题目

Now some women are spending a weekend at Mother’s Camp(营地). There, husbands and children are not allowed. Why would a woman want to take a vacation without her family?Some women say they need time to be alone. At Mother’s Camp a woman has room for herself. She can sleep, read or watch TV, and no one will bother her. No children will ask, “Mom, what’s for dinner?” No husband will say, “Oh, dear, I can’t find any clean socks.” In fact almost 50% of women in the United States work outside the home. Many of them work full-time and then come home for a second job—taking阅读图文材料,回答下列问题。 材料一  抽水蓄能电站是利用电力负荷低谷时的电能把下水库的水抽至上水库，在电力负荷高峰期再把上水库的水放至下水库发电的水电站。它可将电网负荷低时的多余电 能，转变为电网高峰时期的高价值电能,且宜为事故备用。 材料二  福建省仙游抽水蓄能电站（图7),首台机组预计将于2013年10月31日投入 商业运行，将建有集雨面积为4.0km2的上水库和集雨面积为17.2km2的下水库,上下水 库落差470多米。 (1)  分析抽水蓄能电站的建设条件。（10分） (2)  说明仙游抽水蓄能电站建设的意义。（10分）
