问题描述：
hundred of 、thousand of、million of 、billion of 如果运用在句子中,要不要加“s”呢
eg:there are hundreds of people 这里hundred 加了s 但名词没加s
i have a couple of thousand pounds in the bank.i can afford the precious piano.这里thousand没有加s但后面的名词加了s
Thousands of letters are never delivered because the addresses are incorrect.这里的thousand和 letter都加了s
能说说为什么吗
答
hundereds of 和 thousands of 的意思是很多...后面要跟名词的复数形式,由于people是不可数名词,所以后面不加s,而letter时可数名词所以后面要加s.第二句中,a couple of 是一对的意思加上后面的thousand意思就为2000,...
