不能 简单地用Yes或No 来回答。选择疑问句把选择的余地缩小在数目有限的事物、行动
等上面，可以有 无限性的选择、3项选择以及两项选择。选择疑问句通常可以采用缩略形
式，如：
Beef or lamb? 牛肉还是羔羊肉？
选择疑问句的例句如：
What would you like to drink? 你喜欢喝什么？（无限性选择）
WhichWhat would you prefer , tea or coffee? 茶和咖啡，你喜欢哪一种？（两项
选择）
Would you like tea, coffee, or milk? 你喜欢茶、咖啡、还是牛奶？（3项选择）
How shall we go, by bus or by train? 我们怎么走？乘公共汽车还是坐火车？
Did you go there, or didn't you? 你去了那儿还是没有去？
Did you or didn't you go there? 你是去了还是没有去那儿？
