为什么He said he must leave early等效转换是He said he would have to leave early?而不是He said he had to leave early
为什么这里have to表示将来要用将来时啊,在We have to leave early tomorrow中have to同样是表示将来,却没用will have to

He said he must leave early等效转换是
He【 said 一般过去时】he 【would have to 过去将来时】 leave early
即,过去说他将要做某事.
时态搭配原则：
主句用过去时态,从句只能是过去的某种时态形式【表示客观事实和真理的情况例外】

为什么He said he must leave early等效转换是He said he would have to he said he must leave early 的同义句he said he would have to lea he said he must leave early 此句的同义句可为He said he had got to le He said he would leave tomorrow.为什么leave不用过去式 Must he leave early? He must leave early He said that he would have to work on Sunday. 同义句转换：He said he would no longer live here.He said he()live he said he would come to my home in a week .为什么是填would come He said he would like to have a glass of milk before he went 改间接引语是He said he would call me tomorrow 还是He said he called He said to me,"Would you like to go swimming?"句型转换成He asked
