单选题The stability of the U.S.banking system is maintained by means of supervision and regulation, inspections, deposit insurance, and loans to troubled banks．For over 50 years, these precautions have prevented banking panics．Howeveg there have been some close calls．The collapse of Continental Illinois Bank&Trusted Company of Chicago in 1984 did not bring down the banking system, but it certainly rattled some windows． In the 1ate 1970s．Continental soared to a leadership position among Midwestern banks．Parts of its growth strategy were risky,however．It made many loans in the energy field, including$1 billion that it took over from Penn Square Bank of Oklahoma City．To obtain the funds it needed to make these loans, Continental relied heavily on short term borrowing from other banks and large 30-day certificates of deposit-"hot money", in banking jargon．At least one Continental officer saw danger signs and wrote a warning memo to her superiors, but the memo went unheeded． Although the Comptroller of the Currency inspected Continental on a regular basis, it failed to see how serious its problems were going to be． Penn Square Bank was closed by regulators in July 1982．When energy prices began to slip, most of the$1 billion in loans that Continental had taken over from the smaller banks tumed out to be bad．Other loans to troubled companies such Chrysler,International Harvester,and Braniff looked questionable．Seeing these problem, "hot money"owners began to pull their funds out of Continental． By the spring of 1984, a rnn on Continental had begun．In May,the bank had to borrow$3.5 billion from the Fed to replace overnight funds it had lost．But this was not enough．To try to stem the outflow of deposits from Continental, the FDIC agreed to guarantee not just the first$100,000 of each depositor's money but all of it．Nevertheless, the run continued． Federal regulators tried hard to find a sound bank that could take over Continental——a cornnlon way of rescuing failing banks．But Continental was just too big for anyone to buy．By July all hope of a private sector rescue was dashed．Regulators faced a stark choice：Let Continental collapse, or take it over themselves． Letting the bank fail seemed too risky．It was estimated that more than 100 other banks had placed enough funds in Continental to put them at risk if Continental failed．Thus, on a rainy Thursday at the end of July,the FDIC in effect nationalized Continental Illinois at a cost of$4.5 billion．This kept the bank's doors open and prevented a chain reaction．However,in all but a technical sense, Continental had become the biggest bank failure in U.S.history．

单选题For several years, scientists have been testing a substance called interferon(干扰素), a potential wonder drug that is proving to be effective in treating a variety of ailments, including virus infections, bacteria infections, and tumors. To date, the new drug has provoked no negative reaction of sufficient significance to discourage its use. But in spite of its success, last year only one gram was produced in the entire world. The reason for the scarcity lies in the structure of interferon. A species of specific protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so powerful that the amount given each patient per injection is very small. Unlike antibiotics, interferon does not attack germs directly. Instead, it makes unaffected cells resistant to infection, and prevents the multiplication of viruses within cells. As you might conclude, one of the most dramatic uses of interferon has been in the treatment of cancer. Dr. Hans Strander, research physician at Sweden's famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who has undergone surgical procedures for advanced cancer, half were given interferon. The survival rate over a three-year period was 70 percent among those who were treated with interferon as compared with only 10 to 30 percent among those who have received the conventional treatments. In the United States, a large-scale project supported by the American Cancer Society is now underway. If the experiment is successful, interferon could become one of the greatest medical discoveries of our time.
