这个do you suppose可以不看

“I haven’t heard from Henry for a long time.” “What do you suppose _________ to him?”

A. was happening                        B. to happen                        C. has happened                        D. had happened

【分析】此题容易误选B，认为动词 suppose 后接动词用不定式。正确答案应是C，其中的 do you suppose 是插入成分。请看以下类例情形（答案均选D）：

(1) Who do you think _________ the money?

A. to steal                      B. stealing                      C. to have stolen            D. stole

(2) What do you suppose _________ him think so?

A. to make                     B. making                      C. to have made             D. made

(3) Who do you guess _________ to the station to meet her?

A. to go                         B. going                        C. to have gone              D. went

(4) What do you imagine _________ him from going?

A. to prevent                  B. preventing                 C. to have prevented       D. prevented

以下各例中的 do you think (suppose, imagine, guess, etc) 也是插入成分，但其后接的句子用陈述句词序：

Who do you think he will marry? 你认为他会同谁结婚？

What do you think we should give her? 你认为我们该给她点什么呢？

When do you believe he will come? 你认为他会什么时候来？

What do you guess he wants to buy? 你猜他想买什么呢？
