题型：不详难度：来源：

She is too slow. She ________ pass the test, but she __________ too little.

A．would; knew

B．will; knows

C．would; knows

D．will; knew

答案

C

解析

shouldn’t have come意为“本不应该来” ，暗含 “她来过了” 的意思，与题意不符；needn’t have to come中need为情态动词，倾向于主观上的“必要”，与题中给出条件“We had changed our plan”不符；didn’t need to come中的need to do表示“(有责任、有义务)做某事”，符合题意。
