<u>Situations that are contrary to fact</u>, the mood is the conditional: third type. Example: If she<u> had got up</u> early, she <u>would not have missed </u>the bus. This example illustrates an imaginary situation; it did not happen. What truly happened was that the woman got up late and missed the bus. This was the fact. The structure is : the condition introduced by "if" carries the Past Perfect and the imaginary result carries would + perfect infinitive.
<u>Conditions under which a situation might occur, </u>the mood is the conditional: second type. Example: If she <u>bought</u> an alarm clock, she <u>would get up</u> on time. This statement reflects a possible solution to a problem; it is a speculative solution. She does not have an alarm clock, yet if she <em>bought</em> one . This is the subjunctive mood . What would the result be? She <u>would get up</u> on time. This is the conditional mood , second type.
