of factors, ________ are beyond our control.

B. most of which
C. most of what
D. most of that
题目解答
答案
B. most of which
解析
步骤 1：分析句子结构
句子的主干是"The growing speed of a plant is influenced by a number of factors"，其中"are beyond our control"是修饰"factors"的定语从句。
步骤 2：确定关系代词
定语从句中缺少主语，且先行词是"factors"，因此需要一个关系代词来引导定语从句。关系代词"which"可以指代先行词"factors"，并在从句中作主语。
步骤 3：选择正确选项
选项A中的"them"是代词，不能引导定语从句；选项C中的"what"不能引导定语从句；选项D中的"that"不能用于非限制性定语从句。因此，正确答案是选项B。
