1.The former has been put down to social effects, such as a strongtradition of valuing education.
2.The latter was seen as a consequence of genetic isolation.
疑问：
1.个人理解1句还原主动sbhas putthe formerdown to socialeffects。原句被动 to social effects 请问是变成了主语补足语还是状语呢？
2.同理2句的as a consequence of...是主语补足语还是状语呢？
麻烦老师解答一下我的疑惑，十分感谢！
1.The former has been put down to social effects, such as a strong tradition of valuing education.
2.The latter was seen as a consequence of genetic isolation.
句1，无论句子是主动语态，或是被动语态，黑体部分都是状语，是广义的地址状语，因为 put down...to... 成为固定搭配，意为 “把......归结于”，所以to social effects 为必具性状语，不可或缺。没有宾语补足语或主语补足语之说。
句2，黑体部分是主语补足语；句子在主动语态时，是宾语补足语。
