句子为 they were at their happiest whilst playing soccer
以下是我对句子的分析:(1)当whilst为连词成分时用法于while相同,那么原句为they were at their happiest whilst (they were) playing soccer,(they were 可以省略),那句子意思为他们最开心的是当他们踢足球的时候。
(2)当whilst为名词成分,其意思为一会儿、一段时间,此时句意为他们踢足球的时候最开心了,根据此句意我判断playing soccer 为伴随状语,对此我很纠结它是做伴随状语还是后置定语。
对于第一和第二种分析中whilst的用法我这样分析是否正确,请指出
