正确的是：How was the weather ? （那时）天气怎么样？没有 How did the weateher 这种用法，所以不存在区别。分析：1、did 是助动词，助动词后要跟动词原形，而weather 是名词，所以 How did the weather 是错误的。2、问天气的句子是：1)、一般现在时： How is the weather ?= What 's the weather like ?2）、一般过去时，is 要改为 was ,即： How was the weather (yesterday) ?= What was the weather like (yesterday) ?3）、一般将来时： How will be weather be ( tomorrow )?= What will the weather be like( tomorrow ) ?如：1). How is the weather in your hometown? =What is the weatehr like in your hometown? It's sunny .2). How was the weather in Beijing yesterday ? = What was the weather like in Beijing yesterday ? It's very hot .
