英語四級經典必背500句：聽力口語關鍵句50 　　50. I only wish he showed half as much for his English lessons. 　　四級詞匯講解: 　　wish在表示愿望時，使用的頻率很高。可以用在陳述句或者感嘆句中，表示與事實相反的情況，或表示將來不太可能實現的愿望，因此從句中必須用虛擬語氣。如: 　　He wished he hadnt said that.他希望他沒講那樣的話。 　　How I wish I were as tall as you are.我真希望和你一樣高。 　　本中的half as much其實是倍數的表達法half as much as he showed的縮略表達。如: 　　I wont marry a man who is twice as old as me.我不會嫁給一個歲數比我大一倍的人。
