日語條件形過去式
A. 如果if引導的條件狀語從句主句是過去式,從句是什麼形態
if引導的條件狀語 主將從現
主句用 一般將來時態 從句用一般現在時態 表將來
He will come if you invite him
如果主句是 過去將來式,從句用一般過去時態 (建立在你的說法是正確的基礎上)
He would come if you invited him(這個感覺像虛擬語氣)
實際上 if 引導條件狀語從句, 表示如果,是沒發生的事情,就不能用過去時態
表過去已經發生的事情,只能是虛擬語氣
詳細情況可以看 條件句 和 虛擬語氣
望採納!
B. if引導的條件狀語從句主從語句能都是過去時嗎跟一般的從句一般現在時主句一般將來時的形式有什麼區
不可以。If條件句的幾種用法及區分見下
真實條件句真實條件句用於陳述語氣,假設的情況可能發生。表示將來時,主句是將來從句是現在,記住『主將從現』。
非真實條件句表示對將來的假想,是不可能發生的,如果對將來的虛擬,從句一般過去時。
需要多做些題目來鞏固。
如果有疑問可以給我發簡訊。
[解題過程]
一、真實條件句
真實條件句用於陳述語氣,假設的情況可能發生,其中 if 是如果的意思。
時態關系
句型: 條件從句 主句
一般現在時 shall/will + 動詞原形
If he comes, he will bring his violin.
注意:
1) 在真實條件句中,主句不能用be going to表示將來,該用shall, will.
(錯) If you leave now, you are never going to regret it.
(對) If you leave now, you will never regret it.
2) 表示真理時,主句謂語動詞便不用shall (will) +動詞原形,而直接用一般現在時的動詞形式。
二、非真實條件句
1)時態:可以表示過去,現在和將來的情況。它的基本特點是時態退後。
a. 同現在事實相反的假設。
句型 : 條件從句 主句
一般過去時 should( would) +動詞原形
If they were here, they would help you.
b. 表示於過去事實相反的假設。

含義:He did not come yesterday, so I did not tell him about it.

含義: He was ill and missed many lessons, so he did not make greater progress.
