describing the research activity	simple past tense, present perfect tense	The study focused on 2 main areas The framework for life cycle analysis has been developed
describing the methods	simple past tense (active or passive)	We carried out a series of field tests A large number of samples were tested for fracturing
reporting results	simple past tense	Results indicated that the problem is even more serious than previously predicted The third model proved to be more durable than the other four
stating conclusions	present tense verbs indicating tentativeness : is possible is likely appears seems might modal auxiliary verbs can may could might	This indicates that there are, in fact, several factors contributing to the decrease It appears that the incidence of human error cannot be eliminated at any stage   There might be a need for revising the list of criteria within the next 5-10 years
