助动词“可以”在现代汉语中有时用于表示客观能力。通过对不同时期语料的统计和建模,能够证明:这种看似非典型的用法并不是新兴的,而是古代汉语中旧有用法的保留,是“可以”词汇化过程留下的痕迹。因此,不能简单地因其形态类似而将其归入受工具主语支配的类型之中。 Auxiliary verb “can ” is sometimes used to express objective ability in modern Chinese. Through the statistics and modeling of the corpus in different periods, we can prove that this seemingly atypical usage is not new, but the retention of the old usefulness in ancient Chinese is the trace left by the lexicalization of “can” . Therefore, it can not be simply categorized into the types subject to the subject of the tool simply because of its morphological similarity.
