问题     Many students do not like to study history. They say that there are  (41)  many names and dates to   42    But if we do not know about the  (43)  , we can not understand the present well. For example, if we wish to know how men  (44)  to use fire, we have to know what men did  (45)  the past to travel at night or to keep themselves  (46)  in cold nights. Only a study of history will make us realize(意识到)  (47)  everything we do today is the result of what  (48)  people did in the past.
    As we  (49)  history, we learn many interesting  (50)  .History helps us understand our present life better.
选项 A、learn
B、learnt
C、was learning
答案B
解析 考查时态。人类学会用火是过去发生的事情，故要用过去时态。learn的过去式、过去分词有两种形式，即learned，learnecl或者leamt，leamt。注意，[C]项为过去进行时，但此处显然不含“进行”义。另外，由后面结构相同的we have to know what men did…一处所用时态也完全可推知本题答案。
