　Reading
　　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.
　　Listening
　　Professor:
　　Of course there are some negative consequences of selling fossils in the commercial market, but they have been greatly exaggerated. The benefits of commercial fossil trade greatly outweigh the disadvantages.
　　First of all, the public is likely to have greater exposure to fossils as a result of commercial fossil trade, not less exposure. Commercial fossil hunting makes a lot of fossils available for purchase, and as a result, even low-level public institutions like public schools and libraries can now routinely buy interesting fossils and display them for the public.
　　As for the idea that scientists will lose access to really important fossils, that's not realistic either.
　　Before anyone can put a value on a fossil, it needs to be scientifically identified, right? Well, the only people who can identify fossils, who can really tell what a given fossil is or isn't, are scientists, by performing detailed examinations and tests on the fossils themselves. So even if a fossil is destined to go to a private collector, it has to pass through the hands of scientific experts first. This way, the scientific community is not going to miss out on anything important that's out there.
　　Finally, whatever damage commercial fossil collectors sometimes do, if it weren't for them, many fossils would simply go undiscovered because there aren't that many fossil collecting operations that are run by universities and other scientific institutions. Isn't it better for science to at least have more fossils being found even if we don't have all the scientific data we'd like to have about their location and surroundings than it is to have many fossils go completely undiscovered?
　　Question:Summarize the points made in the lecture.being sure to explain how they cast doubt on specific points made in the reading passage.

作文：


The idea of the reading passage is presented that private collectors sell and buy fossils could slow down the development of both scientists and the gereral public. However, the Professor think such idea is a kind of eggagerate the issue,and he think the benefits of this new development outwigh its negative consequences.

The Professor do not think rarely chance for the public to see fossils can lead to a decline interest in fossils, he think commercial fossil hunting makes more fossils available for purchase, as a consequence, low-level public institutions could afford to interesting fossils and display them for the public,then, there will have greater exposure to fossils ,and can access fossils more easily.
The Professor rejects the claim in the reading that fossil trading business could make paleontologist miss out on potentially crucial discoveries about extinct life forms.She argues that it is the scientists that are the first and authoritive person to  evaluate the fossils. Before any important fossils trading, they must access the fossils ,so , the academic community does not miss any opportunity to study privately traded fossils at all.

Aditionally, the Professor challenge the final downsides of fossil of trading mentioned in the reading passage.The valuable scientific evidence associated with the fossils are also valuable to such private traders, after all, they want to discover more fossils and as a consequence, they would like to pay attention to  the information about their location and surroundings.
