在線答疑、課后同類題練習(xí)、講義下載、短信提醒原則一、兩個句子必須要用連詞連接，如果沒有連詞連接，則需要用非謂語動詞
例1. _________ many times, but he still couldn’t understand it.
A. Having been told B. Having told C. He had been told D. Though he had been told
例2._________ many times, he still couldn’t understand it.
A. Having been told B. Having told C. He had been told D. Though he had told
解析：例1中有連詞but連接，表明前后都是句子，所以答案為C。
例2中后面是一個句子，而且沒有連詞，所以前面不是句子，應(yīng)該用非謂語動詞，根據(jù)句意此處為被動，所以答案為A。
