Angular 2 - 当你想显示“1st”，“2nd”，“3rd”等时如何处理* ngFor？(Angular 2 - How to handle an *ngFor when you want to show “1st”, “2nd”, “3rd”, etc.?)

 我试图创建一个循环来显示几个div，介于一到七之间。 
 
 但是，每个div都会有一个<p> Pick your 1st photo </p> ，其中第一项将显示第一项，第二项2nd ，第三项3rd等。 
 
 我如何处理这样的事情？ 
 
<div *ngFor="let item of items">
  <p>Pick your ___ photo</p>
</div>
 
 谢谢 

I am trying to create a loop to show a few divs, between one and seven.
 
However, each div will have a <p> Pick your 1st photo </p>, where the first item will say 1st, the second 2nd, third 3rd, etc. 
 
How can I handle something like this?
 
<div *ngFor="let item of items">
  <p>Pick your ___ photo</p>
</div>
 
Thanks
