14.This morning the Greenswere cleaning (clean) the house,but I am not sure if they have completed it.分析 今天早晨,格林一家在打扫房子,但是我不确定他们是否已经完成了.
解答 答案:were cleaning 提示词clean,动词,打扫,清洁.根据but I am not sure if they have completed it.但是我不确定他们是否已经完成了.可知过去动作一直持续进行.再根据时间状语This morning,可知应该用过去进行时态.过去进行时态构成:was/were+doing,主语是the Greens,格林一家,是复数,故填:were cleaning.
