38、 than)”；“一到(=as soon as)”；“当某时候到了=when (the time in dicated ) comes”；“到时为止”等。时间上有过去、现在和将来之别。动词本身有动作与状态之分，其时态可为一般式、完成式、进行式或完成进行式。现分述如下：1、“by时间”与动作性强的动词连用时，主句多用于完成式。by后的时间可指现在、过去或将来时间点。如：By the time he was fourteen year sold，he （learn） maths all by himself.到14岁的时候，他就已经自学了数学。I (finish) it by the time y

40、 ought to be here by this time /by now.他此刻（现在）应该已经来到这里了。如强调某状态在某时间前已经完成，也常用完成式。如：By next Sunday you will have stayed with us for three months.至下星期日为止，你将与我们相聚三个月了。3、“by时间”与祈使句连用，用于一般式。如：Please finish the task by the end of the month.请在月底前完成这项任务。Be here by this time tomorrow.明天这个时候要到这儿。4、如强调某状态或动作在某时间为止还要继续下去，还可用完成进行式。如：By the time you graduate,I shall have been working here for five years. 到了你毕业时，我就在此地一直工作了五年之久。
