【导语】本文主要讲解了未来学生的普通的书包将会被轻轻的电子书包所代替，并且阐述了电子书包的一些特征。
1．句意：据说，电子书包将很快在中国的中学中投入使用。
use用处；useful有用的；used二手的。介词into后接名词use。故选A。
2．句意：沉重的书包长期以来一直是一个严重的问题，但电子书包将解决这个问题。
idea想法；problem问题（坏问题）；question问题（一般性的问题）。根据“Heavy schoolbags have been a serious”可知，这是一个严重的问题。故选B。
3．句意：沉重的书包长期以来一直是一个严重的问题，但电子书包将解决这个问题。
work it out解决它；work out it错误搭配，it放在中间；work out解决。此空指解决这个问题，用it代替problem，work out是动副短语，代词放在中间。故选A。
4．句意：一个书包比一般的书包轻得多。
very很； much太；too much太多。此空修饰比较急lighter，应填much。故选B。
5．句意：也许电子书包应该被称为电子教科书。
call动词原形；calls动词三单；called动词过去式或过去分词。根据“should be”可知，此空应填过去分词与其构成含有情态动词的被动语态。故选C。
6．句意：它和普通的书一样小，但它仍然可以有所有的学习的东西，如课本，练习本等。
small小的，形容词原级；smaller更小的，形容词比较级；smallest最小的，形容词最高级。故选A。as…as中间接形容词原级。故选A。
7．句意：它和普通的书一样小，但它仍然可以有所有的学习的东西，如课本，练习本等。
and和；but但是；or或者。“it can still have all the things for study”与前文是转折关系。故选B。
8．句意：它们可以像邮票一样制成薄片。
into到……里面；from从；up向上。根据“They can made… chips”可知，此处指被制成薄片，be made into“被制成”。故选A。
9．句意：他们只需要把正确的芯片放进电子书包。
bring带来；take带走；put放。根据“the right chip into the e-schoolbags”可知，把正确的芯片放进电子书包。故选C。
10．句意：一些人说电子教科书很容易坏，而另一些人说它们是好学生的眼睛。
if是否；what什么；that引导从句无实际意义。分析句子结构可知，空格后是一个宾语从句，且从句结构完成，用that引导宾语从句，故选C。
