9、B,剖析：这是2012年安徽省中考题，看四个选项，就知道考查时态，根据句子里的标志usually, 我们就确定选一般现在时：用动词第三人称单数，所以答案是A。,18,现在我们利用情景来理解现在进行时：,19,现在我们找出每个句子的标志，谁能找出来吗？,20,现在我们在句子里找出现在进行时！,21,现在我们正在上课，而昨天的这个时候Jerry在做什么？Look at a picture.,Jerry was swimming this time yesterday.,过去进行时,22,昨天这个时候，也就是下午2:30那些人在滇池里做什么？,The people were cleaning Dia
