    C

    How does WAP combine power and freedom.

    D

    How does WAP send out the latest traffic information.


    正确答案： A
    解析：
    文章的最后一句话“WAP combines power and freedom”是一个承上启下的句子。最后一段谈到较早一代的移动电话尽管方便，但能做的事情却有限；计算机使人们得以进入信息世界，但这个世界被关在一个丑陋的灰盒子里面。这个灰盒子被电缆固定在墙上；而WAP结合了“能量”与“自由”。所以下一段作者会论述WAP怎样结合了“能量”与“自由”。

    答案：D
    解析：
    考查强调句型。本题题干相当于I just wonder what makes him so excited.的意义，所以该题实际上为强调句型的特殊疑问句式。what 为宾语从句的连接词，且在从句中作主语。故本题选D。句意：我想知道什么使他如此兴奋。
