正确答案是D没有问题 The best way to do sth is to do sth

这里after pounding做什么成份呢? 其它题目里见过几次after doing 用法各异 请问这里是什么成份? 谢谢

我也有疑问，C: The best way to extract the flavor from saffron threads is soaking them in liquid after being pounded

详解中说after being pounded介系词词组修饰soaking的逻辑主语(可想象为某人)或主句主词the best way皆不符逻辑。

但为什么after being pounded不能修饰them呢？

请NN解释啊~~
