A violin was up for auction（拍卖）one day. The violin was very old. It didn't look like it was even playable. The auctioneer didn't feel like it was worth his time. But he still held it up with a smile.
"Who'll start the bidding for the violin " he shouted.
"One dollar One dollar. Then, two! Only two Two dollars, and who'll make it three Three dollars, once；three dollars, twice；going for three ..."
"Wait a moment!" A gray-haired man came forward. He said, "May I play a song for you "
The people in the hall gave him little applause as he picked up the violin. But when he started playing, the audience enjoyed the music, for the man played quite beautifully.
Then, he stopped playing. The auctioneer held the violin up again and said, "Who would like to bid on the violin "
"One thousand dollars! Who'll make it two Two thousand! And who'll make it three Three thousand, once；three thousand, twice；going and gone," he said.

B.驱护舰受到的浮力和停在甲板上的直升机对驱护舰的压力是一对平衡力
C.柴油机效率高，是因为柴油的热值大
D.柴油机是利用内能做功的机器
【答案】D
【解析】以驱护舰为参照物，货物和驱护舰之间的位置没有发生变化，货物是静止的，A错误；驱护舰受到的浮力等于驱护舰及其上面所有物体的总重力，甲板上的直升机对驱护舰的压力等于直升机的重力，这两个力大小不相等，所以不是一对平衡力，B错误；柴油机的效率高，是因为柴油机在压缩冲程中，压缩的程度比较大，燃料燃烧较充分，转化成的有用功更多，而不是因为柴油的热值大，C错误；柴油机工作时通过燃料的燃烧得到内能，再通过高温燃气对活塞做功，把内能转化为机械能，是利用内能做功的机器，D正确。
6、四冲程汽油机工作时，将内能转化为机械能的冲程是（ ）
A. 吸气冲程
