Many teachers have come to realize that one of the keys ____ their students lose interests in their subjects is to changes ways of teaching.
A.to not letting B.not to let C.not to letting D.to letting not
答
the key to doing sth,and "not" should be put between "to"and "doning".
答
the keys to固定搭配,not letting 在to的后面,这个to是介词,后面的词语表目的,介词后面动词加ing,所以let加了ing
答
the key to ...意思是 ...的钥匙;...的关键.
这里的to是介词,所以要在介词后面进行否定,即 the key to not...
而 let 是实意动词,介词后面需要将其改为动名词,就是 the key to not letting.
选A
