Question

A clean environment can help the city bid for the Olympics，which ________ will promote its economic development.

A．in nature	B．in return
C．in turn	D．in fact

Answer 1

C

C　[in turn意为“又反过来”，句意：清洁的环境有利于申办奥运，而申办奥运又可以促进经济的发展。C项符合句意，为正确答案。in nature“实质上，性质上”，in return“作为回报”，in fact“实际上，事实上”。均不合题意。]
