Question

On the other side of the street stand more than 180 houses, _______are in poor condition now．

A．of which half	B．which half of
C．half of them	D．of them half

Answer 1

A

试题分析：考查定语从句，用的是名词+of which引导的定语从句，先行词是more than 180 houses，half of which=" half" of more than 180 horses ，句意：在街道的另一边有180多间房子，其中一半状况很差选A。
点评：定语从句关系词的考查，首先要确定从句是什么类型的从句，然后再分析关系词在从句中的成分，最后选择正确的词。要求考生具有一定的句子分析能力，和理解能力。定语从句中如果缺少名词+of+先行词，可用名词/代词+ of which/whom 引出定语从句,of which/whom 也可移至名词或代词前。
