iPhone Duo 起价1999美元，10月23日开卖

Apple's new phone isn't on sale yet, and the price has already made many people stop and look.

A phone costs one thousand nine hundred ninety-nine dollars.

It's called iPhone Duo, and it's Apple's first foldable phone, officially announced on September 9th.

Apple never had a phone like this before, so as soon as the name came out, many people wanted to know how it works.

When you close it, you see the outer screen, and you can use it like a normal phone to check messages.

When you open it, you see the larger inner screen, and you can use it to watch movies or read things.

The outer screen is 5.4 inches, and the inner one is 7.6 inches.

Inches are a common unit for measuring screen size.

You don't need to remember two numbers, just remember that closed it's smaller, and open it's bigger.

One phone can be used in two ways, and that's the easiest part of this launch to understand.

But after seeing the large screen, many people immediately ask another question: when can I buy it?

Apple gave two different dates.

Pre-orders start on October 16th, and you can tell Apple first, "I want to buy it."

Official sales start on October 23rd, and only then will the phone appear in stores.

So hearing "Apple announced it" now doesn't mean you can get the phone today.

Apple says this phone will be sold in more than seventy countries and regions, and China is among them.

For people living in these places, the iPhone Duo will arrive in stores soon, and the price is the hard part.

One thousand nine hundred ninety-nine dollars is the starting price, and not everyone wants to spend that much on a phone.

Some people read very long articles on a small screen every day and want more space after opening it.

People like that may find it useful to put a large screen into a phone that can close.

Others say today's phones are already good enough, so why spend so much more?

Both ways of thinking are easy to understand.

This news is different from Apple's previous foldable phone rumors.

Before September 9th, people could only guess what it would be called and how much it would sell for.

Now the name, the sizes of the two screens, the starting price, and the sales dates are all announced by Apple itself.

Apple says it's called iPhone Duo.

The outer one is 5.4 inches, and the inner one is 7.6 inches.

The starting price is one thousand nine hundred ninety-nine dollars.

Pre-orders start on October 16th, and sales start on October 23rd.

If you walk into a store and see this phone, will you open the screen first, or look at the price first?
