Hegottohisfeet[asifbystandinghemeanttobegincoreecting(whatcouldnotbecorrected)]andthen(heknewthefoolishnessofthisinstentionandbecamemoreawkwardthanever)
这句句子比较复杂,先要弄清楚从句的位置,然后剩下的就是主句.中括号里的是由asif引导的状语从句,里面的小括号里是套着的宾语从句,andthen的前后是两个并列的主句.
如果去掉从句不看的话,这句句子就是hegottohisfeet是一句,andthenheknewthefollishnessofthisintentionandbecamemoreawkwardthanever.
主语就是he,谓语分别是gotto,knew和became,宾语就是hisfeet,thefollishnessofthisintention.因为became是系动词,所以became的后面跟的一定是表语,所以,moreawkwardthanever就是表语;
因为是状语从句,所以整个从句就是着个句子的状语部分.
