我的英语不如他英文怎么说

你可以说："My Engpsh is not as good as his."

这句话的来源是英语中的比较级形式，其中 "not as good as" 意思是 "不如"。

例句：

"I'm not as tall as my sister." (我不如我的姐姐高。)
"His cooking skills are not as good as mine." (他的烹饪技巧不如我的。)
"This book is not as interesting as the last one I read." (这本书不如我上次读的那本有趣。)

注意：比较级形式也可以用 "than" 来表示比较，例如：

"My Engpsh is not as good as his." 可以改写成 "My Engpsh is not as good as his Engpsh." (我的英语不如他的英语好。)
