There are lots of questions out there. Okay, what we mean is that there are lots of ways to form questions out there. Luckily, English and Spanish form questions pretty similarly...but there are still some differences.
First-time ELLs tend to have trouble forming questions—especially yes/no questions. This is because in English, words are moved around differently.
These sections give step-by-step directions on how to form all question types in English—in case you haven't quite gotten it by listening alone. They don't teach you this in school, ELLs.
