问题 The normal food______of man depend in part on the amount of external work he does.

选项 A、quantities
B、requirements
C、necessities
D、acquirements

答案B

解析 requirement"需要";quantity"量",做复数用时指"大量",相当于量词,如:large quantities of food"大量的食品",但不说food quantities;necessities"生活必需品";acquirements"学到的东西"。全句意为:"从某种意义上来说,人的正常食物需要量取决于他的体能消耗量(外部做出的功)。"
