分析 医学研究者们痛苦的意识到,对于许多问题来说,直到今天他们还没有找到答案.
解答 答案:to which they haven't found
解析:根据中文及所给英文题干可知,横线及其后的部分为定语从句;定语从句的先行词为problems,根据the answer(s) to the problem(s)"问题的答案"这一固定搭配可知problems在定语从句中作介词to的宾语,故定语从句只能使用关系代词which引导(不可使用that,因为有介词).又根据中文"直到今天还没…"可知,定语的时态为现在完成时.综上,本题答案为:to which they haven't found.
点评 本题考查句子翻译,做此类题目时一定要根据中文及英文题干确定需要翻译的成分,再找出与之对应的英文并考虑各成分是否有形式的改变.
