以下四道都是新东方蓝皮书上的. P138 36. If 6 gallons of gasoline are added to a tank that is already filled to 3/4 of its capacity, the tank is then filled to 9/10 of its capacity. How many gallons does the tank hold? 这题是理解的问题,按照答案,应该求的是容积,而我求的是现在装了多少.因为题目用了does，虽然是一般现在时，但前面也是用这个时态。如果问容积的话貌似用can更好啊，请问大家是怎么看出来求容积的？
P141 53. After paying a 10 percent tax on all income over $3,000, a person had a net income of $12,000. What was the income before taxes? 也是理解问题。根据答案，$3000部分是不用交税的，需要交的是扣除3000以后的部分，请问这是怎么看出来的？
P145 83. Which of the following integers does NOT have a divisor greater than 1 that is the square of an integer? A.75 B.42 C.32 D.25 E.12 这题我是猜对答案的，但是这题具体啥意思？求翻译题干。
P151 118. The figure above represents a system of roads along which traffic flows in the direction indicated by the arrows. If the traffic were to split evenly at each fork of the road system, what percent of the traffic entering fork C would exit at Y? 图没看懂，怀疑是不是错了，求高人解答，答案是87.5%
