(2005上海） A. sitting B. having sat C. to sit D. sat 　解析： 此题大家易受习惯心理影响选择分词，即 Ａ或Ｂ项，而and实际上作为并列连词并列的 是found及sat两个动作，而非并列providing与 sitting. 例② Prices of daily goods _____ through a computer can be lower than store prices. A. are bought B. bought C. have been bought D. buying 解析：此题学生最易错选的答案为Ａ或Ｃ。依据上面陈述，填入Ａ或Ｃ句子都有两个谓语动词，而此处两个动词并非并列谓语，也不是分别出现在主从句中，故答案有误。该题正确答案为Ｂ，bought through a computer为一过去分词短语作后置定语，句中只有一个谓语can be lower than。当然此题如改为Prices of daily goods which have been bought through…也是正确的，因为这一动作出现在从句中。 小试牛刀 1).

(06山东) A. being given B. is given C. given D. was given 二、考查非谓语动词作主语 能作主语的非谓语动词有不定式和动名词。二者的 区别是：表示某一具体的动作时，多用不定式；表示比 较抽象的一般行为倾向的，多用动名词。动名词作主语 时通常位于句首；不定式作主语时常置于句末，用it 作形式主语放在句首。 1) Smoking is prohibited(禁止)here. 2) It is not very good for y
