分析 本文主要讲述了于3月8日,0:41分,从马来西亚的吉隆坡起飞的那架波音777飞机的失踪之谜;此次航班上载有239人,目的地是北京,但它始终却没能到达目的地;马来西亚民航局局长阿扎鲁丁(Azharuddin AbdulRahman)认为,它的消失是一个"史无前例的"航空之谜;它没有坠机的迹象,在它大约起飞两小时后,空中交管突然与其失联;当天天气晴朗,飞行员没有打求救电话,并且在飞机最后一次接触的区域里也没有发现碎片;此外,据波音公司8月份的报告称,飞机坠毁通常是发生在起飞或降落时,只有百分之九的致命事故发生在飞机处在平稳行进的高度时.
解答 答案:
41.Its 考查形容词性的物主代词 根据上文可知,这里指的应是:于3月8日,0:41分,从马来西亚的最大城市吉隆坡起飞的那架波音777飞机的目的地;故用Its
42.leaving 考查现在分词 本句的意思是:但航班始终没有到达,只留下了机上乘客的朋友和亲人们在那里哭泣和担心;此处在句中作结果状语,由于动词leave与其逻辑主语 the flight 构成了主谓关系;故用现在分词leaving
43.on 考查固定短语 固定短语on board意为:在船[火车,飞机,汽车]上;故用on
44.were…searching 考查时态 本句的意思是:包括中国,越南,美国,新加坡以及菲律宾在内的这些国家仍在寻找着失踪的飞机;此处表示当时正在进行的动作,故用过去进行时were…searching
45.disappearance 考查词类转换以及名词 此处与形容词性的物主代词Its一起在句中作主语;故用disappear(动词)的名词形式disappearance
46.a 考查冠词 由于此处的crash为可数名词,故填a
47.and 考查并列连词 本句的意思是:飞行员没有打求救电话,并且在飞机最后一次接触的区域里也没有发现碎片;由于空缺处的前后两句是并列关系;故用and
48.where 考查关系副词 本句是定语从句;由于先行词area 在该从句中作地点状语,意为:在飞机最后一次接触的区域里;故填where
49.typically 考查副词 此处用来修饰动词 occur;故用副词typically
50.when 考查从属连词 本句的意思是:据波音公司8月份的报告称,只有百分之九的致命事故发生在飞机处在平稳行进的高度时;此处用来引导时间状语从句;故用when
