One correction: Don’t pronounce 姐姐 as Jie2 jie like the teacher in the video. Pronounce 姐姐 as Jie3 jie (half third tone and neutral tone.)
For L2D2: 你爸爸妈妈做什么工作？
One correction: We don’t pronounce “g” sound in “Jingli” (Manager). Same thing–We don’t pronounce the “g” sounds in “gongchengshi” (engineer) or “jingli” (manager) or “yi sheng” (doctor) This teacher did a good job in general and has a good pronunciation except for these mistakes, so watch out for these mistakes.
