The American Heart Association changed its guidelines for CPR chest presses in 2005.

练习要点整理：
22%-Twenty-two 的音调，percent的重音，survived 的/v/咬唇，good注意发音靠后振动声带，brain的靠后浊化发音，ability的/ə/不是/eɪ/
Only的/oʊn/要有拼的感觉，victims的/t/带一点浊化，CPR语速放慢
The American的the 元音前面发/ði/,American /əˈmɛrəkən/发音要慢每个音要清晰，changed的/ʧeɪn/嘴型要到位，guidelines是/ ˈgaɪˌ/不是gay/ɡeɪ/,而guy也是/ɡaɪ/，要注意区分。
