【简答题】
①It’s “laughably absurd” on one blog and a “magical revolution” on another.Bloggers are talking about the same device—the Apple iPad, which hit store shelves last week. ②Tech-heads hate the iPad because it has many functions—you can e-mail, browse the Web, read books—but it has no specialty.There are other devices on the market that do all its functions faster, cheaper and more efficiently.Get a Blackberry to scan e-mails or any old laptop to access the Internet. ③This first version of the iPad lacks many basic features.Tech-heads dislike the device not because of what it offers, but because of what it doesn’t offer.It doesn’t have Flash, and it doesn’t have a camera.It can’t access many of the world’s mobile applications, and it has a very restricted apple store.Based on purely technological grounds, the iPad is said to lack more than it gives. ④But if you are not a crazy tech-head, and you love the iPod and iPhone, “this device is for you,” said Steve Jobs, Apple’s CEO.The iPad will take online activities truly mobile.It will allow you to read the news in bed, check a recipe in a busy kitchen or view a large-scale Google map. ⑤Perhaps most important to the masses, it is a traditional computer without trouble.There are wireless, but it’s totally mobile.You press a button and it comes on in seconds.To add a program, you just download it from the Internet.Since almost everyone uses a computer in the office or at school, the need for the traditional desktop model at home is disappearing.Slate Magazine’s Farhad Manjoo calls the iPad the perfect alternative to the home computer system. ⑥But no matter how you feel about the iPad, as a tech-head or an everyman, there’s no arguing with its appeal.Love it or hate it, the iPad sold over 600,000 units on its opening weekend, surpassing the iPhone’s record sales in 2007. 1.What can be the best title for the text? A.Loving and hating the iPad      B.An exciting invention C.A home computer substitute       D.The iPad—a wise choice 2.According to the text, which of the following is Not true of the iPad?
