“ Although ,” the boy said , “ _______ over and over , the maths problem remained confusing to me ” .
A．explainedB．explain
C．explainingD．having explained
A

試題分析：這題考查非謂語動詞和省略式，當主從句的主語一致時，可以省略從句的主語和be動詞，the boy said ,是插入語，暫且不看Although explained over and over=" Although" ,the maths problem was explained over and over，句意是：男孩說：雖然這個數(shù)學問題被解釋了一遍又一遍，它對我來說還是不理解。選A。
點評：英語的省略式的一種就是從句的省略，條件是主從句的主語要一致，然后考慮謂語和邏輯主語的關(guān)系，決定是現(xiàn)在分詞還是過去分詞。
