Taking in to the consideration the very popular and famous quote “Give a person a fish and you feed him for a day. Teach a person to fish and you feed him for a life time”. This simple but profound saying is attributed to the wisdom of Confucius who lived in the 5th century BC.

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.
For example, you may want to translate a well-established measurement procedure, which is construct valid , from one language (., English) into another (., Chinese or French). Since the English and French languages have some base commonalities, the content of the measurement procedure (., the measures within the measurement procedure) may only have to be modified. However, such content may have to be completely altered when a translation into Chinese is made because of the fundamental differences in the two languages (., Chinese and English). Nonetheless, the new measurement procedure (., the translated measurement procedure) should have criterion validity that is, it must reflect the well-established measurement procedure upon which is was based.
