问题补充：
My friend John has got a restaurant in a big city. It is near a supermarket. He gets ten robots for the restaurant. Each robot costs (价钱为) 20,000 yuan. The restaurant is not big, but very popular. Now more and more people come here for dinner.
The robots have different jobs in the restaurant. Two robots cook different kinds of food; one washes the dishes; one cleans the floor and the others give food to the guests (客人).
Although robots do most of the jobs in the restaurant, John is still very busy. He must do many things to keep the robots working well. Luckily, John is good at studying robots and he knows robots very well. I think in the future, there will be a lot of robot themed restaurants (机器人主题餐厅) around the world.

解析：这篇短文主要介绍了我的朋友John购买了十个机器人在餐馆工作。两个机器人做饭，一个刷碗一个擦地，其余的给客人端食物。餐馆虽然不大，但是很受欢迎。
【小题1】推理判断题。根据短文第二段Two robots cook different kinds of food; one washes the dishes; one cleans the floor and the others give food to the guests (客人).描述两个机器人做饭，一个刷碗一个擦地，其余的给客人端食物，可知10-1-1-2=6，故选D。
【小题2】细节理解题。根据第三段Luckily, John is good at studying robots描述可知John擅长研究机器人。故选B。
【小题3】推理判断题。根据第一段Each robot costs (价钱为) 20,000 yuan.一个机器人20，000.那么十个共200，000yuan.故选C。
【小题4】是非判断题。根据第一段The restaurant is not big, but very popular描述可知餐馆虽小但是非常受欢迎。故选D。
