【题目】实施南水北调工程主要目的是缓解我国水资源哪方面的问题（ ）

A. 东部多、西部少 B. 年际变化大 C. 季节分配不均匀 D. 地区分配不均匀

【答案】D

【解析】

南水北调工程完工后，将把长江、淮河、黄河、海河流域联结起来，统一调剂，构成我国水资源“四横三纵、南北调配、东西互济”的新格局，主要为了解决中国水资源分布严重不均的局面。

中国水资源地区分布不均衡，有必要兴建跨流域的调水工程，把水资源较丰富流域的水调至水资源紧缺的流域，以弥补缺水地区的用水不足。近几十年来，中国进行了多项跨流域调水工程。目前正在兴建的南水北调工程，属于中国最大规模的跨流域水资源综合开发利用工程。工程建成后，将把长江流域富余的水调入缺水的华北、西北地区。故选D。

【题目】Research says that husbands do not do their fair share of work around the house.A study from an American university says that men seldom do the same share of housework.Researchers interviewed 182 working couples who became first－time parents.Both husbands and wives worked almost the same number of hours in full－time jobs.However，men did five hours a week less housework than women after their baby was born..
