2019年mba考试英语模拟题——连词752

{01}________scores of times, but Derek still couldn’t understand how to use past participle in a concrete situation. A.Having explained B.Having been explained C.Though it was explained D.It was explained 解析：因为有连词but，前面应是完整的句子，排除A,B; Though不能和but同时使用，所以选D。
本题选D。
{02}The report shows that we are making progress ________ we need to make greater efforts. A.but that B.but for C.however that D.no matter how 解析：考查连词。That we need to make greater efforts是show的第二个宾语从句，but表示转折关系.根据句意可知：那篇报道显示我们正在取得进步但是我们需要更大的努力。
本题选A。
