单选题 The Minister of Finance is believed ______ of imposing new taxes to raise extra revenue.
A. that he is to think B. to think
C. that he is thinking D. to be thinking

【正确答案】 D
【答案解析】[解析] 本题考查的是非谓语动词中动词不定式作补语的用法。句子的意思是:人们认为财政部长正在考虑通过征收新税来增加政府的额外岁入。用动词不定式的现在进行时:to be doing,意为“正在考虑”。当句子的主语是it时,才会用It is believed that…的形式,所以A、C项可以排除,故正确答案是D选项。
