if there had not been a hard layer of rock beneath the soil,they would have completed the job in a hours.這句話我有2處不懂.
if there had not been a hard layer of rock beneath the soil,they would have completed the job in a hours.這句話我有2處不懂.
1.if there had not been這里的had是作“有”的意思嗎 had not 是否定形式“沒有”的意思?如果這樣的那后面為什么要加been呢?直接if there had not a hard layer of rock beneath the soil這樣不就可以了嗎?
2.they would have completed the job in a hours,這句話我沒能理解,應(yīng)該怎么劃分呢?這里的have什么意思呢?是什么用法?

優(yōu)質(zhì)解答
這是虛擬語氣的用法,if 引導(dǎo)的句子有真實條件句和非真實條件句,非真實條件句就是虛擬語氣!1 與現(xiàn)在事實相反 if + 主語+過去式,主句中：主語+ would/could/might/should + V (原形)2 與過去事實相反if + 主語+過去完...if引導(dǎo)的句子是沒有現(xiàn)在時態(tài)和現(xiàn)在完成時態(tài)，只有過去式和過去完成時態(tài)是嗎？ 還有與將來事實相反 這個例子我看不太懂 你能幫我舉個英語例子嗎？ 非常感謝與現(xiàn)在事實相反 ： If I were you , I would take his advice. 如果我是你，我就會采用他的建議。 與過去事實相反 ：If you had taken my advice , youwould nothave failedinthe exam. 如果你聽了我的建議，你就會考試就能及格了。 與將來事實相反 ：If you came tomorrow, we would have the meeting.如果你明天來我們就開會。 If it were to rain tomorrow, the sports meeting would be put off. 如果明天下雨，運動會將會被延期。If he should not come tomorrow ,we should put off the meeting till mext Monday. 如果他明天不來，我們將把會議延至下周一。 注意！虛擬句中，be 動詞常用were，過去式不用was
