Question

【題目】The growing speed of a plant is influenced by a number of factors, _____ are beyond our control.

A. most of which B. most of them

C. most of what D. most of that

Answer 1

【答案】A

【解析】句意：植物的生長(zhǎng)速度受很多因素的影響，其中的大多數(shù)是不受我們控制的。先行詞為factors，和從句構(gòu)成完整的句子應(yīng)為most of the factors are beyond …，應(yīng)用引導(dǎo)詞which代替factors，故選A。
