Materials:
In all the cases, witnesses saw the event happen. More than one thousand of the victims received some kind of medical assistance from witnesses.
Facts:
1. w 发音时舌后部向软腭抬起，但不要抵住；双唇收圆并向前突出，同时声带需振动。
2. h 发音时气流自由溢出口腔，只在通过声门时发出轻微摩擦；清辅音，发音时声带不振动，送气很大。
3. l 发音时舌尖紧贴上齿龈，舌前部抬起靠近硬腭；发音时气流从舌的两侧泄出，声带振动。
Light l: The tip of the tongue reaches up and touches the roof of the mouth just behind the front teeth as the vocal chords are making sound.
Dark l is made of 2 parts: the vowel-like sound and the l. The tip of the tongue pulls back a little bit. It doesn't touch anything. The tongue is raised somewhere towards the middle and the lips round a little bit before the tips of the tongue moves back to make the l sound.
Comments
今天是继上次两个傻傻分不清楚的音之后，第二次被虐得如此之狠。L的发音今天在上课的时候就听得云里雾里，下去的练习也没有让我明白它的发音要领。开始按照发音技巧去读，跟s上课的录音对比，发现并不一样。之后又经历了错发成卷舌的r和鼻音n的阶段，最后快崩溃的时候想起来去网上找找S截图的小姐姐的教程，听写了一下发音方法，再对着视频模仿了很久，终于有点感觉了。由于今晚娃不太给力，明天再继续练习。要享受被虐的感觉才能早日不再被虐！
