She doesn’t ______ a new dictionary because she bought _____ a week ago.
A.need to buy, one
B.need buy ,one
C.need to buy ,it
D.need buy ,it
答案
答案:A
A 考查情态动词和代词。“她不必买一本新字典,因为她一周前买了一本了。”“不必”don’t need to do sth. = needn’t do sth. = don’t have to do sth.one指代可数名词,且泛指同类中的一个,it特指前文提到的那个,that指代不可数名词。这里是泛指一本字典,故用one。
