小薇讀得很好！小磚渣見內。

BOB DOUGHTY: This is SCIENCE（IE之間應該有個小y的音） IN THE NEWS, in VOA Special English. I’m Bob Doughty（似乎聽到r音？）.

FAITH LAPIDUS: And I’m Faith Lapidus. This week, we tell（l的發音，應該是舌頭觸及上頜膛的） about vitamins.

(MUSIC)

BOB DOUGHTY: Many jobs must be done with two people. One person takes the lead. The other helps. It is this cooperation that brings success.

So it is with the human body. Much of our good health depends on the cooperation between substances. When they work together（再讀地連貫些更好）, chemical reactions take place smoothly. Body systems are（沒卷舌） kept in balance.

Some of the most important helpers in the job of good health are（沒卷舌） the substances（似乎subs的第二個s和tances的t距離遠了一些。） we call vitamins.
