问题 Consumption of domestic fuel oil______from 150 gallons a month at the height of winter to practically nothing in July and August.

选项 A、differs
B、shifts
C、varies
D、switches

答案C

解析 此题的四个选项都有“变化;不同”的意思,但其含义和用法又有所不同。vary“变化,改变",它常用在vary from…to…的句式中,意为“由……到……情况不等”,如:The students inthis class vary in age from 18 to 21.这个班学生的年龄从18岁到21岁不等。可见此词最符合题意。differ(from)“不同;分歧”,如:Chinese differs greatly from English in pronunciation.汉语发音跟英语大不相同。shift“替换;转移”,如:shift the scenes“换布景”,shift a rifle from theright to the left shoulder“把枪从右肩转移到左肩”。switch“接通(on);关断(off);转换;改变(思路,话题等)”。
