在桌子上有个电脑（英语中谁在前面就强调谁）：
There is a HR.【这有一个HR】
On the desk there is a computer.【强调电脑在桌子上，不在其他地方，所以on ther desk在前面】
There is a computer on the desk.【强调桌子上有电脑，而没有其他东西，所以there is a computer在前面】
《The Godfather》
Behind every great fortune there is a crime.
《TOM SWIFT AND HIS SUBMARINE BOAT》
There was a rushing, whizzing, throbbing noise in the air.
There was a mystery connected with the boat.
There was a scuffle, and the next minute Tom cried out:"What are you doing here?".
There are a number of contestants.
由此可见，尾部都是名词性的内容
