what is this in English?It is a pen而不是It is a pen(英语)急what is this in English?It is a pen而不是It is pen(英语)

问题描述:

what is this in English?It is a pen而不是It is a pen(英语)

what is this in English?It is a pen而不是It is pen(英语)

可数名词前要有冠词,所以it is a pen正解

pen是可数名词,可数名词单数前一般要加冠词,a是冠词。所以是It is a pen而不是It is pen,

这是英语的表达方式,基本上名词单数形式不能单独存在,需要修饰词(通常是定冠词,不定冠词,物主代词等).

好,一样
