teenagers____their health because they play computer games too much.
A have damaged B are damaging C damaged D will damage
teenagers____their health because they play computer games too much.A have damaged B are damaging C damaged D will damage
B are damaging 这里强调的是持续的动作,而不是结果,因此用正在进行时
B are damaging
A
选择B，用现在进行时表示持续发生的动作，即太多的电脑游戏正在摧毁年轻人的健康。
排除其他选项是因为because引导的状语从句中，采用一般现在时，表示经常发生的动作，从句选择A、C、D的时态不对。
