Tense and Context
The third problem you may be having with verbs is choosing the correct tense for the
context. As you have seen from Table 1, The English tense system, which gives you
information about time, is complicated. It requires that in your writing you are able to
shift your perspective from whether things are happening now (present), to whether
they have already happened (past), to whether they will happen in the future.
Fortunately in academic written English, the range of tenses commonly used is much
narrower than in spoken English. Mostly we find either simple forms e.g. simple present,
simple past or forms with one secondary tense e.g. present perfect and past perfect.
The following two texts should illustrate this. One is an essay from the social sciences;
the other is a research paper from the physical sciences.
Each finite verbal group in the main clauses of the texts have been highlighted and then
the verbal group has been placed in a column which indicates whether it is past time,
present time or future time. Please note that not all of the essay (Text 1) or the research
paper (Text 2) has been reproduced.
