【洋人网站, 专家答疑】 Using “ones” with “these” can seem redundant and unnecessary, but still, it’s not necessarily grammatically incorrect. So, you’ll likely continue to hear the phrase often, both in standard American English and British English, the phrase being more common in the latter. (将“ones”与“these”一起使用可能看起来是多余和不必要的,但它在语法上并不一定是错误的。因此,你可能会继续经常听到这个短语,无论是在标准的美式英语还是英式英语中,后者(仅these)更常见。[百度翻译] ) 我个人看,these ones 可以用,与第一个图this one, 类似。 个别场景下these ones中ones是必要的,要看具体情景(为区别一大堆东西)。
