【题目】William Shakespeare is generally believed ______ all plays himself.
A.to writeB.to have writtenC.writingD.writing
在线课程【答案】B
【解析】
考查非谓语动词。句意：人们普遍认为莎士比亚所有的戏剧都是他自己创作的。固定句型是：sb. is believed to do sth.(人们认为某人要去做某事)，sb. is believed to have done sth.(人们认为某人做过了某事)。结合题意，莎士比亚的戏剧是过去创作的。所以B. to have written
符合题意。故选B项。
