此題是考查非謂語(yǔ)動(dòng)詞嗎

有這樣一道題：

__________ many times，but the boys still couldn’t understand it.

A. Having told              B. Though he had been told    C. He was told              D. Having been told

現(xiàn)分析如下：

此題應(yīng)選C。容易誤選A，D，考生從四個(gè)選項(xiàng)中初看一眼便斷定此題是考查非謂語(yǔ)動(dòng)詞，這剛好落入了命題者的設(shè)置的陷阱。做好此題的關(guān)鍵點(diǎn)在于注意到句中的并列連詞but，因?yàn)樗�的存在就表明這是一個(gè)并列句，所以前面應(yīng)是一個(gè)完整的句子而不能是一個(gè)非謂語(yǔ)動(dòng)詞。
