If -clauses

Study these uses of if -sentences.   Action and effect We can use an if -sentence to link an action and its effect. For example: 1. If you click on that [action], that'll just compact your C drive [effect]. 2. If you click on that [action], that opens it up and shows you all your folders [effect].   The action is in the Present simple and the effect is in the Present simple or described using will, can, or may depending how certain it is to follow. Polite instructions   We use the action part of if -sentences, especially in spoken English, to give instructions in a polite way. The effect part is assumed.   3. If you bring your cursor down to the very bottom [ you’l find the Start button ].

4. If you just hit Enter [ that will activate the program ]. Imagined action and effect   We can use an if -sentence to describe the possible effect of an imagined action. For example:   5. If you spilled coffee on your keyboard [imagined action], you could damage it [possible effect].   6. If there were no other folders there [imagined action], you wouldn't have a little box in there [possible effect].   To show this describes imagined, not real, events, the action is in the Past simple and the effect is described using would, could, and might depending how certain it is to follow.
