50. I only wish he showed half as much for his English lessons.
點(diǎn)睛
wish在表示愿望時，使用的頻率很高?？梢杂迷陉愂鼍浠蛘吒袊@句中，表示與事實(shí)相反的情況，或表示將來不太可能實(shí)現(xiàn)的愿望，因此從句中必須用虛擬語氣。如：
He wished he hadn't 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(shí)是倍數(shù)的表達(dá)法half as much as he showed（比較結(jié)構(gòu)half/a quarter/twice/three times＋as...as）的縮略表達(dá)。如：
I won't marry a man who is twice as old as me. 我不會嫁給一個歲數(shù)比我大一倍的人。
