A 是正確的.
for 3 days 可以用于現(xiàn)在完成時,也可以用于一般過去時.
從and he is now at home.可知 約翰現(xiàn)在已經(jīng)不在他叔叔家里,所以用 一般過去時.
如果 選 B has stayed ,現(xiàn)在完成時表示過去開始的動作一直持續(xù)到現(xiàn)在,即“他現(xiàn)在仍在叔叔家里”,與句意不相符.
john（ ）at his uncle's for 3 days and he is now at home.
john（ ）at his uncle's for 3 days and he is now at home.
A.stayed B.has stayed C.had stayed D.was staying
PS:已知答案是A（不會別瞎說）,求原因～
