VI. 单项选择。
1. C 【解析】句意：在单词“spell”中有一个字母s，在单词“you”中有一个字母u。an用在元音音素前，a用在辅音音素前。s的发音是/es/, u的发音是/ju:/。故选C。
【点睛】冠词的用法：
冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。英语中的冠词有三种，一种是定冠词，另一种是不定冠词。an, a是不定冠词，仅用在单数可数名词前面，表示 “一”的意义，但不强调数目观念。a用在以辅音（指辅音音素）开头的词前，a用在以元音（指元素音素）开头的词前。the是定冠词，修饰特指名词翻译成 “这个”。如果泛指某物,用a,/an,具体指某物的话，用the。
3. D 【解析】句意：这些书是你的，我的书在那边。考查形容词性物主代词和名词性物主代词辨析。物主代词分为两类，形容词性物主代词和名词性物主代词。形容词性物主代词后面需加名词，而名词性物主代词则不加。在前句的空格后没有名词，所以填名词性物主代词。后句空格后有名词books，需加形容词性物主代词。my、your都是形容词性物主代词，mine、yours都是名词性物主代词。根据句意，故选D。

【点睛】can能，会 can’t不能，不可能，通常用于否定句的推测；should应该，shouldn’t不应该；may可以，可能，通常用于肯定句的推测，may not可能不；must必须，一定；mustn’t禁止。情态动词后接动词原形，变疑问句时把情态动词提前，变否定句在情态动词后加not。must引导的一般疑问句，表示必须时，否定回答用needn’t；may引导的一般疑问句，否定回答用can’t
