直接引语变间接引语如果是祈使句有情态动词怎么办

问题描述:

直接引语变间接引语如果是祈使句有情态动词怎么办
例如“you can sit here,Jim”the teacher said
“you must come here before five”the boss said
就是想问问那个像must,can,should是不是可以去掉,如果不去掉,又该怎么变

可以去掉.所谓祈使句,就是表示命令或请求的句子.转换成间接引语时,可以使用to do来解决.
The teacher allowed me to sit there.
The boss ordered me to go there before five.
