单选题
Stylistic differences are available to all mature native speakers and in literate communities to all writers, as well as to foreigners who know a second language realty well. But there is undoubtedly a considerable range of skills in ______ all the resources of a language.
【正确答案】
A
【答案解析】[解析] 首先，从该句空前a considerable range of skills in和空后的宾语all the resources of a language，从语法角度判断应为动词的现在分词，而C和D与该句的语境格格不入；第二，该句的语境在讲“语言的运用”，所以只有A项的动词exploiting为正确选择。
