问题
The research scientists often meet with problems________new types of instruments for solutions.
选项
A、require
B、to require
C、required
D、requiring
答案
D
解析
此处考查非谓语动词短语作后置定语,可首先排除A项。不定式作后置定语表示主动和将来;过去分词作后置定语表示被动或完成;现在分词作后置定语表示主动或正在进行。或者这个动作与谓语动词所表示的动作(几乎)同时发生。根据句意可知,problems与require之间是逻辑上的主谓关系,且句中没有明显的表示时间先后顺序的词,所以应用现在分词的一般式,表示主动。故选D。
