- 试题详情及答案解析
- Beijing a lot in the past ten years. Now it has become one of the biggest modern in the world.
| A．changes; cities | B．changed; city |
| C．has changed; cities | D．changed; cities |
- 答案：C
- 试题分析：句意：北京在过去十年发生了很大变化。现在它成为世界上最大的现代化城市之一。与时间状语in the past ten years连用，用现在完成时，故第一空为has changed。one of the+复数名词，故第二空为cities。故选C。
考点：考查时态和名词的用法。
