在美国的大多数大城市，游客几乎可以找到各种类型的餐馆。电话薄根据餐馆名字、所在城市位置或食物种类，列出每个城市的餐馆。大城市的餐馆价格差别很大。许多餐馆在橱窗里张贴菜单，让你进去之前就能对食物的价格和种类有所了解。假如没有，而你又不知道那家餐馆的饭菜价格，那么进去之后，先要一份菜单，再入座，要不就直接问价格范围。光看餐馆的外表，可能会产生错误的判断——外表普通的小餐馆，也许实际上极贵，而外表看来昂贵的大餐馆，价钱可能很公道。
特殊句式分解：Many restaurants post their menus in the window so you can have some idea of the price and kind of food before you enter. 本句中有时间状语从句，从before到句末为从句部分。
If the menu is not posted, and you are uncertain about how expensive the place is, ask to see a menu before you are seated at a table, or else just ask about the price range. 本句中有条件状语从句和时间状语从句，从if到posted的部分为从句部分，从before到句末是从句。
Appearances from the outside can be misleading —— what looks like a small, informal restaurant may really be very expensive, and what looks like a large, expensive restaurant may be very reasonable.本句中有宾语从句，从what到restaurant的部分为从句的部分。
考点：list：列出；menu：菜单；be seated：就座；price range：价格范围；misleading：误解
