下面的句子出自徐广联主编《当代高级英语语法》(精装版):
The city is much different from what it was twenty years ago. 这座城市和20 年前大不一样了。
但我们的老师说,You are much different from your brother 是错的,上面这两个句子有区别吗?
你的老师是对的,徐广联主编《当代高级英语语法》(精装版)的以下句子确实有错,至少是不妥:
The city is much different from what it was twenty years ago. 这座城市和20 年前大不一样了。
根据现代英语语法,much 修饰 different 时,只限于否定句和疑问句,通常不用于肯定句。
比如《朗文当代英语词典英汉双解第4版》就在 much 词条给出了以下用法提示:
Do not use much before adjectives in sentences that are not questions or negative sentences. Use very. 如果不是疑问句或否定句,形容词之前不要用 much,而要用 very:
Tea and coffee taste very different (NOT Tea and coffee taste much different). 茶和咖啡味道非常不一样。
