大学英语：Americans generally pay the price

　3. Americans generally pay the price of a product without question， instead of trying to get a lower price by bargain.(介词后面需要有动词的ing形式来作介词的宾语)

　　4. Lower： 可以是adj.的比较级;也可以是v.表示降低

　　5. This may all be confusing to the visitor. (系动词后是现在分词作表语;之所以用ving是因为我们要考虑这件事情“令人迷惑”)

　　6. Read the advertisements so that you can compare prices.(so that 是因此的意思，表结果状语从句)

　　7. They don't offer the same services to buyers that department stores do.(定语从句中缺宾语可以用that)

　　8. Limit(v.限制)-limited(adj.受限的);expensive——inexpensive

　　9. Usually run by a small number of salespeople， these shops offer products that range from inexpensive to very expensive， depending on the shop.

　　10. One of the most interesting sections to visit is the frozen food section.(过分作定语)
