CET6丨IELTS丨TOEFL

 外刊例句 

As bots get smarter and more pervasive online, we humans can still console ourselves with a different discovery by Gilani: that tweets penned by humans get 19 times more likes than tweets by bots. And 10 times more retweets. So, at least in Twitter popularity, humans still beat the bots…for now.

虽然机器人变得越来越智能和普遍，我们人类仍然能够用Gilani的研究结果来自我安慰：人发的推文获得的点赞量是机器人的19倍，转发量是机器人的10倍。所以，至少在推特上，人类暂时仍略胜于机器人
