| {{B}}One Good Reason to Let
Smallpox Live{{/B}} It's now a fair bet that we will never see the total extinction(灭绝)of the smallpox(天花)virus. When smallpox was completely got rid of in the world,scientists wanted to {{U}}(51) {{/U}}the killer virus in the last two labs -- one in the US and one in Russia. They asked:If smallpox has truly gone from the planet,{{U}} (52) {{/U}}point was there in keeping these reserves? In reality,of course,it was naive to{{U}} (53) {{/U}}that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have{{U}} (54) {{/U}} vials(小药瓶). And the last "official" stocks of live Virus bred mistrust of the US and Russia,{{U}} (55) {{/U}}no obvious gain. Now American researchers have{{U}} (56) {{/U}} an animal model of the human disease, opening the{{U}} (57) {{/U}}for tests on new treatments and vaccines(疫苗). So once again there's a good reason to{{U}} (58) {{/U}}the virus -- just in {{U}}(59) {{/U}}the disease puts in a reappearance. How do we {{U}}(60) {{/U}}with the mistrust of the US and Russia? {{U}}(61) {{/U}}. Keep the virus{{U}} (62) {{/U}}international support in a well-guarded UN laboratory that's open to all countries. The US will object,of course,just as it {{U}}(63) {{/U}}a multilateral(多边的)approach to just about everything. But it doesn't mean the idea is {{U}}(64) {{/U}}. If the virus is useful,then let's {{U}}(65) {{/U}}it the servant of all humanity -- not just a part of it. |
