As soon as people visited the exhibition, their eyes were caught by a picture which③ was hung on the wall. The horse drawn in the picture was exactly the very one that④ was galloping (奔驰) like a real horse. Many people believed it was the best picture that⑤ they had ever seen. However, Mary wasn't born a good painter but one whom⑥ teachers taught to practise drawing for many hours every day. 悟语法 ①whose引导定语从句，且在从句中作定语，先行词是Mary； ②who引导定语从句，且在从句中作主语，先行词是a model student； ③which引导定语从句，且在从句中作主语，先行词是picture； ④that引导定语从句，且在从句中作主语，先行词是the very one； ⑤that引导定语从句，且在从句中作宾语，先行词是the best picture； ⑥whom引导定语从句，且在从句中作宾语，先行词是one。 慧学语法——在归纳演绎中学通 一、定语从句的相关概念　 复合句中对名词、代词、名词短语或句子进行修饰、限定的从句叫定语从句。被定语从句修饰的名词、代词等被称为先行词。 1．定语从句分为限制性定语从句和非限制性定语从句。 (1)限制性定语从句：所修饰的词表示一个特定的人或东西。如果去掉它，被修饰的词就失去意义，句子就不能成立或不完整。 (2)非限制性定语从句：由一个逗号将从句与先行词隔开，对所修饰的词作进一步的说明。如果去掉它，句子的意思仍然完整。 2．定语从句的关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as；关系副词有when, where, why。关系词通常有下列作用：引导定语从句；代替先行词；在定语从句中充当一个成分。 本单元主要介绍的是关系代词引导的定语从句。 二、关系代词引导的定语从句　 [先感知] ①(教材典句)The digital age also enables us to find people who share our interests, such as collecting model cars or playing an unusual instrument. ②(教材典句)What if the only way of getting news from faraway friends was writing letters that took ages to be delivered? ③I know the person whose house was destroyed in the earthquake. ④Social media like blogs has come between us and the friends whom we love. ⑤“Sharing” our experiences on social media is not enough to express the values which matter most to us. ⑥“Liking” our friends' photos online does not develop the connection which we share. [会发现] (1)句①④的先行词指_____，关系代词在从句中分别作______、______
