1.宾语从句的主语:一随主,二随宾,三不变.
e.g.(1)Shesaid"Iwillgohome."
改:Shesaidthatshewouldgohome.(一随主)
(2)Shesaidtome"Youcangowithme.".
改ShesaidtomethatIcouldgowithher.(二不变)
(3)Shesaidtome"Hewillgohome."
改Shesaidtomethathewouldgohome.(三不变)
2.宾语从句中注意时态
1.若主语为一般过去时,则宾语从句的时态要变为过去的某一时态.
e.g.(1)Hesaid"Iwilgohome.“
改Hesaidthathewouldgohome.(一般将来时改为过去将来时)
(2)Hesaid"Ihavehadlunch."
改Hesaidthathehadhadlunch.(现在完成时改为过去完成时)
(3)Hesaid"Iknowalotabouttheteacher."
改Hesaidthatheknewalotabouttheteacher.(一般现在时改为一般过去时)
(4)Hesaid"Ihadlunch."
Hesaidthathehadhadlunch.(一般过去时改为过去完成时)
(5)Hesaid"Iamplayinggames"
改Hesaidthathewasplayinggames.(现在进行时改为过去进行时)
特殊Hesaid"Theearthgoesaroundthesun."
改Hesaidthattheearthgoesaroungthesun.(当直接引语中表示客观事实时,时态不受主句影响)
3.直接引语变间接引语时,要注意时间状语的改变.
e.g.Hesaid‘Iamlisteningtomusicnow."
改Hesaidthathewaslisteningtomusicthen.(此句中now改为then)
后面不举例了,时间状语按下面改就对了
now=then
today=thatday
tonight=thatnight
thismorningweek=thatmorningweek
tomorrow=thefollowingnextday
yesterday=thedaybefore
lastmouth=themonthbefore
ago=before
here=there
(上面左为直接引语中的时间状语,右为间接引语的时间状语)
4.最后是指示代词要变
this改为that
these改为those
像你说的
有个规则wether+or
有了or就不能用if只能用wether
不懂再问
望采纳
