阅读下面短文，掌握其大意，然后从各题所给的A、B、C和D项中，选出最佳选项。

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   21   more than he has to. So how come he was inviting us round for a meal? Had he bought something   22   for 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?

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.

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.
