Very interesting,such as playing a game!

You have three options to learn new words.if you are tiered of using one,you can change it!you learn how to use them in sentences.if you dont know the meaning,you can guess from the example and it makes you eager more to continue when the answer is true.at last,you learn new wordes in useful fields that you need more.good luck
