Question

He chose to write a letter with __________ he could express his feelings.

A．that

B．which

C．what

D．who

Answer 1

B

试题分析：句意：他选择写一封能用来表达他的感情的信。定语从句用来充当句中定语的成分，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 。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。关系代词在从句中作主语、宾语。但在下列情况下一般只用that而不用which ：
先行词本身是all , everything , something , nothing , anything等不定代词时， 先行词已有序数词或形容词的最高级或the last, the only等作定语时，先行词既有人又有物时。但是连接词前有介词只用which不用that，根据句意及结构，故选B。
