which從句介紹 講解從句

1、which前面有逗號，逗號前面是個名詞，which就近指代那個名詞。Tankfield emailed Pea some photos, which did not cheer Pea h就近指代photos，定語從句中謂語動詞did not cheer (Pea up)的發出者即從句主語即先行詞photos，是photos沒讓豌豆家屬高興起來。

2、Tankfield emailed Pea some photos, which Pea did not find h就近指代photos，photos是定語從句中的賓語，把定語從句還原成一個完整句就是Pea did not find the photos interesting。

3、可以看到，上面兩個句子都可以以that為關係代詞改寫，即Tankfield emailed Pea some photos that did not cheer Pea up.)Tankfield emailed Pea some photos that Pea did not find interesting.改寫與原版區別在哪兒，就在一個逗號。which前面是名詞，名詞和which之間沒逗號的，在GMAT語法裏算錯。
