The katakana words on the left are real Japanese katakana words used in Japan. The romanization is to help you if you havn't memorized all the katakana symbols yet. Try to cover the English meaning and guess what it is first.
Some words though are tricky.
Department Store is just depaato, and Television is only terebi. One thing to remember is that not all Katakana words are taken from English. There are a few from other langauges so if you can't figure out a certain word that could be the reason. But most Katakana words sound similar to their English counterpart and usally can be easily sounded out. Read some real Japanese text and try to pick out Katakana English words.
