How come? 为什么呢? 怎么会呢?How come? 是英语口语中的一个习语，相当于汉语“为什么;怎么会”等意思，既可独立使用，也可在其后接句子，用来询问事情的缘由或状况。用法分析：独立使用时，表示“为什么;怎么会”。例如：You are so late. How come? 你怎么这么晚？在句中使用时，表示“为什么;怎么会”。例如：How come you didn't tell me? 你为什么不告诉我？例句：How come you are not in class today? 你今天怎么不在班上？How come you didn't answer my call? 你为什么没有接我的电话？How come you failed the exam? 你为什么考试不及格？2. swing dance摇摆舞swing dance 是爵士舞的一种，初现于20世纪早期的美国，其曲调动听活泼、节奏鲜明。听到这种音乐，人们不禁会随着它的节奏和韵律摆动身体，故而得名。用法分析：作为名词，表示“摇摆舞”。例如：I love swing dancing. 我喜欢跳摇摆舞。作为动词，表示“跳摇摆舞”。例如：They were dancing swing in the dance hall. 他们在舞厅里跳着摇摆舞。例句：I love swing dancing. 我喜欢跳摇摆舞。He is a professional swing dancer. 他是一位专业的摇摆舞舞者。They were dancing swing in the dance hall. 他们在舞厅里跳着摇摆舞。3. The answers to our questions about watching television were also interesting. 对我们提出的有关看电视的问题的回答也颇有意思。用法分析：主句：The answers were also interesting. 主语是复数，所以谓语用were。表示“回答也颇有意思”。定语：to our questions about watching television 用介词to 表示“对...的问题”。表示“有关看电视的问题”。名词question后则往往搭配介词about，表示“关于/有关...的(问题)”。例句：There's no easy answer to this problem. 这个问题没有简单的答案。Her answer to your question is a big “NO”! 她对你所提问题的回答就是一个大大的“不"字!He asked us some questions about our daily habits. 他问了一些有关我们日常习惯的问题。Her questions about you were not so friendly. 她有关你的那些问题并不那么友善。4.
