II. 例题
例1 Do you know any other foreign language____ English?
A except B but C beside D besides
解析：A、B两项except等于but，意为"除了…"，C-beside意为"在…旁边"，不符合题意。而D-besides, 意为"除了…之外，还有"。所以该题正确答案为D。该题意为：除了英语外，你还知道别的语言吗？
例2 He suddenly returned ____ a rainy night.
A on B at C in D during
解析：我们均知道，at night这一短语，但如果night前有修饰词，表具体的夜晚，则要用介词on来修饰，故该题正确答案为A。
例3 I'm looking forward ____your letter.
A to B in C at D on
解析：该题正确答案为A。look forward to 为固定搭配，意为"期望、盼望"。
