解析:“如果电话上网就会和电脑一样”,与本文最后一句“电话不和网络连接”形成对比与呼应。
13.A.strike C.ask
B.visit D.attack
解析:攻击目标,这里和上文第9空形成呼应, 因此应用attack (攻击),而不用strike(打击);visit(参观)和ask(问)。
14.A.in C.on
B.by D.with
解析:“在”手机上的信息、电视画面等都用介词on。 15.A.send C.count
B.dial D.press

16.A.receive C.stop
B.ban D.prevent
解析:这种情况下急救中心的接线员就只好关闭系统以免受到干扰,因此用stop(停止)。receive表示“接到”;ban表示“禁止”;prevent表示“阻止”。

解析:直到这令人讨厌的病毒被清除掉,动词clear表示“清除”。而remove 表示“挪去”;clean表示“打扫干净”。

B.nor D.but
解析:本题用or表示“或者说,换句话说”。 19.A.stop C.kill
B.avoid D.find
