回答：这里aren't saying表达了什么态度？跟一般现在时有何区别？为什么不用一般过去时呢？
 这里aren't saying 现在进行时，表示说话人说话时正在进行的动作，并不表明这一动作什么时候开始，什么时候结束。强调现在，说话人说话时 （虽然）一直还没有说（Google收购花了多少钱的事），不知道以后会不会说（这个事）。表达了他们虽然迟迟不说这个事，但急于说了另一件事， 是不是他们要隐瞒什么。
跟一般现在时有何区别：一般现在时表示包括“现在”在内的一段时间内经常发生的动作或存在的状态；现在进行时强调现在正在进行的动作。句子中强调现在没说这个动作。
但不能用一般过去时，因没说这个动作一直到现在说话人说话时还在进行。
