【正确答案】正确答案：Free forms or morphemes are independent units which can stand by themselves and sometimes act as complete utterances. They are opposite to the bound morphemes which have to appear together with other morphemes without any space between them.(5 points)Minimal free form means that a word is the smallest unit that can constitute,by itself,a complete utterance.(3 points)In my opinion,a word can be seen as the minimal free form, and a word itself can constitute a sentence. For example: —Is Jane coming this evening? —Possibly.(3 points) In the exchange above,"Possibly" is both a word and a complete utterance. Other expressions like "Hi" , "Darling" and "Yeah" can function the same way.(3 points) However,there are some traditionally recognized words fail to satisfy Bloomfield"s definition. For example,"a" and "the" cannot stand by themselves in the usual sense and they appear with nouns or adjectives.(4 points) But the advocators cite the following example as an exception: —What is missing in the sentence"Dog is barking" ? —A.(3 points) Therefore,other criterion to define a word should also be considered, such as stability and relative uninterruptibility.(4 points)

【答案解析】解析：本题考查对布龙菲尔德“单词是最小的自由形式”的辩证理解。最小自由形式(语素)：能够自己独立存在的单位，与粘着语素相反；“最小自由形式”：能够独立构成一个完整句的最小单位。有时一个单词也构成了一个完整的句子，例如：“Possibly”，“Hi”。但是有些单词除特殊情况外，不能独立构成句子。例如：“a”和“the”除了个别情况外，并不能独立出现，它们必须和名词或形容词搭配使用。因此，要确定词的定义必须考虑到其他特点：稳定性和相对连续性。
