38、om Aunt Jess. I looked at the key more closely on by his myI realized it was a car key. This was best present.

39、改 为 them。考查代词。分析句子结构可知，but 连接两个并列分句，此处并不是一个定语从句，所以把 which 改为 them，指代my birthday presents。is 改 为 are。考 查主谓一致。which 引导的定语从句修饰先行词books，关系词在从句中作主语，且先行 词 books 是复数，所以把 is 改为 are。seventeen 改为 seventeenth。考查序数词。此处表示“在我第十七个生日” ，应该用序数词，所以把 seventeen 改为 seventeenth。find 改为 found。考查时态。作者在回忆往事，表示 发生在过去的事情，应 用一般
40、过去时，所以把 find 改为 found。hand 前的 on 改为 by。考查介词。 “生日快 乐，我亲爱的侄子！”这些字是手写的。on hand“在手头，在近旁” ，by hand“手工” ，故把 on 改为 by。his 改为 my。考 查代词。根据上文可知， 这 里表示“它来自我的姑姑 Jess”，所以把 his 改为 my。but 改为 and。考查连词。我更近地看着这把钥匙，然后意识到它是一把汽车钥匙。此处表示顺承，所以把 but 改为 and。best 前加 the。考查冠词。这是我收到的最好的礼物。最高级前面用定冠词 the。generously 改为 generous。考查词性转换。修饰名词用形容词，所以把 generously 改为 generous。
