 ♣ guess, guess at
　guess　和guess at都可表示“猜测”“猜”。其区别是：
1. guess at更强调“猜”的动作本身，含有“试猜一下”“猜猜看”的意思；而guess无此含义。例如：
　I can't even guess at her age.　我甚至连她的年纪也猜不着。
2. 当表示“猜中”时，通常用guess，而不用guess at.
 ♣ guess, conjecture, surmise
　这组动词都有“猜想”“想象”“料想”的意思。其区别是：guess指对某事并未确知的情况下，只凭想象的可能性来猜测；conjecture指凭经验从不完善、不肯定的证据中进行推断；surmise指凭直觉观察推断出有效结论，暗含具有客观态度和冷静思考的能力，往往有较充分的推测根据。例如：
　The old peasant conjectured that it would be an unusually cold winter.　那老农推测冬天将会异常地寒冷。
