答案
D
解析

试题分析:句意:--约翰,你看起来这么累?--我一直和吉米在打乒乓球。现在完成时可以表示一个已经完成的动作,对现在造成的影响。现在完成进行时的肯定句:“主语+have(has) been+动词的现在分词+其他.” 现在完成时通常只陈述事实,而现在完成进行时还可表示一种感情色彩。现在完成进行时通常用来谈论较短暂的动作或情况,若要谈论时间延续较长的动作或情况或永久性情况,则通常用现在完成时。这里表示现在完成进行时表示在说话时刻之前刚刚结束的动作。故选D。
点评:本题难度适中。语境中的时态具有灵活多变的特点,因此找出隐含于上下文中的时间信息,正确认定动作行为所发生的时间是解题的关键。
即学即练:Experiments of this kind______in both the U.S. and Europe well before the Second World War.
A. have conducted    B. have been conducted  C. had conducted    D. had been conducted
解析:D。句意:“就在二战爆发前,美国和欧洲都进行过这种实验。”首先考虑语态,主语experiment与conduct构成动宾关系,谓语使用被动形式。题干中出现the second war是过去的时间点,before the second war是过去的过去,因此使用过去完成时。选D。
