His technique has developed to the point __where_ he can help kill the latest computer virus going

问题描述:

His technique has developed to the point __where_ he can help kill the latest computer virus going
round the city.
我想问he can help kill the latest computer virus.这个句子主语,谓语是哪些看不懂拜托啦

这是where引导的定语从句,从句的主语是he,谓语是help宾语是kill the latest computer virus.
其中help do sth是固定搭配,表示帮助做某事.
最后面的going round the city是现在分词做伴随状语
