B: Sure.（客气请求的一般疑问句）3. many ,a lot of ,much 词语辨析many ,a lot of ,much ,这三个词都是表示“许多”。many是用来修饰可数名词, much用来修饰不可数名词，a lot of则用来修饰可数与不可数名词。例子：Peter has many friend .（可数名词的前面） Peter has much food for his birthday party. （不可数名词的前面）Peter has a lot of friend. （可数名词的前面）Peter has a lot of food for his birthday party. （不可数名词的前面）二、 不可数名词的归类1、表示液体：water, juice, milk, lemonade, coffee, coke, ink2、表示自然现象：snow, rain, ice3、表示食品类：rice, jam, honey, meat, bread, mutton, beef, tofu, eggplant, pork, chicken, fish,
