Question

【题目】The price of houses in that city has reached an unbelievable level, but six years ago no one could have expected that they ______ so sharply,

A. rose

B. had risen

C. were rising

D. were to rise

Answer 1

【答案】D

【解析】本题考查时态。句意为“那座城市的房价已经上升到了难以置信的水平，但六年前，没有人会预料到房价上升会如此剧烈”。理解句意，显然rise动作发生在could have expected之后发生，所以应该用过去将来时，“be动词+不定式”可以表示将来，故答案为D项。答案C的过去进行时不能表示将要发生的动作。
