问题 He finished the task on his own,______effecting a considerable saving in time and money.

选项 A、thereafter
B、thereof
C、therefore
D、thereby

答案 D

解析 thereby doing sth.,意为“因此,由此,从而”,如:Diets that are high in saturated fat and cholesterol tend to clog up our arteries,thereby reducing the blood flow to our hearts and brains.高饱和脂肪和高胆固醇的饮食阻塞我们的动脉,因而减少了流人心脏和大脑的血液。
