题目内容
10．Mary spends a lot of money on clothes her family is not rich．（ ）| A． | because | B． | though | C． | if | D． | so |
分析 虽然家庭并不富裕，但是玛丽却在衣服上花了很多钱．
解答 答案：B because意为"因为"引导原因状语从句；though意为"尽管"引导让步状语从句；if意为"如果"引导条件状语从句中；so意为"因此"引导结果状语从句．根据"her family is not rich"以及"spends a lot of money"可知尽管家庭不富裕，还是花了很多钱，所以要用though来引导让步状语从句，故选B．
点评 首先要掌握because，though，if，so这几个连词的意思以及引导从句，然后结合具体的题意做出正确选择．
