@dobiapps.com: Challenge: Daily Authentic English Speaking Practice - Day 257. The phrase is 'Are you mad at me?' which means '你生我气了吗？'. Let's break it down: 'Are you' forms a question. 'Mad' here is an adjective meaning angry (used in American English, not 'crazy'). The fixed expression is 'be mad at someone', meaning to be angry with someone. Important note on prepositions: use 'at', not 'to'. So, 'be mad at me' is correct, while 'be mad to me' is incorrect. #learnenglishfromscratch #hollywoodmovies #english #americandramas #englishspeaking
