问题 According to the passage, the attempt to eradicate the AIDS virus ______.
Other scientists are looking at experiments that are similar in that they are ______.
选项 A、costly
B、economical.
C、traditional
D、bold.
答案D
解析 利用题干中的特征结构(修饰结构)“Other scientists ”和“similar”作为答案线索，这样发现答案相关句：And he emphasized that he is not urging widespread adoption of such early, aggressive treatment outside of trials．No one knows long-term risks. But other scientists are looking at similar experiments．But的出现表明But的前后句在句意上紧密相关，所以注意But的前句内容(划线句)，该句的意思是“没有人知道长期的风险”，该句内容暗示类似的实验是存在很大风险的，对比备选项判断只有 D(大胆地实验)最可能是答案，而且前面的句子中还出现了aggressive(把这种治疗方法称作“挑战性的治疗方案”)，综合这些分析，确认D是正确答案。
