问题     Still want a laptop? That is so yesterday. Get ready for the next stage in the personal computer revolution: It’s the ultra-thin, dirt-cheap netbook.
    According to a New York Times report last week, personal computers are about to go through their biggest change since the rise of the laptop. By the end of the year, consumers are likely to see laptops the size of thin paperback books that can run all day on a single charge and are equipped with touch screens or slide-out keyboards.
    The netbook is a kind of portable computer with leaner functions for online surfing and basic computing activities, for example, word processing. To cut the cost and weight, they usually have a low-powered processor, small screen, narrow key board, and no optical disk drive.
    At present, some of these devices feel more like a toy than a full-feature computer. That’s because most of the netbooks sold today run on an Intel chip called Atom. This is a lower-power version of the company’s standard laptop chip. So they have trouble running demanding software like games and photo-editing programs. But this year, a group of companies who make cheap, power-saving chips used in cell phones are applying that expertise to PCs. That means they will break Atom’s netbook dominance and reduce the size while letting it run more complicated programs.
    The big winner in the rise of netbooks will be the consumers. AT&T announced last week that customers in Atlanta, Georgia, US, could get netbook for just $ 50 if they signed up for an Internet service plan. This trend will soon spread to Asia, according to industry experts.
According to the passage, the new generation of laptops______.
选项 A、is just as good as the ones used before
B、can not be used for a long time
C、is greatly advanced technically
D、is cheap and dirty
答案C
解析 推理判断题。根据第二段中的“到年底，人们就能用上像简装书一样大小的笔记本电脑了，这样的电脑不仅配有触摸屏和滑动键盘，而且只需充一次电即可运行一整天”可知，这种新一代的掌上电脑在技术上非常先进。
