【正确答案】 B

【答案解析】[听力原文]21-25 In my childhood home, dinner was enjoyed with hushed voices, and the topics open for discussion were very much restricted. We were not allowed to bring up anything that was potentially unappetizing; body functions, bugs, murder and mayhem in general were all strictly forbidden topics. If I had to leave the table to use the toilet, I had to verbally excuse myself without mentioning what it was that I was going to do. "May I be excused, please? I need to wash my hands." I would say. My mother would say, "Sure." My father would often play a joke on us by saying, "Your hands don't look dirty to me!" As for eating, we did it quietly. No eating noises were allowed. Everything must be done as quietly as possible. Therefore, we had to eat with our mouths closed. To make a "smacking" noise was, perhaps, the worst offense possible. While drinking soup or coffee or wine "slurping" was also forbidden. If any sound whatever was created by our intake of food or beverage, it constituted bad manners! With that in mind, it was, of course, unthinkable to speak with one's mouth full of food, so speaking only occurred before or after one had taken in food and swallowed it. How one sits at the table is also prescribed. One is to sit up straight with the recessive hand in one's lap holding a napkin while the dominant hand holds the fork or spoon. The only time one is allowed to have both hands on the table is when one is using a knife to cut something, but as soon as the cutting is done, the recessive hand goes back to the lap. Also, elbows are not allowed on the table. Therefore, one props the arm against the edge of the table just below the elbow. One should never reach for any food on the table; one should ask someone sitting near it to give it to you. "Would you please pass the potatoes? .... May I trouble you for the salt?" These are phrases that you are likely to hear on any given night of the week at a family dinner. [分析] 推理判断题。 根据原文We were not allowed to bring up anything that was potentially unappetizing；body functions，bugs，murder and mayhem in general were all strictly forbidden topics可知讲话者在吃饭时不能谈各种可能会影响食欲的话题，如身体功能、虫子、谋杀或?昆乱等都是被禁止在餐桌上讨论的话题。由此可推断B项“一儿童被继父虐待至死”属于谋杀类，该话题不能在餐桌上讨论，因此B项为正确答案。 [解题关键] 掌握关于列举的信息。

【正确答案】 C

【答案解析】[分析] 事实细节的找寻和判断。 根据原文it was，of course，unthinkable to speak with one's mouth full of food，so speaking only occurred before or after one had taken in food and swallowed it可知嘴里装满食物时说话是难以想象的，因此只有在吃东西之前或将食物咽下去之后才能说话。由此可见C项内容与文中所举的好举止相符，该项为正确答案。 [解题关键] 掌握关于举例的信息。文中举例说明什么是好举止，将其与选项一一对照，便得到正确答案。

【正确答案】 C

【答案解析】[分析] 事实细节的找寻和判断。 根据原文One is to sit up straight可判断C项说法与原文相符，该项为正确答案。 [解题关键] 同义词替换。文中sit up straight与C项中upright意思相同。

【正确答案】 B

【答案解析】[分析] 事实细节的找寻和判断。 关于进餐时手的摆放，文中说一只手放在腿上扶餐巾，另一只手拿叉或勺子。两只手都在餐桌上的情况只有是when one is using a knife to cut something，but as soon as the cutting is done，the recessive hand goes back to the lap即一只手用刀切东西的时候，一旦切完，放在大腿上的手还要再放回去。由此可见B项与原文相符，该项是正确的。 [解题关键] 掌握对复合句结构有助于正确解题。本题原文中when引导的表语从句是主要信息处。

【正确答案】 A

【答案解析】[分析] 事实细节的找寻和判断。 根据原文One should never reach for any food on the table；one should ask someone sitting near it to give it to you可知永远不能去够桌子上的食品，如果想吃，就请邻座的人帮忙递给你，A项内容与原文相符，因此该项是正确答案。 [解题关键] 掌握有关建议的表达法。文中使用should表示正确做法，正是本题要点所在。
