【答案与解析】
1. C 考查冠词。表示数量“一”用不定冠词，pair是以辅音开始，所以用a。
2. B 考查名词的数。由five可知，要用复数可数名词，C是不可数名词，D是单数可数名词，A的复数变错了，应为potatoes，因此，只有B正确。
3. B 考查物主代词。由语境可知，该句是说“这不是我的(词典)”，应用物主代词。排除C和D；又因为my只能在名词前作定语，而后格后没有名词，作表语要用名词性物主代词，所以用mine(=my dictionary)。
4. A 考查疑问词。表示“……是什么样子的？”是固定句型：What…look like?
5. A 考查形容词。从died和答语来看，可知John是“悲伤”或“难过的”。
