新PREP 201, 即GWD30-Q4

超超琪琪格

从朗文里查到的unqualified的用法，但是没有查到unqualifying的用法，可能前者成为一个固定的形容词了吧，而后者加了ing只是成为一个ing分词，所以那个人才会说：“The -ing form doesn't make sense in this instance because the subject of the qualifying is "labor" (means workers' unions, etc.), not "support". ”不知道这样想对不对？
unqualified  
un·qual·i·fied /?n?kw?l?fa?d US -?kwɑ?-/ adj
not having the right knowledge, experience, or education to do something
　unqualified staff
unqualified for
　He was unqualified for the job.

　I feel unqualified to advise you.
[usually before noun]
used for emphasizing that a quality is complete and total
　The experiment had not been an unqualified success.
　He gave her his unqualified support .

HINT
Do not confuse with disqualified , which means 'officially not allowed to do something': She was disqualified from driving.

考点在unqualified。但觉得如果并非是这个考点，一般现在时的ARE RECEIVING比HAVE RECEIVED要好些。
