念作hundreds of millions of。
thousand、million、billion、trillion、dozen、score的用法如下:
一、这几个数词前面有具体数字时,不加-s,后面可以直接加名词,分别表示“千”、“百万”、“十亿”、“万亿、兆”、“十二”和“二十”的意思。如:
five thousand birds
five million dollars
ten billion yuan
one trillion baht
one dozen eggs
I have learned English for one score years.
二、这几个字前无明确数字时,要用复数形式后加of,表示概数,如:
thousands of birds
millions of dollars
billions of yuan
trillions of baht
dozens of eggs
I have learned English for scores of years.
希望我能帮助你解疑释惑。
