Question

【题目】Scientists are making great efforts to develop new drugs to avoid the situation ____ the drug has more or less some side effect which will effect other organs.

A.whenB.thatC.whichD.where

Answer 1

【答案】D

【解析】

考查定语从句。句意：科学家们正在努力开发新药，以避免药物或多或少会对其他器官产生副作用的情况。此处为定语从句，先行词为抽象名词situation，表示“到了某种情况”，从句中缺少地点状语，故D项正确。
