　　托福综合写作范文Sample answer:

　　The reading puts forward three causes that can explain the low production of rhino in parks. However, the professor refutes these three strongly.

　　Firstly, the reading claims infertility results from the alfalfa and hay in animal fodder, which increasing rhino’s hormone. In contrast, the professor argues that infertility can be cured by regulating hormone.

　　Secondly, in the reading, it suggests rhinos develop foot disease for often walking on the hard surface. However, the professor disagrees. Advanced radiographic image equipment can detect the early anomaly of the bone and feet, which can heal the rhinos.

　　Finally, the reading suggests brain disorder in the newborn rhino makes them cannot live long. But the professor suggests that the reason for the little rhino’s brain disorder is that its mother is so old that it carries toxic chemical element. So letting younger rhino bear child is one of the solution.
