这里要表述的黑马指最近刚取得或将要取得成功的新人，用英语表达是 dark horse，记得不要写成 black horse，寓意：
1、a little known, unexpectedly successful entrant 一个鲜为人知，出人意料的成功入围者 2、someone who was previously unknown, but suddenly emerges into prominence 以前默默无闻，但突然显赫起来的人 3、someone who keeps their skills and ideas secret and surprises others by doing something unexpected 一个对自己的技能和想法保密的人，通过做一些意想不到的事而使别人感到惊讶的人 4、a person who wins a race or competition though no one expected them to win 胜利者在比赛或竞技中获胜的人，尽管没人预料到他们会赢
例如： 1、Don't think you'll beat him easily, he may be a dark horse. 不要以为你会轻而易举地胜过他，他可能是出人意料的高手。 2、Though many favoured the bigger teams to win the competition, the local team was a dark horse, and surprised everyone with their dazzling performances. 尽管许多人都偏爱大球队赢得比赛，但当地队却是匹黑马，他们令人眼花缭乱的表演让每个人都感到惊讶。 解析：although 和 though 同义，在一般情况下，可以互换使用。只是 though 较普遍，常用于非正式的口语或书面语中，而 although 则较为正式。另外 although 语气比 though 重，常用以强调让步概念。
3、Everyone thought that the seasoned campaigner would win the election this time, but the new candidate turned out to be a dark horse and beat him comfortably. 所有人都认为这位经验丰富的竞选者这次会赢得选举，但新候选原来是一匹黑马，轻而易举地击败了他。 4、While Dennis is the favourite to win the contest, our own local boy Harris could turn out to be a dark horse with his talent and skills. 虽然丹尼斯是最有希望赢得比赛的人，但我们当地的男孩哈里斯凭借他的天赋和技能可能会成为一匹黑马。
