Since my review of the new Apple iPad tablet last week, I have been bombarded with questions. This is natural. The iPad is a real computer that overlaps many functions of a laptop, but works very differently from one.

自上周我写了对苹果公司(Apple)新推出的iPad平板电脑的测评以来，读者的提问就像雪片一样飞来。这很正常。iPad是一款真正的电脑，与笔记本电脑有很多功能是相同的，不过工作方式却大不一样。

So here are answers to some of the most common questions I've received, in hopes they may help clear up any confusion. One caveat: Apple is offering a 'sneak preview' on Thursday of a forthcomingrevision to the iPhone operating system, which powers the iPad, so some changes might be revealed.

本文中，我对所收到的一些最常见问题进行了解答，希望可以帮大家解惑。值得一提的是：苹果公司将在美东时间周四提供即将上市的、修改后的iPhone操作系统供大家"秘密预览"，iPad用的就是这个操作系统，所以届时可能会出现一些变化。

Can you print from an iPad? Apple didn't build in a printing function, so you can't just tap a menu button to print an email, photo or Web page. But a few third-party apps allow printing of some items from an iPad to a networked printer. One is Print Online. It costs $5 and I tested it successfully. But these apps are complicated and limited workarounds -- inadequate substitutes for built-in printing.

iPad能打印吗？苹果没有内置打印功能，所以你无法仅仅通过按下一个菜单按钮就打印电子邮件、照片或网页。不过，有一些第三方应用程序让你可以在联网的打印机上打印出iPad上的一些内容。Print Online就是这样一个应用程序。它售价五美元，我对它的测试很成功。不过，这些应用程序只是复杂而有局限性的办法，不能完全代替内置打印机。

The iPad lacks a USB port, so how do you get files into it? Like the iPhone and iPod Touch, the iPad has the familiar Apple connector port and comes with a cable that links this port to a USB port on a PC or Mac. Then, using iTunes on the PC or Mac, you can sync over to the device your songs, photos, videos, contacts, apps and more.

iPad没有USB端口，那么你如何把文件传输到iPad中？和iPhone和iPod Touch一样，iPad有着人们熟悉的苹果连接端口，而且有一条数据线可以把这个端口与个人电脑或Mac苹果电脑上的USB端口相连。这样，在个人电脑或Mac上使用iTunes，你就可以把歌曲、照片、视频、联络人、应用程序等同步到iPad上。

New to the latest version of iTunes is a function that will also transfer to the iPad files like Microsoft Office documents. But this feature only works if you've installed on your iPad certain programs that can edit these documents, such as Apple's optional $10 word-processor, spreadsheet and presentationprograms. Documents can be moved in the other direction, too.

iTunes最新版本上新增加的一个功能是，它还能把Microsoft Office文件等传输到iPad。不过，只有当你在iPad上安装了能够编辑这类文件的特定程序后，这个功能才可以使用，这类程序包括可以选择购买的苹果10美元文字处理、表格和演示程序。文件也可以反向传输。

You also can get some types of documents into the iPad wirelessly, if you receive them as email attachments or as downloads from the Web. For example, if you receive a Word-document attachment, and you have Apple's Pages word processor installed, you can send it to Pages, where it can be stored and edited. Pages can then send back the edited version.

你还可以将某些类型的文件无线传输到iPad上，如果这些文件是电子邮件附件或从网上下载的。举例来讲，如果你收到了一份Word文档附件，而且你已经安装了苹果Pages文字处理器，你就可以把文件传送给Pages，进而进行存储和编辑。Pages然后可以把编辑好的版本传回来。

Is there a way to type on the iPad without laying it flat and using the virtual keyboard? There are several. Apple sells a $39 case that bends to angle the device in a more convenient typing position (and allows for hands-free video watching). The company also sells a $69 accessoryphysical keyboard that features a dock at the rear to hold the iPad upright. In addition, you can type on the iPad using Apple's $69 wireless keyboard for the Mac, which can be held on your lap.

有什么方法可以不必把iPad放平后使用虚拟键盘来打字的吗？方法有几种。苹果出售39美元的Case外盒，可以把iPad摆放到一个更方便打字的角度（还可以不用手拿着而观看视频）。苹果还出售价格69美元的物理键盘配件，它后面有一个托，可以把iPad立起来。此外，你可以用苹果69美元的无线Mac键盘在iPad上打字，键盘可以放在你的膝盖上。

Can I run Windows or Mac programs on the iPad? Not unless their makers produce iPad versions of these programs. The iPad doesn't run the Macintosh or Windows operating systems, so it can't run programs designed for them. It runs the iPhone operating system, which is only compatible with iPhone and iPad apps, of which there are more than 150,000. There are some iPad and iPhone apps that let you remotely control Windows and Mac computers, so you could indirectly run Windows and Mac programs via the screen of an iPad, but that isn't like running the programs locally.

我能在iPad上运行Windows或Mac程序吗？只有程序开发商生产出了用于iPad的程序版本才行。iPad运行的不是Mac或 Windows操作系统，所以无法运行为这两种操作系统设计的程序。iPad运行的是iPhone操作系统，只能与iPhone和iPad应用程序兼容，而这类程序有15万个以上。不过，有些iPad和iPhone应用程序让你可以遥控Windows和Mac电脑，这样你就能通过iPad的屏幕间接运行 Windows和Mac程序了，不过这和本地运行程序是不一样的。

I hear the iPad lacks multitasking. What are the downsides of this? First, let me clarify that the iPad (and iPhone) can technically perform multitasking, or running more than one program at once. But Apple has chosen to limit this ability to some of its own built-in apps, and deny it to third-party apps. For instance, the built-in email program will continue to receive messages while you are watching a movie on the built-in video player.

我听说iPad不支持多任务处理。这带来的不便是什么？首先，我要澄清一点，iPad（和iPhone）理论上讲可以进行多任务处理，即同时运行一个以上的程序。不过苹果选择将这种能力限制在一些苹果公司自己的内置应用程序上，而不适用于第三方应用程序。举例来讲，当你用内置视频播放器看电影时，内置电子邮件程序可以让你继续接收邮件。

The downsides of denying multitasking to all apps are considerable. For example, you can't listen to streaming music from the Pandora music app while checking email. And you can't view fresh Twitter posts while on other apps. You have to close the app you're in, then re-launch a Twitter app and wait for it to fetch the new posts. And, you can't, say, check email or surf the Web while waiting for a complex game to load in the background, because the game stops once you change to another app.

多任务处理并非适用于全部应用程序，这带来的不便是相当大的。举例来讲，你在查阅电子邮件的时候，无法同时从Pandora音乐应用程序收听流媒体音乐。你在运行其他应用程序的时候，无法查看Twitter新贴。你必须先退出正在运行的应用程序，然后再打开一个Twitter应用程序，等待它刷新载入新贴。再比如，当你等待一个复杂的游戏在后台加载的时候，你不能查阅电子邮件或上网，原因是一旦你转到另一个程序，游戏就停止了。

Since the iPad's battery is sealed in, how do I replace it? The battery isn't designed to be replaceable by the user. Apple will replace your iPad with one containing a fresh battery for $107, including shipping. The process takes up to a week. Most important, you will lose all your personal data unless you back it up regularly to your computer and restore it on the replacement iPad. Details are at: apple.com/support/ipad/service/battery/.

iPad的电池是内置的，我怎么才能更换电池？电池的设计初衷并不是让用户自行更换的。花107美元（包括运费），苹果会给你更换一部带有新电池的iPad。这个过程最长要用一周时间。最重要的是，除非你定期把iPad上的文件备份到电脑上，然后再重新装到新的iPad上，否则你会失去全部的个人数据。你可以登录apple.com/support/ipad/service/battery/.查看更多信息。
