優(yōu)質(zhì)解答
因?yàn)楸揪涫敲枋鲎詮乃齻z在上海相遇到現(xiàn)在是三年,it is three years 若用A就與題意不負(fù)為什么？因?yàn)楸揪薜闹骶涫顷愂鼍?，要用A的話是這樣才對(duì)they have been met in shanghai since three years.have been met 不就變成被動(dòng)語(yǔ)態(tài)了嗎？since three years不用加ago嗎？剛太激動(dòng)多打個(gè)been 沒有ago,since加一段時(shí)間是現(xiàn)完時(shí)，一段時(shí)間加ago是一過時(shí)。since 和ago永遠(yuǎn)不能同時(shí)用(⊙o⊙)哦
