The festival brings families back together . 这里bring back可以看作是动词+副词的动词词组做谓语 然后families是宾语,together是状语修饰brings families back 也可以把brings看做谓语 back看做宾补 together看做状语
This (主语)would prevent (谓语)you(宾语) from the infection of bacteria(状语). I (主语)would ask (谓语)my superior (宾语)for instructions(状语). We(主语) should make (谓语)the play attractive (宾语)for the audiences(状语). 请采纳。
