when的使用说明非谓语动词做时间状语，答案不可能是B，从scold与句子主语间的逻辑关系来看，应该是动宾关系，答案应该是D。
       
        (2)根据状语的功能选择不同的连词
        Careful surveys have indicated that as many as 50 percent of
        patient do not take drugs ___ directed.(1996.1)
        A. like B. so C. which D. as
        由上下文的意思可以看出，分词所做的是方式状语，连词应该是as。
       
        9) 非谓语动词的体
       
        非谓语动词中分词的体有完成体和进行体，即having done, having been done和being done，完成体只用于做状语的场合，而进行体可以用于做定语和做补足语。
        动名词的体也有having done, having been done和 being done的结构主要用于做主语和宾语的场合。
        不定式的体有to be doing 和to have done，主要用于pretend, happen, seem, appear, be said to等结构中。如：
        ① The man in the corner confessed to _____ a lie to the manager of the company.(1997.6)
        A. have told B. be told C. being told D. having told
        having told在句中做介词宾语，表示动作发生在谓语动词之前。
       
        ② I'd rather read than watch television; the programs seem ____ all the time.(1997.1)
        A. to get worse B. to be getting worse C. to have got worse D. getting worse
        从all the time的使用可以推断get worse是一个渐变过程，所以用不定式的进行体。
       
        ③ The speech _____ a lively discussion started.(1995.1)
        A. being delivered B. was delivered C. be delivered D. having been delivered
        该结构属于独立主格结构做时间状语，状语分词所表示的动作发生在谓语动词之前，所以应该用完成体，答案为D。
       
        10）动名词复合结构
       
        动名词符合结构可以做主语、宾语和表语，在对动名词的考查中总是将其逻辑主语包括进来，形成动名词的复合结构：
        ① _____ in an atmosphere of simple living was what her parents
        wished for.(1999.1)
        A. The girl was educated B. The girl educated
        C. The girl's being educated D. The girl to be educated
        本题涉及题眼比较多，A，为从句做主语，但缺少that，D为不定式做主语，但缺少for(for the girl to be educated)，B结构不能做主语，答案是C，为动名词的复合结构。
       
        ② Ann never dreams of _____ for her to be sent abroad very soon.
        A. there being a chance B. there to be a chance
        C. there be a chance D. being a chance
        介词后用动名词，表示存在时必须用there be句型，所以答案为A，这也是动名词复合结构，there为动名词的逻辑主语。
       
        ③ I don't mind _____ the decision as long as it is not too late.
        A. you to delay making B. your delaying making
        C. you delaying to make D. you delay to make (2000.1)
