3.But there is nothing in the fridge.冰箱里什么都没有(教材P30)
nothing是不定代词,意为“没有什么”。nothing作主语时,谓语动词用单数形式。修饰不定代词的形容
词,应放在不定代词之后。如:
Nothing can stop Simon from studying hard. 没有什么能阻止西蒙努力学习。
【拓展】none和nothing的区别主要有以下四点:
①none既可指人,又可指物,而nothing只能指物。
②none既可单用,也可加of...,而nothing不能再在后面加上of...(固定短语除外)
③none指数量,所以回答how many/much的问句; nothing指概念,所以回答what的问句。
