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.
What is this passage mainly about?
(A)Innovative food for the future.
(B)How to grow vegetables well.
(C)Advantages of hydroponic systems.
(D)Experiments with new recipes that use vegetables.
