I hate people talk too much but do little.
A. who
B. whose
C. which
D. when

(答案→)A. whoB. whoseC. whichD. when解析：句意：我讨厌说得多做得少的人。定语从句用来充当句中定语的主谓结构，被修饰的名词叫先行词，连接主从句的是关系词。关系词分：1关系代词：who , whom , whose , which , that 。在句中作主语（who,which , that）在句中做宾语(whom,who)，在句中作定语（whose）。2关系副词：where,when why 等。一般的who 用于指代人的先行词，which 用来指代物的先行词，that既可指认又可指物。该句的先行词是people,故选A.
