Both my father and mother _______ _________ journalist since 1980.
Both my father and mother _______ _________ journalist since 1980.
Both my father and mother _______ _________ journalist since 1980.
have been
Both my father and mother have been journalist since 1980.
have been .....因为后面有since 1980...要用现在完成时
have been.
since+时间点,表示动作自这个时间发生,维持至今,或者对现在有影响,所以要用现在完成时态。
又因为,both A and B是两个人,所以谓语动词要用复数形式。
1)since后加时间点要求用现在完成时,因此选择have/has done结构。
2)又因为句子的主语是both...and...结构,表示两者都,因此选择have done。
3)再者,自从1980以来是一个时间段,要求用延续性动词be,所以不能用become等短暂性动词。
补:你写的原句错误,journalist应为复数,加s....
