Hi teachers.<br/><br/>What kind of structure do these sentences have?<br/><br/>I'm going to get very wet if that bus doesn't come soon.<br/>I'm going to be late if the train doesn't arrive on time.<br/><br/>It is future the first part, but then the second one has an if clause. <br/>Is there a grammatical name for these kinds of structures?<br/><br/>Thanks in advance
