【題目】__________ people in the world are sending and receiving e-mails every day.

A.Million ofB.Several million of

C.Millions ofD.Several millions

【答案】C

【解析】

句意:世界上有數(shù)百萬(wàn)人每天都在收發(fā)電子郵件。

考查數(shù)詞。當(dāng)具體的數(shù)詞修飾million時(shí),用單數(shù),如five million workers五百萬(wàn)工人;當(dāng)million后面跟有介詞of時(shí),必須加上s。由此可知AB、D選項(xiàng)均錯(cuò)誤,只有C選項(xiàng)符合題意,millions of數(shù)百萬(wàn)的,表示不確切的數(shù)字,故答案選C。
