1. hope表达实现的可能性较大的愿望，wish表达的愿望实现的可能性较小。因此，hope的宾语从句不用虚拟语气，wish的宾语从句可用宾语从句。
The student hopes that you can help him with his English.(can不用could代替)
They hope that they will visit China someday.(will不用would代替)
How I wish I were a bird and fly to the moon.(动词不用hope.)
2.“希望某人干某事 ”应说：wish sb to do sth.不能说：hope sb to do sth.
All parents wish their children to be happy.(动词不能用hope)
3. 在祝语中常用“wish sb +宾语补足语 ”，而hope没有这样的句型。
I wish you a happy new year.
I wish you a good journey.
4.在答语中常用hope so/hope not表达“希望如此”和“希望不是这样”
5．句型相同时可换用：
They hope to visit China.= They wish to visit China.
People should always hope/wish for the best and prepare for the worst.
