“杭州下雨”用英语可以说:It is raining in Hangzhou.
“it is raining”是“正在下雨”的常用表达,“in”表示“在......里面”,“in Hangzhou”即在杭州。
例如:If you ask someone about the weather in Hangzhou and it's currently raining, they might say: \It is raining in Hangzhou.\
还可以用“Hangzhou is having rain.” 来表达,但“It is raining in Hangzhou.”这种表述更加常见和自然。
