What the article actually reported was that the two had hidden in a trailer which was driven out of prison, allowing them to escape.
I grew up speaking and reading English (the American version, that is).
For example, do you really think it is necessary to define systolic blood pressure if your readership consists of physicians or cardiovascular physiologists?
Technical writing differs from the writing of fiction, opinion pieces, scholarly English papers, etc. One way is in the use of superlatives and subjective statements in order to emphasize a point. For example, in your discussion you might write, "We felt that the fixative was bad, because we had difficulty finding flagella on our Chlamydomonas." Another researcher is unlikely to risk time and resources on the basis of your "feeling." On the other hand, you might write, "The percentage of cells with flagella was inversely proportional to the time they spent in fixative, suggesting that the fixative was causing cells to shed flagella." This is information that another scientist can use.
As a rule, use past tense to describe events that have happened.
Such events include procedures that you have conducted and results that you observed. With every new lab protocol, you folks come up with the darnedest ways of messing up a perfectly good paper.However, if you heed the comments here your reports stand a much better chance of being mistaken for professionally written research papers.Use of the wrong verb tense, at best, is irritating to read and reflects poorly on the student's writing skills.At worst, the reader can be confused as to what facts are already known and what was newly discovered in the actual study that is the subject of the paper.In some cases omission of anecdotal information is unfortunate.Papers in the older literature tend to be a lot more exciting and often more informative for those not 'in the know,' because the researcher could report how a conclusion was reached, including the reasoning and various sidetracks that led him/her to conclusions.Your readers can figure out to what field(s) your work applies.You need not define terms that are well known to the intended readership.Imagine the difficulty faced by a non-native speaker who learns proper English and then reads the local rag or tries to make sense out of reports by "talking heads" on new shows.Incomplete sentences, redundant phrases, obvious misspellings, and other symptoms of a hurriedly-written paper can cost you.
