     Astronauts aboard the space station celebrated a space first on Wednesday by drinking water that had

been recycled from their urine (尿), sweat and water got from air. They said "cheers" to NASA workers

on the ground.

     The urine recycling system is needed for astronaut stations on the moon and Mars. It also will save NASA

money because it won't have to ship up as much water to the station by space shuttle or cargo rocket.

Besides, it's important as the space station is about to expand from three people living on board to six.

     The recycling system had been brought up to the space station last November, but it couldn't be used until

samples (样品) were tested back on earth. So when it came time to actually drink up, NASA made a big deal

of it. The three-man crew stood holding their drinks and congratulated engineers in two NASA centers that

worked on the system.

     "This is something that had been the stuff of science fiction," American astronaut Michael Barratt said

before taking a small mouthful. The taste is worth trying.

     The new system takes the combined urine of the crew from the toilet and moves it to a big tank, where

the water is boiled off, and the vapor is collected. The rest of the urine is thrown away. Then the water vapor

is mixed with water from air, and then it goes through filters (过滤器). When six crew members are aboard,

it can make about six gallons from urine in about six hours.

     "Some people may find the idea of drinking recycled urine distasteful, but it is also done on earth, but with

a lot longer time between urine and the tap," said Marybeth Edeen, the space station's national lab manager.

     The technology NASA developed for this system has already been used for quick water purification after

the 2004 Asian tsunami.

陈光标——中国首善、正义人物、高调慈善倡导者。自汶川地震后，关于他积德行善的种种事迹，便时常见诸报端。2011年3月11日，他以个人名义向云南盈江地震灾区捐献20万元人民币。2011年8月16日，陈光标向井冈山、泰州黄桥革命老区等，捐赠款物价值总计3100万元。但众人对他的这种“高调慈善”行为一直颇有争议。近期，他在微博留言：“要送莫言豪宅”。此言一出，立刻引来一片议论，再次把陈光标的“高调慈善”推到了风口浪尖。有人认为做慈善就应该低调，“做好事不留名”是中 * * 的传统美德；但也有人认为“高调慈善”能激发大家一起做慈善热情。

小王毕业于某外语学院，3年前通过公务员录用考试，现在XX部作为公务员，正在工作，他的一位在异国定居的表哥给他来信，说已为他联系好一所大学，并争取了奖学金，让他辞掉工作，速去学习深造。经过反复考虑，小王终于下定决心辞掉工作出国留学。但他向所在单位提出申请时，有关部门的领导说小王工作时间不到可辞职的年限，不能批准。小王至此很想不通，认为辞职是公务员的权利，不批准是不对的。而他的同事却笑他不明国家公务员辞职制度。请谈谈你对此的看法。
