你好。答案是C
The last decade== PEOPLE - - - FROM 2000 TO 2010 / BETWEEN 2000 AND 2010. 所以用
一般过去时,不用
现在完成时。记住,the last decade在这里是做主语,不是时间状语。 in the last decade需要句子的谓语是has witnessed。 又如:
The 1990s witnessed / saw a rapid development of the local economy in Shanghai.
==People saw / witnessed a rapid development of the local economy in Shanghai in the 1990s.. .记住,主语与时间状语不是同一个概念。
