题型说明：Directions: In this section, there are 20 incomplete sentences. You are required to complete each one by deciding on the most appropriate word or words from the 4 choices marked A), B), C) and D). 3. (0.0分) So far, we ___ in this city for five years, and we have seen many changes during these years.A. had livedB. livedC. liveD. have lived

本题考查现在完成时的用法。解题关键在于识别时间状语"so far"和"for five years"的提示作用，以及句子中动作的持续性。现在完成时表示过去发生的动作持续到当前，需使用have/has + 过去分词的结构。

选项分析

A) had lived

• 过去完成时，表示动作在另一个过去动作前完成，与题干中"so far"（强调持续到现在的动作）矛盾，排除。

B) lived

• 一般过去时，表示动作已结束，无法体现"for five years"的持续性，排除。

C) live

• 一般现在时，表示经常性动作，但"for five years"需持续性动词搭配，且无法体现时间的延续性，排除。

D) have lived

• 现在完成时，正确体现动作从过去持续到当前，并与"so far"和"for five years"的时间提示一致。
