house is in the U.S.A., the best wife is in Japan, and the best food is in China.
      "So I took __1__ and pleasure to __2__ "the best food" for my American family. Each day,
regardless of my poor skill of cooking,I performed(表演)my play in __3__ way:changing the dishes'
colour,the meat's type or the soup's style(风味)．Thus,my American friends could discover the __4__ of eating Chinese food． Because of my"__5__" job,I was often rewarded(奖励)by their __6__ of  
appreciation (感激)  such  as  "very  tasty","excellent", etc. 
     But the joke was here: yesterday, I cooked Sichuan－style __7__ for dinner. I was __8__ at my
achievement(成就)． 
     When all the family members arrived at the table,they first looked __9__ at the fish,then looked at
me. "Why do all the fish have their __10__?" they asked,"It's horrible!"
     Horrible or beautiful? I don't know. But I __11__ know that fish heads are delicious. The __12__is the best part of fish; in __13__ only the respectable(受敬重的)guest can have the special __14__of
enjoying it.
     Another __15__thing is:the American friends often said to me" __16__ "as they __17__ fruits or
other things.
      According to Chinese tradition(传统),I would simply smile in answer to their kindness __18__
actually helping myself to any of the food. __19__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 __20__ hesitated(犹豫) to use their hands to "help themselves" until all was finished.
