BOB DOUGHTY: Many jobs must be done with two people. One person takes（ei音有点不到位) the lead. The other helps. It is this cooperation that brings success.
So it is with the human(a little off） body. Much of our good health depends on the cooperation between substances（a little off). When they work together, chemical reactions take place smoothly. Body(a little off) systems are kept in balance.
Some of the most important helpers in the job of good health are the substances we call vitamins.
