--How many of the books have you read?

-- ___________ . It's said that these books are all very boring.

A. All

B. None

C. No one

D. Everything

【答案】

B

【解析】

句意：——这些书你读过多少本？——没有一本。据说这些书都是非常无聊的。All三者说三者以上都；none表示三者或三者以上都不；no one没有人；everything一切。根据It's said that these books are all very boring.可知此处表示这些书都是无聊的，因此没有读过一本，故用none。故选B。
