I need a pen to write 和 I need a pen to write with那句对?为什麽?

第二句对,因为是短语是write with a pen,不是write a pen,所以这句动词不定式连接时,不能把with省去
祝你更上一层楼,有不懂的可以再问哦
再问： We hope they have a warm house to live in and have warm clothes to wear。 和We hope they have a warm house to live and have warm clothes to wear。哪句对
再答： 第一句啊,语法是一样的内容啊,live in a warm house,介词in不能省
再问： 摁摁 知道了
