A．two hundreds B．two hundreds of C．two hundred D．hundred of 【答案】C 【详解】句意：在周末，人民公园里大约有两百人。 考查数词用法。two hundreds错误表达，hundred前有具体数字时不加s；two hundreds of错误表达；two hundred两百；hundred of错误表达，表示“数百”时需用hundreds of。根据句意和选项可知，此处表示“两百人”，用“two hundred”。故选C。 6．—It is Mum’s ________ birthday next Wednesday.

A．millions; million of B．million; millions of C．millions; millions of D．million; million of 【答案】B 【详解】句意：这位著名歌手已经卖出了一千万张唱片，成千上万的人非常喜欢听他们的歌。 考查数词million的用法。million百万，与具体数字连用时，习惯上用单数；不与具体数字连用，表示不确定的泛指数时，则不仅要用复数而且要后接介词of，构成短语“millions of”表示“成千上万的”。根据第一空数词“ten”可知用单数；第二空没有具体数字，millions of符合句意，故选B。 16．May 1st is the ________ day of May.

A．53,210 B．532,010 C．532,100 【答案】A 【详解】句意：—— 你能写出“五万三千二百一十”这个数字吗？—— 可以，它是53,210。 考查数字的英文表达。在英文数字表达中，“fifty-three thousand”表示五万三千，即53,000 ；“two hundred and ten”表示二百一十，即210。将两部分合起来就是 53,000 + 210 = 53,210。所以“fifty-three thousand, two hundred and ten”对应的数字是 53,210，故选A。 21．The number of “4,389,030” can be read as ________. A．four million, three hundred and eighty nine thousand and thirty B．four million, three hundred eighty nine thousand and thirty C．four thousand, three hundred and eighty nine thousand and thirty D．four million, three hundred and eighty nine thousand and thirteen 【答案】A 【详解】句意：数字“4,389,030”可以读作four million, three hundred and eighty nine thousand and thirty。 考查数词。根据英语的数字读法，首先应该分节，每三位数分一个节，从右往左；千位后的部分若不足百位，需加and连接，4,000,000读作“four million”；389,000读作“three hundred and eighty nine thousand”（百位与十位间加and）；30读作“thirty”，只有选项A符合题意。故选A。 22．How do you read 6,425,200?
