explanation: "delivery" must be "ordered" and then "paid". "order", "payment", and "delivery" are arranged in time order. the subject of "delivery" is different from "order" and "payment". to "deliver" a package, you must first "send" and then "receive"; "send", "receive", "delivery" should be done in time order. the subjects of "sending", "receiving" and "delivering" are different. a "contribution" must first be "write" and then "revise"; "write", "revise"and "submit" should be done in time order. the subjects of "writing", "revising", and "submitting" are the same. there is no obvious chronological order between "fertilizing" and "sowing", and the subjects of "fertilizing" and "sowing" are the same. "marking" must first "review" and then "exam", the time of "review", "examination", and "marking" must follow each other. the main body of "marking" is different from "review" and "examination".
