指将来才用4个情态动词+do的,不晓得这里怎么理解为是指将来的,求指教下

答案

上午的那个看起来不太清楚,你看这个资料就很明显了,希望对你有所帮助.
由wish引起的表示愿望的虚拟语气：
 A．用wish表示对现在的愿望时,它所引起的宾语从句中谓语动词形式为：过去式（be动词用were）. 
B．用wish表示对将来的愿望时,它所引起的宾语从句中谓语动词形式为：would,could,might+ 动词原形. 
C．wish用于对过去的事实表示一种不可能实现的愿望时,宾语从句中的谓语动词形式为：had+动词过去分词或could,would + have +动词过去分词. （这里不用might）
The picture exhibition bored me to death; I wish I had not gone to it. 
---“I let Joe borrow our radio for the afternoon.” 
---“That’s all right,but I wish he would buy one of his own.” 
I wish that he weren’t so lazy. 
“I_ longer this morning”是wish后的宾语从句,然后从句子“but I had to get up and come to class.”我们可以看出,这件事虽然是在今天,但是已经是过去的事情了（后面用的是过去时）.所以本题就属于wish用法的第二种情况,所以这个题选D.
翻译过来就是：今天早上我本来想睡久一点的,但是我要上学不得不起床了.
