2019年mpa考试英语真题——连词972

{01}(2010·新课标全国)Mary made coffee ________ her guests were finishing their meal. A.so that B.although C.while D.as if 解析：考查状语从句中连词的选择。句意：趁客人们正在吃饭，玛丽煮好了咖啡。while表示“在……期间”，符合语意。
本题选C。
{02}________ several times，but he still doesn"t know how to do it correctly. A.Although I"ve taught him B.I"ve taught him C.Having been taught D.Having taught 解析：although不能与but连用，故不能选择A。若选C，必须把并列连词but去掉，这样就变成了一个简单句，为现在分词短语作让步状语。
本题选B。
