<P><b>Causative constructions</b></P><P>When one does not carry out an action oneself but rather has the action done by someone else, this is expressed by a <U>causative construction</U>. In English it is the verb "<B>to have</B>" that introduces the causative. The model will generally be: "<B>to have</B>" (conjuguated) <B>+ direct objet </B>(noun or pronoun) <B>+ principal verb</B> (in its past participle form):</P><UL><LI>We'll <U>have a monument erected</U> on this site. <LI>I <U>had my hair cut</U>. </LI></UL><P>When one wishes to designate the agent of the action (the person who has carried out the described action), there are two possibilities:</P><P>1. -- "<B>to have</B>" (conjuguated) <B>+ direct objet </B>(noun or pronoun) <B>+ principal verb</B> (in its past participle form) + "<B>by</B>" + <B>agent </B>(usually not as a pronoun):</P><UL><LI>The professor <U>had the work done by his lab assistants</U>. <LI>I <U>had it done by my employees</U>. </LI></UL><P>2. -- "<B>to have</B>" (conjuguated) <B>+ agent </B>(as a direct object noun or pronoun) <B>+ principal verb</B> (in its infinitive form) + <B>the object </B>(also in the form of a direct object noun or pronoun)</P><UL><LI>The professor <U>had his students write an essay</U>. <LI>I <U>had him do it</U>. </LI></UL><P><B>Note: </B>Especially in spoken English, the verb "<B>to get</B>" often replaces "<B>to have</B>," in which case "<B>to</B>" is added to the infinitive (but not before past participles). This construction also suggests that it may be (or have been) difficult to produce a certain reaction on the part of the agent:</P><UL><LI>We'll <U>get</U> a monument erected on this site. <LI>The professor <U>got</U> his students to write an essay. </LI></UL><P>When one wishes to express a change in temperament or in general conditions, it is the construction "<B>to make + adjectif</B>" which is used:</P><UL><LI>That letter <U>made</U> her <U>sad</U>. <LI>He <U>makes</U> me <U>furious</U>! <LI>That new problem <U>made</U> negotiations really <U>hard</U>! </LI></UL> |
