---Could I have some snacks between meals, mum?
---No, you __________.| A．couldn’t | B．shouldn’t | C．can’t | D．might not |
|
答案
| C |
解析
试题分析：can能，能够。Could是can的过去式，用于一般现在时态表示委婉的请求建议等语气。couldn"t 是can`t的过去式和虚拟式。在实际应用中，could`t是can`t的礼貌用法，含有不情愿的意思，加上有虚拟的含义，语气较弱。表示否定时can"t比couldn"t的否定意味更重。shouldn’t不应该； might not可能不。句意：我能在两餐之间吃一些小食品吗？妈妈。不，你不能。结合语境可知选C。
点评：情态动词的考查是初中英语考查的重点，平时学习中一定要熟记这些词的基本词义及用法上的不同，注意其用法及在句子中表达语气的不同。考试中结合语境选择合适答案。 |
