20．我想知道他在学习化学上是否遇到了困难．I wonder/want to know whether he has difficulty learning chemistry．．
分析 I wonder/want to know whether he has difficulty learning chemistry．
解答 答案：I wonder/want to know whether he has difficulty learning chemistry．．
首先分析句子的时态和结构：这是一个含有宾语从句的主从复合句，主句和从句都用一般现在时，主句是"我想知道"I wonder/want to know；从句"他在学习化学上是否遇到了困难"用一般现在时，"是否"是if 或whether，其中句式"做某事有困难"是have difficulty doing sth．，故答案是：I wonder/want to know whether he has difficulty learning chemistry．
点评 此题考查对整句话的翻译，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等容易出错的问题．
