Question

Despite their __________ of interest, Fleming kept trying to develop the chemical ___________ it would be safe and effective.

A．lacking; in order to	B．lack; so that
C．lack; so as to	D．lacking; so that

Answer 1

B

    
试题分析:考查名词和目的状语。根据their可知后面填名词lack，排除A、D选项；而in order to和so as to后面跟动词原形，so that引导目的状语从句， 由此可知B选项正确。.句意：尽管他们对此缺少兴趣，弗莱明坚持努力去研究这种化学物质，为的是让它更安全有效。
