Toefl Integraled writing-Tyrannosaurs rex The listening content totally refutes the reading passage in the issue of whether the well-know dinosaur Tyrannosaurs rex (T. rex) is a scavenger or not. Both sides hold different perspectives. First of all, the author claims that T. rex is a scavenger due to the short forelimbs. Usually, the successful hunter such as tiger and lion possesses robust forelimbs which allow them to capture animals, yet the lecturer argues that strong forelimbs are not the prerequisite for being a outstanding hunter. Crocodile, for example, is a ferocious hunter always capturing preys without difficulty. Its forelimbs only provide propulsion and do not take part in prey. Second, the article asserts that T. rex has a massive tail which away from it's center of gravity and similar body structure (bone ratio) with elephant, proofing that T. rex is tardy and fails to be a agile hunter. But, author does not take the age into account. At that period, numerous dinosaurs are even slower than T. rex. Although those herbivore dinosaurs have tough skin as their shield, T. rex's sharp and long teeth can penetrate it. Third the reading passage states that T. rex feeds on corpse owing to the high ability of smell. Such crude conclusion is overthrown by speaker. The author uses Vulture which is also own an excellent sense of smell as a example to support his idea. But, obviously, vulture is the only last scavenger nowadays. Vulture can travel hundreds kilo-meter a day for searching carcasses. However, T. rex is not such a good traveler. On the other hand, T. rex needs considerable food to sustain its huge body while, vulture is relative small. So, it is not a convincing analogy in this case. After all, given the T. rex's need of food and forage ability as a scavenger, It is too week to indicate T. rex is a scavenger.
