The more you practice, the better you get. Which/Who is + 比较级 Which is larger, China or Canada
注意事项 比较对象一致 Her English is better than mine (NOT me). 避免双重比较 more better → better (X) than后接代词 He is taller than I (am). / than me. 比较范围限定 Shanghai is larger than any other city in China.副词比较级 She runs faster than I do. less + 原级表示较低程度 This problem is less difficult than that one. 1、形容词比较级作定语时，通常不直接修饰名词（a more interesting book √） 2、在比较结构中，常用助动词代替前面出现的动词（She speaks English better than I do） 3、某些形容词本身具有比较含义（superior, inferior, senior, junior）后接to而不是than
