Question

Robert is said________ abroad, but I don’t know what country he studied in.

A．to have studied	B．to study
C．to be studying	D．to be studied

Answer 1

A

试题分析：句意：据说罗伯特曾经在国外学习，但是我不知道他曾经在哪个国家学过。这里主要考查用动词不定时的什么形式，根据what后的从句的谓语动词studied可知，学习放生在过去，现在已经不在那里学习了，又因为is said与study abroad动作的先后来看，应是先发生study abroad，所以表示非谓语动词的动作先于谓语动词的动作，需用不定式的完成时，故选A。
点评：本题难度适中。非谓语动词是高考常考的知识点，它的各种形式的用法，是高中阶段的难点，提醒考生要理解不同形式的用法及意义。
即学即练：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：考查动名词短语和不定式短语作宾语时的区别。即：mean＋to do意为“打算/想要做……”;mean doing意为“意思是……；意味着……”。由句意可知应选B。
