选项 A、constrain
B、confine
C、restrict
D、limit
答案 D
解析 [B]、[C]、[D]的一般含义为“限制”或“局限”。[D]limit指时、空、程度、量等方面的“限定”，其内涵是如果超出了这种限度就会受罚或遭到令人不快的后果；此外，这个词也常用来表示“局限”。[C]restrict区别于limit的地方在于：restrict“限制”的是范围，而limit侧重于表示“限制”到某个点。[B]confine强调的是“约束”或“束缚”，而[A]constrain表示限制时，跟confine的意思一样，但不同的是还可以有“强迫”的意思。根据上述分析，答案为[D]，本句的意思为“…在网上去限制那些有密码的人进入某些网页还是有可能的”。
