26、的家庭照片。根据这句话的意思可知，这句话的主语应该是 my family photos，是复数形式，因此动词 be 也应该用复数，把 is 改为 are。4句意：Mary，我需要我的笔记本，你能把它带给我吗？根据句意可知，这里的“我”在句中做的是 to 的宾语，所以应该用宾格形式。I 是主格形式，故把 I 改为 me。5句意：我有 2 个篮球。has 意思是有，它应该用于主语是第三人称单数的时候。I 是第一人称，它后面应该用 have。6句意：我有 2 个篮球和 5 张照片。photo 的意思是照片，根据句意可知，我有 5 张照片，所以应该用复数，它的复数形式是直接在后面加 s，不是加 es。

27、7句意：我有 2 个篮球、5 张照片和一个橡皮。eraser 是一个名词，意思是橡皮，这个单词的第一个音是元音发音，所以不定冠词应该用 an。故应该把 a 改为 an。8句意：我想带一个篮球去 Jim 的学校。根据句意可知，这里应该是说去 Jim 的学校，Jim是一个名词，这里应该把它改为所有格的形式，表示 Jim 的，即 Jims。9句意：他们可以每天打篮球。play basketball 打篮球，是一个固定的短语。在球类运动的前面不加冠词，所以把 the 去掉。10 句意：我非常开心，你开心吗？这句话的主语是 I，是第一人称，它后面的 be 动词应该是am，而不是 is。is 应该用于主语是第三人称单数的时候。
