Answer 1

分析 本文是一段對話，是凱特博士和鮑勃之間關于收音機用途的一段對話．自從我們還年輕的時候，收音機已經改變了很多，它曾經是家庭娛樂的主要來源．現在當你打開收音機，你或者聽音樂、脫口秀或者新聞．

解答 61．has changed 考查現在完成時．根據since we were young，可知這里用現在完成時．故填 has changed．
62．to 考查固定搭配．used to do sth是固定用法，意為"過去常常做某事"．故填to．
 63．or 考查連詞．根據句意"現在當你打開收音機，你或者聽音樂、脫口秀或者新聞"，可知此處表示選擇關系，故填or．
 64．Fortunately 考查副詞．位于句首，有逗號隔開，修飾整個句子的應用副詞，故填Fortunately．
65．listening考查非謂語．enjoy后的動詞應用動名詞形式，enjoy doing是固定用法，意為"喜歡做某事"．故填listening．
66．who 考查定語從句．根據空后的have可知，此處做主語指代先行詞those，所以是定語從句，因先行詞是those，故填who．
67．while/when 考查狀語從句．句意：看起來人們只在開車的時候，才會聽收音機．故用while/when．
 68．at 考查介詞．固定短語at home意為"在家"．故填at．
69．playing 考查非謂語．have sth．doing是固定用法，sth．與動詞是主動關系，意為"使某物一直做某事"．此處表示"讓收音機一直開著"，故填playing．
70．communication考查名詞．根據句子結構可知，此處為of形式的名詞所有格，所以介詞 of之后用名詞形式，故填communication．

點評 語法填空是通過語篇在語境中考查語法知識的運用能力，在解題前應快速瀏覽短文掌握大意，在讀懂短文的基礎上，結合短文提供的特定的語言環(huán)境去逐句分析，逐題解答．扎實的語法功底加上準確的理解至關重要．
