英語語法 虛擬語氣：非真實條件句.should 是什么?
第一個should + have + done
You should have seen his face.(原句)這句是省略了從句,沒錯吧.
If the steamer should have left port at noon,it will be passing through the canal now.（原句）
不應該是:If the steamer had left port at noon,it would have been passing through the canal.
或者：If the steamer left port at noon,it will be passing through the canal now.
請指教上兩句對嗎?原句中的should have 那么最上頭那句也不理解了.
第二個 should + be
If you should see Celia,give her my best wishes.(原句)
不應該是：If you saw Celia,give her my best wishes.
第三個 作表語
They suggested that we should meet at the station.(原句)請問有點像had better的感覺,沒有時間的概念,也是非真實條件句嗎?
suggest有這個短語呀 那么這樣呢
It is desirable that everything should be ready by five o'clock.(原句)
