一个英语句子的部分成分分析
Hypotheses arise by guesswork or by inspiration ,but having been formulated they can and must be tasted rigorously ,using the appropriate methodology.(but having been formulated they can and must be tasted rigorously和,using the appropriate methodology各是句子的什么成分?为什么要用逗号隔开)
Hypotheses 是主语 arise是谓语 by guesswork or by inspiration是状语
后面是并列句,but是并列连词 having been formulated 是并列句的状语 they是主语 can and must be tasted rigorously 是谓语, using the appropriate methodology是现在分词短语作状语
分词作状语 一般要用逗号隔开)
再问: rigorously 是谓语的一部分吗?不是表语吗?
