解析:
1.into 与前面的changed构成词组change sth.into sth.。
2.which 把信号重新转换为字母的是前面提到的fax machine,所以逗号后面的句子是一个非限制性定语从句,用which引导。
3.how imagine接的是一个宾语从句,只有how后面才能接形容词引导这类从句。
4.countries 空后的China和Japan是“国家”。
5.posting 与作主语的动名词短语sending a fax对应。
6.take “某事要花多长时间”的动词要用take。
7.If 此处的从句是后面主句情况出现的条件。

9.careful be是系动词,后面接形容词作表语。
10.than 连接两个不定式短语构成比较结构。
