答
I really wonder why__he sent me so many presents_when_we worked together.可以解释一下吗这句话的中文翻译是：我真的搞不明白，为什么我们一起工作的时候他送个我这么多礼物。这是一道单选题，Awhy ,when B why ,since Cwhenbefore Dthat, after 清从语法角度解析一下，谢谢。这句话的成分是：主语+谓语+宾语从句。I是主语，wonder 是谓语，wonder 的内容就是why引导的宾语从句。这里有一个语法点，wonder 后面的宾语从句一般情况下由why引导欢迎追问那么什么情况第二空可以选since呢？万分谢谢。it is +时间+since+句子。例如：It is two years since I graduated from school.
