This is the VOA Special English Health Report.
ðɪs ɪz ðə vi-oʊ-eɪ ˈspɛʃəl ˈɪŋglɪʃ hɛlθ rɪˈpɔrt.
Cardiopulmonary resuscitation, or CPR,can save the life of someone whose heart has stopped.
kɑrdioʊˈpʊlməˌnɛri rɪˌsʌsɪˈteɪʃən, ɔr si-pi-ɑr, kæn seɪv ðə laɪf ʌv ˈsʌmˌwʌn huz hɑrt hæz stɑpt.
The condition is called cardiac arrest.
ðə kənˈdɪʃən ɪz kɔld ˈkɑrdiˌæk əˈrɛst.
The heart stops pumping blood. The person stops breathing.
ðə hɑrt stɑps ˈpʌmpɪŋ blʌd. ðə ˈpɜrsən stɑps ˈbriðɪŋ.
Without lifesaving measures, the brain starts to die within four to six minutes.
wɪˈθaʊt ˈlaɪfˌseɪvɪŋ ˈmɛʒərz, ðə breɪn stɑrts tu daɪ wɪˈðɪn fɔr tu sɪks ˈmɪnəts.
CPR combines breathing into the victim's mouth and repeated presses on the chest.
si-pi-ɑr kəmˈbaɪnz ˈbriðɪŋ ˈɪntu ðə ˈvɪktəmz maʊθ ænd rɪˈpitɪd ˈprɛsəz ɑn ðə ʧɛst.
CPR keeps blood and oxygen flowing to the heart and brain.
si-pi-ɑr kips blʌd ænd ˈɑksəʤən ˈfloʊɪŋ tu ðə hɑrt ænd breɪn.
However, a new Japanese study questions the usefulness of mouth-to-mouth breathing.
ˌhaʊˈɛvər, ə nu ˌʤæpəˈniz ˈstʌdi ˈkwɛsʧənz ðə ˈjusfəlnəs ʌv maʊθ-tu-maʊθ ˈbriðɪŋ
The study was published in the British medical magazine,The Lancet.
ðə ˈstʌdi wʌz ˈpʌblɪʃt ɪn ðə ˈbrɪtɪʃ ˈmɛdəkəl ˈmægəˌzin, ðə ˈlænsət.
Doctors in Tokyo led the research. It examined more than four thousand people who had suffered cardiac arrest.
ˈdɑktərz ɪn ˈtoʊkiˌoʊ lɛd ðə riˈsɜrʧ. ɪt ɪgˈzæmənd mɔr ðæn fɔr ˈθaʊzənd ˈpipəl hu hæd ˈsʌfərd ˈkɑrdiˌæk əˈrɛst.
In all the cases, witnesses saw the event happen.
ɪn ɔl ðə ˈkeɪsəz, ˈwɪtnəsəz sɔ ði ɪˈvɛnt ˈhæpən.
More than one thousand of the victims received some kind of medical assistance from witnesses.
mɔr ðæn wʌn ˈθaʊzənd ʌv ðə ˈvɪktəmz rəˈsivd sʌm kaɪnd ʌv ˈmɛdəkəl əˈsɪstəns frʌm ˈwɪtnəsəz.
Seven hundred and twelve received CPR. Four hundred and thirty-nine received chest presses only.
ˈsɛvən ˈhʌndrəd ænd twɛlv rəˈsivd si-pi-ɑr. fɔr ˈhʌndrəd ænd ˈθɜrdi-naɪn rəˈsivd ʧɛst ˈprɛsəz ˈoʊnli.
No mouth-to-mouth rescue breaths were given to them.
noʊ maʊθ-tu-maʊθ ˈrɛskju brɛθs wɜr ˈgɪvən tu ðɛm.
The researchers say any kind of CPR improved chances of the patient's survival.
ðə ˈrisərʧərz seɪ ˈɛni kaɪnd ʌv si-pi-ɑr ɪmˈpruvd ˈʧænsəz ʌv ðə ˈpeɪʃənts sərˈvaɪvəl.
But,they said those people treated with only chest presses suffered less brain damage.
bʌt, ðeɪ sɛd ðoʊz ˈpipəl ˈtritəd wɪð ˈoʊnli ʧɛst ˈprɛsəz ˈsʌfərd lɛs breɪn ˈdæməʤ.
Twenty-two percent survived with good brain ability.
ˈtwɛnti-tu pərˈsɛnt sərˈvaɪvd wɪð gʊd breɪn əˈbɪləti.
Only ten percent of the victims treated with traditional CPR survived with good brain ability.
ˈoʊnli tɛn pərˈsɛnt ʌv ðə ˈvɪktəmz ˈtritəd wɪð trəˈdɪʃənəl si-pi-ɑr sərˈvaɪvd wɪð gʊd breɪn əˈbɪləti.
The American Heart Association changed its guidelines for CPR chest presses in two thousand five.
ði əˈmɛrəkən hɑrt əˌsoʊsiˈeɪʃən ʧeɪnʤd ɪts ˈgaɪˌdlaɪnz fɔr si-pi-ɑr ʧɛst ˈprɛsəz ɪn tu ˈθaʊzənd faɪv.
It said people should increase the number of chest presses from fifteen to thirtyfor every two breaths given.
ɪt sɛd ˈpipəl ʃʊd ˈɪnˌkris ðə ˈnʌmbər ʌv ʧɛst ˈprɛsəz frʌm fɪfˈtin tu ˈθɜrdi fɔr ˈɛvəri tu brɛθs ˈgɪvən.
Gordon Ewy is a heart doctor at the University of Arizona College of Medicine in Tucson.
ˈgɔrdən ˈevi ɪz ə hɑrt ˈdɑktər æt ðə ˌjunəˈvɜrsəti ʌv ˌɛrɪˈzoʊnə ˈkɑlɪʤ ʌv ˈmɛdəsən ɪn ˈtuˌsɑn.
He wrote a report that appeared with the study.
hi roʊt ə rɪˈpɔrt ðæt əˈpɪrd wɪð ðə ˈstʌdi.
Doctor Ewy thinks the CPR guidelines should be changed again.
ˈdɑktər ˈevi θɪŋks ðə si-pi-ɑr ˈgaɪˌdlaɪnz ʃʊd bi ʧeɪnʤd əˈgɛn.
He said the heart association should remove rescue breaths from the guidelines.
hi sɛd ðə hɑrt əˌsoʊsiˈeɪʃən ʃʊd riˈmuv ˈrɛskju brɛθs frʌm ðə ˈgaɪˌdlaɪnz.
He argues that more witnesses to cardiac arrests would provide treatment if rescue breaths are not a part of CPR.
hi ˈɑrgjuz ðæt mɔr ˈwɪtnəsəz tu ˈkɑrdiˌæk əˈrɛsts wʊd prəˈvaɪd ˈtritmənt ɪf ˈrɛskju brɛθs ɑr nɑt ə pɑrt ʌv si-pi-ɑr.
He says this would save lives.
hi sez ðɪs wʊd seɪv lɪvz.
Studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease.
ˈstʌdiz ʃoʊ ðæt ˈmɛni ˈpipəl du nɑt wɑnt tu pərˈfɔrm maʊθ-tu-maʊθ ˈbriðɪŋ ɑn ə ˈstreɪnʤər fɔr fɪr ʌv ˈgɛtɪŋ ə dɪˈziz.
Cardiac arrest kills more than three hundred thousand people in the United States every year.
ˈkɑrdiˌæk əˈrɛst kɪlz mɔr ðæn θri ˈhʌndrəd ˈθaʊzənd ˈpipəl ɪn ðə juˈnaɪtəd steɪts ˈɛvəri jɪr.
The American Heart Association says about ninety-five percent of victims die before they get to a medical center.
ði əˈmɛrəkən hɑrt əˌsoʊsiˈeɪʃən sɛz əˈbaʊt ˈnaɪnti-faɪv pərˈsɛnt ʌv ˈvɪktəmz daɪ bɪˈfɔr ðeɪ gɛt tu ə ˈmɛdəkəl ˈsɛntər.

信息和事实（Facts）：
跟读原音找语调和节奏。
感受与评价（Comments）：
上课的时候听S根据感觉似乎也不难的样子，但自己一跟读就知道还是练习得不够，有时候觉得自己读得还可以了也只是一种错觉而已，就像S说了，坚持了这一个月是进步了不少，但接下来呢，再读个几天然后放弃吗？还是坚持练下去，把这篇材料练透练通，练到跟读、视译、听译都没有任何问题？
真的从来没有拿着这样一份材料一点点磨得如此透彻，那就持续下去吧，看看能一篇材料练到自己内化吸收会有什么收获。
