Question

【题目】Convenient ______ plastic bags are for people, they will cause white pollution.

A. as B. although

C. since D. while

Answer 1

【答案】A

【解析】

考查形式倒装句。句意：对人们来说尽管塑料袋很方便，但它们会导致白色污染。句中形式倒装句“Convenient as plastic bags are for people”相当于让步状语从句“Although plastic bags are convenient for people”，故A项正确。
