27、p,the loss was minimized.givingsufferingwhensurvivorsto helpwerefrightened答案及解析：【语篇解读】本文是一篇记叙文，作者讲述了一次可怕的地震经历。地震给人们的生命和财产造成了巨大的损害，但是人们团结一心，互帮互助，共同渡过难关。1Suddenly 考查副词。suddenly意为“立刻，马上”，放句首，修饰句子，作状语。2at 考查介词。句意为：刹那间，一切都在摇晃，似乎整个世界就要结束。at an end为固定搭配，意为“结束，终结”，at an end在句中不能单独作谓语，要与be动词连用。3were destroye
28、d 考查动词的语态、时态和主谓一致。句意为：数百万的砖房和许多水坝遭到破坏。砖房和水坝是被破坏的，结合上下文语境，要用一般过去时的被动语态。主语为数百万的砖房和许多水坝，故填were destroyed。4giving 考查非谓语动词。此处考查with的复合结构，其构成为：with宾语宾语补足语，reporters和give之间是主谓关系，因此用give的现在分词形式。5suffering 考查名词。被作定语的形容词extreme修饰，用名词形式。句意为：全国都被地震带来的破坏和灾民们极度的苦难所震惊。suffering为suffer的名词形式，意为“痛苦，苦难”。6when 考查连词。句意为
29、：当人们读到幸存者以“恭喜啊，你还活着。”来互相安慰时，都被感动了。7survivors 考查名词。survivor为动词survive的名词形式，由句意可知，幸存者是很多人，故用名词的复数形式。8to help 考查非谓语动词。句意为：因此他们不仅衷心地表达了他们的同情，而且还立刻组织起来帮助灾民。人们组织起来的目的是帮助灾民，to help在句中作目的状语。9were 考查主谓一致和时态。句意为：伤员被救出了，死者被埋葬了。the dead表示一类人，谓语动词要用复数形式，由上下文语境可知，要用一般过去时。10frightened 考查形容词。句意为：吓坏的幸存者被从废墟中挖出来了，住处、饮用水和电力也很快得到提供。frightened为形容词，作定语，修饰名词survivors。
