virtual中文意思是“真实的,虚拟的”,可我怎么觉得这两个意思是相反的?请问怎么辨析这个单词的词义?

virtual
adjective
1 [before noun] almost a particular thing or quality:
例句：Ten years of incompetent government had brought about the virtual collapse of the country's economy.
War in the region now looks like a virtual certainty.
2 describes something that can be done or seen using a computer and therefore without going anywhere or talking to anyone:
例句：virtual shopping/banking
virtually /ˈvɜː.tju.ə.li/ US /ˈvɝː-/
adverb
almost:
例句Their twins are virtually identical.
That wine stain on my shirt has virtually disappeared.
让我们看看这个剑桥高阶词典上的解释吧!英英词典才是学英语的至宝!
下面请看我的翻译和分析
1.adjective,[before noun] almost a particular thing or quality.
形容词,用在名字前面,做前置定语,这里的意思是指“一个特定的事物或是品质!”,对应中文意思的“真实的”
2 describes something that can be done or seen using a computer and therefore without going anywhere or talking to anyone
这里是指一件可以用电脑完成,而且不用去任何其他地方就能完成的事情,这是例子,virtual shopping/banking,中文是“（虚拟的)网络购物,（虚拟的）网上银行”,这里对应中文意思的“虚拟”,也可以说网络那方面的东西,如“虚拟世界（网络世界,与真实世界相对应）”
adverb
almost,还有一个意思就是用作副词,做“大概,几乎”的意思!这个副词词性是不经常用的!
学英语的话,到了一定程度,最好还是弄一本英英词典!这样会帮助很大的!
希望可以帮到您!
