表示“到达”get to = reach = arrive in/at 后面接表示地点的名词.
eg.When did you get to Shanghai?When did you reach Shanghai?
When did you arrive in Shanghai?你是什么时候到达上海的?
但三组词有区别:
reach可以接表示地点的副词,如：here,there,home等.
get to后面接这些副词,要去掉to arrive in/at后面接地点副词,应去掉in/at
He reached home at half past eight last night.
=He got there at half past eight last night.
=He arrived there at half past eight last night.
应注意,如果动词之后不指到达什么地方时,一般只用arrive,不用reach和get to
eg.When we arrived,it was raining hard.当我们到达时,雨正下得很大.
