情态动词的用法Ⅱ【课文解析】1
WhatwereyoudoingwhentheUFOarrived
(1)这是一个含有时间状语从句的主从复合句,主句为whatwereyoudoing,从句是由连词when引导的时间状语从句,说明主句动作发生的时间
ex:Thestudentsweretalkingwhentheteachercamein
IwaswatchingTVwhenthebellrang
WhenIgothome,mymotherwascooking
(2)arrive是不及物动词,如果表示到达某地,则用arrivein/at…,相当于getto…或reach
需要注意的是,reach是及物动词,必须跟地点
getto跟地点名词,如果是地点副词,则省略介词
如:gethere/home/there
