	Reading	Listening
Thesis 总论点	Point out three functions of the special shaped head.	Refute the three explanations mentioned in the reading passage.
Sub-point 1 分论点1	First, sharks with such shaped head turn around quickly.	This kind of shark can turn around quickly, but it is not because of the special head, but because of other factors such as skeleton. Besides young sharks were used in the previous experiment, thus the young also affected the result. Maybe the old ones with such special heads cannot turn around that quickly.
Sub-point2 分论点2	Second, such head helps improve the shark’s sensitivity to electricity field.	An experiment proved that all sharks with and without this special head have similar sensitivity to artificial electric field.
Sub-point 3 分论点3	Third, the head can be used as a weapon to hunt prey.	Sharks’ eyes are located at both sides of the hammerhead, which is risky for them to use hammerheads as weapons. Besides, there’s no evidence to prove that sharks ever used heads as weapons.

　　托福综合写作范文Sample answer:

　　The reading and listening discuss about the special functions of the hammer-shaped head of a kind of a shark. The passage mentions three functions. Whereas, the professor totally refutes the three points presented in the passage.

　　Firstly, the professor rebuts the reading’s first point that sharks with such shaped head turn around quickly. The professor claims that this kind of shark does turn around quickly, but it is not because of the special head, but because of other factors such as skeleton. Besides young sharks were used in the previous experiment, thus the young also affected the result. Maybe the old ones with such special heads cannot turn around that quickly.

　　Secondly, the professor contradicts reading’s second point that such head helps improve the shark’s sensitivity to electricity field. The professor mentions that an experiment proved that all sharks with and without this special head have similar sensitivity to artificial electric field.

　　At last, the passage states the third view that the head can be used as a weapon to hunt prey. However, the professor explains that Sharks’ eyes are located at both sides of the hammerhead, which is risky for them to use hammerheads as weapons. Besides, there’s no evidence to prove that sharks ever used heads as weapons.
