There're over 20 ---------- living in Tokyo.答案是millions of p

答案肯定是错的.
应该是：million people.
再问： 这是一道选择题 A.million of people B.millions of people C.millions of peoples D.millions people 我查了好几个网站，答案都给的是B，所以就凌乱了。。
再答： 以下都是正确的表达： 1 There are millions of people living in Tokyo 2 There are (about / over / more than / less than / up to ) 20 million people living in Tokyo. 3 There are （over）20 million OF THE Japanese people living in Tokyo. 4 以上都是“数词+名词”的结构，超出它们范围的应该就是错的了。祝你愉快。
