15．有些人就是不知道怎样节约能源．Some people just don't know how to save energy．．分析 Some people just don't know how to save energy．
解答 答案：Some people just don't know how to save energy．
根据汉语意思，此句是指一种客观事实，故用一般现在时即可；主语为"有些人"可表达为some people；"就是"可用副词just表达，放在主语后面谓语前面修饰谓语；由于是一般现在时态，主语为复数some people，"知道"know为实意动词，所以其否定式要借助于助动词do加not缩写为don't+动词原形构成，所以"不知道"表达为don't know构成主句的谓语；故主谓部分可表达为：Some people just don't know；其后的内容充当宾语；"怎样"指方式，应当用疑问词how，在英语中通常运用"特殊疑问词+to do（不定式）"的结构去作宾语；"节约能源"应用save energy，energy为不可数名词；故可表达为：how to save energy．故此句可完整表达为：Some people just don't know how to save energy．
点评 此题考查句子的翻译．应首先根据汉语意思确定出句子的主要结构，尤其是主谓宾；还有时态，固定用法及用词的准确．尤其注意对细节的把控．
