Question

______ to arrive at the school at 10.am this morning,they are looking forward to getting

together with us.
A.Schedule B.Scheduling C.Scheduled D.To schedule
请问为何选 C?

Answer 1

schedule 是动词，此句已有动词 they ARE looking forward to getting together with us.因此A 错误。
Scheduled to arrive at the school at 10a.m. this morning, they are looking forward to getting together with us. 过去计划的今天早上十点在学校集合 scheduled作为状语前置，是为了说明原委 修饰they are looking forward to getting together with us.
scheduling 和to schedule 则无法表达过去订的计划从而导致今天十点在学校集合且they are looking forward to getting together with us的结果。
因此a b d为错误选项

Answer 2

这是被动语态，他们被安排在早点10点到学校，
