考研英语长难句分析

There is a great deal of this kind of nonsense in the medical journals which, when taken up by broadcasters and the lay press, generates both health scares and short-lived dietary enthusiasms.
这是2019年英语一翻译题型中的句子，在理解该句子时，其难点在于该句子出现了从句嵌套和状语从句省略的情况。“There is a great deal of this kind of nonsense in the medical journals”是整个句子的主干;which引导定语从句，修饰this kind of nonsense，该从句的主语为which，谓语为generates，宾语为both health scares and short-lived dietary enthusiasms，“when taken up by broadcasters and the lay press”是which引导的定语从句中的时间状语从句，嵌套在which和generates之间，增加了理解的难度。另外该时间状语从句中省略了主语和谓语的一部分，完整版本应为“when this kind of nonsense is taken by broadcasters and the lay press”。大家在长难句中遇到这种从句嵌套的情况，可以将嵌套的从句拿出来单独理解，出现省略情况的话，将其补充完整。整个句子可以这样理解“在医学期刊杂志上，有很多这样的废话。当广播公司和媒体报道这些无稽之谈时，那就会引起健康恐慌和短暂的饮食狂热。”
