In the past，they had to use the stars in the sky as 4       to tell them where they were. However，this melhod didn't work very well when the weather was bad. So the GPS is like a 5       "star".it is a great invention that can

The iPhone 4S is a touchscreen-based smart phone developed by Apple Inc. It is the fifth generation(代)of the iPhone. It was announced on October 4,2011.

Siri on the iPhone 4S is like a person assistant. It lets you use your voice to do things over 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. 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, ^u Any fast food restaurants around here?" Siri will reply, "I found a number of restaurants.”Then you can say， "How about French fries?" Siri remembers that you have just asked about restaurants for something to eat，so it will look for KFC restaurants in the neighborhood. And Siri is active. It will question you until it finds what you're looking for.

When you want to do something, just ask Siri to help you. Siri uses almost all the built-in apps on the iPhone 4S. Ft writes texts and sends email messages. It searches the web for anything you need to know. It plays the songs you want to hear. Tt gives you directions and shows you around. It makes calls, plans meetings, helps you remembet" and wakes you up. In fact,ask Siri what it can do ― it even speaks for itself.

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