【解析】

試題分析: 本文是一個汽車旅館的老板把每周的入住情況時行了統(tǒng)計。

1.A 推斷題。根據(jù)文中提到To do this she uses a calendar and writes the number of units occupied in a small box in the right-hand square of each date她用日歷，寫上房間號在小盒子上，標(biāo)上日期，故可知把七月14日到20日之間的數(shù)量相加，故選A項。

2.C 推斷題。要想算周四的平均入住率，把周四的總數(shù)相加再取平均，故選C項。

3.C根據(jù)“Which has 50 units”，和題干的第一句話，可知第3題的做法為：50×90%=45,從表中選取大于或等于45的數(shù)目，可推出答案C。
