Answer 1

答案：
解析：

　　1．into　與前面的changed構(gòu)成詞組change sth．into sth．。

　　2．which　把信號重新轉(zhuǎn)換為字母的是前面提到的fax machine，所以逗號后面的句子是一個非限制性定語從句，用which引導(dǎo)。

　　3．how　imagine接的是一個賓語從句，只有how后面才能接形容詞引導(dǎo)這類從句。

　　4．countries　空后的China和Japan是“國家”。

　　5．posting　與作主語的動名詞短語sending a fax對應(yīng)。

　　6．take　“某事要花多長時間”的動詞要用take。

　　7．If　此處的從句是后面主句情況出現(xiàn)的條件。

　　8．be received　a fax是被人接收的，所以用被動語態(tài)。

　　9．careful　be是系動詞，后面接形容詞作表語。

　　10．than　連接兩個不定式短語構(gòu)成比較結(jié)構(gòu)。
