Question

目前，新冠病毒（COVID-19）仍然是个大问题，全世界的科学家都在寻找它的解决办法。（非限定性定语从句）(汉译英)

Answer

At present/Presently, COVID-19 is still a big problem, to which the scientists across the world are looking for the solution.

【解析】

考查“介词+关系代词”引导的非限定性定语从句和固定搭配。主句主语COVID-19，主句系动词is，主句表语a big problem，本非限制性定语从句为：which the scientists across the world are looking for the solution to，the solution to和先行词a big problem形成固定搭配（the solution to +sth.“某事的解决方法”），可把to提到关系代词前面，用“介词+关系代词”引导的非限定性定语从句，即：to which the scientists across the world are looking for the solution；固定搭配the solution to +sth.（某事的解决方法），look for…（寻找……）。再根据其他汉语提示，故翻译为：At present/Presently, COVID-19 is still a big problem, to which the scientists across the world are looking for the solution。
