问题 Astronauts are ______ all kinds of tests before they are actually sent up in a spacecraft.

选项 A、inclined to
B、subjected to
C、prone to
D、bound to

答案 B

解析 根据常识可知,空格处应填表“须经……的”之义的词,故subjected to“经受,经过……”符合题意,选B。be inclined to表示“倾向于……”,be prone to表示“易于……”。be bound to表示“负有义务的,受……约束的”,如:You are legally not bound to answer these questions.(在法律上你没有义务非回答这些问题不可。)
