原材料引用(Material):
Seven hundred and twelve received cpr. Four hundred and thirty nine received chest presses only. No mouth to mouth rescue breaths were given to them.
信息和事实(Facts):
/j/ 双唇微开,舌抵下齿贴近硬腭,气流摩擦而出;
/u:/ 双唇成圆形,牙床近于半合,舌尖不触下齿,自然而不用力,发 “屋”之长音。 是字母oo或ou在单词中的发音。
感受与评价(Comments)
“ breaths” 读起来舌头像打结,听了原音很多次了,发不好这个音。
统计累计的练习小时数(Hours):(这里单指整句练习时间。单个发音是随时随地练的,不方便计时。
