问题 The heart is an important organ of circulation ______ function is to pump. blood to all parts of the body.

选项 A、which
B、whose
C、of it
D、its

答案B

解析 B句意：心脏是血液循环的器官，它的功能是把血液输送到身体的各个器官。该题考查的是定语从句的用法。选项A的which应该在定语从句中担任一定的成分，但空格之后的句子是主系表结构，主谓成分已经很齐全，所以不适合。选项C不能使原句的结构成立。假如把its放在空格处，在其前应该加句号将两句分开。选项B的whose作关系代词时，既可指人，也可指物，因此是正确答案。
