Mann is not exclusive.Only about 5 percent to 13 percent of breast-fed babies received Vitamin D supplements between 2005 and 2007，according to a study published in April.These low numbers might stem from the misunderstanding that breast milk contains everything the baby needs，experts say.

　　“I think that the opinion that ‘breast is best’ leaves people just giving the breast milk and thinking that there isn’t anything else that the breast milk might be missing，” said Dr.Joyce Lee，a pediatric endocrinologist(内分泌专家)．

　　And recent surveys indicate less than half of pediatricians are recommending Vitamin D supplements to breast-fed babies，another possible reason for the low numbers.

　　60．What can we learn from the passage?

　　A．More and more women in the world prefer to the breast-feeding their children.

　　B．Actually breast milk contains all the nutrition that a child needs.

　　C．The breast milk is lacking of Vitamin D，which is not known by most mothers.

　　D．The infants can get directly the Vitamin D from the Sunlight without any damage to their health.

　　解析：选C。细节理解题。根据文中第三段的第1句话“But what Mann didn’t know was breast milk — considered the best source of nutrition for babies —is low in Vitamin D．”可知，母乳中维生素D的含量很低，这一点，Mann并不知道；故C项正确。
