1)"wish+宾语从句"表示不能实现的愿望,汉语可译为"可惜……"、"……就好了"、"悔不该……"、"但愿……"等。表示现在不能实现的愿望,从句的谓语动词用过去式;表示将来不能实现的愿望,用"would(could)+动词原形";表示过去不能实现的愿望,用"had+过去分词"或"(could)would + have + 过去分词"。例如:

　　I wish we could go to the seaside today.

　　I wish you told me earlier.

　　We wish we had arrived there two hours earlier.

　　2)虚拟语气在动词arrange, command, demand, desire, insist, order, propose, request, require, suggest 等后面的宾语从句中,用"(should)+动词原形"。例如:

　　I suggested that the meeting (should) be put off.

　　The doctor ordered that she (should) stay in bed for a few days.

　　They demanded that the black people should be treated as well as white people.

　　注意:insist作"力言"、"强调"解时,宾语从句不用虚拟语气。只有当insist作"坚持(应该)"解时,宾语从句才用虚拟语气。例如:

　　Mike insisted that he had never stolen anything.

　　I insisted that you give me my money back.
