Question

6．有些人直到失去健康才意识到健康的重要性．（lose）
Some people won't realize the importance of their healthuntil they have lost it/until they lose it/their health．

Answer 1

分析 until they have lost it/until they lose it/their health

解答 答案：until they have lost it/until they lose it/their health
根据所给汉语意思"有些人直到失去健康才意识到健康的重要性"以及主句Some people won't realize the importance of their health为否定句，可知用not…until来表达"直到…才"，故由until来引导时间状语从句，又知"失去"的英文表达为lose，为及物动词，可直接跟名词，故失去健康可译为"lose their health"或用it代指上文提到的不可数名词their health，再根据主句是一般将来时由until引导的时间状语从句可以用现在完成时或一般现在时表将来，现在完成时的结构为have/has+动词的过去分词，主语为they第三人称复数，用助动词have，lose的过去分词为lost，在一般现在时中主语为they第三人称复数，谓语动词用原形即lose，故译为until they have lost it/until they lose it/their health．

点评 做这类题时先分析所给汉语句子意思确定相关的词汇和句型，然后仔细推敲时态考虑人称和数的变化问题，最后核查大小写，标点符号，及单词的拼写是否正确等等．
