----________ have you been studying at school? ----For more than four years． A．How often B．How long C．How old D．How far

Answer 1

B

试题分析：How often多久一次；How long多长；How old多大；How far多远。根据下文，大约超过四年。可知上文问的是时间长短，故选B。 点评：该题型是属于英语考试中的基础题型，是必考内容。答题前首先要理解每个选项的基本含义及用法，并注意交叉含义间的区别，然后根据答语，以及该疑问词在句子中承担的句子成分选择正确答案。
