Can someone tell me how to write an article review in apa style?

If you go to this website you may find out what you need: Bedford/St. Martin's

bedordstmartins.com is a website that explains the APA style, but I don't think its free. Check it out and see. :)

Your library may very well have the resources you need. If this style is a style you will use often, consider purchasing the book. It will always come in handy.
