Answer 1

小题1:called
小题2:was invented
小题3:to work
小题4:would be
小题5:incorrect

试题分析：
小题1:called考查动词。句意：最近我听到一首歌叫心弦。Called 分词做后置定语用来修饰 a song.
小题2:was invented  考查动词的语态。句意：电话在汽车之前发明的。电话与发明之间是被动关系。所以用被动语态的一般过去时，was invented.
小题3:to work考查动词的用法。句意：工厂的工人每天工作16个小时。Make sb do 让某人做某事，被动语态 sb be made to do 被省略的to一定要加上。
小题4:would be考查动词的时态。句意：他说将来他会成为一名科学家的。主语的时态是一般过去时所以从句的时态也要用相应的过去时，some day 表示将来的某天，所以用一般过去将来时。
小题5:incorrect考查形容词。句意：请保持干净，扔垃圾是不正确的。这里是句式it is +形容词+to do,故用形容词。
