我认为哈,这2个词语法袭渣上来说都是正确的!!但是 如果选择题出出来的话,他会叫你选择哪个更接近句子的意思源禅谈,这里面我认为应该选B更加恰当,首先刚靠读,如雹碰果读感觉不出来,那就只能2个词比较了,hard working他可以做形容词,比如说peole often use hard working horses for what what!!! 但是绝对不能说people often use horse for hard working,只能用hard work!
work hard 是动词芹拍。嫌大羡如 He works very hard. 侧重于动作hard-working 则是纯仿碧属形容词 如 He is a hard-working people. hard-working 修饰people
A是指此圆形容工作人的难度,He has a hard working this morning
B指宴圆形容工作的难晌扒塌度,That is a hard work.
work hard,山陆hard work,hard-working是源衡易逗裂顷混词组,答疑解惑
A是形容词~B是动词!!!
