问题描述：
Not only__the computer he___been sold by his son for gambling debts
Not only __ the computer he ___ been sold by his son for gambling debts but also his new car.(答案是has:had)为什么不填/：has?
为什么是has the computer?
答
computer的后面接的是一定语从句,发生在过去,所以是sold.且是被动句.
第一个空应填has,因为这是一般现在时用法.
答
1^电脑已经被卖掉，用has是现在完成时，强调对现在的影响故用has 。NOT ONLY置于句首后面要主谓倒装，故有has the computer
2^电脑已经被他儿子卖掉了，他现在已不复拥有了，只是过去拥有，故用had
答
the computer he has had been sold by his son
the computer had been sold
他所拥有的那台电脑被他儿子卖了.
因为not only放在句首,所以句子用的是倒装.
答
句子需要隔开
Not only has /the computer he had/ been sold by his son for...
the computer he had 省略that, 其实是定语从句. 这部分如果用A 代替的话为:
Not only has A been sold by his son for.. 这样就通了.
