Daylight Saving was first introduced during World War I in Australia. During the world wars, DST was used for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943.In 1967, Tasmania experienced a drought（干旱）. The State Government introduced one hour of daylight saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South Wales, South Australia and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989.Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics or festivals（节日）. For example, in 1992, Tasmania extended（延长）daylight saving by an extra month while South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving plans were made during the Sydney 2000 Olympic Games.The differences in daylight saving in Australia continue to cause serious problems in transport and many other social activities. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the east coast cause major differences, especially for the broadcasters of national radio and television.68. Daylight Saving Time was introduced in Tasmania _______________.A. to stop the drought in 1967       B. to support government officialsC. to pass a special law in the state   D. to save water and electricity69.

请教什么是Daylight Saving Time
daylight saving time就是“夏时制”夏令时,又称“日光节约时制”（Daylight Saving Time）,是一种为节约能源而人为规定地方时间的制度,在这一制度实行期间所采用的统一时间称为“夏令时”.一般在天亮早的夏季人为将时间提前一小时,可以使人早起早睡,减少照明量,以充分利用光照资源,从而节约照明用电.各个采纳夏时制的国家具体规定不同.目前全世界有近110个国家每年要实行夏令时. 据说最早建议使用夏时制的是本杰明·富兰克林,他在任美国驻法国大使期间,由于习惯于当时美国农村贵族的早睡早起生活,早上散步时看到法国人10点才起床,夜生活过到深夜.于是他在1784年的一期《巴黎杂志》上发表了一篇文章,说法国人的生活习惯浪费了大好的阳光,建议法国人早睡早起,说每年可以节约6千4百万磅蜡烛.但他当时并没有建议实行夏时制,因为当时根本还没有统一的时区划分.不过夏时制在英语里就是“节约阳光时间”的意思. 直到1907年,一位英国建筑师威廉·维莱特（William Willett）才正式向英国议会提出夏时制的设想,主要是为了节省能源和提供更多的时间用来训练士兵,但议会经过辩论没有采纳. 1916年,德国首先实行夏时制,英国因为怕德国会从中得到更大的效益,因此紧跟着也采取了夏时制,夏时制节约了约15%的煤气和电力,但为了弥补损失,电力和煤气公司也将价格提高了15%.法国不久也效仿实行.1917年,俄罗斯第一次实行了夏令时,但直到1981年才成为一项经常性的制度.1918年,参加了第一次世界大战的美国也实行了夏时制,但战后立即取消了. 1942年,第二次世界大战期间,美国又实行了夏时制,1945年战争结束后取消.1966年,美国重新实行夏时制.欧洲大部分国家从1976年,即第四次中东战争导致首次石油危机3年后（1973年）开始实行夏时制. 根据联合国欧洲经济委员会的建议,从1996年起夏令时的有效期推迟到10月份的最后一个星期日.daylight saving time
