以往完成进行时是相对以往的某个时刻而言已对现在也有直接关系而且还在所进行的动作。在英语时态中，“时“指动作所发生的时长，”态“指动作的模样和状态。 放到间接引语或虚拟语气里时它语态不能往前推，往后推是现在完成进时。
它基本结构 had been 形容词-ing

英文以往完成进行时是什么意思？
以往完成进行时构造 sb(别人）. had been doing sth（某件事）. 以往完成进行时与过去完成时的用法很相仿，它一般表明某一以往正在进行中的动作或情况，持续到以往某一时刻，还没完成，一直持续到以后的现阶段才结束。 如今完成进行时：sb(别人）.have been doing sth（某件事）. 表达的意思主要有两种：
1.表明从过去某时逐渐一直持续到现在的动作，而且也将持续下去。
2.表明在说话时刻以前到现在正在进行中的动作。 针对此题而言：用现在完成时的主要原因是：表明从过去某时逐渐一直持续到现在的动作，而且也将持续下去。从过去开始就逐渐盼望得第一名，患上第一以后，还将继续盼望下来，由于谁不想多得好多个第一啊，因此从过去某时逐渐一直持续到现在的动作，而且也将持续下去，用现在完成时。
