There are so many tall trees in the forest, ______ .

A．some of them measures 50 metres

B．some of which measuring 50 metres

C．some of them measuring 50 metres

D．some of which measures 50 metres

【回答】

C

【解析】

试题分析：句意：森林里有许多高树，其中一些树高达50米。这里若使用some of which表示非限制*定语从句，从句谓语动词应该是measure，因为主语是复数，而使用some of them属于*主格结构，在句中作状语，且some of them是measure的逻辑主语，应使用现在分词measuring，即C项。

考点：考查*主格结构

知识点：*主格结构 with的复合结构
