解析

试题分析： 本文叙述了澳大利亚23日遭遇了70年以来最猛烈的沙尘暴袭击，一些城市均被笼罩在红色沙暴中。澳大利亚卫生部门发出健康警报，要求儿童、老人，以及罹患哮喘和其他呼吸系统疾病的患者待在室内，不要外出。出行的人们都戴着面罩，部分学校关闭，体育活动也被叫停。据悉，此次沙尘源于澳大利亚中部干旱地区，当天悉尼的空气污染程度为平日的1500倍，是迄今为止最高的污染指数纪录。悉尼机场的国内和国际航班均延误3到6小时，部分国际航班因为能见度太低而被取消。
小题1:根据Commuters used face masks，originally intended to protect them from the spread of swine flu,人们戴口罩主要用来防止猪流感，故用Protecting people from the spread of swine flu。
小题2:根据Residents from Sydney in New South Wales to Canberra inland and towns in southern Queensland awoke to a red sky 人们醒来后发现的，所以应该是在早晨，故用In the morning。
小题3:根据national carrier可知航空公司，故用A flight company/An airline.
小题4:根据The sand storm，which measured more than 310 miles wide and 620 miles long， was caused by dust clouds blowing east from Australia’s dry places主要叙述的是风暴的原因，故用The cause of the dust/sand storm。
