否定描述
There is(are) no...
S+ have no...
S+ don't have...
以上三種用法的差別很小，語意嚴格來分的話，「There is not」是一種客觀狀態的敘述，而「S. have no 」以及「S. don't have」是一種所有權的敘述。
比如說，如果你說「我沒有錢可以借你」，這句的重點其實是「所有權」，因為「錢是我的」，所以造句就要用第二或第三種句型：
I have no money to loan you.
I don't have money to loan you.
兩句意思完全一樣。
ex.
We have no money.
We don't have money.
We don't have much money.
You don't have any hair.
肯定描述
There are three people in my family.
My family has three people.
