解析：根据问题可知4个选项中有3项是从不同角度观看同一个骰子而得到的不同情形。本题的解题关键是观察B的位置，通过比较，B、C肯定不同，C、D肯定不同，B、D可能相同，从而可推断C项与其他三个图形不同。
4.At the eating contest the winner ate an average of 15 hot dogs at the first 20 sittings. After a further 20 sittings the average increased to 20 hot dogs. What was the average for the last 20 sittings?(C)

8.An aircraft flew from A to B at an average speed of 230 mph. It returned from B to A at an average speed of 300 mph. What was its average speed for the two journeys?
260 mph
解析：(设飞机从A到B耗时a小时，从B到A耗时b小时，那么可得出230a=300b；飞机飞行整个路程中所用的平均速度则为300b／(a+b)；将两个方程式合并，便可得出平均速度约为260．3 mph，四舍五人后取结果260mph。
