(资料图片)

The speaker raises serious counterarguments against the reading paragraphs by providing drastically different evidences regarding the effects of the advertisement, the impact of self-selecting medication, and the impact of trends in the pharmaceutical制药的 industry.

First, knowing more information from the ads will not necessarily help the patients make better-informed decisions, as the reading argues. On the contrary, patients, without professional training and knowledge, will be more susceptible易受影响的 to misunderstanding information. For example, they would focus only on the positive sides of a certain medicine while ignoring the serious side effects.

In addition, if the patients bear the responsibility of prescribing开药，吩咐用药 their own medication, they assume more responsibility to their own health. This makes doctors less liable for potential潜在的 risks and undesirable consequences.

Lastly, as for the new trends" benefits to the patients, the speaker does not challenge the reading directly. Instead, he argues that the new medicine, which will count for most of the ads may not necessarily be the best medicine, even though the patients can inform their doctors about the new products.

托福英语作文范文-网络问卷：

The speaker questions the effectiveness of web based surveys by providing evidences contradictory to the reading.

First, he identified the reading"s logical flaw in assuming that an increase in the scope and quantity of the survey will automatically translate to greater precision of the surveys. However, if surveys aim to question people over 60 years old, how can these old people conduct surveys online since this group seldom surf the Internet? The web surveys are effective in reaching mainly the young generation. Thus the results cannot be extended to demonstrate the views of the whole population.

Second, although the web-based surveys will lower paper cost, they will inevitably incur new costs in web designing, flashy features, and other elements, which will require more costly team work. This evidence effectively attacks the reading"s argument that web surveys will certainly reduce the cost of the survey.

In the end, many web designers tend to overdo in the webpage and add fancy and flashy features. As a result, many people perceive the web-based surveys as not serious and are thus not willing to respond to the surveys. Unlike physical surveys that draw attention effectively, many web based surveys are simply ignored or even deleted.

托福英语作文范文-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.

托福英语作文范文-加氟自来水

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.

First, 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
