解析

【分析】本题为英语词汇词形转换题,需掌握不同词性的构词规则:普通可数名词复数一般直接加s;反义词常通过添加前缀(如im-、un-)构成;副词多由形容词加后缀-ly转换;部分动词可通过现在分词转化为介词;动词变名词需掌握对应后缀(如-tion、-er等);动词变形容词可通过添加后缀(如-ive、-able等)实现。解题时需根据每个单词的要求,结合常见构词法规则完成转换。
【解析】1. stamp是普通可数名词,复数形式直接加s,故为stamps;2. possible(可能的)的反义词添加前缀im-,构成impossible(不可能的);3. real(真实的)变副词添加后缀-ly,构成really(真正地);4. include(包含)的介词形式为including,用于引出举例内容;5. explain(解释)的名词形式为explanation(解释,名词);6. own(拥有)的名词形式为owner(所有者,名词);7. collect(收集)的名词形式有collector(指收藏家,表人)和collection(指收藏品,表物);8. lock(锁;锁住)的反义词添加前缀un-,构成unlock(解锁);9. attract(吸引)的形容词形式添加后缀-ive,构成attractive(有吸引力的);10. value(价值)的形容词形式添加后缀-able,构成valuable(有价值的)。
【答案】1. stamps 2. impossible 3. really 4. including 5. explanation 6. owner 7. collector / collection 8. unlock 9. attractive 10. valuable

本题为词汇适当形式填空题,需先分析每个句子的语法结构,判断空格处所需的词性,再结合括号内的提示词进行词形转换,同时注意固定搭配的运用。具体思路为:1. 观察空格前后的搭配(如be动词后接形容词);2. 分析空格在句中所作成分(如修饰动词用副词,作主语/宾语用名词);3. 结合提示词的词性变化规则(如动词变名词、形容词变副词等)得出答案。
