Passage One
Which of the following describes the proper use of one’s hands over dinner
A．One is never allowed to have both hands on dinner table.
B．One is allowed to use his recessive hand when he is cutting meat.
C．One must keep his dominant hand in his lap.
D．One must keep a knife in his recessive hand for cutting.
答案
参考答案：B
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。
