How can a single postage stamp be worth $16 800？ Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony Mauritius , a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer – Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius ’ Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy

For a few excited days last week, however, it seemed as if the whole world was a cancer patient and that all humankind had been granted a reprieve(痛苦减轻) . Triggered by a front-page medical news story in the usually reserved New York Times, all anybody was talking about--- on the radio, on television, on the Internet, in phone calls to friends and relatives----was the report that a combination of two new drugs could , as the Times put it, “cure cancer in two years.” In a matter of hours patients had jammed their doctors’ phone lines begging for a chance to test the miracle cancer cure. Cancer scientists raced to the phones to make sure everyone knew about their research too, generating a new round of headlines. The time certainly seemed ripe for a breakthrough in cancer. Only last month scientists at the National Cancer Institute announced that they were halting a clinical trial of a drug called tamoxifen (他莫昔芬) ------ and offering it to patients getting the placebo(安慰剂) -----because it had proved so effective at preventing breast cancer (although it also seemed to increase the risk of uterine(子宫的) cancer). Two weeks later came the New York Times’ report that two new drugs could shrink tumors of every variety without any side effects whatsoever. It all seemed too good to be true, and of course it was. There are no miracle cancer drugs, at least not yet. At this stage all the drug manufactures can offer is some very interesting molecules, and the only cancers they have cured so far have been in mice. By the middle of last week, even the TV talk-show hosts who talked most about the news had learned what every scientist already knew : that curing a disease in lab animals is not the same as doing it in humans. “The history of cancer research has been a history of curing cancer in the mouse,” Dr. Richard Klausner, head of the National Cancer Institute, told the Los Angeles Times. “We have cured mice of cancer for decades---and it simply didn’t work in people.” 第11题：According to the passage, a person suffering from cancer will A．give up any hope.
