题目解答
答案
A
解析：这是一道句内动词辨析题，四个选项的解释分别为：[A]横扫，[B]跳，[C]走，[D]隐藏，原文中提出正是网络的匿名形成了网络上大量的犯罪行为，[B]、[C]不符合本文主题，[D]含义和作者表达网络犯罪猖獗的方向相反，故[A]为正确答案。
解析：这是一道句内动词辨析题，四个选项的解释分别为：[A]横扫，[B]跳，[C]走，[D]隐藏，原文中提出正是网络的匿名形成了网络上大量的犯罪行为，[B]、[C]不符合本文主题，[D]含义和作者表达网络犯罪猖獗的方向相反，故[A]为正确答案。
解析
本题考查动词辨析，需结合上下文语境判断最恰当的词义。关键点在于理解网络犯罪的猖獗程度，以及动词短语的固定搭配。
语境分析：
原文提到“网络匿名性导致网络犯罪激增”，空格处需填入描述犯罪扩散程度的动词。
- 选项A（swept）：意为“横扫”，常与“across”搭配，表示“席卷整个网络”，符合网络犯罪猖獗的语境。
- 选项B（skipped）：意为“跳跃”，与犯罪扩散无关。
- 选项C（walked）：意为“行走”，无法体现犯罪的广泛性。
- 选项D（ridden）：意为“骑、隐藏”，与语境矛盾（犯罪应是“猖獗”而非“隐藏”）。
结论：swept across 是固定搭配，强调犯罪行为的广泛影响，故选A。
