Q: How can I filter junk mail on my iPhone?
问：我的iPhone手机如何过滤垃圾邮件？
A: The iPhone's email program doesn't include a junk-mail filter. It relies on your email service's junk-mail filtering system, such as the ones built into Gmail, Yahoo Mail or your company's email system, to clear out the spam before it gets to the phone. Obviously, these server-based filtering systems aren't perfect, so you'll still get some spam. But you might experiment to select the email service you feel does the best job. Once you decide, you can make that the main, or the only, service you use on your iPhone, and forward all the email from accounts that receive a lot of spam into an account on that relatively spam-free service.
答：iPhone的电子邮件程序不包括垃圾邮件过滤器。它依赖于你的电子邮件服务的垃圾邮件过滤系统，如Gmail、雅虎邮件或你所在公司的邮件系统在手机收到垃圾邮件之前清除它们。显然，这些基于服务器的过滤系统还不够完善，因此，你仍会收到一些垃圾邮件。但是，你可以试着选择你认为在这方面做的最好的电子邮件服务。一旦你决定了，你可以将它作为你的iPhone手机主要或唯一的服务，将所有收到很多垃圾邮件的账户中的电子邮件转到收到垃圾邮件相对较少的账户中。
Q: What model of laptop do you recommend for a student of middle-school age, at the $500 price range?
问：对一个中学生来说，500美元左右的笔记本电脑你推荐哪款？
A: At that price range, you have several broad choices, so it depends on how the student will be using the machine. If it will be mainly staying on a desk or just used around the house, you should be able to find a standard-sized laptop with a 14' or 15' or even larger screen, and adequate speed, memory and hard disk capacity, for around $500, or even less, depending on sale prices. If the student wants more mobility, then a high-end netbook, or a low-end 'thin and light' or 'ultrathin' machine would work, though their screens and hard disks might be smaller and their processors slower.
答：在这个价格范围内，你的选择余地较大，因此这取决于学生将如何使用这台电脑。如果主要放在桌子上或在家里使用，用500美元左右甚至更少的钱，应该能买一台标准大小的14口或15口甚至更大屏幕的笔记本电脑，并有足够的速度、内存和硬盘空间。如果学生希望有更强的移动性，那么高端的上网本，或是低端的“轻薄”或“超薄”电脑可能适合，不过这类电脑的屏幕和硬盘可能是更小，处理器也更慢。
However, if the student is a hard-core gamer, or does sophisticated video production, the graphics on any $500 laptop might prove inadequate, and you may have to spend more.
但是，如果这个学生是铁杆游戏迷，或要进行复杂的视频制作，那么任何500美元的笔记本电脑上的显卡可能都不够好，可能得多花点钱。
I have no particular model to recommend, since the best way to do this is to have the intended user try various models, to be sure she is comfortable with the screen and keyboard, and that the machine has whatever specific features she wants for the price.
我没有具体的型号推荐，因为买电脑最好的办法是让想购买的用户尝试各种型号，以确定他对屏幕和键盘满意，而且具体性能也符合他对这个价格下的电脑的要求。
