问题补充：

Tony is said to New York, and now he is studying medicine in a famous college in America.

A. have gone

B. to have gone

C. going

D. to go

答案：

A. have gone

(答案→)B. to have gone

C. going

D. to go

解析：考查不定式用法。固定搭配be said to do sth据说做某事；如果该动作发生在谓语动作之前，就使用不定式的完成式；如果该动作与谓语动词的动作同时发生，就使用不定式的进行式；句意：据说Tony已经去了纽约，现在在美国的一所著名的大学里学习。根据句意说明Tony已经去了纽约了，这个动作发生在say之前，故使用不定式的完成式。故B正确。
