　　II. 例題

　　例1 Do you know any other foreign language____ English?

　　A except B but C beside D besides

　　解析：A、B兩項(xiàng)except等于but，意為"除了…"，C-beside意為"在…旁邊"，不符合題意。而D-besides, 　　意為"除了…之外，還有"。所以該題正確答案為D。該題意為：除了英語外，你還知道別的語言嗎?

　　例2 He suddenly returned ____ a rainy night.

　　A on B at C in D during

　　解析：我們均知道，at night這一短語，但如果night前有修飾詞，表具體的夜晚，則要用介詞on來修飾，故該題正確答案為A。

　　例3 I'm looking forward ____your letter.

　　A to B in C at D on

　　解析：該題正確答案為A。look forward to 為固定搭配，意為"期望、盼望"。

　　二. 連詞

　　(2) 從屬連詞用來引導(dǎo)從句，如that, if, whether, when, after, as soon as等。

　　除了從屬連詞(引導(dǎo)狀語從句)外，還有其它可以用來引導(dǎo)從句的詞類。它們是連接代詞和連接副詞(引導(dǎo)名詞性從句)，關(guān)系代詞和關(guān)系副詞(引導(dǎo)定語從句)。
