问题 When a body is ______ in a fluid it apparently loses weight.

选项 A、displaced
B、indulged
C、dispersed
D、immersed

答案D

解析 动词辨义。这四个选项的词性都是动词,displace“移置;移位”,如:He displaced a bone in his knee in the crash with another player.(他在与另一名运动员相撞时膝部有一块骨头移位了。)indulge是指“(常与in连用)放任;沉溺”,如:His father sometimes indulges in a cigarette.(他的父亲有时喜欢抽一支烟。)disperse表示“使四下散开;驱散”,如:The police dispersed the crowd.(警察驱散群众。)immerse表示“(常与in连用)沉浸于;沉溺于”,如:The whole town was immersed in a festival atmosphere. (全镇沉浸在节日的气氛中。)根据句意,应该是物体被浸入水中,应该选D)。
