1．He ________ to save the dying man，but failed.
A．managed B．attempted
C．risked D．assisted
答案 B [句意：他努力想把那个垂死的人救过来，但没有成功。attempt to do＝try to do。而manage to do表示“做成某事”；risk doing“冒险做”。]
2．When I visited her，she was ________ in writing a lecture speech on Chinese History.
A．absorbing B．concentrated
C．devoted D．occupied
答案 D [动词辨析。be occupied in doing sth“集中精力”。其他三个词的用法为be absorbed in/ concentrate on/ devote...to，故在此处的结构不正确。]
