They_____london for three days. A.have been in B.have gone into C.have been to D.has gone to
They_____london for three days.
A.have been in B.have gone into C.have been to D.has gone to
They_____london for three days. A.have been in B.have gone into C.have been to D.has gone to
正确答案：A （句意：他们在伦敦已有三天了.） have been to:表示“到过某地”；have gone to 表示“去了某地（人不在现场）”.
A,他们在伦敦已经3年了
have been to是已经去过，现在回来了。have gone to 是去了还没回来。(不能用于时间段)正如题目他们在那待了三天，所以用A，待了三天。
D 表示已经去了三天，还没回来，完成时表示已经
C是表示去了，回来了，不对，
A,b用发错乐 ，go to 固定用法
选D ，望采纳谢谢
