1什麼是狀語從句
狀語從句 (Adverbial Clause) 狀語從句指句子用作狀語時,起副詞作用的句子。它可以修飾謂語、非謂語動詞、定語、狀語或整個句子。根據其作用可分為時間、地點、原因、條件、目的、結果、讓步、方式和比較等從句。狀語從句一般由連詞(從屬連詞)引導,也可以由詞組引起。從句位於句首或句中時通常用逗號與主句隔開,位於句尾時可以不用逗號隔開。
2狀語從句考點分析:
1. 狀語從句雖然有完整的主謂結構,卻是不能獨立的從句。
2. 狀語從句它由從屬連詞引導成為整個句子一個不可缺少的部分。
3. 考查的熱點有條件、時間、地點、讓步等狀語從句的連接詞詞義辨析.
4. 動詞的時態呼應、狀語從句的省略等。
5. 題乾結構呈交叉和綜合特徵,選項設計多從定語從句和名詞性從句的角度進行思維干擾。
3狀語從句時態特點
一般情況下,時間和條件狀語從句的謂語動詞一般用“一般現在時”表示“一般將來時”,用“現在完成時”表示“將來完成時”。例如:
I will call you as soon as I arrive in Beijing. 我到北京就將給你打電話。
(這是由as soon as引導的時間狀語從句,從句中的謂語動詞arrive是一般現在時,表示一般將來時,絕不可用will arrive)
As soon as I have finished this work, I will have gone home. 我一完成此工作,就回家。
(從句中的謂語動詞用現在完成時have finished,表示將來完成時,絕不可用will have finished)
If he comes back, please let me know.如果他回來了,請通知我。
(從句中的謂語動詞用comes back,表示一般將來時,絕不可用will come back)
