already和yet都可以作为现在完成时的标志词，但它们的用法不同。already一般用于肯定句中。 We have already cleaned up ur classrm. 注意：already用于疑问句中时通常表示惊奇。如： Have yu finished yur hmewrk already? yet一般用于疑问句和否定句中。 Have yu seen her yet? The bus hasn’t cme yet.
现在完成时：表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，不能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。
一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。
