? The scientists invite a group of taste testers into theirlaboratories. Every week, 25 people came to taste five different dishes. So far, they have tested 200different recipes. The carrot drumstick dish was a hit. It rated an eight out of nine. Perhaps soon, peoplewill eat meals made from hydroponic vegetables that are truly out of this world.

【評論內容】你想要的東西不同的晚餐？嘗試一些太空食品。科學家正在試驗用的方式成長空間食品。科學家認為，在20年或30年中，宇航員將能夠生活在這個星球的宇宙殖民地。已經有許多科學家都住幾個月，國際空間站在地球上空高。它太昂貴，攜帶的糧食來養活人生活在宇宙殖民地。在空間殖民地的人將需要種植自己的食物。但如何才能使他們成長過程中沒有土壤和陽光的食物？今天，我們已經有水耕蔬菜。這些蔬菜可以沒有土壤中成長。食物可以在人工環境中成長。水耕科學並不是什麼新鮮事。許多作家認為，巴比倫空中花園實際上是一個大型的水培系統。該系統也可以使用，是植物中的氧氣和礦物質豐富的淡水。水培系統需要光。水耕農場除了在陽光下，可以使用人工照明。...
