在完成時(shí)的用法：
1、表示過去發(fā)生的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果.常與already, just, ever, never, before等詞連用. 如:
She has never read this novel.他從未讀過這本小說.(他對(duì)小說的內(nèi)容不了解)
2、表示 "過去的動(dòng)作"一直延續(xù)到現(xiàn)在并有可能繼續(xù)延續(xù)下去. 常與for (后跟段時(shí)間)或since (后跟點(diǎn)時(shí)間)等連用.如:
I have been a member of the Party for 10 years.
I have been a member of the Party since 10 years ago.
注：在有for 和since 引導(dǎo)時(shí)間狀語的句子中不能用短暫性動(dòng)詞，應(yīng)用與之相應(yīng)的表示狀態(tài)的詞。如：
He has died for 3 years.(F)
He has been dead for 3 years.(T)
注意：①現(xiàn)在完成時(shí)不能和表示明確的過去時(shí)間連用。如：in 1998, last morning等
②have/has been to 表示"去過"（去了又回來了）
have/has gone to 表示"去過"（去了沒回來了）
如：Where has she gone?(句中所指的人不在)
Where has she been?(句中作指的人在)
例題解析：舉一反三，學(xué)的更輕松！
--How long ______ he ______ a fever?
--- Ever since last night.
A. have, got B. have , had C. have, caught D. did, have
