选择题：Kuming is_____ city that thousands of people visit it every day.

D.

so 修饰形容词

such 修饰名词（这里和a beautiful修饰city）

你也可以记，肯定是such a ...，不会是so a ...

D.such a beautiful
昆明是一个如此美丽的城市以致于每天都有成千上万的游客;

thousands of people visit it every day. 是个状语从句.

So beautiful(adv放在asj之前,中间没有a)

D
such +名词+that
so+adj，adv+that
kuming is so beautiful a city that……

A
so...that 为固定搭配
city 是可数名词 所以加a
