解答题
完形填空
I spent two months with an American family last year when I studied in America.
It is said, “The best house is in America, the best wife is in Japan, and the best food is in China.” So I took pride (自豪)and __21__ to __22__ “the best food” for my American family. Each day, regardless of my poor skill of cooking, I would do something in __23__ way: changing the dishes’ colour, the meat’s type or the soup’s style. (风味)Thus, my American friends could discover the __24__ of eating Chinese food. Because of my “__25__” job, I was often rewarded (奖励) by their __26__ of appreciation (感激)such as “very delicious”, “excellent”, etc.
But the joke was here: Yesterday, I cooked Sichuan style __27__ for dinner. I was __28__ at my achievement.(成就)
When all the family members arrived at the table, they first looked __29__ at the fish, then looked at me. “Why do all the fish have their __30__?” they asked, “It’s terrible!”
Terrible or beautiful? I don’t know. But I __31_ know that fish heads are delicious. The __32__ is the best part of fish; in __33__ only the respectable (受敬重的)guest can have the special honour of __34__ it.
Another __35__ thing is: The American friends often said to me “__36__” as they __37__ fruits or other things. According to Chinese tradition I would simply smile in answer to their kindness __38__ actually helping myself to any of the food. __39__, I said “help yourself” to them whenever I brought home fruits. Dear me, no matter how much or how often I brought home food, as long as it was nice to their taste, they __40__ hesitated (犹豫)to use their hands to “help themselves” until all was finished
