Adverbial clauses, different types.


  • ADVERBIAL CLAUSESETSI de TelecomunicacionesEnglish

  • ADVERBIAL CLAUSESINTRODUCTIONDefinitionThey modify a verb (either finite or non-finite), an adjective, an adverb or another clause.e.g.:Dont start before the machine is ready for operationFunctioning until the transmission was completed, the link provided an optimum performanceThe portable was simpler than it was expectedThe programmer worked harder than he ever did beforeAs it turned out, the satellite did not fulfil safety requirements

  • ADVERBIAL CLAUSESINTRODUCTION (2)PositionMost commonly, at the beginning or the end of the main clause. In some cases, medial position.e.g. : If possible, use a different method The scene must be illuminated until a distinctive image appearsI was told that, if I applied early, I would be given an immediate answer


    Classification of adverbial clausesThe exact number of adverbial clauses is open to doubt, since meanings sometimes overlap and the same clause may express different semantic values. The meaning intended by the clause can be deduced either from the introducing conjunction or from the sentence as a whole.Here, we shall consider the most common types, and more precisely, those that appear more often in technical texts.

  • ADVERBIAL CLAUSESCLAUSES OF TIMEThey answer the question When? and are common in the initial or end position.Main conjunctions: WHEN, WHENEVER, BEFORE, AFTER, UNTIL, SINCE, ONCE, AS, NOW THAT, AS SOON AS, AS LONG AS, THE MOMENT, DIRECTLY, WHILE.Some of these conjunctions may introduce verbless or abbreviated time clauses.

  • ADVERBIAL CLAUSESe.g.:When the line is engaged, the hold-on mode is automatically assignedSignals were modified as they entered the first multiplexorDirectly the data arrived at its destination, the user interface transformed the flow into intelligible informationNow that the research connected with the telecommunications field is advancing so fast, work prospects are also increasingWhen in doubt, ask for information (verbless)Once finished, disconnect the equipment (abbreviated)

  • ADVERBIAL CLAUSESCLAUSES OF PLACEThey answer the question Where?.Conjunctions (also for verbless and abbreviated clauses): WHERE, WHEREVER e.g.:Answer yes or no where appropriateWherever possible, all parts should be tested

  • ADVERBIAL CLAUSESCLAUSES OF CONDITIONThese clauses give the circumstances under which the statement of the main clause will take place or be true, i.e., they state the dependence of one circumstance or set of circumstances on another.Main conjunctions: IF (positive cond.), UNLESS (negative cond.), PROVIDED THAT, PROVIDING, SUPPOSED, SUPPOSING (mostly connected with questions), SO LONG AS, AS LONG AS, SO THAT, ON CONDITION THAT.


    If the international line is engaged, you must replace the handset and try againUnless it works properly, results will be unreliable (If it doesnt work properly, results...)Supposing the teacher saw you cheating, what would you do?You will be given the prize provided (that) your project is a noveltyThe director will phone you on condition that you make an appointment previously(Notice that the comma is compulsory whenever the subordinate comes first)

  • ADVERBIAL CLAUSESReal and unreal conditionsReal: We are not sure whether the condition has been (will be) fulfilled or not.Unreal: It is clear the condition has not been fulfilled (though it could be)e.g.:If it works, it will be a success (Real)If it worked, I didnt realise (Real. Simple past in both clauses. Clearly factual)If it worked, it would be a success (Unreal. Conditional in the main clause. Hypothetical.)If it had worked, I would have realised (Unreal. Impossible)

  • ADVERBIAL CLAUSESClauses beginning with If are similar to questions which imply uncertainty. Thus, they tend to contain non-assertive forms such as Ever and Any.Clauses beginning with Unless stress the excluded positive option and, so, they normally contain assertive forms like Some. For the same reason, these clauses are not usually unreal conditions.

  • ADVERBIAL CLAUSESe.g.:If you ever hear any news from the company, let me knowDont call me unless youve got something new to tell meIf we hadnt upgraded the system, we would have had a lot of problems (unreal condition). *Unless we had upgraded ...Both If and Unless can introduce abbreviated and verbless clauses.e.g.:If ready, lets beginThe lab is closed on Saturday unless otherwise stated


    Special types of conditional clauses1. Present subjunctive used in legal English: If he be found guilty, he will be punished2. WAS TO or WERE TO followed by the infinitive: If it was/were to work, that would be a success3. SHOULD followed by the infinitive: If a crisis should arise, the company would have to close for good4. The conjunction is omitted and the auxiliaries SHOULD, WERE or HAD introduce the subordinate: Should you finish on time, let me know. Were he to call, tell him Im out. Had the project been finished on time, the network would have been operative without undesirable delays5. An infinitive clause can also be used conditionally: To do a thing like that, you must be stupid


    Indirect conditionsThey behave as STYLE DISJUNCTS (Quite useful for oral presentations)a. Conventional expressions of politeness. Speakers utterance seemingly dependent on the permission of the hearer:If you dont mind my saying so, youve made a mistakeIf I may be quite frank with you, youve made a mistakeOther expressions: If I may say so, If I may be personal, If we can be practical for a moment, If I may put the matter as simple as possible, If I may interrupt, If I may change the subject.

  • ADVERBIAL CLAUSESb. Calls for the hearers agreement, suggesting that the wording is not quite precise or that he should not be misunderstood:The Big Bang theory of the origin of the Universe bears a startling resemblance to the description of creation in Genesis, if one may put it so.Other expressions: If that is the correct term, If that is the word for it, If you see what I mean, If you like.

  • ADVERBIAL CLAUSESc. To express either speakers or hearers uncertainty:Chomskys views cannot be reconciled with Piagets if I understand both correctlyOther expressions: If Im correct, In case you dont remember (Ironical: Einsteins theory of gravitation is based on a mathematical concept, in case you dont remember/in case you have already forgotten), If you know what Im referring to.


    Closely associated to conditionals, except that they imply a contrast between two circumstances.Principal conjunctions: (AL)THOUGH, EVEN THOUGH, EVEN IF, WHILE, WHEREAS.Although as a subordinator is approximately the equivalent of but as a co-ordinator. The conjunction EVEN IF implies an overlap between conditional and concessive clauses. WHILE and WHEREAS often point to a contrast between comparable things.

  • ADVERBIAL CLAUSESe.g.:We will do our best, although we are not keen.You will enjoy this program, even if you dislike computers.Whereas services havent been paid their due attention, the impact of technology is constantly in the news.PCs are used everywhere, while Macs are mainly restricted to the office environment.

  • ADVERBIAL CLAUSESThough generally the conjunction IF is conditional, it can be used concessively: If cable TV is gaining adepts, it doesnt seem to.Very often, the conjunction follows the complement: Successful, though it was, the connection only lasted a few seconds.Abbreviated clauses of concession are common with verbless or participle constructions: Though a bit obsolete, we are still working with a Pentium II processor. Though infected, the program didnt cause any damage.

  • ADVERBIAL CLAUSESConditional-concessive clauses1. Alternative conditional-concessive: They give a choice between two possible conditions.. Introduced by the correlative conjunction WHETHER......OR.2. Universal conditional-concessive: Generally introduced by some WH- word or expression (whatever, whoever, no matter wh-...). They can also begin with certain fixed expressions:Come what may (whatever may happen)Do what you will (whatever you do)Be that as it may (however that may be)

  • ADVERBIAL CLAUSESe.g.:The satellite will keep its position, whatever the weather conditions are.Whether the weather improves or not, the satellite transmission wont be subject to undesirable delays.However / No matter how fast the information is input, the system always takes its time to process that.Please, do contact us if you need further information. Be that as it may, thank you very much in advance.


    They give the reason for the activity expressed in the main clause.Main conjunctions: BECAUSE, SINCE, AS...Whereas is sometimes used to introduce a clause of reason in legal English.Conjunctions typically associated with time can also introduce these clauses.In many cases, the conjunction is omitted.

  • ADVERBIAL CLAUSESe.g.:It is true because I say it is.Whereas the defendant has pleaded guilty, the Court will be lenient with him.Well have to rearrange the configuration after we said we would.Being a man of ingenuity, he repaired the machine.We are happy you can manage.



    They state the finality of the action expressed by the main verb. Mainly introduced by: IN ORDER THAT/TO, IN ORDER FOR (+ noun), SO (THAT), SO AS TO... Very often they occur in the form of a full infinitive (as it happened with conditionals).

    e.g.:The program was scanned so that unknown viruses could be found.We left the device connected in order for the staff to access relevant information whenever required.He destroyed the papers so that no one might see them.To open the carcass, you have to press down the button.


    They state what has happened (or may happen) as the result of the action or state expressed by the main clause.Principal conjunctions: SO.....THAT, SO (THAT), SUCH.....THAT, SUCH (THAT).e.g.:We introduced the necessary changes so that the operations gave the expected result.Our finances are such that we cannot afford another increase in the production expenses. Sometimes, clauses of result are similar to clauses of purpose. Compare: We rearranged the configuration so that it could work properly with . . . so that it worked properly.



    They answer the questions HOW MUCH?, HOW LITTLE?. The principal conjunctions are AS, AS THOUGH/IF, AS.....AS, SO.....AS and structures of comparison. If there is doubt or unreality, the past tense is used. Sometimes, an inversion subject/verb is produced.

    e.g.:Mathematicians often behave as though they knew all the answers.This is not a bad result as prices go.The composite is as dry as its going to get.Our company created new branches abroad, as did our competitors.


    CLAUSES OF PROPORTION AND PREFERENCEClauses of proportion express a proportionality or equivalence of tendency or degree between situations. They are introduced by AS or the correlatives THE.....THE (with a fake comparative structure).Clauses of preference are introduced by RATHER THAN or SOONER THAN followed by a bare infinitive. RATHER THAN can also precede a gerund or a noun.

  • ADVERBIAL CLAUSESe.g.:As speed increased, more losses were produced.The more we thought about the matter, the less we understood it.Rather/Sooner than reducing the capacity, Id replace several components.Rather than bulky deflecting coils, well employ an electrostatic focus.



    The usual order Subject + Verb is reversed after the following adverbial elements:1. Adverbial elements of negation: NO, NOT, NEVER, NEITHER.e.g.: In no case can an exception be madeNever had I seen such an outstanding performance2. Negative conjunctions: NOT ONLY.....BUT, NO SOONER.....THAN.e.g.: Not only is it very efficient but its quite inexpensive tooNo sooner had we begun our presentation than the light went off3. Adverbial elements of near (quasi) negation: SCARCELY, SELDOM, RARELY, BARELY, HARDLY.e.g.: Seldom has anyone succeeded in this business


    REVERSAL OF WORD ORDER AFTER ADVERBIAL ELEMENTS(2)4. Adverbial elements including only: Only after the 1992 agreement on borderless trade, is the haze beginning to clear around the concept of the Common Market of Communications 5. Adverbial elements including so, and also after so as a conjunction: So critical did detecting the first failure become that designers decided to choose a redundant configurationThe constant rise in productivity is hardly attributable to human effort only, and so is the globalisation of the market

    6. Adverbial elements of place: Inside the room lay scattered the basic elements employed for propulsion, sensing and control. Among them was the latest microprocessor
