It is very important for people to drink water in our daily life. Many people believe they need to drink eight glasses of water a day, or about two liters(升). But a recent report gives some different opinions.
Experts say people should drink according to their bodies. The report says most healthy people drink liquid(液体) when they feel thirsty. The report also gives some good suggestions. The experts say women should get about 2.7 liters of water daily. Men should get about 3.7 liters. But wait—in each case,that is more than eight glasses.
There is one important difference. The report does not tell people how many glasses of water to drink. In fact,the experts say it may be impossible to know how many glasses we need. This is because the daily want of water can include(包含) the water in foods. People do not get water only by forcing(强迫) themselves to drink some glasses every day. People also drink fruit juices, sodas and milk. They drink coffee and tea. These all contain water. Yet some also contain caffeine. This causes the body to expel(排出) more water. But the writers of the report say this does not mean the body loses too much water.

解析
21. 根据文章第二段“The experts say women should get about 2.7 liters of water daily.”可知，女性每天应摄入约2.7升水，故选B。
22. 根据最后一段“the daily want of water can include the water in foods. People do not get water only by forcing themselves to drink some glasses every day. People also drink fruit juices, sodas and milk.”可知，人们日常获取水分的途径不只是饮用白开水，还包括食物和其他饮品，故选C。
23. A选项：由第二段“The experts say women should get about 2.7 liters of water daily. Men should get about 3.7 liters.”可知男性每日需水量比女性多，表述正确；B选项：男性每日需水量是3.7升而非2.7升，表述错误；C选项：文章开头提到很多人认为要喝8杯水，但最新报告给出不同观点，说明并非所有人都需要喝8杯水，表述错误；D选项：最后一段提到含咖啡因的饮品会让身体排出更多水，但不会流失过多水分，表述错误。故选A。
24. 文章主要围绕“人们每天需要多少水”展开讨论，纠正了传统的8杯水观点，给出了专家的建议和水分来源的相关内容，所以最佳标题是C选项“How Much Water Do We Need?”。
25. 本文是一篇关于健康饮水的科普类文章，这类内容通常可以在科学杂志上读到，故选B。
