– There’s somebody at the door. Who ____ it be? Is it the postman?
-- No. It ______ be him. It’s just seven o’clock. It’s too early.| A．must, may not | B．will, won’t | C．may, mustn’t | D．may, can’t |
|
答案
| D |
解析
| “有人敲门，会是谁呢?是邮差吗?不，不可能是他，才7点，太早了。”may用于推测，用在疑问句和否定句中表示“可能，可以”，will 表示“将要”，而must 表示“必须，肯定”的意思，故第一空用may；第二空can’t 表示否定的推测“肯定不是，一定不是”，而mustn’t表示不准的意思，不适合。所以正确答案是D。 |
