问题 escape from(Para. 1) can be substituted for
Why is it difficult to detect neutrinos?

选项 A、Neutrinos can cross the entire universe.
B、Neutrinos can escape from different regions of space.
C、Neutrinos seldom interact with other particles.
D、Neutrinos are too rare in the space.

答案C

解析 本题问为什么中微子难于检测。文章第二段说明探测中微子是困难的,其首句"How can...matter?"就暗示了答案:正是因为中微子"interact so infrequently with other matter"才导致其难以被俘获。故"中微子极少与其他粒子相互作用"正确。中微子可以穿过整个宇宙;中微子可以逃逸不同的空间:此二项都是由"Neutrinos seldom interact with other particles"这一根本原因引起的,它们与"it is difficult to detect neutrinos"皆为结果,三者是并列的关系。中微子在宇宙中数量很少:原文"the neutrino interacts with other particles so rarely..."中rarely是副词,说中微子相互作用概率低,并不是说其数量少。
