TPO 第13套 综合写作题目重新选题
Private collectors have been selling and buying fossils, the petrified remains of ancient organisms, ever since the eighteenth century. In recent years, however, the sale of fossils, particularly of dinosaurs and other large vertebrates, has grown into a big business. Rare and important fossils are now being sold to private ownership for millions of dollars. This is an unfortunate development for both scientists and the general public.
The public suffers because fossils that would otherwise be donated to museums where everyone can see them are sold to private collectors who do not allow the public to view their collections. Making it harder for the public to see fossils can lead to a decline in public interest in fossils, which would be a pity.
More importantly, scientists are likely to lose access to some of the most important fossils and thereby miss out on potentially crucial discoveries about extinct life forms. Wealthy fossil buyers with a desire to own the rarest and most important fossils can spend virtually limitless amounts of money to acquire them. Scientists and the museums and universities they work for often cannot compete successfully for fossils against millionaire fossil buyers.
Moreover, commercial fossil collectors often destroy valuable scientific evidence associated with the fossils they unearth. Most commercial fossil collectors are untrained or uninterested in carrying out the careful field work and documentation that reveal the most about animal life in the past. For example, scientists have learned about the biology of nest-building dinosaurs called oviraptors by carefully observing the exact position of oviraptor fossils in the ground and the presence of other fossils in the immediate surroundings. Commercial fossil collectors typically pay no attention to how fossils lie in the ground or to the smaller fossils that may surround bigger ones.
Summarize the points made in the lecture, being sure to explain how they support/contradict specific points made in the reading passage.
Point 1: It will be harder for the public to see fossils, which would be a pity.
Point 2: Scientists are likely to lose access to some of the most important fossils and thereby miss out on potentially crucial discoveries about extinct life forms.
Point 3: Commercial fossil collectors often destroy valuable scientific evidence associated with the fossils they unearth.
Point 1: The public is more likely to have exposure to fossils, because commercial fossil hunting makes a lot of fossils available for purchase.
Point 2: Even if a fossil is destined to go to a private collector, it has be examined by scientific experts first. So the scientific community is not going to miss important things.
Point 3: Many fossils would simply go undiscovered without the private collectors.
