C A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(监管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats. The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks. But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions. The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals. “Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects. In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(复制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals. When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones. 64.   What can we infer from the first paragraph? A.    FDA has waited for a long time to get this final report. B.    Products from cloned animals have been put into the market before. C.    People are having the products from cloned animals safely. D.    There have been once opposite opinions against cloned products. 65.   What does the underlined word “wary” mean? A. Disappointed.           B. Careful.         C. Fond.                                 D. Proud. 66.   It will be a few years before foods from clones come into the market, partly because _____. A.    people have little knowledge of the cloned animals B.    supporters can’t give powerful evidence to support that C.    the few cloned animals will first be used to create superior animals D.    they are a new generation for the customers and are too valuable for the customers 67.   What can we conclude from the passage? A.    FDA officials encourage people to eat more food from clones. B.    FDA officials think the food from clones will sell better than ordinary food. C.    People only worry about the health problems when it comes to foods from the clones. D.    All the foods will not have detailed labels on them.
