17．We can see lots of information on the computer．（改为被动语态）Lot's of information canbeseenon the computer．
分析 在电脑上我们看到许多信息．
许多信息可以在电脑中被看到．
解答 答案：be seen 第一句中"We can see…"can为情态动词，第二句中把第一句动作的承受者lots of information作为主语，这里要采用被动动态，句子中有情态动词can，被动语态为can+be+过去分词，see的过去分词为seen，故填：be seen
点评 考查被动语态，根据句子意思以及采用的时态来确定被动语态的类型，句子中有can，其被动语态为can+be+过去分词．
