单选题There was an engineer who had an exceptional gift for fixing all mechanical (机械的) things. After serving his company heart and soul for over 25 years, he happily retired(退休). Several years later his company telephoned him regarding a seemingly impossible problem they were having with one of their multi-million-dollar machines. They had tried everything and everyone else to get the machine fixed, but no help. In desperation (绝望), they called on the retired engineer who had solved so many of their problems in the past. The engineer unwillingly took the challenge. He spent a day studying the huge machine. At the end of the day he marked a small X in chalk on a particular part of the machine and proudly stated, "This is where your problem is.” Tile part was replaced and the machine worked perfectly again. The company received a bill for $ 20,001 from the engineer for his service. They told him to make a list of his charges. The engineer answered briefly: One chalk mark... $ 1 Knowing where to put it... $ 20,000.

单选题D Plants need green leaves to make food. A plant needs sunlight and carbon dioxide (二氧化碳) from the air for making food and it also needs water and salts from the soil to make food too. There are certain cells (细胞) in the leaves which change carbon dioxide and water into sugar. To do this the cells need energy, which they get from the sunlight. Green leaves make food for the whole plant. A red leaf can make food too because under the red coloring of the leaf there are food-making cells. There are no leaves that are completely yellow, for they can't make food. The plant makes sugar for its food. In sunlight green leaves make a lot of sugar. The veins (叶脉) can't carry all this sugar away, so the leaves change the sugar into starch (淀粉), which is kept and so stored in the leaves. At night, the starch change back to sugar. It is then carried away from the leaves. Some of the sugar is used as food by the plant while the rest is stored as starch. In some plants, food is stored in the roots; in others it is stored in the stem and in leaves, fruits and seeds.
