你好，hundred 前面没有具体的数字，表示“数百”时，后面加s ，并和of 连用。eg.There are hundreds of students in the hall.礼堂里有数百名学拿纯粗生。 There are about six hundred students in the hall.礼堂里大约有六百名学生。裤蔽另外，thousand,million,billion的用法与hundred 一样。eg.The hill is covered with thousands of trees. You can see millions of stars in the sky. There are about two million books in our school library.希望能帮到你，祝消镇你开心。
