she has just arrived ------USA.用from还是 in?
问题描述：
she has just arrived ------USA.用from还是 in?
答
she has just arrived ------USA.用from还是 in
用in
通常达到一个国家或大城市都用in
小地方用at
from是表示从哪个地方来,和come连用
例：I come from USA我来自美国我在书上看到的，就是用的FROM,不知道为什么？还有一个句子，where has she come from?为什么用has 呢？你是说你看到的句子是：she has just arrived from USA.这种也是正确的译：他刚从美国来，（更多用于说话人在目的地）.例：Will Tom arrive from Moscow the week after next?汤姆再下个星期会从莫斯科来吗?。where has she come from?：这句话是很标准的：come是过去分词，和has构成第三称为主语的“现在完成时”）
