　　英语四级经典必背500句：听力口语关键句50 　　50. I only wish he showed half as much for his English lessons. 　　四级词汇讲解: 　　wish在表示愿望时，使用的频率很高。可以用在陈述句或者感叹句中，表示与事实相反的情况，或表示将来不太可能实现的愿望，因此从句中必须用虚拟语气。如: 　　He wished he hadnt said that.他希望他没讲那样的话。 　　How I wish I were as tall as you are.我真希望和你一样高。 　　本中的half as much其实是倍数的表达法half as much as he showed的缩略表达。如: 　　I wont marry a man who is twice as old as me.我不会嫁给一个岁数比我大一倍的人。
