根据上面短文内容填空。

    Siri on iPhone 4S is like a person assistant. It lets you use your voice to do things on the iPhone. You

  can just talk to Siri as you talk to a person. Siri understands what you say, knows what you mean, and

 even talks back.

    Say something like "Tell my wife I'm running late." "Remind me to call the doctor. " "Any fast food

  restaurants around here?" Siri does what you say, finds the information you need, then answers you. It's

  like you're having a conversation with your assistant.

   Siri not only understands what you say,  but it's also smart enough to know what you mean. So when

 you ask, "Any fast food restaurants around here?" Siri will reply, "I found a number of restaurants near

 you." Then you can say, "Hmm. How about hambergers?" Siri remembers that you just asked about

 restaurants for something to eat, so it will look for KFC restaurants in the neighborhood. And Sift is

  active, so it will question you until it finds what you're looking for.

     When you want to do something, just ask Siri to help you do it. Siri uses almost all the built-in apps on

  iPhone 4S. It writes texts and sends email messages. It searches the web for anything you need to know.

  It plays the songs you want to hear. It gives you directions and shows you around. It makes calls, plans

  meetings, helps you remember and wakes you up. In fact, ask Siri what it can do-it even speaks for itself.

    Sift is easy to use and does so much. You'll keep finding more and more ways to use it.
