他总结了三种正确的，争议主要出在第三种
1、n.+be动词+being+done 我们都知道being最典型的错误之一就是n.+being done，只要多加了一个be动词，这就成了合理的被动语态+进行时态，因此正确；
2、prep./固定接动名词的短语或动词+being，因为这是固定搭配，这里边就拿being当be动词的ing形式，自然很好理解；
3、n.+being done，实际上being done是being引导的短语作n.的后置定语。
我们知道，分词短语可以作后置定语，那么为什么不直接用doing做后置定语，而用being done呢？就是有的时候这个doing的动作和被修饰的n.之间是被动关系，所以用being done来表示被动。
第9题即是如此： The computer software being designed for a project studying Native American access to higher education will not only meet the needs of that study, but also have the versatility and power to facilitate similar research endeavors. (D-P10-15)
这里的being done相当于是software的后置定语，但是design和software之间又不是主谓关系，而是动宾关系，需要用被动，所以就多加了一个being，将doing的后置定语改成了being done的形式
因此n+being+done有对有错，对的时候如下，错的时候较多
例如12. During the recession of 1973, home mortgage foreclosures resulted in tens of thousands of Americans being evicted from homes for which they could no longer afford monthly payments. (A-P1-204)
9. The computer software being designed for a project studying Native American access to higher education will not only meet the needs of that study, but also have the versatility and power to facilitate similar research endeavors. (D-P10-15)
