again,从我学语言学的朋友那里打听的。
Here is her reply:
If I am right, I think it should be "t" [t] in "attract" that goes weak rather than [k]. In linguistic terms, the sound that seems unpronouned is called "unreleased." 也就是说t比k发音更弱。泡泡说的无比正确。
长元音的问题:
不是轻辅音前短读,而是一般说浊辅音前长读。(结果是一样的。)这是不需要刻意记的,因为发音机制自动需要更长的时间才能读出浊音。轻辅音声带不振动,而元音和浊辅音都需要声带振动,发音器官到位需要时间。
