拓展10
【答案】 CBADC CBBAC
【解析】 (1)句意：乘船旅行有时候很危险。轮船有时候在远离大陆的地方沉没。sink下沉，主语ships是复数，
(2)句意：如果另外一艘轮船没有来救他们，他们就没有足够的食物和水，他们就会死。ill adj生病的；die v死；dead adj死的； sick adj不舒服的。根据句意可知选B。
(3)句意：大部分人认为我们一定不要喝海水。他们认为如果我们喝了，我们因为海水里面的盐而会很难受。此处指前文中的drink sea water喝海水，为了避免重复，用do代替，因为在if从句中用一般现在时表示一般将来，
(4)句意：因为海水里面的盐。because引导从句；as引导从句；for表“因为”时引导从句，because of后跟名词，all the salt in the water是名词短语，
(5)句意：他认为人们可以通过喝海水，吃小鱼，海里面的动植物来活着。by+动词-ing，通过某种方式。and前后是平行结构，根据后面的eating可知选C。
(6)句意：在1953年10月19日，他乘坐一艘小船横渡大西洋。across是介词；cross是动词。to+动词原形 构成不定式，表示目的，
(7)句意：他也抓鱼，鱼的体内有水。根据常识可知选B。
(8)句意：他从海里捞小植物，这些给他更多的食物。由句中的逗号可知这是一个非限制性定语从句，先行词是small plants，故用which，
(9)句意：Bombard博士变得冷、疲劳，非常难受，但是过了65天后他仍然活着。cold冷的；warm温暖的；cool凉快的；hot 热的。根据前文的时间19 October可知是寒冷的，另外根据后面的tired和ill的感情色彩可以排除BCD，
(10)句意：他失去了20千克的体重，但是他向人们展示了人们可以靠海水和海洋里面动植物生活。live on以……为生。
