1.3. Morphological peculiarities of a scientific text. First impressions of the language of science are that its distinctiveness lies in its vocabulary. But this should not lead us to disregard certain typical grammatical features of scientific English which similarly to lexical ones result from general impersonality and stereotypeness of expression in a ST.

· One of widely-quoted stereotypes of scientific English grammar is an extensive use of Passive Voice constructions which can be regarded as a helpful way of ensuring objectivity and generalization in presenting scientific facts and ideas.

It should be noted that impersonal Passive Voice constructions with the verbs ‘suppose’, ‘assume’, ‘infer’, ‘point out’, etc., as in ‘ It can be inferred ’, ‘ It must be emphasized ’ are also frequently used.

· A concern for objectivity and generalization also results in a wide use of impersonal constructions with the pronoun ‘one’, as in ‘ one may assume ’, ‘ one can really see ’, ‘ one cannot help noticing ’, etc.

· The use of the personal pronoun of the 1st person plural ‘we’ can also be selected as an example of a generalized form of expression in scientific writings. It serves to reflect a joint, collective nature of scientific research, on the one hand, but it can also aim at involving the specialist reader into the process of scientific reasoning and demonstration, on the other. It is sometimes regarded as a means of ‘the author’s modesty’.

Some other features typical of the grammar of academic and scientific writing:

· the prevalence of present tense-forms of the verb in scientific reasoning, mostly the Present Indefinite or the Present Perfect, e.g. ‘ Here we consider the case of exact resonance ’, ‘ Organic geochemical procedures and contamination controls have been developed to be applied to the samples containing minute amounts of organic compounds ’.

· rather an extensive use of various Subjunctive Mood forms as means of making scientific statements, assumptions, inferences sound less straightforward, e.g. ‘ If this were done for each parameter, the resulting normal equations would be nearly diagonal … and the convergence of the least-squares process would be accelerated ’, ‘ It would be more accurate to say that diffraction is not the only influence which limits the performance of a spectrometer ’.

· Another fairly typical feature of scientific English is a frequent use of non-finite forms (Infinitive, Participle, Gerund) in different syntactic functions within a sentence and within certain predicative complexes, especially, Subjective-with-the-Infinitive, Objective-with-the-Infinitive, Absolute Participial Construction, e.g. ‘ The electrization of bodies is expected to be given account of in terms of atomic structure ’. ‘ The equation seems to hold only for symmetrical molecules ’. ‘ The existing data being limited, no definite conclusions could be made ’.

1.4. Syntactic peculiarities of a scientific text. The language of science has developed a complex, extended syntactic structure, as it tends to integrate several relevant issues into a single statement.

· The overwhelming majority of sentences in a ST are complex ones, often comprising a number of different subordinate clauses, because logical unfolding of scientific reasoning in a ST simply requires the use of ‘that’, ‘because’, ‘as’, ‘if’, ‘but’, ‘although’, etc. clauses.

· The relations between words within a sentence and between clauses and sentences are often made explicit through the abundant use of various conjunctions, conjunctive words and parentheses. Double correlative conjunctions are also fairly typical of scientific writing, e.g. not merely… but also, whether … or, both … and, as … as, etc. It will not be an exaggeration to say that in no other functional style do we find such a developed and varied system of connectives as in scientific prose.

· Simple sentences, both unextended and extended ones, are not numerous, but the very compactness of their structure brings out their informative significance against the background of the structural complexity of the rest of the sentences.

· The necessity to present scientific information in an as complete and detailed way as possible gives rise to a wide use of different types of attributes, both prepositive and postpositive ones, among them prepositive attributive groups comprising strings of nouns of the type N+N+…+N, e.g. world-population-growth rate, shock-wave-velocity measurement, anti-aircraft-fire-control systems.

Many nouns are modified by attributive Participial, Gerundial or Infinitive constructions for the same reason, e.g. ‘ The first effect to consider in solving the problem is the additional heat ’. ‘ The aim of this paper is to find a proper value for the indices involved ’. ‘ The mere fact of there being a written constitution in the USA does not mean by itself the solution of the problem ’.

· The word-order on the sentence level is mostly direct, though there are cases of grammatical inversion which serves as a means of cohesion with the above-said, e.g. ‘ Between the receptor and the connector stands an intermediate set of elements ’.

· The unusual word-order of some adjectives or adverbs is observed in certain syntactic constructions where it is used for emphatic purposes:

- However + Adj / Adv + S + P…, e.g. ‘ However often we may observe pieces of gold to dissolve, we must still allow it to be possible that … ’
