put two and two together
根据现有情况推论；综合判断
- "How did you know they were having an affair?" "I'd seen them out together a couple of times, so I just put two and two together."
“你怎么知道他们有婚外情？”“我好几次见到他们一起外出，所以就这么推断。”
值得注意的是， put two and two together and make five 这个习语指的却是“听风就是雨”，比如：
- "Why in the world did she think you were pregnant?" "I was sick a couple of times, and I guess she just put two and two together and made five."
“她究竟为什么会认为你怀孕了？”“我曾呕吐过一两次，我猜她就这样想了。”

【英式英语】误解

她的朋友看到我们一同到达聚会现场，便产生了误解。
