BOB DOUGHTY: This is SCIENCE IN THE NEWS, in VOA Special English. I’m Bob Doughty（似乎聽到兒話音，沒有r，不應該有兒話音的）.
FAITH LAPIDUS: And I’m Faith Lapidus. This week（長音i似乎不夠到位，應該是類似“一”的音）, we tell about vitamins.
(MUSIC)
BOB DOUGHTY: Many jobs must be done with two people. One person takes（/ei/沒發好，聽起來像/艾/的音，建議看美語正音） the lead. The other helps. It is this cooperation（兩個音節，似乎你miss了一個，愚公給我修改的回帖中有音標，你也聽聽dictionary.com）that brings success.
So it is with the human(u不到位。建議你練練元音） body. Much of our good health depends on the cooperation between substances. When they work together, chemical reactions take place smoothly. Body systems are kept in balance.
Some of the most important（沒有卷舌） helpers in the job of good health are the substances we call vitamins.（V似乎牙齒沒咬下嘴唇）
