Back in the early 1990s, we never would have suspected that population growth would have turned negative because of AIDS $\underline{ }$.
(mortal)
题目解答
答案
为了完成这个句子,我们需要选择一个合适的词来填空。句子的背景是20世纪90年代初,人们没有预料到艾滋病会导致人口增长变为负数。填空处需要一个与死亡率相关的词,因为艾滋病主要通过增加死亡率来影响人口增长。
选项是“mortal”,这个词的形容词形式是“致命的”或“死亡的”,但在这个句子中,我们需要一个名词形式。因此,我们应该使用“mortality”,意为“死亡率”。
完整的句子应该是:
Back in the early 1990s, we never would have suspected that population growth would have turned negative because of AIDS mortality.
解析:
1. **背景理解**:20世纪90年代初,艾滋病开始在全球范围内蔓延,导致大量人口死亡。
2. **句子结构**:句子的主干是“我们从未怀疑人口增长会变为负数”,原因是“艾滋病的死亡率”。
3. **词汇选择**:选择“mortality”(死亡率)而不是“mortal”(致命的),因为“mortality”更符合句子的语境和语法要求。
最终答案:
Back in the early 1990s, we never would have suspected that population growth would have turned negative because of AIDS mortality.
