1.D 现在完成进行时和时间段for hours搭配；for a long time很长时间,不如前者的for hours准确；already已经,不能和现在完成进行时连用；yesterday是一般过去时的时间状语
2.C had been watching是过去完成进行时,和句尾的时间状语相呼应.has been doing是现在完成进行时,大7天假日已经过去,故时态错误；was doing是过去进行时,表明在过去是一段时间里一直进行的动作,但他不可能在7天除此什么都不做了,另外和for hours也不匹配；was being doing,没有这种时态.
have been doing和have done的区别：前者强调进行性.两者经常可以换用.

We have been talking about this topic _ for a long time____ .
选 A 吧。
我们已经讨论这个话题很久了。.
好像记得说 have been doing 是过去在做，一直延续到现在，未来可能要继续做下去。
所以不是已经完成 B. already
这是一个现在的时态，所以不是 C. yesterday （过去）D:for hours （一般现在/过去）
※网上有人说 a long time 没有 for hours 具体，我还是想选 a long time。哎！我就是觉得 for hours 有一般现在时的感觉，见例句如下：
Sitting for hours can shave years off life. 久坐减寿。
Tom ____ watching China Open for hours during the seven-day vacation.
A has been B was C had been D was being
选 C 吧，during the seven-day vacation 在七天假日里，是过去时态，排除 A。
根据 for hours 选择完成时态 C。
哈哈~~

1.have been doing 代表有限一段时间内一直在完成的动作，have done 仅仅代表已经完成的那个瞬间，所以
我觉得应该选A吧。
2.同样的理由， 因为是for hours，一段时间内完成的动作，应该是have been，during the seven-day vacation.告诉我们是在七天的假期内做的，也就是说是过去发生的事，所以应该用had been
