Recently I was invited to a friend’s house for supper—and had a meal I have never had before.
All the friends invited were a little surprised. It’s not that Ben is unsociable, or a bad cook, but it’s just that he never 21more than he has to. So how come he was inviting us round for a meal? Had he bought something 22for his friends? He greeted us at the door and showed us into his dining room where a 23_ -table was waiting for us.“Nothing but the best for my friends!”said Ben. We all sat down and looked 24 at each other—what was he up to?
Ben returned with four bowls of hot soup.“It’s a mixture of carrots, potatoes and tomatoes,”said Ben. The next 25was also a little strange in that we didn’t quite know what it was again. It’s just another mixture of vegetable.
As we ate we chatted and finally the 26 turned back to what we were eating.“Was there a recipe(食谱) for this,”asked Marina,“or did you 27 it up?”Ben put his fork down.“What I cooked depended on what I could find.”Marina was surprised.“But you can find anything in supermarkets these days.”“But there’s 28 choice in what you can find outside supermarkets,”he replied.
Seeing that we had all finished the food, Ben decided to tell the truth. He had read recently that supermarkets usually throw away 5 percent of their food every day. So Ben decided to look inside his local supermarket bins. There he found food that was slightly out of 29, boxes of throw-away vegetables and fruit.
So Ben had successfully provided a decent(体面的) meal for his friends, and made us aware of the fact that there are many poor people who need the food, but the amount of food thrown away is enough to 30 millions of people.

解析：21. 答案为B。 结合上下文可以推出Ben一般情况下是不请朋友吃饭的。
22. 答案为B。作者不明白为什么这次Ben会有这样的举动，因此猜测可能是什么特别的东西。
23. 答案为D。桌子已经摆放好，表示Ben已经为此作了一些准备，符合招待客人的语言情景。
24. 答案为A。由于Ben把这件事搞得很神秘，从而给他们带来紧张感。
25. 答案为A。course在此表示一道菜。
26. 答案为D。从聊天再把话题转移到当时所吃的食物上来，非常符合语言情景。
