2019年mpacc考试英语真题——连词33

{01}I was very cold ________ they still went swimming．

C.but
D.because
解析：
本题选C。
{02}The aim is hard to arrive at; ________, it is worth doing so．
A.besides
B.however
C.otherwise
D.though
解析：句意：这一目标很难达到，但是还是值得一试。所以上下句的关系是转折关系，用however。besides“除此之外，而且”，表示增补关系；otherwise“否则，要不然”，表示选择关系；though“尽管如此”，表示让步关系。所以答案为B项。
本题选B。
