Example of different forms of eliminate and express. Sentences (1)–(3), three different sentences using predicate eliminate taken from MEDLINE  and EMBO  Journal articles, are given as examples to illustrate the variation of the language usage in biological articles. To convey the information marked as [...A] or [...B] or [...C] can be written in various forms as discussed in the main text. Similarly, the variation of surface linguistic expressions can also be seen from sentences (4)–(6) conveying event express. Sentence (6) is an example to show that the domain knowledge is really necessary for correct understanding.
