请根据句意用所给单词的适当形式填空。
【小题1】The teacher devoted his lifetime toteaching (teach) his students.
【小题2】While watching (watch) the programme, the children felt excited.
【小题3】When we got to the cinema, the film had begun (begin).
【小题4】When I was young, my teacher told me that the earth goes (go) around the sun.
【小题5】Titanic is a romantic film directed (direct) by James Cameron

解析：【小题1】devote sth to短语中的to为介词，所以后面跟动词作宾语时要用动词的ing形式；故答案为teaching【小题2】本句省略了they were；while引导的时间状语从句的逻辑主语和主句主语一致，且从句中含有be动词，可省略从句中的主语和be动词，故答案为watching【小题3】电影开始的时间要早于我们到达影院的时间，所以用过去完成时；故答案为had begun【小题4】直接引语变为间接引语时，如果转述的内容为客观真理时，间接引语中时态不需要发生改变故答案为goes【小题5】film和direct之间存在着逻辑上的动宾关系，即过去分词短语做后置定语；故答案为directed

这个问题我还想问问老师呢
