試題分析：句意：據(jù)說羅伯特曾經(jīng)在國(guó)外學(xué)習(xí)，但是我不知道他曾經(jīng)在哪個(gè)國(guó)家學(xué)過。這里主要考查用動(dòng)詞不定時(shí)的什么形式，根據(jù)what后的從句的謂語(yǔ)動(dòng)詞studied可知，學(xué)習(xí)放生在過去，現(xiàn)在已經(jīng)不在那里學(xué)習(xí)了，又因?yàn)閕s said與study abroad動(dòng)作的先后來(lái)看，應(yīng)是先發(fā)生study abroad，所以表示非謂語(yǔ)動(dòng)詞的動(dòng)作先于謂語(yǔ)動(dòng)詞的動(dòng)作，需用不定式的完成時(shí)，故選A。
點(diǎn)評(píng)：本題難度適中。非謂語(yǔ)動(dòng)詞是高考�？嫉闹�識(shí)點(diǎn)，它的各種形式的用法，是高中階段的難點(diǎn)，提醒考生要理解不同形式的用法及意義。
即學(xué)即練：There’s a man at the reception desk who seems very angry and I think he means __________ trouble.
A. making　          B. to make       C. to have made         D. having made
解析：B。句意：考查動(dòng)名詞短語(yǔ)和不定式短語(yǔ)作賓語(yǔ)時(shí)的區(qū)別。即：mean＋to do意為“打算/想要做……”;mean doing意為“意思是……；意味著……”。由句意可知應(yīng)選B。
