阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
Do you want something different for dinner? Try some space food. Scientists are experimenting with ways to grow food in space. Scientists think that in 20 or 30 years, astronauts will be able to live in space colonies(聚居地)off the planet. It's too expensive to carry food to feed people living in space colonies. People in space colonies will need to grow food for themselves. But how can they grow food without soil and sunlight?
Today, we already have hydroponic(无土栽培)vegetables. These are vegetables you can grow without soil. This kind of food can grow in an artificial(人工的)environment. In addition to sunlight, hydroponic farms can use artificial lighting. Instead of soil, hydroponic farms can use special material, such as mixtures of chemicals, to feed the plants, and in addition to a natural climate, most hydroponic farms often use greenhouses. Farmers know how to grow a few kinds of hydroponic vegetables. In winter, when it is too old to grow vegetables outdoors, hydroponic farmers can grow such vegetables as lettuce, tomatoes, and cucumbers and many different herbs and spices. These products are in many supermarkets. However, in space, people will need to eat more than salad and spices. So scientists are learning how to grow hydroponic rice, beans, potatoes, and wheat. Scientists can even grow hydroponic melons and strawberries.
Nutrition(营养)scientists at Cornell University in New York State are experimenting with recipes (食谱)that use these hydroponic vegetables. The National Aeronautics and Space Agency(NASA)is paying for this nutrition research. Some of the Cornell experiments are unusual. They make imitation meat dishes, such as carrot drum sticks made from carrots, peppers, onions, garlic, herbs, and breadcrumbs instead of chicken. They make dishes made from tofu and seitan(a wheat protein(蛋白质))instead of meat. How do these unusual foods taste? The scientists invite a group of taste testers into their laboratories. Every week, twenty－five people come to taste five different dishes. So far, they have tested 200 different recipes. The carrot drum stick dish was a hit. It rated an 8 out of 9. Perhaps soon, people will eat meals made from hydroponic vegetables that are truly out of this world.
1．It takes too much ________ to bring food to space colonies.
[ ]
2．To grow hydroponic vegetables, you need ________.
[ ]
A．chemicals to feed the plants
B．sunlight and warm weather
C．soil to grow the plants in
D．nothing to feed the plants
3．You can find hydroponic vegetables in ________.
[ ]
4．Scientists are experimenting with recipes that use ________.
[ ]
A．vegetables instead of meat

1．B 从原文第一段“It's too expensive to carry food to feed people living in space colonies．”可知本题正确答案为B。 2．A 根据原文第二段中的“Instead of soil，hydroponic farms can use special material，such as mixtures of chemicals，to feed the plants．”可知A项正确。其他几项均与上句意义不符。 3．C 从原文第二段中的“These products are in many supermarkets．”可做出正确判断。此题容易误选A项。科学家在太空实验室中是研究无土栽培蔬菜的食谱。 4．A 根据原文最后一段第一句可做出正确判断。 |
