为什么是increasing?to increase可不可以?increased可不可以? Whether increasing teacher's salary is the best way to improve the quality of education has been discussed.
就是说主语只能是动名词,不能使to do 或者动词的ed形式,对吗,就是不明白Whether to increase teacher's salary is the best way to improve the quality of education has been discussed这样行不行,就是把increasing换成to increase。
如果是上文这样的话,whether to increase teacher's salary是主语,后面出现了两个谓语(is和has)。那么为什么increasing是对的呢,那是因为whether后面接了一个句子作为了主语,那么is就作为了whether所引导的主语从句中的动词,has才是整个句子的谓语。
