It’s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it — one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?

选项 A、looked for
B、sought
C、found
D、talked about
答案C
解析 opening the way for tests on new treatments and vaccines：“为试验新的治疗方法和新的疫苗开辟了道路”。这是句子的下半部分。可以看出，上半部分所描写的model应该是实际上存在的。此处应该用found。它是外延动词，表示model是存在的。looked for和 sought是内涵动词。它们引起的名词短语并不一定有外延。因此是不合适的。talked about是“谈论”的意思。用在这里，也是不妥的。
