2019-2020年人教版高中英語選修6 Unit 1 Art period 2 教案2 1. Presentation Purpose: To revise the usage of the subjunctive mood with Ss. 所述情況 從句 主句 與現(xiàn)在事實(shí)相反 If+主語+動詞過去式 主語 + would/could/might/should+ （be 動詞用 were） 動詞原形 與過去事實(shí)相反 If+主語+動詞過去完成式 主語 + would/could/might/should+ have + 過去分詞 與將來事實(shí)相反 ① if+主語+動詞過去式 主語 + would/could/might/should+ ② if+主語+were to + 動詞原形 動詞原形 ③ if+主語+should+動詞原形 此表中需要注意幾點(diǎn)： (1) be 動詞在表示與現(xiàn)在事實(shí)相反的從句中一般用 were.在非正式情況先，第一、第三人稱 后偶爾也用 was. 如： If he were you, he would go at once. (2) 主句中的 should 通常用于第一人稱，would，could 以及 might 可以用于各種人稱。 (3) 在表示與將來事實(shí)相反的條件句中，只能用 should，而不能用 would, could, might 等。 如：If it should rain tomorrow, we would not go camping. (should rain 也可以用 rained, were to rain 代替)。 (4) 當(dāng)條件狀語從句表示的行為和主句表示的行為所發(fā)生的時間不一致時，被稱為“錯綜時 間條件句”，動詞的形式要分別根據(jù)它所表示的不同時間做相應(yīng)的調(diào)整。如： If you had followed my advice, you would be better now. 2.
