| We Want the Best! We did a survey of things that interest young people today. This is what they told us. Most of the cafes in town are good, but The Turk’s Delight, the newest cafe to open here, is the most popular. It is also the most expensive, but the coffee is the best and the chairs are the most comfortable. What’s more, the music they play in the cafe is the best. The cell phone that everyone wants to buy is the V-Phone. This is the coolest phone around because it is like a computer. It has the most extras. You can take photos, make videos, check your e-mail, and of course, make phone calls. And what video game is the best today? Well, everyone agrees it is Viper Boy. It has the best graphics (图画), the most realistic (栩栩如生的) sound and the most interesting story. | ||||||||||||
