怎么把疑问句、祈使句的直接引语变为间接引语

1.一般疑问句:直接引语如果是一般疑问句,变为间接引语时,要用连词WHETHER或IF引导.主句中的谓语动词是SAID时,要改为ASKED.没有间接宾语的,可以加上一个间接宾语(ME,HIM,US等).例句:
(1)Hesaid,"AreyouinterestedinEnglish?"Heasked(me)ifIwasinterestedinEnglish.
(2)Hesaid,"Didyouseehimlastnight?"Heasked(me)whetherIsawhimlastnight.
2.特殊疑问句:直接引语如果是特殊疑问句,变为间接引语时,仍用原来的疑问词引导."WhatcanIdoforyou?"heaskedme.Heaskedmewhathecoulddoforme.
3,转换祈使句时,要将祈使句的动词原形变为带TO的不定式,并在不定式的前面根据句子的意思加上TELL,ASK,ORDER等动词,其句型是:tell/ask/ordersomeone(not)todosth.例句:
"Makesurethedoorisshut,"shesaidtoherson.Shetoldhersontomakesurethedoorwasshut.
"Don'tsmokeintheroom,"hesaidtome.Hetoldmenottosmokeintheroom.
