选择题
The tsunami killed people in south and southeast Asia.
A．ten thousands
B．ten thousands of
C．tens of thousand
D．tens of thousands of
答案
答案：D
英语中如hundred,thousand,million,billion等概数词修饰名词时，若前面用了基数词，不论后面有没有of，都必须用单数形。但若前面没有准确的数字而后面有of时，则一定用复数形，表示数量之大。注意表达:thousands of+名词或数字+thousand+名词或tens of thousands of+名词。
