This course aims to enable students to compare and contrast the differences between Chinese and English with respect to phonology, morphology and syntax. Chinese is evidently different from English, but their differences are not totally arbitrary, but fall under some limited bounds. . This course shows how their grammatical properties can be accounted for in a principled way by general linguistic theory. After attending course lectures, the students will not only have an adequate understanding of the grammars of Chinese and English but can also see the limit to variations.
