4.Some of these causes are completely reasonable results of social needs. Others are reasonable consequences of particular advances in science being to some extent self-accelerating.
Some of these causes are reasonable results, Others are consequences of advances
主语是some of these causes,实际的主语就是some,不过谓语是单数还是复数则取决于of后面的成分是单数还是复数。being to是定语从句的分句结构,意为属于。
在这些原因中,有些完全是自然而然地来自社会需求,另一些则是由于科学在一定程度上自我加速而产生的某些特定发展的必然结果。
这个翻译比较简单,注意being to的翻译即可。
5.This trend began during the Second World War, when several governments came to the conclusion that the specific demands that a government wants to make of its scientific establishment cannot generally be foreseen in detail.
This trend began during , when,that
1)有套和从句。这个句子实际上是This trend began.其余的成分都是在起修饰和限定作用。在分析长难句时一定要注意找出句子的主干,关键是确定句子的主语和谓语,只有这样才不会被众多的修饰成分所迷惑。
2)When引导的是时间状语从句。第一个that引导的是修饰conclusion的定语从句,第二个that引导的是修饰demands的定语从句,wants前省略了which,是引导的修饰a government的主语从句。
