问题 He had struggled in poverty for so many years, Jackson has really sharpened her ability to pinch pennies.
选项 A、He was struggling
B、Having struggled
C、He was been struggling
D、Struggled
答案 B
解析 答案是B。从本案例题干的语句成分来看，位于主语Jackson之前的语句是个导致Jackson has really sharpened…的状语，因此只能用having done…的句式，而非he had done…再举几个例子：“Having finished the job，all the clerks knocked off earlier than usual．”“Having realized that she had been going out with several guys at the same time，Frank decided to leave her．”“Not knowing what to do next，she went to her teacher and picked her brains．”。通过这些例句，我们不难看出主句的动作与之前状语的关系。
