问题     现在，很多孩子都用上了手机或经常上网。一个古老的现象——恐吓，也插上了高科技的翅膀。孩子在教室或操场上受到威胁，至少可以从老师或家长那里得到某种庇护。调查发现，有超过1／4的年轻人遭受过来白手机或电脑的威胁。其中，10％的人在手机上接收过恐吓或威胁性的信息，7％的人在网上聊天室受到过骚扰，还有4％的人收到通过电子信箱发来的恐吓信。 [br]  
选项
答案     China is cooperating with an American company in developing VGA and ultrahigh resolution displays for video phones. This microdisplay is basically liquid crystal material sandwiched between a layer of glass and a computer chip. On this computer chip you have an array of tiny little pixels, or picture elements, that the computer can turn on and off to affect the liquid crystal materials. And when all those picture elements are turned on and off, in a giant array, you can have a full high-resolution picture comparable to your computer monitor. This phone has been modified to include a microdisplay and a camera. The idea is, while talking on the phone you can send images on the display screens to the person you’re talking to over the line. They can retrieve the images from their own camera phone, a fax machine or email.
