The document discusses the register of research writing. It defines register as the language variety used in a particular situation based on field, mode, and tenor. The field of research is the area of knowledge and researcher's claim/position. The mode is that a thesis follows conventions of a genre. The tenor depends on the relationship between the researcher and intended audience/addressee, which should be other scholars in the field. The document emphasizes that acquiring English for research means internalizing Western ways of thinking while maintaining an awareness of one's own cultural identity and location.
