按括号中的要求完成改写后的句子，每个空格填一个单词。
【小题1】Mr. Smith is doing morning exercises now. (改为否定句)
Mr. Smith isn’t doing How long morning exercises now.
【小题2】The old man has been in Jinan for about 50 years.（对划线部分提问）
if wanted Thanks to has the old man been in Jinan?
【小题3】My friend asked me:“Do you want to go there?”(改写句子，句意不变)
My friend asked me allowed is I 　 to go there.
【小题4】Because of your help, we could finish the work easily. (改写句子,句意不变)
　 　 your help, we could finish the work easily.
【小题5】Parents will allow teenagers to relax themselves if they finish their homework. (改写句子,句意不变.)
Teenagers will be 　 to relax themselves if their homework　
finished.

解析：【小题1】含有be动词改为否定句在其后加not，故本题空格处填isn’t doing。【小题2】对时间长度提问的用疑问短语多长How long。【小题3】一般疑问句改为间接引语需用if来连接，主句为过去时，从句要用过去时，故用want的过去式wanted，故本题空格处填if wanted。【小题4】本题的含义也可以为多亏你的帮助，我们很轻松地完成了工作，thanks to可以表示多亏的含义，故本题空格处填Thanks to。【小题5】本题改写的句子都为被动的意思，用被动结构be+动词过去分词，故本题空格处填allowed is。
