Private collectors have been lling 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 becau fossils that would otherwi be donated to muums where everyone can e them are sold to private collectors who do not allow the public to view their collections. Making it harder for the public to e fossils can lead to a decline in public interest in fossils, which would be a pity. More importantly, scientists are likely to lo 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 muums 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 u

For example, scientists have learned about the biology of nest-building dinosaurs called oviraptors by carefully obrving the exact position of oviraptor fossils in the ground and the prence 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.

中考作文满分 Professor:Of cour there are some negative conquences of lling 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 purcha, 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 lo 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 examin
ations and tests on the fossils themlves. So even if a fossil is destined to go to a private collector, it has to pass through the hands of scientific屏亮度
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 becau 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?史记共多少篇

The lecturer rejects the ideas prented in the reading passage about the problems involved with the booming business of commercial fossil trading. In her opinion, the benefits of this new development outweigh its negative conquences.
The lecturer does not agree with the first point made in the reading that private collectors will keep their fossil collection away from the public, leading the public to lo interests in fossils. She contends that the commercial trading of fossils actually makes them available to a wider public, beca
u everyone with a budget, such as private schools and libraries, can purcha them for study and exhibition.
The lecturer goes on to refute the claim in the reading that fossil trading business prevents scientists and public muums from benefiting from fossil finds, as the parties cannot compete with wealthy private buyers to acquire important fossils for rearch purpo. On the contrary, she argues, scientists themlves are the first to evaluate any important fossil before it can be sold in the commercial market at a price, so the academic community does not miss any opportunity to study privately traded fossils.思秋
Additionally, the lecturer challenges the final downside of fossil trading mentioned in the reading.The lecturer reminds us that the damages, if any, caud by private collectors in their field operations are more than offt by the effort they have made to increa the number of fossils available to the public that would otherwi remain undiscovered.
