I'd go with you to the trip ,but I ___no time.本題出自何處
此題的第一種語境應(yīng)該是：If I had time now,(與現(xiàn)在的事實(shí)不相符的虛擬條件句)I would go with you,but I have no time now(現(xiàn)在的真實(shí)情況)，所以，我認(rèn)為還是應(yīng)該選擇have.
第二種語境應(yīng)該是if I had had time then,(與過去事實(shí)不相符的虛擬條件句)I would have gone with you on the trip,but I had no time then.（過去的事實(shí)）答案選擇had.
我可以認(rèn)同I'd是I would 的縮寫 would是will的過去式
此舉的意思是：當(dāng)時我愿意和你一起去旅游，但是我沒有時間。是指當(dāng)時沒有時間，不是現(xiàn)在。所以應(yīng)該用had 但是上面兩種理解都有可能吧！
