A situation that is durative and bounded is an Accomplishment. A bounded situation has a necessary endpoint or goal, and the goal is an inherent part of the situation. The process involved is heterogeneous with successive stages advancing toward the final end. To illustrate the definition, compare ‘kàn shū’ (read) with ‘kàn yī běn shū’ (read a book). The former is an activity, for the action of reading can go on for hours, it has no inherent endpoint, though it can stop at any time, then it will have an arbitrary endpoint. In contrast, ‘kàn yī běn shū’ (read a book) is an Accomplishment. The inherent endpoint of the action is the end of the book. As the action of reading proceeds to the end of the book, the reading reaches its goal. The process involved is heterogeneous, for the nearer it approaches the end, the more changes the action has caused (in the subject referent), until the reading is finished, then a result is achieved.
