　　The speaker refutes the reading's argument about the benefits of adding fluoride to pipe water by providing contradictory evidence about pipe water's fluoride's effectiveness in preventing cavities in teeth, killing bacteria, and decreasing bone diseases.

　　Firstly, the speaker points out that the short contact of fluoride with teeth will not enable the fluoride to prevent cavities, as the reading argues. Instead, the water will pass the mouth and teeth quickly and go directly to the stomach.

　　Another argument raised in the lecture is that fluoride could undergo chemical reactions with heavy metals in the pipe, such as lead. This will create toxic substances which will pose serious health threat. In this way fluoride could be even more deadly than bacteria. Although the fluoride, as the reading says, will kill some bacteria, the cure here is worse than the disease.

　　In the end, the speaker maintains that overdose of fluoride will backfire to human bones. Although the reading illustrates that fluoride will improve bone strength, the lecture says overdose will cause serious damage to human bones.

　　九、托福综合写作满分范文：伦勃朗的油画

　　The lecture revises the idea presented in the text, that Rembrandt was not the artist who painted the famous painting "Portrait of an Elderly Woman in a White Bonnet”.

　　The inconsistency between the white cap, which identifies the woman as a servant, and the expensive fur collar she wears dissolves as the Professor explains that the fur collar was apparently painted over the original painting to increase its worth by displaying an aristocratic woman.

　　In addition, the assumption that light and shadow in the painting do not fit together is refuted by the fact that in the original painting, the woman wears a light cloth that illuminated her face. Thus the presentation of light and shadow was indeed very realistic and accurate, as it is characteristic of Rembrandt’s paintings.

　　Finally, the mystery of the panel consisting of patches glued together is also solved in the lecture. Actually, the wood panel was later enlarged to make it more grand and valuable, but the original painting was painted on a single panel, as Rembrandt would have done it. Furthermore, the wood is of the same tree used in other Rembrandt paintings, like the "Self-Portrait with a Hat”.

　　All the information point out that Rembrandt is the painter of the controversial painting.

　　十、托福综合写作满分范文：关于恐龙是否是恒温动物

　　The professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms i.e. they were not able to keep their body temperature at a constant rate.

　　The professor contradicts the issue of dinosaurs being endothers based on the availability of fossils being available in thwe polar regions, she say that the polar regions in those days were not as cold as they are today i.e at least warm enough for dinosaurs to live. Durin harsh winters she says that there is a possibility of the dinosaurs actually migrating to warmer regions.

　　The issue of leg position and movement being used as a reason to clasify the dinosaurs as endotherms does not please the professor either. She says that dinosaurs had legs under their bodies to support their huge bodies i.e the legs under the body of the dinosaur were actually to support the huge weight of the dinosaur and not to provide it with a body structure like endotherms(which is actually suited for running).

　　The professor acknowledges the presence of haversian canals but also points out that that the fossils show the presence of growth rings. These rings occur due to the thickening of the bone. The thickening indicates that the dinosaurs were'nt actually growing continuously but were experiencing periods of rapid growth and periods of no growth in succesion.

　　This pattern. she says is characteristic of non endothermic aanimals. Thus it can be inferred that the professor challenges the passage by giving reasons as to why she thinks that the dinosaur is not an endotherm.
