What are endocentric construction and exocentric construction? （武汉大学，2004）
答案是: An endocentric construction is one whose distribution is functionally equivalent, or approaching equivalence, to one of its constituents, which serves as the center, or head, of the whole. A typical example is the three small children with children as its head. The exocentric construction, opposite to the first type, is defined negatively as a construction whose distribution is not functionally equivalent to any of its constituents. Prepositional phrasal like on the shelf are typical examples of this type.
