高中英語狀語從句

1、 狀語從句一狀語從句定義 狀語從句是一個相當于副詞的從句，在句中起副詞的作用，充當狀語。狀語從句主要分為時間，地點，原因，方式，條件，讓步，比較，目的和結(jié)果狀語從句。溫馨提示：一般情況下，狀語從句從句的引導(dǎo)詞在狀語從句中不充當成分，根據(jù)上下文的邏輯關(guān)系來選引導(dǎo)詞，所以要重點掌握狀語從句的引導(dǎo)詞的含義。 二.狀語從句的引導(dǎo)詞 狀語從句中的常用連詞和特殊連詞 從句類型常用連接詞特殊連接詞時間狀語從句when，while，as，before，after，since，till，until，as soon as,by the time一些時間名詞：the moment，the instant，the m

8、ncebeforebeforethatwhen注解答此類題目關(guān)鍵有三點：首先要確定是不是強調(diào)句，當我們把it is/was以及連接詞去掉時，剩余部分若能構(gòu)成一個完整的句子，就是強調(diào)句，這時連詞用that；否則，就要考慮它的句式特點。其次要看是時間段還是時間點。再次是連接詞前后的時態(tài)。當確定為時間段時，連接詞前后時態(tài)不一致，用since；時態(tài)一致，用before；當確定為時間點時，強調(diào)句就用that，否則就用when。 The moment he saw me ,he recognized me. 他一看見我，就認出我了（the moment,the minute, the instant 名詞
