How old are the apps on your smartphone? Is it time for an update? Here are three apps for you. Try them out and have fun.
Duolingo
Learning a foreign language doesn’t always mean you have to sit in a class and take endless exams. An app called Duplingo has been designed to help you memorize(记住)new words and grammar in creative ways, such as online lessons, games and interesting exercises. For example, one exercise asks you to put words in the right order to make the correct sentence. You can also try translation practice.
Douban FM
A music app is a necessity for almost every smartphone now. Douban FM might be the right thing for you.
There is no playlist on Douban FM—songs just keep streaming(播放)one by one. You can use the “heart”, “trash” and “skip” buttons(按钮)to mark the songs you like, don’t like and want to cut short, respectively(分别地). Those marked with a heart will be stored in another list as your favorites for you to listen to anytime you want. Douban FM also has different channels (频道). There are many types of music, such as blues, jazz, and pop. You can choose the music for outdoor activities, work or studying depending on your mood（心情）.
