是
with the economic development
這里的
economic （經(jīng)濟(jì)的,經(jīng)濟(jì)上的）
是形容詞,
修飾 development （發(fā)展）
例句：
With the economic development of the region now on a solid footing, the government can turn it's attention to other pressing matters.
因?yàn)檫@個(gè)地區(qū)的經(jīng)濟(jì)發(fā)展現(xiàn)在鞏固了,政府可以把視野轉(zhuǎn)移到其他緊迫的問題.那將 economic改成economy呢？只能是 with the development of economy嗎？如果 economic 改成 economy， 要加冠詞 the ：with the development of the economy
