要把简短回答说完整，先说出答案，再加上 because 和一个理由，最后补一个小细节或例子。“答案、理由、细节”这个模式能把 “Yes.” 变成对方可以接话的内容，几乎每种互动口语任务都会用到。
这是口语互动的第一课，后面的课都假设你已经会这样做。
为什么只答一个词会有问题？
互动是双方共同完成的工作。你只答一个词，对方就得一个人撑起整个对话。理由给了对方可以回应的内容，也展示了你能使用的语言。
你不需要讲很久，只需要让回答感觉完整。
怎样扩展回答？
- 先直接回答问题。 “Yes, I do.” 或 “I prefer the morning.”
- 用 because、since 或 as 加上理由。 “…because my head feels clearer.”
- 补一个细节或例子。 “For example, I finish my maths homework before school.”
- 停下来。 两三句就够了，让对方说话。
有用的连接词：because、so、for example、also、but、the only problem is。
例题详解
问题：“Do you prefer studying in the morning or at night?”
第一步，直接回答： “I prefer the morning.”
第二步，理由： “I prefer the morning because I feel less tired and I can focus more easily.”
第三步，细节： “For example, I can finish my maths homework in about forty minutes before school, but at night the same work takes me an hour.”
完整回答： “I prefer the morning because I feel less tired and I can focus more easily. For example, I can finish my maths homework in about forty minutes before school, but at night the same work takes me an hour.”
注意三点：答案放在最前面；理由和学习有关，而不是空泛的事实；细节很具体，所以可信。
要留意的错误
常见的失误是给出的理由只是把答案重复一遍。
错误回答： “I like football because it is good. It is very good.”
理由 “it is good” 没有提供新信息，第二句又重复了一次。
改正的方法是问自己“我踢球的时候发生了什么？”然后说出来。“I like football because I can see my friends every Saturday, and we always finish with drinks at the canteen.” 这样的理由只有你自己才说得出来。
自我检测
先大声用两三句话回答，再打开参考答案。
1. “Do you enjoy cooking?”
查看答案
一种可能的回答：“Yes, I do, because it helps me relax after school. Last week I made fried rice for my family and my brother asked for more.” 只要有直接回答、真实理由和一个细节，就是好回答。
2. “Would you like to live in a big city?”
查看答案
一种可能的回答：“I am not sure, because big cities have more opportunities, but they are also very crowded. For example, my cousin in Kuala Lumpur spends two hours in traffic every day.” 这表达了复杂的看法，同样是有效的回答。
3. 这个回答太短：“Yes, I have a phone.” 请用自己的话改进。
查看答案
一种可能的改进：“Yes, I have a phone, and I mostly use it to message my classmates about homework. I try to keep it away from my bed at night.” 改进后加入了手机的用途和一个习惯。
下一步
当扩展回答变得自然后，可以学习没听清问题时怎么办：恰当地请对方澄清。然后用口语互动练习题组检测自己。
有些学生在有准备时能把回答说完整，但遇到临场问题就缩回去。这正是老师可以在English as a Second Language 线上一对一补习中和你一起练习的地方。
