BOB DOUGHTY: This is SCIENCE IN THE NEWS, in VOA Special English. I’m Bob Doughty.
FAITH LAPIDUS: And(不清楚原读是怎样处理的, 通常是轻,短) I’m Faith Lapidus. This week, we tell about vitamins (double check if it is pronounced as –mins, -mens).
BOB DOUGHTY: Many jobs must be done with two people(L音很弱, 可以加个O音, peop/ou/l, 这样足够的时间把舌尖顶一下上腭). One person takes the lead. The other helps. It is this cooperation(nothing wrong with this word, in order to make it sound more like a native speaker, 可以加个y音, cowaperation ) that brings success.
So it is with the human body. Much of our good health depends on the cooperation between substances (incorrect stress on /tance/). When they work together, chemical reactions take place smoothly. Body systems are kept in balance.
Some of the most important helpers in the job of good health are the substances we call vitamins
