Question

The conference was held to discuss the effect that tourism has ________ the wildlife in the area.

A．in

B．on

C．at

D．with

Answer 1

B

试题分析：考查固定词组。本题实际上考查的的have an effect on…对…有影响；本题是把the effect提前做完先行词，that指代先行词作为has的宾语。句意：会议被举行来讨论旅游业对这个地区野生动物的影响。故B正确。
点评：固定词组have an effect on…对…有影响；本题是把the effect提前做完先行词，that指代先行词作为has的宾语。
