1. Q: To be here at Christmas time is a dream that has come true. 请分析一下本句的结构。
A：本句是一个主从复合句。句中To be here at Christmas time是动词不定式作主语，is a dream是系表结构，that 引导的是定语从句，修饰dream。关于定语从句会在17单元学到。
2. Q: Some people even put up stocking for their pets as well. 句中as well表示"也"与其它几种表达方式有什么异同？
A: 汉语的"也"英语可用too, also, as well和either表示，其区别是：too是普通用词，常置于句子末尾且用逗号与句子隔开；also是比较正式的用语，它一般位于be动词、情态动词、助动词等之后，行为动词之前；as well用法与too相同，通常位于句尾，但前面一般不用逗号； either表示"也"时，一般只用于否定句中，且置于句子末尾，用逗号与句子隔开。试比较：
I would like to go fishing on Sunday, too.
He has also been to the top of Mount Tai.
He is a teacher, and a writer as well.=He is a teacher, and he is a writer, too.
The students didn't work out the problem. The teacher didn't, either.
3. Q: Even though Father Christmas is no longer living, ... even though引导什么从句？
A: even though作为连词，意为"虽然......；尽管......"，引导让步状语从句。如：
Even though he is poor, she still loves him.
4. Q: It is said that ... she was to have this special boy. 句中was to have是什么结构？
A: "be to + 动词不定式"这种结构常用来表示按计划安排将要发生的事情，是将来时态的另一表达形式。如：
They are to arrive in Beijing at 4 o'clock this afternoon.
The new shop is not to be opened untill next week.
