It’s a modern city.” A. have gone B. have been C. had gone 【答案】B 考查动词时态及动词的用法。问句用的是现 在完成时，答句也应该用现在完成时，前后 时态一致。have gone意为“去过，但还没回 来”；have been意为“去了，回来了”。根 据句意：你去过东京吗？我去过两次，它是 一个现代城市。故选B. 【2012黔西南】He _________his hometown for twenty years. He really misses it! A. has been away from B. left C. has left D. is away from 【解析】A 考查动词的时态。从“for+一段时间”时 间状语可知用现在完成时，因此，只能选 择A或C选项；而leave是瞬间性动词，不能 持续一段时间，所以要将leave变成be away from，故选A答案。
