托福综合写作范文Topic 议题关于Gustave Whitehead 先于莱特兄弟成功试飞飞机
	Reading	Listening
Thesis 总论点	The whitehead’s test flight did not succeed.	The messages mentioned in the reading are misleading.
Sub-point1 分论点1	The report about that flight test was not convincing for it only had some draft drawings, without any correspondent photos.	The reason why the report had no photo lied in two aspects. First, the photography technology at that time was not as advanced as it is now. As the imaging techniques was not good, the quality of the photos was low. In addition, when the experiment was conducted, it was cloudy; in such condition to capture the image of a flying plane was too difficult.
Sub-point2 分论点2	The design of Whitehead’s plane that only had one wing was not logical, for the plane usually had two or three wings at that time.	In the recent, some researchers have made a copy of Whitehead’s plane based on his design diagram. They tested the copy planes four times, and each of them was successful.
Sub-point 3 分论点3	Whitehead had produced many engines and sold them to several aircraft builders, but in fact none of those engines used in the planes had ever succeeded, illustrating that Whitehead had not successfully tested his plane.	The problem that those engines did not work could not be blamed to Whitehead. It was because the technology was not so developed at that time and aircraft builders knew little about designing planes. The fact that there were people buying Whitehead’s engines actually proved that his design had no problem.

　　托福综合写作范文Sample answer:

　　The reading puts forward three reasons to illustrate the bad effects brought by those prairie dogs. However, the professor refutes these three strongly.

　　Firstly, the listening argues that the reason why the report had no photo but only draft drawings lied in two aspects. First, the photography technology at that time was not as advanced as it is now. As the imaging techniques was not good, the quality of the photos was low. In addition, when the experiment was conducted, it was cloudy; in such condition to capture the image of a flying plane was too difficult.

　　Secondly, the reading claims the design of Whitehead’s plane that only had one wing was not logical, for the plane usually had two or three wings at that time. However, the professor disagrees. In the recent, some researchers have made a copy of Whitehead’s plane based on his design diagram. They tested the copy planes four times, and each of them was successful.

　　Finally, the reading suggests that Whitehead had produced many engines and sold them to several aircraft builders, but in fact none of those engines used in planes had ever succeeded, illustrating that Whitehead had not successfully tested his plane. But the professor argues the problem that those engines did not work could not be blamed to Whitehead. It was because the technology was not so developed at that time and aircraft builders knew little about designing planes. The fact that there were people buying Whitehead’s engines actually proved that his design had no problem.
