1．选择疑问句。
含有or的问句称为选择疑问句。or之前的部分读升调，之后的部分读降调。这种疑问句不能简单地用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）
which/what 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？
2．一般现在时的单数第3人称形式（可参见 lessons 47～48语法部分。）

1．where do you come from? 你是哪国人？
问对方是什么地方人。come from表示**或籍贯。也可说：where are you from? 在第7课**现过类似的句子。
2．what's the climate like in your country? 你们国家的气候怎么样？
句中like是介词，不是动词，它的宾语是 what。又如：what's the weather like in spring?
climate指某一地区数年间的天气情况；weather是指某个特定的时间内晴、雨、风、雪变化。对于这类问题的回答可以是 it's very pleasant（很好）或 it rains sometimes（有时下雨）。这里的it均指天气。
3．it's often windy in march. 3月里常常刮风。
表示在某个月份里通常用介词in。类似用in的时间短语课文中还有 in april（在4月），in june（在 6月），in september（在 9月）等等。
often（经常），always（总是，老是），sometimes（有时）都是课文**现的表示非确定频度的副词。这些副词一般用来回答用how often 提问的问题。
语法 grammar in use
what…(be. look, etc.) like?
我们把what…like? 这一句型用于询问事物的状况，例如天气、气候等：
what's the weather like today? 今天天气怎么样？
what's it like today? 今天怎么样？
what's the climate like in your country? 你们国家气候怎么样？
或询问人物或事物的外观或特征：
what's your brother like? 你兄弟是个什么样子？
what's your house like? 你的房子是什么样的？
许多形容词可用以回答what…like? 这样的问题，并可根据上下文给以笼统的或确切的信息。例如课文中表示天气或气候的形容词有pleasant（宜人的），windy（有风的），hot（热的），cold（冷的），warm（温暖的）等等。
