go abroad 去国外 为什么不说 go (TO) abroad

abroad是副词,到国外,go abroad就是去国外 go abroad是去国外,go to Egypt是去埃及.为什么go 后有时跟to,有时却不跟? “to go abroad ”还是“going abroad” we may go abroad.go做去的时候是不及物动词,为什么不加to go for abroad 和 go abroad区别 In order to go abroad省略为to go abroad可以么? 怎么理解to go abroad是为了 He will go abroad to study______. have you ever been to go abroad Go abroad 同义词 急 用go abroad造句 go abroad=? can I go abroad
